8.3. Lathe

This machine serves for turning between centres and face turning and is suited for chucking work. Construction


Figure 21 Lathe

The machine bed made of cast iron carries the headstock, tailstock, hand rest and spindle drive. The electric motor for the spindle drive is located in the left base. Tailstock and rest are adjusted along the bed by hand and arrested by an eccentric. The gap makes machining of short workpieces with large diameter possible.

Information on labour safety

Chucks with protecting chuck jaws, clamp or locking screws are to be provided with a smooth all-round cover. Never leave the key in the chuck. Do not check the workpieces while they are rotating. Do not remove the chips while the machine is running. Do not slow down workpieces by hand during the run-out. The hand rest should be as close to the workpiece as possible. Do not lay down tools on the machine bed. Wear tightly fitting clothing.

Recommendations for maintenance

Slightly grease all bare parts regularly with acid-free grease. Regularly check the function of the cam-lock. Keep the machine bed clean. Make sure that the tailstock is in perfect condition. Clean the faceplate, chuck and tailstock centre regularly from adhering dirt, resin and similar.
