The surface grinder spindle temperature will rise rapidly after a long time of operation. The temperature between 60 ℃ and 70 ℃ is within the normal range. If it is too hot to touch, the spindle is out of order.
The causes of surface grinder spindle sugar are as follows:
1. The lubricating oil layer of the spindle bearing of the surface grinder is polished, so the sharp metal friction will produce a lot of heat.
2. The feed amount of grinding wheel of surface grinder is too large, which has exceeded the bearing lubricating oil film's bearing range, resulting in dry friction.
3. The scraping contact between the main shaft and bearing bush is poor, and the rolling bearing assembly is too tight.
The summary of the above small series, hope to help you.
