CONSTRUCTION OF BALLNUTS The ballscrews for X, Y and Z axis are all 45mm diameter with a 16 pitch. The major difference with the ballscrews on the NH5000 (and NV5000) is that the ballnut is a single piece construction. The backlash on the new design is compensated for by measuring the starting torque on the screw, then either increasing or decreasing the size of the balls.
On the two piece designed ballnut, preload was compensated for by a ground shim plate installed between the two pieces of the nut. This caused the force from the grooves to be applied on the outer, upper edge of the ball bearings.
By utilizing the correct size balls, force is applied to all four corners by the grooves in the screw. It is more difficult to machine the actual threads of the screw, since even pitch and finish is critical, but time is saved on the actual assembly of the ballscrew, and there is no loss of accuracy or repeatability.
Y-AXIS BALLSCREW The Y-Axis construction on the NH5000 was designed to reduce the need for the Dynamic Thermal Displacement Control. The fixed end of the ballscrew is now at the motor side, on the upper part of the column.
The ballnut is stretched from the lower Y nut.
The reason that the need for the DTC option is reduced with this design is that with the fixed end of the Y-axis ballscrew being at the top, the ballscrew will expand downward when it heats up. Conversely, when the column
heats up, it will expand upward. Since the fixed end of the ballscrew is located a long way from the X-axis linear guide (where the column rests), the ballscrew can develop up to 3 times as much heat as the column and not show the effects of thermal expansion.

The new column is designed to provide little interference for fixtures but still provide the rigidity expected from Mori Seiki. All covers inside the machine were designed with chip removal in mind. This machine also offers optional chip augers on both sides of the table to move chips into the conveyor, which is located in the front of the machine. The chip conveyor and coolant tank is easily moved in and out of place by one person for maintenance or cleaning purposes.
CONSTRUCTION The NH5000 is constructed using a three-piece level design, like the SH5000/SH-503/SH-403 designs. All axes are designed using THK linear guides. The X-axis uses a THK/SNS45LC2QZSSHHC0E+1460LHE-II, the Y-axis a THK/SHS45LR2QZSSHHC0E+1200LHE-II and the Z-axis a THK/SNR45LC2QZKKHHC0E+1725LHE-II linear guide. The ballscrew for all three axes is a 45mm diameter by 16 pitch lead. X-axis has 630mm of travel, Y-axis 600mm and Z-axis has 670 mm.
Note in the picture above that the machine also has a new design for chip removal. There are two chip augers on either side of the table that run from under the column all the way through the machine, including the setup station. There is also a conveyor located between the B-axis and the spindle to move the chips from the area inside the cutting envelope. This “triple trough” design is for maximum chip removal while maintaining high rigidity in the machine base.
The ways for each axis are covered with a new type sliding cover. The material is like a spring steel, so anything dropped on it will not dent. It is also designed to flex when chips get under the sliding seals instead of building up and separating the covers as in the past.
The X/Y cover, when installed or when being replaced, must be indicated in to ensure flatness. It is adjustable by loosening the screws on the slotted mounting brackets, adjusting the position, then tightening the bolts back. In the picture below, you can see the pantographic support of the X and Y axis.

CLEANING THE AIR FILTER If the air filter element is clogged, the pressure of the air supplied to the actuators is decreased, causing their operation failure. Therefore, the air filter element should be cleaned at regular intervals or the element should be replaced if it is heavily clogged. The air filter is equipped with a float type automatic discharge unit. Usually, the drain is automatically discharged through the discharge port. However, if the drain is not automatically discharged or if foreign matter has accumulated at the bottom bowl, operate the drain cock manually to discharge the drain.
Manual Discharge of the Drain When the accumulation is not discharged automatically, or when foreign matter has accumulated at the bottom of bowl Turn the manually operated drain cock at the bottom of the air filter counterclockwise to discharge the drain.
Cleaning the Air Filter Air Filter If the air filter element is clogged, the air pressure supplied to the actuators is reduced, causing their operation failure. Therefore, the air filter element should be inspected at regular intervals. Every 1000 hours of operation 1) Turn off the power.

INSTALLATION DRAWING Make sure there is sufficient maintenance area for opening the CNC and electrical cabinet doors, for pulling out the coolant tank and chip conveyor, etc.
Unit: mm
(1) Separatedarated units (step-down transformer, etc.) must not be located at exact position as shown in the drawing as long as interference is avoided. (2) 30-tool specification
FOUNDATION DIAGRAM (1) Select a place that can support the weight of the machine. (2) To obtain and maintain the intended levels of accuracy and performance from the machine over a prolonged period of time, perform foundation work carefully and pay attention to machine installation. Unless foundation work is performed according to the foundation diagram, it will adversely affect the accuracy (static and dynamic) and the life of the machine. Unit: mm
ENVIRONMENTAL REQUIREMENTS Consider the following requirements when selecting a site to install the machine. CAUTION
NOTE
Install the machine at a site where the ambient temperature remains within the range 10 to 35GC, the humidity does not exceed 75% RH (with no condensation), and the altitude is lower than 1000 m. Failure to comply with these conditions could cause trouble in the electrical systems of the NC unit and peripheral devices and lead to machine failure.
Install the machine at a site where neither it nor the NC unit is subject to direct sunlight. Direct sunlight will raise the temperature and cause thermal displacement, adversely affecting machining accuracy.
CAUTION
The machine must not be installed at a site subject to excessive vibration (greater than 4.9 m/s2). Excessive vibration could lead to machine failure and will adversely affect machining accuracy.
CAUTION
(1) Choose an installation site that is as free as possible from dirt, dust, and mist. If dirt and dust adhere to the cooling fan fitted inside the machine its cooling capability will be impaired and this could lead to machine failure. (2) Install the machine at a site where it will not be reached by chips, water, and oil scattered from other machines. These could cause machine failure.
NOTE
Make sure the floor is strong enough to support the machine. The floor must not be sloped or irregular in any way. Twisting or other distortion of the machine will adversely affect machining accuracy.
CAUTION
When installing the machine, refer to the installation drawing and other instructions and provide sufficient maintenance area to allow the chip conveyor (if featured) and coolant tank to be removed, and the electrical cabinet door to be opened and closed, without difficulty. If you do not provide sufficient maintenance area it will not be possible to carry out maintenance work properly and the life of the machine will be shortened. Refer to the INSTALLATION DRAWING in the DRAWINGS published separately.
FOUNDATION WORK For the installation of the machine, conventional foundation work using foundation bolts is not necessary due to its machine construction (three-point support structure) and the rigidity of machine. Normally, it is good enough to support the machine if the thickness of the floor concrete is 500 mm or more. However, if the ground does not have sufficient strength and is not capable of absorbing the vibrations of other machines, the foundation work for absorbing the vibration is necessary. Consult a civil engineer to determine the number and depth of piles and concrete thickness because they differ according to the ground condition. Machine

Select a primary power cable by accurately calculating the power supply capacity at the supply side. Using an inappropriate cable could lead to fire, injury, or damage to the machine. (2) Do not install the machine close to major sources of electrical noise, such as electric welders and electrical discharge machines. If the voltage supply is not stable, the machine may malfunction, leading to accidents involving serious injuries or damage to the machine. If noise is continually entering the machine through power cables, it can cause breakage or burning of electrical or electronic devices inside the electrical control panel and this can lead to fire.
NOTE
*
Voltage fluctuation (drop) during spindle or servo system acceleration must be less than 7%. If voltage is lower than 200 V during servo system acceleration/deceleration, actual acceleration/deceleration time may be elongated than the theoretical time.
Power Cable Prepare a power cable that can supply the total power capacity required by the machine. For the power capacity required by the machine, refer to APPENDIX 1 "POWER CAPACITY TABLE" in this manual. The cable type, wire thickness, and other cable specifications vary according to the insulation class, ambient temperature, temperature correction coefficient, and wire laying conditions.

Grounding Cable For the grounding cable, consult the cable manufacturer to select the one which is sufficient to take earth for the machine to be installed. When selecting the grounding cable, observe the applicable local regulations where the machine is installed.
DANGER
(1) Be sure to carry out the grounding work. If the grounding work is not done, there will be a danger of electrocution. (2) The grounding wire should be as short as possible and should have the same thickness as the power wires. The grounding resistance should be 100 : or less. If the grounding is ineffective, there will be a danger of electrocution.
WARNING
Do not connect any other grounding wire to the ground. If a machine such as an electric welder or electric discharge machine is grounded to the steel reinforcing rods in the reinforced concrete structure of the plant, do not connect the grounding wire of the machine to the reinforcing rods too. Unless the grounding wire is connected to an independent ground, the machine could malfunction due to noise from other machines, leading to accidents involving serious injuries or damage to the machine.
Meaning of "Leak Current" Indoor electrical wiring and equipment are "insulated" in order to prevent current leakage. However, when the insulation becomes old or damaged, or when the wires/equipment are exposed to water, current leaks out and a "leak current" is generated. Since leak currents can cause accidents that endanger human life, such as electric shock and fire, due care is required. Particular care is necessary when using electrical equipment in locations where there is exposure to water (where coolant is used, for example).
Meaning of "Electric Shock" When a person touches wiring or electrical equipment from which current is leaking, electricity flows through that person's body to the ground. This is an "electric shock." If the current is weak, the result is nothing more than a "shock" in the commonly understood sense, but if it is strong, the life of the affected person may be endangered. Note also that water on the body of the person subject to the shock will allow the electricity to be conducted more easily, and for this reason you must take particular care not to touch electrical equipment with wet hands.
Main Breaker for the Shop Power Distribution Board Use a breaker for an AC inverter as the main breaker on the shop power distribution board. If another type of breaker is used, it may be actuated by the high-frequency leak current specific to AC inverters. NOTE
Leak current will not adversely affect operators.
Meaning of "Breaker" This is a device that automatically shuts off the current within 0.1 seconds in the event of an abnormal current flow such as a leak current. By installing a breaker in the distribution panel, it is possible to prevent accidents due to current leakage from electrical equipment and devices. Since machine tools use many AC inverters, you must select a breaker of a type that will not be erroneously actuated by the high-frequency leak current from the inverters. Select the correct circuit breaker and power distribution board capacities by consulting the electric part manufacturer based on the current consumption calculated by the following formula. Current (A) =
*
Total capacity (kVA) K 1000 3 K 200 (V)
K 1.25*
Allowance for selection For the power capacity required by the machine, refer to APPENDIX 1 "POWER CAPACITY TABLE" in this manual.
Compressed Air Supply Select a compressed air supply that can supply the required volume of compressed air at the required pressure. For the selection, consult the compressor manufacturer. CAUTION
(1) Use only clean and dry air, 0.7 MPa, 10GC or less. If you use air that is moist or has a high concentration of dust, the pneumatic devices could malfunction, causing damage to the machine. (Applies to machines with pneumatic devices) If the compressed air quality is not within the specified range, use a line filter, dryer, etc. between the machine and the air source. (2) The pressure setting of the compressor should be in the range from 0.5 to 1.0 MPa. If the setting is higher than 1.0 MPa, pneumatic actuators used in the machine could be damaged.
Hoses for Supplying Compressed Air Select hoses for supplying compressed air that can comfortably withstand the compressed air pressure. For advice on the selection, consult the hose manufacturer. Compressed air supply port size: Rc 3/8
AFTER RECEIVING THE MACHINE CAUTION
When transporting the machine or if the machine is not installed immediately after its delivery, store it in a place where the ambient temperature remains within the range
20 to 60GC and the humidity does not exceed 75% RH (with no condensation). Failure to comply with these conditions could cause troubles in the electrical systems of the NC unit and peripheral devices and lead to machine faults.
When the machine is delivered, pay attention to the following points. If the machine is delivered in a package, check the external frame of the package. If the machine is delivered without a package, check the external appearance of the machine. NOTE
If the package frame is damaged, contact Mori Seiki before unpacking the machine. If the machine appearance shows damage, contact Mori Seiki, leaving the damage as it is.
CAUTION
If the machine is not moved to the installation site immediately after its delivery, keep it in a location not exposed to the elements and not subject to dust, dirt, or mist. Leaving the machine in such places will cause rusting or corrosion.
CARRYING THE MACHINE When the machine is delivered to your shop, Mori Seiki's service technicians will install the machine at the designated place. Refer to the information below if you move the machine after initial installation, for example due to a floor layout change. If it becomes necessary to carry the machine due to relocation of the plant or selling of the machine, contact Mori Seiki.
Preparation Make the following preparations before moving the machine. 1) Before turning off the power, move each axis to the position where it should be fixed. 2) Turn off the main switch on the electrical cabinet.
3) Turn off the main breaker on the shop power distribution board. 4) Disconnect the power cable and the grounding wire. 5) Fix the machine units with transit clamps. 6) Turn off the compressed air. 7) Remove the compressed air supply hose. 8) Disconnect the cables of the coolant motor and chip conveyor motor. 9) Disconnect the cables and pipes of the oil cooler (fan cooler). 10) Remove the coolant tank and the chip conveyor from the machine. 11) Drain the coolant from the coolant tank. 12) Remove the jack bolts.
Carrying the Machine by Hoisting Observe the following cautions when carrying the machine by hoisting.
WARNING
(1) Only a qualified technician should perform machine hoisting work. Operation of the crane or forklift by a person unfamiliar with safe operation practices could lead to accidents involving serious injuries or damage to the machine. (2) Use only wires, shackles and jigs of the dimensions specified in the manual. They must be strong enough to support the mass of the machine. Check the mass of the machine by referring to the specifications in this manual. If the machine is hoisted using equipment that cannot bear its mass it will fall, causing serious injuries or damage to the machine. (3) Make sure that the machine is well balanced in both the crosswise and lengthwise directions after hoisting it a little above the floor. If you continue to hoist the machine although it is not properly balanced, it will fall, causing serious injuries or damage to the machine. (4) If two or more people work together to lift the machine, they must work carefully while exchanging signals. If someone operates the machine or the crane inadvertently when other people are working inside or close to the machine, it could cause serious injuries. (5) Before hoisting the machine, check that no tools, rags, etc., have been left inside it. When the machine is lifted, these articles could fall out and injure plant personnel or damage the machine. (6) If a crane is used to hoist the machine, do not carry the machine while it is lifted to an excessive height. Lifting the machine excessively high when carrying it will create more potential hazards than when carrying it at a lower height. (7) When moving the machine with a forklift, do not lift it high above the ground. If it is moved in this condition, it may become unbalanced and fall, or the forklift may topple over, causing serious injuries or damage to the machine. (8) Use a crane or forklift that can comfortably bear the mass of the machine. If a crane or forklift without sufficient capacity to lift the machine is used, the machine will fall, causing serious injuries or damage to the machine. (9) Lift the machine while it is supported at its center of gravity. If you select a point other than the center of gravity, it may become unbalanced and fall, causing serious injuries or damage to the machine.
CAUTION
(1) If a rust-preventive coating is applied to the slideway surfaces, it must be removed completely. Attempting axis feed while rust-preventive coating remains on the slideways could cause machine failure. (2) All transit clamps must be removed before switching the power ON. If a clamp cannot be removed without switching the power ON first, remove it immediately after switching the power ON. If axis feed is attempted while a clamp is still in place, the machine will be damaged. (3) Before hoisting the machine, check that all of its parts are clamped. Lifting the machine while any of the parts is not clamped adequately could damage the machine. (4) When installing the machine, mount the coolant tank and the chip bucket by pushing them into an appropriate position. Otherwise, coolant may be splashed around the machine causing the operator or persons around the machine to topple down and get injured.
NOTE
(1) When moving the machine with rollers, set the number of rollers, and the material that they are made of, so as to ensure that they can support the mass of the machine. Also use skid and leading boards that can support the mass of the machine. If they cannot support the mass of the machine the rollers, skid, or leading board may be distorted, making it impossible to move the machine. (2) After the machine has been installed, it must be leveled. Adjust the machine's crown and distortion values according to the Accuracy Test Results Chart delivered with the machine. If this adjustment is not carried out properly, machining accuracy will be adversely affected.
CONNECTING THE POWER CABLE This section explains the connection of power cable from the shop power distribution board to the transformer and then to the machine.
DANGER
(1) Power source work must be entrusted to an electrician with a license to carry out electrical work. If a person without knowledge of electrical safety practices attempts this work, he or she could be electrocuted. (2) Be sure to carry out the grounding work. If the grounding work is not done, there will be a danger of electrocution.
WARNING
Do not connect any other grounding wire to the ground. If a machine such as an electric welder or electric discharge machine is grounded to the steel reinforcing rods in the reinforced concrete structure of the plant, do not connect the grounding wire of the machine to the reinforcing rods too. Unless the grounding wire is connected to an independent ground, the machine could malfunction due to noise from other machines, leading to accidents involving serious injuries or damage to the machine.

Never connect the cable to wrong terminal blocks, otherwise the machine will be damaged. (2) If the cable is run through the punched hole in the transformer circuit breaker box, take proper cable protection means conforming to IP54.
NOTE
For the transformer of 24.5 kVA or 34.64 kVA, connect the power cable from L1, L2, and L3 to the primary side of the breaker. The transformers with larger capacity have terminal blocks, therefore, connection should be made to the terminal blocks.
5) Connect the ground cable to the terminal block PE in the transformer for grounding the machine. 6) Check the grounding resistance of the grounding wire. 7) Turn on the main breaker on the shop power distribution board.
8) Turn on the breaker of the transformer. 9) Check the input voltage. 10) Check the phase order with a phase rotation indicator. NOTE
If a phase rotation indicator is not available, check the phase order by checking the direction of rotation of the coolant pump motor.
WARNING
Check the overall phase order of the input voltages L1, L2, L3 (R, S, T) using a phase rotation indicator. If the phase order is incorrect, the machine will malfunction, causing serious injury or damage to the machine.
CONNECTION OF COMPRESSED AIR SUPPLY HOSE Follow the procedure below to connect the compressed air supply hose. 1) Turn off the power. 2) Connect the compressed air supply hose from the air source to the air supply port (Rc 3/8) in the air panel of the machine. 3) Start the compressor to supply the compressed air to the machine. 4) Make sure that there is no air leak at hose joints and pneumatic actuators. 5) Adjust the compressed air pressure to the specified value with the regulator in the air panel. For the correct air pressure, refer to page MACHINE SPECIFICATIONS in the MAINTENANCE INFORMATION published separately.
REMOVING TRANSIT CLAMPS After carrying the machine to the required place, remove all transit clamps before turning on the power. CAUTION
The transit clamps that cannot be removed before turning on the power should be removed immediately after turning on the power. Attempting axis feed while the transit clamps are in place will damage the machine.
Keep the removed transit clamps so that they will not be lost.
LEVEL ADJUSTMENT Carry out level adjustment to level the machine. CAUTION
After installing the machine, always check the machine level. If the machine level is not adjusted correctly, the machine will be tilted or twisted after installation. This will result in uneven wear of the bed and slideway surfaces and machining defects.
1) Place a level on the pallet or the table. 2) Loosen the lock nuts that fix the jack bolts. Spanner for lock nuts
Lock nut
3) Adjust the machine level by turning the jack bolts while observing the level. Spanner for jack bolts

CONSUMPTION VOLUME OF COMPRESSED AIR To operate the machine, it is necessary to supply the compressed air. Required volume of the compressed air varies depending on how frequently the ATC and/or APC is operated. The table below gives the units which use the compressed air and compressed air consumption volume in each operation of them. Use the values in the following table to estimate the total required compressed air volume to determine the capacity of the compressor. CAUTION
Select the compressor which can supply the required volume with sufficient margin. Otherwise, it will cause failure or damages of the machine.
