Woodworking lathe thimble always heating, and replaced the new did not use how long. Or so.
In the processing of small density of materials, should be in the processing process several times to Topstrong can. It is important to point out that if the center of the thimble is out of joint with the spindle of the lathe, the top front bearing will produce a larger radial force, which will cause the front bearing to wear faster and produce heat at the same time. At this point, should repair the lathe bed rail straightness and the bed two rail parallel degree. Only after the accuracy of the machine can be completely solved, only the new top can not solve the problem.
After the top is tight, the cutting resistance is caused by the work, so that the material at the top part of the force is squeezed and the gap between the top part and the top is prevented from being synchronized.
The thimble body heating is due to the damage of the thimble bearing, so it should be replaced. The top vertex heating is due to the rotation of the top and the material is not synchronized, the vertex movement between each other, resulting in friction heat.
