To Next PageTo Next PageWhy is my Jet GH-1640ZK overheating?
If your Jet Lathe is overheating, it might be bogging down in the cut due to an excessive feed rate or depth of cut. Try decreasing the feed rate or depth of cut.
Why does my Jet GH-1640ZK have excessive machine vibration?
Excessive vibration in your Jet Lathe can stem from several issues: * An unbalanced workpiece. Try reducing the spindle speed. * Workpiece deflection. Adjust the chucking length or diameter, or use support on the tailstock end. * Tool deflection. Reduce the tool length. * Backlash on the slide ways/gibs. Adjust the backlash. * Dry slides. Properly lubricate the slides/ways. * A dull tool edge. Resharpen or replace the tool. * A high chip load. Reduce the depth of cut or feed rate. * Spindle bearings out of adjustment. Adjust the bearings. * Misaligned V-belts. Inspect and correct the belt alignment.
What to do if the tool tip burns on my Jet GH-1640ZK?
If the tool tip is burning on your Jet Lathe, consider these factors: * The cutting speed might be too high; reduce the speed. * The tool may be dull; resharpen or replace it.
Why does the spindle lack turning power or start up slowly on my Jet Lathe?
If the spindle on your Jet Lathe lacks turning power or starts up slowly, it could be due to slipping belts. Try tightening the belts.
Why does my Jet GH-1640ZK Lathe turn a taper?
If your Jet Lathe is turning a taper, it could be due to: * The tailstock not being aligned with the headstock. Align the tailstock. * The lathe bed being twisted. Correct this by leveling the lathe.
What to do if carriage, cross slide or compound rest move with difficulty on Jet GH-1640ZK Lathe?
If the carriage, cross slide, or compound rest on your Jet Lathe move with difficulty: * Ensure the carriage lock is released. * Adjust the gibs using the gib screws if they are too tight. * Clean the bed ways and verify they are being properly lubricated if they have shavings/debris or are dry.
Why is there no automatic power feed on my Jet GH-1640ZK?
If there is no automatic power feed on your Jet Lathe, the shear pin may be broken. Replace the shear pin.
