  • What is dimensional chain

    There are two characteristics of the dimensional chain: closedness-each size of the dimensional chain constitutes a closed system in a certain order; correlation-one of the size changes will affect other size changes.

  • Skills Of Using U Drill On CNC Machine Tool

    Compared with the integral drill, the U-drill is a tool that performs hole machining by combining a center blade (inner edge) and an outer periphery blade (outer edge). This structure determines that the U-drill has an irreplaceable advantage over other drilling tools.

  • CNC Machine Coordinate System

    In the process of writing a CNC machining program, in order to determine the relative position of the tool and the workpiece, the movement path of the tool must be described through the machine tool reference point and the coordinate system.
