Machine tools are machines that process metal blank into machine parts. They are machines that manufacture machines, so they are called “workhorse models” or “tooling machines”, traditionally referred to as machine tools. There are many methods of processing machine parts in modern machinery, which include casting, forging, welding, stamping, and extrusion, etc., except cutting. Machine parts that require high precision and fine roughness of the surface are finally processed by cutting through machine tools
Counters can record the number of mechanical movements of machine tools and have reference value on maintenance and lifetime of machine tools.
