Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a numerical control machine tool which is convenient for tool adjustment. Background Art

[0002] CNC machine tool is the abbreviation of digitally controlled machine tool. It is an automated machine tool equipped with a program control system. The basic components of CNC machine tools include processing program carrier, CNC device, servo drive device, machine tool body and other auxiliary devices.

[0003] The working principle of a CNC machine tool is to drive a high-speed rotating tool mounted on a set program to move and cut the workpiece. In existing technologies, the tool is mounted on the drive mechanism via a tool holder. Some also use a turret-type tool changer to allow the tool to be rotated, adjusted, and replaced. However, the existing turret-type tool changer is not stable after rotation and is prone to loosening. To address this issue, we propose a CNC machine tool that facilitates tool adjustment.
