7-7 Brake and Micro Switch Adjustment
Foot brake is linked to Micro Switch. It needs
to maintain a backlash of 3-5mm from Brake
Cam to the touching head of the Micro Switch.
Always disconnect the power to break the
machine or it will cause the fading of brake pad.
After stepping the foot brake, needs to reiterate
the spindle control lever to make the spindle
revolute again.
7-8 Adjustments to the Backlash of Lead screw
When it happens to some pile-up threads during processing, it is caused by the
backlash on Lead screw. Adjust the packing nut appropriately on rear side of the Lead
screw. Open the cover on rear side of Lead screw Bracket, turn nut “A” very tight
with no backlash left behind. (To check the result by pushing down Half Nut Handle,
turn Apron Hand-wheel to rotate, clasp the contact point between Gear Box and Lead
screw. Make sure there is no backlash created). Install “A” nut and side cover.
7-9 Maintenance for Cutting Liquid Coolant Pump
If there is no cutting liquid flow out when you start the motor switch, you have to
check whether motor has activated or not, secondly to check whether the cutting
liquid in tank is over the level, if not, needs to add more liquid. While re-starting the
pump if you still can not see any liquid were pumped out, it must be some block-up in
pump or leakage, and it has to be taken apart for servicing or cleaning.
