If the edge of one corner wears, the other corners will extend and replace the worn corners to continue cutting the workpiece. The main workpieces are large and medium-sized molds, auto parts and mechanical parts. The cutter head replaceable insert is also coated with a high-lubricity film "New JX Coating" for processing from soft non-ferrous metal materials to high hardness materials with a Rockwell hardness (HRC) of 60 and difficult to cut. Various materials for the material.
