Mori Seiki CNC Vertical Machining Center MSD-680

Warning: Ensure the power is turned off and the compressed air supply is shut off before starting the procedure.

Compressed air supply shut off?

Turn the case assembly (1) 45 degrees while pressing the lock button down.

Case assembly turned 45 degrees?

Loosen the baffle (2). The element (3) can be taken out of the case assembly.

Baffle loosened and element taken out?

Wash the element (3) using neutral detergent.

Element washed with neutral detergent?

NOTE: Zero return adjustment (from obtaining the reference point to setting parameters) should be carried out for each axis.

Set zero point setting parameters. Refer to manual prepared by CNC maker.

For the axis for which the zero point is to be set, obtain the reference point in the manner explained in 2.1, 'Obtaining the Reference Point'.

Carry out zero return operation.

Adjust the position of the dog so that the position data will be as indicated.

After the axis enters the range indicated above, note the current position display data. Then, reset the position display to '0'.

Turn the pulse handle to find the position where the zero return deceleration switch (SQ1 for X-axis, SQ2 for Y-axis, SQ3 for Z-axis) changes from the ON state to the OFF state.

Feed the axis by turning the pulse handle in the negative direction until the zero return deceleration switch state changes from '1' to '0'. After that, feed the axis in the zero return direction by turning the pulse handle to find the position where the zero return deceleration switch state changes from '0' to '1'.

At the position where the zero return deceleration switch state changes from '0' to '1', display the position display screen to check the position data.

Warning: This procedure requires trained personnel with PPE!

Enter the internal pressure inside the case

Is the valve 2 closing the slot in the chamber 3?

Is the piston 4 forced down due to spring 5 force?

Is the foreign matter entering the drain housing through the slot 3 in the chamber?

When pressure is applied, does the piston 4 move up, overcoming the spring 5 force, to come into contact with the O-ring 6, enclosing the inside of case 7?

When foreign matter accumulates inside the case, does the float 1 rise from buoyancy to open the slot in the chamber 3?

CAUTION: Follow the cautions when starting spindle rotation and cleaning the spindle.

Enter the low speed spindle rotation (min-1)

Enter the high speed spindle rotation (min-1)

Did you perform the break-in operation at low and high speed for 30 minutes each?

When cleaning the spindle, use soft rags to wipe off coolant, dust, and other foreign matter.

Did you use compressed air to clean the spindle?

Keep the spindle tapered hole clean. Foreign matter adhering on the tapered hole surface will deteriorate spindle accuracy or preclude tool clamping collet operation.

Is the spindle tapered hole clean?

If the temperature of the spindle rises abnormally during operation or abnormal noise is generated, contact Mori Seiki as soon as possible.

DANGER: Before carrying out oil cooler inspection and maintenance, always turn OFF the power supply.

Check if the machine is not operating before replenishing oil.

Check if the oil used is clean and as specified.

Check if the tank, oil strainer, and other parts are clean.

Check if there is a large volume of dust and dirt accumulated on the condenser.

Check if the air filter is cleaned every two weeks with an air gun.
