Description

Technical Field

[0001] The utility model relates to the technical field of guide wheels, in particular to a durable machine tool guide wheel. Background Art

[0002] The 404 wire cutting machine needs to use a guide wheel to realize the return rotation of the diamond wire. Since the diamond wire is in direct contact with the guide wheel, the guide wheel will inevitably be worn during use. After a period of use, replacement of the guide wheel due to wear is inevitable; although silicon nitride ceramics have excellent hardness and wear resistance, the cost of guide wheels made of silicon nitride ceramics is too high, so most guide wheels made of tungsten steel are used. Tungsten steel has slightly poor wear resistance, so it wears frequently, resulting in a high replacement frequency and increased maintenance burden; and the existing machine tool guide wheels are usually an integrated structure, so as long as the guide wheel is partially worn, it needs to be replaced, which increases the cost of use.
