​Characteristics of CNC toolholder types:
1) When machining curved parts, in order to ensure that the cutting edge of the tool is tangent to the machining contour at the cutting point and avoid interference between the cutting edge and the workpiece contour, a ball-end cutter is generally used, a two-edge milling cutter is used for rough machining, and a four-edge milling cutter is used for semi-finishing and finishing.
2) When milling a larger plane, in order to improve production efficiency and improve the roughness of the machining surface, a blade-embedded disc milling cutter is generally used.
3) When milling a small plane or step surface, a general milling cutter is generally used.
4) When milling a keyway, in order to ensure the dimensional accuracy of the slot, a two-edge keyway milling cutter is generally used.
5) When machining holes, drills and other hole machining tools can be used.
The structure of tool holders for CNC machine tools is divided into two types: integral and modular. The integral tool holder has a working part that clamps the tool and a handle that is used to install and position the tool on the machine tool. This type of tool holder has poor adaptability to the changes of machine tools and parts. In order to adapt to the changes of parts and machine tools, users must reserve tool holders of various specifications, so the utilization rate of tool holders is low.
The modular tool system is a more advanced tool system, and each tool holder can be assembled through various serialized modules. According to different processing parts and machine tools, different assembly schemes can be adopted to obtain a variety of tool holder series, thereby improving the adaptability and utilization rate of tool holders.
