Mori Seiki CNC Lathe DuraTurn 1530

NOTE! Refer to the steps 3) - 5) in "Replacing Oil" (page 2-346)

3) Remove the bolts beneath the tank and pull the hydraulic unit out from the base

7) Clean the suction strainer using the following procedure

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

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

Keep oil free from contamination

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

Clogged radiator causes oil pressure to be raised

Clogged suction strainer causes pumps and piping damage

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

NOTE! For oil types, refer to 'Oils' (page 2-324)

- Machine without External Chip Conveyor!

DANGER! Turn OFF the main power

b) Wait until the coolant level is stabilized after the coolant inside machine is returned to the coolant tank

c) Loosen the two jack bolts undernearth the tank after removing the hose and cables

d) Unlock the casters and pull the chip bucket outward

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

1. Replace the window at regular intervals (once every 5 years). Regardless of the replacement interval, stop using the machine and replace the window immediately in any of the following cases

• When damaged. [Workpiece, chips or coolant ejection/ Serious injury.]

• When cracked. (even it is slight) Because of its high degree of hardness, even an impact of a small chip may damage the entire window depending on its speed. Coolant may penetrate the window from the crack and accelerate the window degradation

• A very small initial fracture may spread across the window. This is the nature of the tempered grass, not a defect

• When hit with a strong impact. (EX. a workpiece disengaged from the chuck crashes into the window)

• Strength decreases extremely after having been subject to a strong impact even the appearance looks normal. Note that its safety can no longer guaranteed

• When visibility of the window cannot be secured and became difficult to grasp the conditions in the machining chamber. [Serious injury/Machine damage]

WARNING! Do not operate the chip conveyor or perform maintenance and inspections without reading and obtaining a thorough understanding of the contents of the chip conveyor instruction manual published separately. Keep the chip conveyor instruction manual on hand to enable immediate reference. Do not place hands or feet inside the chip conveyor during operation. [Entanglement of fingers and hands/Death or serious injury]

CAUTION! Do not operate the chip conveyor intermittently. [Malfunction such as tripping of the motor breaker (thermal relay)]. The chip conveyor cannot carry materials larger than cutting chips. [Chip conveyor damage]

Front door closed before operating the chip conveyor

No foreign matter on the chip conveyor belt

No excessive chip accumulation on the chip conveyor belt

No abnormal noise during operation

The chip conveyor cannot discharge all types of chips. Carefully consider appropriate cutting conditions to generate chips which can be removed from the machining chamber.
