To Next PageTo Next PageWhy does my Grizzly Lathe workpiece slip in chuck?
If the workpiece slips in the chuck of your Grizzly Lathe, it may be because the chuck jaws don't match the workpiece diameter (reposition or mold the workpiece to match the jaw dimensions), the cutting force is too high (reduce it), the speed is too high (reduce spindle speed), or the jaws are worn (replace jaws or chuck).
Why Grizzly Lathe carriage will not feed or is hard to move?
If the carriage on your Grizzly Lathe won't feed or is hard to move, it could be due to several reasons: the gears are not all engaged (engage gears using gear dials); the half nut lever is engaged (disengage it); the screw is loose on the feed handle (tighten it); the carriage lock is tightened down (release it); chips have loaded up on the ways (clean them frequently); the ways are dry and need lubrication (lubricate bedways/ball oilers); the gibs are too tight (loosen gib screw(s) slightly); gears or a shear pin are broken (replace them); or the feed clutch is slipping (increase clutch spring pressure).
Why Grizzly Lathe machine does not start or a circuit breaker trips?
The Grizzly Lathe might fail to start or trip a circuit breaker due to several reasons: the emergency stop button may be depressed or faulty (rotate to reset or replace); the main power switch could be OFF or defective (turn ON or replace); the OFF button might not be reset (press until it clicks); the plug/receptacle may be faulty or wired incorrectly (test contacts, correct wiring); the power supply voltage or circuit size could be incorrect (ensure correct voltage and size); the circuit breaker may be tripped or fuse blown (reset breaker or replace fuse after ensuring correct sizing and no shorts); motor wires could be connected incorrectly (correct wiring); wiring may be open or have high resistance (check/fix broken, disconnected, or corroded wires); the start capacitor might be fault...
Why does my Grizzly Lathe motor stall or is underpowered?
The motor on your Grizzly Lathe might stall or seem underpowered because the machine is undersized for the task. To resolve this, use sharp tools at the correct angle, reduce the feed rate and depth of cut, and use coolant if possible. Other potential causes include: * Feed rate/cutting speed too fast (decrease it). * Wrong workpiece material (use the correct type/size of metal). * Belts slipping (tension/replace belts and ensure pulleys are aligned). * Motor wired incorrectly (correct the wiring). * Plug/receptacle at fault (test for good contacts/correct wiring). * Gearbox at fault (select appropriate gear ratio; replace broken or slipping gears). * Motor overheated (clean motor, let cool, and reduce workload). * Run capacitor at fault (test/repair/replace). * Pulley/s...
What to do if Grizzly Lathe has vibration or noisy operation?
If your Grizzly Lathe is vibrating or operating noisily, check the following: * Motor or component loose (inspect/replace damaged bolts/nuts, and retighten with thread locking fluid). * Bit chattering (replace/sharpen bit; index bit to workpiece; use correct feed rate and cutting RPM; retract tool holder and position workpiece closer). * V-belt(s) worn or loose (inspect/replace belts with a new matched set). * Motor fan rubbing on fan cover (fix/replace fan cover; replace loose/damaged fan). * Motor mount loose/broken (tighten/replace). * Pulley loose (re-align/replace shaft, pulley set screw, and key). * Machine incorrectly mounted (tighten mounting bolts; relocate/shim machine). * Motor bearings at fault (test by rotating shaft; rotational grinding/loose shaft requires b...
