How to maintain an ordinary lathe without cutting?

In the hub on the west side of the lathe, the gear on the automatic feed shaft is separated from the gear on the output shaft on the spindle hub, resulting in no feed on the lathe. Don't turn on the machine tool, turn the shaft of the tool manually, and look forward in the first gear. Where it doesn't turn, the problem lies.

Ordinary lathe is a horizontal lathe, which can process various types of workpieces such as shafts, disks and rings with various technologies. It is often used for machining internal and external revolving surfaces, end faces and various internal and external threads of workpieces. With corresponding tools and accessories, it can also be used for drilling, reaming, tapping and knurling. Ordinary lathe is one of the most widely used lathes, accounting for about 65% of the total number of lathes. Because its spindle is placed horizontally, it is called a horizontal lathe.
