PCD, PCBN forming tools, the spokesperson of the best auto parts processing solutions
In recent years, with the large number of lightweight materials used in the manufacture of automotive parts, the application of PCD and PCBN forming tools suitable for processing these materials has also increased significantly. For example, in the processing of gearbox housing, some processes change the original cemented carbide boring tool to diamond tool, so that the tool life is increased to tens of thousands of pieces, and significant economic benefits are obtained.
PCD tools are made by welding PCD composite pieces to a carbide or steel cutter body. The PCD composite sheet combines the high hardness, high strength, high wear resistance and low friction coefficient of single crystal diamond with the high flexural strength of tungsten carbide cemented carbide matrix, the tungsten carbide layer can provide mechanical support for the diamond layer and increase its bending strength, and at the same time, the cemented carbide layer is easy to weld, making the preparation of PCD forming tools easier.
High processing stability
When using PCD tools to process aluminum alloy workpieces, due to the high hardness of diamond, small affinity with metal materials, and most of the rake surfaces of the tools are polished into mirrors, it is not easy to produce built-up edge, and good machining dimensional stability and surface quality can be obtained.
The tool has a long service life
When using PCD tools to process aluminum alloy parts of various sizes and specifications, the tool life can reach thousands to tens of thousands of pieces, especially suitable for the large-scale production of automobile parts.
In terms of tool structure, PCD tools can be mainly divided into two categories: welded integral PCD forming tools and welded PCD blades.
Welded PCD forming tools with shanks (i.e., non-standard tools) are developing rapidly in the automobile and parts manufacturing industry, mainly including PCD forming milling cutters, PCD forming boring cutters, PCD forming reamers, and PCD composite forming tools composed of two or even three kinds of tools. The main forms of tool holders are cylindrical shank, BT shank (BT40, BT50), SK shank (SK40, SK50), HSK shank (HSK63, HSK100), etc. These forming tools can be used to process complex parts with high quality and efficiency in the first pass.
Welded PCD, PCBN inserts have the characteristics of flexibility, with the disposable tool, easy to cope with the engine block, cylinder head, transmission housing, valve body, groove, side cover and other parts of the complex process processing!
In addition, for the clamping of non-standard tool holders, we recommend hydraulic tool holders. In addition to high precision, short overhang, strong rigidity and convenient clamping, the hydraulic chuck also has one of the biggest features, a wide clamping range, and the maximum clamping size is 42mm, which can perfectly match the clamping of PCD non-standard straight shank tools!
