Although the names of many parts are very strange to us, we can’t deny that they really affect our lives. Take ina for example. Many people may not have heard of this term at all, but do you know? It is the main part of the machine tool during operation and plays a very important role in the stable operation of the machine tool.
The main feature of the component lies in its structure. Because its structure is simple, it is not difficult to manufacture, it is easy to produce, and it can bear large frontal and axial forces. As for its disadvantage, it can not bear radial force, so it needs to be used with the main shaft because the main shaft bears the radial load.
Compared with the above type, this type of ina roller slider not only has its main advantages, but also has a certain bearing capacity for radial load, and its guidance is also very excellent, but the disadvantage is that the manufacturing process is not convenient enough, and it is difficult to ensure the shaft surface and coaxiality in the manufacturing process. In addition, he can’t bear too much subversive torque.
The bearing force of this ina roller slider in radial force, axial force and overturning torque is obviously better than the two mentioned above. Accordingly, the manufacturing and grinding process is also very difficult, and coaxiality is difficult to ensure. And when the temperature of the two parts of the machine tool is different, the two ina roller slider surfaces are not easy to accept at the same time.
