The most feared problems with lathes are tool collisions, overcutting and poor raw material work surfaces.

How to avoid tool collision?

1. The centring problem of the toolpost. If the toolpost is too long or used for a long time, its clearance may increase, which will easily cause the tool to shake and thus collide. Therefore, the aging toolholder should be replaced in time.

2. Loose problem of tool and workpiece. If the tool is not fixed firmly or the workpiece is loose, it is easy to cause tool collision, so special attention should be paid to the machining process.

3. Choose the right tool. If the tool used is not suitable, it is easy to cause collision, so it is very important to choose the right tool.

How to prevent tool overcutting?

Overcutting refers to the state of cutting edge missing or damaged due to too deep cutting and too much tool load. Overcutting is often caused by improperly set machining parameters, such as too fast a feed rate or too deep a depth of cut. In order to prevent overcutting, it is necessary to set the machining parameters according to the different machining objects.

Pay attention to the firmness of the outside of the workpiece.

Only the work surface is firm, to ensure that the workpiece cutting will not be affected by the cutting force and produce swing. If the working surface is not firm, it will cause the workpiece to sway, resulting in a loss of precision. Therefore, when clamping the workpiece in the chuck, attention should be paid to its firmness to avoid wobbling and other situations.
