Description

technical field

[0001] The invention relates to a friction drive device, which belongs to the technical field of friction processing. Background technique

[0002] In the precision machining of granite, it is necessary to use a friction head to grind the surface of the granite. The existing friction drive device is provided with only one friction head, and the grinding efficiency is low. Moreover, there is no distinction between rough grinding and fine grinding, which is inconvenient to use. Contents of the invention

[0003] The purpose of the present invention is to overcome the problem that the existing friction driving device only has one friction head, the grinding efficiency is low, and there is no distinction between rough grinding and fine grinding, which makes it inconvenient to use. The friction drive device of the present invention is provided with a coarse friction wheel and a fine friction wheel, which can realize two divisions of labor and graded grinding, an...
