Characteristics of rotary center:

1. With certain waterproof performance, it is easy to dissipate heat as a whole;

2. It can inject oil regularly to prolong its service life;

3. The outer diameter is small and there are few interference cutters, which is more suitable for high-speed and moderate cutting work;

4. It adopts the inclined long needle roller bearing and the arrangement structure of three-point support, so that its rigidity is strengthened and its stability is good.

Features of fixed tip:

1. The front is equipped with a standard tungsten carbide center;

2. The top center and body can be used only after they have been precisely ground to meet the specified requirements;

3. The tungsten carbide core is made of SK2, and the hardness can reach 75hrc ± 2;

Disassembly and assembly method of rotary center and fixed center

In the process of using the rotary center, if the center has problems and needs to be disassembled, the first thing is to find the bearing cap on the rotary center. Some people may not know where the bearing cap is. The part with two small holes in the head is the top cap. Then, insert a tool into the small hole and rotate it gently so that the bearing and cap can be taken out. Then, remove the screws at the back of the taper sleeve end. Then, use a tool to push the bearing out of the top shell from the rear. After replacing the deep groove bearing and thrust bearing, it is finished. Just reverse the order when assembling.

There are some small differences between the top, so we should be cautious in the selection and use of the top. Be careful when replacing the inner bearing of the center.
