How to use different kinds of live centers

Live Center is a very important machine tool component in mechanical processing. It has a large demand and a wide range of applications.

Let me introduce you some different types, uses and maintenance matters.

Live Centers, machine tool parts in machining, are available in Dead Center or revolving live center. The lathe is used to center and bear the gravity and cutting force of the workpiece. Front center of lathe The front center can be directly installed in the taper hole of the spindle of the lathe. The front center and the workpiece rotate together without relative movement, so there is no need to quench.

Top features of the revolving live center:

1. Small outer diameter and less interference knives, suitable for high speed and moderate cutting;

2. Regular oil injection can prolong the service life.

3. It has a certain waterproof function, and the whole is easy to dissipate heat;

4. The use of long-pitch needle roller bearings, three-point support arrangement structure rigidity and good stability.

Features of Dead Centers:

1. Front-mounted standard tungsten carbide core;

2. The core material of tungsten carbide is SK2, the hardness reaches 75HRC±2;

3. Both the top and the body need to be precision ground to meet the requirements.

For the processing and production process of the machine tool, it is very common to have some minor defects. Although some minor defects will not cause much impact on the entire production and processing, but if they occur throughout the production process, their work efficiency may appear to be damaged, turning the top For the machine tool, it plays a very important role in the processing of the workpiece, and the rotary center can be rotated, and then the center is inserted to make the machine run more smoothly. At the same time, if the rotary center is used in the machine, it can solve or directly avoid some unnecessary problems.
