Cutter grinding machine

Abstract

The invention discloses a cutter grinding machine comprises a support. Grinding wheels are arranged on the support through a driving shaft, and the driving shaft is connected with a driving device. The cutter grinding machine is characterized in that the support is provided with a grinding wheel truing device, and the grinding wheel truing device is arranged above the grinding wheels. Because theworn grinding wheels can be trued frequently at any time by the grinding wheel truing device, the cutter grinding efficiency and the service lives of the grinding wheels can be obviously improved andprolonged, and accordingly the cutter grinding efficiency and the service lives of the cutter grinding machine which uses the grinding wheels rather than steel wheels can be also obviously improved and prolonged. Moreover, the trued grinding wheels have smooth surface and obviously improved cutter grinding precision.

Description

technical field [0001] The invention relates to a knife grinder, in particular to a knife grinder which uses power to drive a grinding wheel to rotate at a high speed to grind the blade of a thread trimmer. Background technique [0002] The grinding wheel of the knife grinder that grinds the blade of the thread trimmer will wear to a certain extent after working for a period of time. The worn grinding wheel will affect the machining accuracy of the tool, so it needs to be corrected frequently. In the past, the sharpening machine used the steel wheel as the grinding wheel. After the steel wheel was worn, it had to be removed to correct it, and it could not be corrected frequently. The surface of the wheel is relatively rough, and the machining accuracy is not high; while the traditional grinding wheel sharpener is usually not equipped with a grinding wheel correction device, and the grinding wheel still needs to be removed before it can be corrected after it is worn, which wi...

In the past, the sharpening machine used the steel wheel as the grinding wheel. After the steel wheel was worn, it had to be removed to correct it, and it could not be corrected frequently. The surface of the wheel is relatively rough, and the processing accuracy is not high; while the traditional grinding wheel sharpener is usually not equipped with a grinding wheel correction device, after the grinding wheel is worn, it still needs to be removed before it can be corrected, so it will have a certain impact on the processing efficiency
