PREVENTIVE MAINTENANCE
The press has been designed to minimize maintenance as much as possible. The following preventive
maintenance procedures should be done on the intervals given below. An annual inspection, adjustment, and
calibration service is offered by TE.
DANGER
Always turn off the main power switch and disconnect the electrical cord from the power source when performing maintenance
on the press.
Accessing the Press Head (CBP)
To gain access to the CBP press head for inspection or service, open the front or rear door in the top hood.
Actuate the latch to open the hood, front or rear. To gain access to the CMP press head, remove the front
cover panel.
Cleaning
All surfaces should be kept clean and free of dust buildup. Wipe down all exposed flat surfaces with a soft rag.
If allowed in the facility, use light air pressure to blow the press head and structure areas from the top down.
Inspection
Visually inspect the press head area. The top sheet metal housing or front cover panel should be removed
once per year to allow a thorough inspection. See Section 12.1 for procedure to remove top housing.
Whenever the top sheet metal housing is removed (CBP) or the rear electrical cabinet is opened (CMP), the
main power surge protect
or should be checked. The surge protector is located far left of the panel’s DIN rail.
With the machine energized, verify that the green LED on the surge protector is illuminated. If not, it is likely the
machine has been exposed to one extreme voltage surge or several significant surges, such as might be
generated by nearby lightning strikes to the power lines supplying the facility.
If the LED is not illuminated, the machine will still operate but is no longer protected from potentially destructive
power line events. Replace the surge protector to restore protection.
Light Curtain Interlock
The Light Curtain is the primary operator safety device. When the light curtain senses an obstruction, the EMO
circuit is de-energized, and motion is halted. To insure safe operation, the light curtain requires periodic checks.
Refer to the Light Curtain’s user manual for instructions on performing the periodic test using the supplied test
wand for proper and safe operation.
Lubricating
Light machine oil or 30W non-detergent motor oil should be used in the following areas of the machine:
Z Axis Rods
With the Z axis in the down position, put a small amount of oil on the rods above each of the linear guide
bushings. Grease linear bushings thru grease fittings.
Z Axis Screw
With the Z axis in the down position, put a small amount of oil on the screw and wipe down with a rag.
There should only be a thin coating of oil remaining. Grease thru grease fitting on nut.
Torqueing Critical Bolts
NOTE
This procedure requires the top sheet metal housing to be removed on CBP (see Section 12.1 for procedure details). The
critical bolts on the pressing head should be checked for proper torque. The Z axis bearing housing is a 50 mm 1.97 in.] thick
block, mounted to the top of two upright plates with 6 M10 x 1.5 socket head bolts. Torque bolts to 90 Nm [66.4 lbft].
