Trumpf Laser Cutting Machine Trumatic L3030

Warning: This maintenance check requires trained personnel with PPE!

In hostile operating conditions, change lubricant more frequently.

Grease packed bearings cleaned and regreased?

Input (high speed) bearings should not be over greased. They should be filled with grease not to exceed 1/3 of the bearing’s free volume.

For output bearings and bearings with replacement grease shields, fill to 2/3 of their free volume.

Do not mix lubricants of different brands. Do not mix synthetic lubricants with one another or with one having mineral base.

Checked alignment, belt tension and mounting bolt torque?

CAUTION: ALWAYS DISCONNECT POWER TO CONVEYOR BEFORE ATTEMPTING ANY MAINTENANCE PROCEDURES.

Install belt as stated in Parts and Service Manual, except do not tension belt.

Tighten pillow block bearing bolts, and then loosen five (5) 1⁄4 turns.

Set torque wrench to 25 inch pounds.

Manually rotate belt back and forth.

Repeat steps (3) and (4) until belt rotation no longer results in decreased torque setting.

Run machine for (2) hour break-in period.

Loosen adjusting bolt locknuts. Loosen bearing bolts as noted in step (2). Repeat steps (3), (4) and (5).

NOTE: Belts with discharge heights in excess of 50” or load length in excess of 8 ft. may require higher torque settings.

Position belt with a link pin directly below the conveyor drive shaft.

Hold a straightedge across the bottom of the conveyor discharge at the very rear.

Measure vertically from the straightedge up to the underside of the belt.

Push up on the underside of the belt.

Repeat the measurement from the straightedge up to the underside of the belt.

Is the measurement in step 5 approximately 1/16 inch (1.5mm) greater than the measurement in step 3?
