An inverter alarm on your Jesco Lathe (VS-model) can be triggered by several issues: Operation error (switch off for 20 seconds and switch on again as reset). Wrong set of parameter. Circuit not complete (check the power source and reconnect properly). Footbrake switch keep in touch (re-positioning the switch and tighten it). Inverter problems.
What causes incorrect spindle speed on my Jesco PRINCE?
Incorrect spindle speed on your Jesco Lathe can be caused by several factors: Voltage below what is rated (check the power source voltage). Connecting cable too small (enlarge the connecting cable). Improper or loose connection of lead (recheck all leads connecting). Failure on spindle select knob (replace it). Overload (reduce cutting speed and depth or feed rate).
How to resolve bending on long workpiece cutting with my Jesco Lathe?
Bending during long workpiece cutting on your Jesco Lathe can occur if the feed value is too large (reduce the feed value). It can also happen if the workpiece is too thin or too long (use a follow rest to support it and adjust the tool position).
Why is my Jesco Lathe motor noisy and vibrating?
If your Jesco Lathe's motor is noisy and vibrating, consider the following potential causes: The motor is loosely mounted (tighten the mounting bolts). The mounting frame is strained (stiffen the mounting place or add shims under the foot pad). The motor shaft is bent or sprung (straighten or replace it). The foundation is inadequate or the motor feet are uneven (shim the motor feet for equal mounting).
What to do if my Jesco PRINCE Lathe fails to start?
If your Jesco Lathe fails to start, check the following: The circuit might not be complete (check the switch, leads, fuse, etc., and replace or reconnect properly). The power may be off (check the cable connection). The overload relay may be off (reset the overload relay).
Why is my Jesco Lathe coolant pump failing?
A failing coolant pump on your Jesco Lathe could be due to several reasons: Wrong rotation (reverse any two leads to the pump). Not enough coolant or a return filter obstructed (replenish coolant or clean the return filter in the chip tray). Overload relay off (reset the overload relay).
Why is my Jesco PRINCE leaking oil?
Oil leakage in your Jesco Lathe could be due to several reasons: The plug of the drain isn't tight (reseal and tighten it). The case is cracking (it needs to be repaired by special welding). There's leakage from the overflow (tighten the cover screws). The packing or gasket is damaged (replace the packing or gasket). Or there's leakage from the overflow on the spindle bearing housing (reduce oil flow to the bearing or enlarge oil return flow).
What to do if my Jesco PRINCE motor is overheating?
If your Jesco Lathe motor is overheating, consider these potential causes: Excess belt tension (adjust the belt tension). A cooling fan failure (check the fan for proper operation). A badly worn bearing (replace the bearing). Short grease in bearing (replenish grease). Overload (reduce cutting speed or feed rate). Incorrect speed range running continuously (change the speed range and adjust the speed select knob).
