Maintenance and Diagnostics
THC Slide Maintenance
Touchscreens, drops of water, and unintended motion
Drops of water can be a safety concern if the CNC is installed on an X-Y water table and the watch window is configured
with jog keys. If water splashes from the table onto the touchscreen, the drops can activate a jog key and create
unintended motion on the table. Unintended motion can result in danger to the operator and other people, damage to
machinery, or faults in cutting.
To prevent motion caused by drops of water on the touchscreen:
• Install the CNC so that the touchscreen is shielded from water splashes.
• If water could accidently hit the touchscreen, do not include the jog keys in the watch windows.
For additional information, contact your local Hypertherm Technical Service team.
THC Slide Maintenance
The ball screw in the lifter should be cleaned and lubricated every 6 months.
Cleaning
The ball screw should be cleaned carefully by wiping away all used grease, dust and dirt with a clean, dry cloth. If
possible, move the nut several times over the complete travel distance of the slide so that as much old grease as possible
comes out of the nut.
Note:
• Do not use any detergents or other cleaning fluids, such as trichloroethylene, alcohol, or acetone.
• Do not remove or disassemble the ball screw or ball screw nut.
Lubrication
To lubricate the lifter screw, apply a thin layer of fresh grease over the entire surface of the screw.
After lubrication, the assembly should be operated through its stroke several times at low speeds and low loads to ensure
that all the contact surfaces of the nut, balls, and screw are covered with a film of grease.
