Co to jest?

CNC (Computer Numerical Control) broaching machines are highly automate tools that execute broaching operations undeir precise programe control. Broaching itself is a machinng process that uses a toothed tool, called a broach, to remove material in a single pass. The broach has a serie of cutting teeth that presige in height alongh thee tool, aling eacproviing tooth to take a progressivele deeper cut until thee fintail desired shape.

There are several type of broaching operations, each phased to specific geometries:
