Mori Seiki CNC Turning Center NL3000MC/1250

DANGER: Turn OFF the main power before performing maintenance work

CAUTION: If the oil level decreases rapidly, the pump unit or the machine may be malfunctioning. Contact the Mori Seiki Service Department for assistance.

CAUTION: Maintain oil at the correct level to prevent air being suctioned through the pump unit.

CAUTION: Keep oil free from contamination.

CAUTION: If foreign matter accumulates in the tank, oil cannot be kept free from contamination, causing pump damage.

CAUTION: Clogged radiator causes oil pressure to be raised.

CAUTION: Clogged suction strainer causes pumps and piping damage.

CAUTION: If the oil pressure setting is incorrect, hydraulic unit malfunction and damage may result.

For oil types, refer to “OILS” (page 59).

WARNING: Ensure that the power is turned OFF when performing maintenance.

Oil pan placed beneath the drain plug

Drain plug removed and all oil drained from the tank

Sealing tape wrapped around the threaded part of the plug

DANGER: Turn OFF the main power and disconnect the plant-side power supply (breaker).

CAUTION: 1. Do not use compressed air. [Machine failure due to chips and coolant entry]

2. To maintain machining accuracy, clean the machining chamber after completion of machining operations.

3. Do not touch chips without protective gloves. [Injuries]

Cleaning Slideway (Ball Screw) Protective Covers and Operator Door Rail

Clean off chips that have accumulated on the protective covers, e.g. with a broom.

Cleaning Cylinder Rear Section (Hollow Chuck Specifications)

WARNING: Do not operate the high pressure coolant unit or perform maintenance and inspections without reading and obtaining a thorough understanding of the contents of the operation manual provided with the high pressure coolant unit.

Keep the high pressure coolant unit operation manual on hand to enable immediate reference.

After the completion of the maintenance and inspections, remount all covers before running the machine.

Main power turned OFF before removing the rear cover?

V-belt checked for wear, damage and looseness?

V-belt tension adjusted if necessary?

Drain tube placed in a drain pan?

Oil in the tank drained by slowly opening the drain plug?

DANGER: Prior to opening the electrical cabinet door, take care to ensure the plant-side power supply (circuit breaker) is turned OFF. Even when the main switch on the electrical cabinet is turned OFF, parts in the cabinet may still hold residual current resulting in an electric shock if touched accidentally.

CAUTION: If foreign matter adheres to the fan, it impairs cooling performance. Clean the fan periodically.

Disconnect the plant-side power supply (breaker)

Open the electrical cabinet door

Remove the screws A and remove the fan body with the securing board

NOTE: Do not remove the screws B first. Otherwise, the fan body will fall.

Remove the screws B and remove the fan guard
