Technical Field
[0001] This utility model belongs to the field of grinding technology, specifically relating to a precision rotary grinding machine. Background Technology
[0002] A grinding machine is a machine tool that uses abrasive wheels to grind the surface of a workpiece. Most grinding machines use high-speed rotating grinding wheels for grinding, while a few use other abrasive wheels and free abrasives, such as honing machines, ultra-precision machining tools, belt grinders, lapping machines, and polishing machines. Grinding machines can process materials with high hardness, such as hardened steel and cemented carbide, as well as brittle materials, such as glass and granite. Grinding machines can perform high-precision grinding with very low surface roughness, and can also perform high-efficiency grinding, such as heavy-duty grinding.
[0003] Existing grinding machines can only adjust the position of the grinding disc within a certain range, which makes it impossible to fully grind the surface of the material. It is necessary to repeatedly remove the material to adjust the position, which is inconvenient to use. Therefore, we propose a precision rotary grinding machine. Utility Model Content
