Introduction To The Characteristics And Structural Forms Of Tool Handles

The rigidity, accuracy, durability and dynamic balance performance of the tool are more strictly required in NC machining. Tool selection should pay attention to the structure and process analysis of the workpiece, combined with the processing ability of CNC machine tools, workpiece materials and process content and other factors. The material of Cnc Tool Holder is generally 40Cr. The commonly used tool holders in NC machining are mainly divided into drilling TOOL HOLDER, boring Tool Holder, milling tool holder, threaded tool holder and straight handle tool holder. Titanium Hao Machinery Co., Ltd. should be selected for the purchase of NC tool holders, with professional quality and quality assurance. The company has passed the ISO 9001:2000 international quality management system certification, can provide users with various kinds of machine tool accessories in accordance with national standards, German standards, American standards, Japanese standards and other different standards, to meet the different needs of customers.

Type characteristics of NC tool holder:

1) When machining curved surface parts, in order to ensure that the cutting edge of the tool is tangent to the machining outline at the cutting point and avoid interference between the cutting edge and the workpiece outline, ball-end cutters are generally used, two-edge milling cutters are used for rough machining, and four-edge milling cutters for semi-finishing and finishing.

2) In order to improve production efficiency and surface roughness, insert disc milling cutter is usually used when milling larger plane.

3) General milling cutter is usually used when milling small plane or step surface.

4) When milling keyway, in order to ensure the dimensional accuracy of keyway, two-edge keyway milling cutter is usually used.

5) When processing holes, drills and other hole processing tools can be used.

The structure of tool holder of NC machine tool:

1. The structure of tool holder of NC machine tools can be divided into two types: integral mode and modular mode. The working part of the clamping tool of the integral tool holder is integrated with the handle used for fixing and positioning on the machine tool. This kind of tool holder has poor adaptability to the transformation of machine tools and parts. In order to adapt to the transformation of parts and machine tools, users must store various specifications of tool holders, so the utilization rate of tool holders is low.

2. Modular tool system is an advanced tool system. Each tool handle can be assembled by a series of modules. For different parts and machine tools, different assembly schemes can be adopted to obtain a variety of tool shank series, thus improving the adaptability and utilization of tool shank.
