Machine tools are very popular in today's industries. Typically, they are used to make metal components of machines by machining. It is a mechanical device. It plays a rather important role in the industries. Many places use the machine tools to generate power.

Single-screw machine is a very important category. They can be widely seen in our industries. Of course, the structure of these machines is also very necessary for us to learn. Among all the different structures, the structure of machine tool spindle catches people's eyes.

At present, there are two available single-screw machine spindle structure of the program in the country. The first one is the spindle structure with a bearing radial clearance which is not adjustable. There are one pairs of cylindrical roller bearings and thrust ball bearing combination before this kind structure. The former is used to bear the radial cutting force, while the latter is applied to bear the axial thrust cutting force. After the principal axis, there are always one pairs of cylindrical roller bearings or a ball bearing to the heart.

Of course, every coin has two sides. Mechanical products are all the same. This kind of structure has both advantages and disadvantages. The main advantage is that the processing and assembly of the main axis is simple as well as cheap. Compared to the advantages, there are more disadvantages. One is that the precision of the spindle is poor for that the main axis of the radial bearing clearance can not be adjusted. The other is that this kind of structure is not suitable for the spindle of machine tools which require a higher accuracy although it can be used in the general machine tools with general accuracy.

The second category is the spindle structure with an adjustable bearing radial clearance. There are some difference between the first category and the second one. Before this structure, There are spindle bearing P4 class of double row tapered hole cylindrical roller bearings and a P4-class double row ball bearing thrust to the combination of heart. And the former is used to bear the radial cutting force, while the latter is applied to bear axial cutting force and part of radial cutting force.

Like the first one, this kind of structure also has advantages as well as disadvantages. According to the above analysis, we may predict that one advantage is that the precision of the spindle is quite high. And complicated process is one of its disadvantages.
