Mori Seiki CNC Vertical Machining Center CHK2-60/6

Is the orange mark visible on the knob?

If the knob cannot be turned, it is locked; pull the knob and the lock will be released.

If the knob cannot be locked easily, turn it slightly to the right and left and then press the knob again.

To set the required pressure, turn the knob CCW, passing the required position. Then turn it CW to set the required pressure.

Is the source pressure set to 0.5 MPa (71.1 psi)?

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

Spindle break-in operation performed at low speed (300 min-1) for 30 minutes?

Spindle break-in operation performed at high speed (1000 min-1) for 30 minutes?

Warning: If the spindle is rotated at a high speed without break-in operation, there is a possibility of spindle seizure.

Spindle cleaned using soft rags?

Warning: Never use compressed air to clean the spindle. If compressed air is applied between the spindle and the front cover, coolant will enter through the spindle bearings and extremely shorten the bearing life.

Spindle tapered hole kept clean?

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

Did the temperature of the spindle rise abnormally during operation?

1) Set the LVL at the "0" position.

2) Rotate the LVL in clockwise while the spindle is rotating at the spindle orientation speed.

3) Find the position where both the LVL1 and LVL2 LEDs are lit brightly.

If you rotate the LVL exceeding this point, the O-LVL LED will be lit.

The LVL should be set at the position where O-LVL LED is not lit.

NOTE: If the LEDs do not light in the order of LVL1 and LVL2, the magnet is mounted in the reverse direction. Therefore, change the magnet mounting direction.

1) Set the BIAS resistors (BIAS, M-BIAS, and L-BIAS) at the "5" position.

Warning: This maintenance check requires trained personnel with PPE!

Presence of dirt and water in the slideway lubrication unit tank

If dirt and water are present, proceed to clean the inside of the tank and the filter

Use washing oil to clean the filter

Filter cleaned with washing oil

Apply compressed air to the filter after cleaning

Compressed air applied to the filter

Do not use a thinner-based fluid to clean the filter

CAUTION: Follow the cautions on handling the lubricating oil.

(a) Store the lubricating oil where it will not be exposed to rain or direct sunlight.

(b) Prevent contact with dirt and water during storage.

(c) Never use degraded oils or oils that have been mixed with foreign matter during storage.

2) Oil jugs and intermediate tanks

(a) Never use the same oil jug for different lubricating oils and coolant.

(b) When an intermediate tank is used inside the factory building, relatively large amounts of dirt and water tend to accumulate at the bottom of the tank. Periodically inspect and clean the tank.
