CNC tool is used in machining machinery for cutting tools, also known as cutting tools. Generalized cutting tools include both tools, including abrasive; the same time “CNC tool” in addition to cutting the blade, but also includes the tool holder and other accessories!
According to the tool structure can be divided into:
Integral: The tool is one piece, made from a blank, not separate;
Welding type: using welding methods to connect, sub-head and arbor;
Machine clip type: clip-type and can be divided into two kinds of indexable and indexable; usually CNC tool clip-on!
Special types: such as composite tools, shock-absorbing tools.
According to the material used to make the tool can be divided into:
High-speed steel cutting tools;
Carbide cutting tools;
Diamond cutter
Other material tools, such as cubic boron nitride knives, ceramic knives and so on.
From the cutting process can be divided into
Turning tools, sub-round, within the hole, thread, cut off, grooving and other tools;
Drilling tools, including drills, reamers, taps, etc.
Boring tools;
Milling tools
Hard coating

TiAlN, CrN, TiAlCrN is a new hard coating material developed in recent years. TiAlN coated blades have been commercialized. Its chemical stability and oxidation wear resistance, with its high alloy steel, stainless steel, titanium and nickel alloy tool life than TiN coating 3 to 4 times higher. In addition, TiAlN coating with a suitable aluminum concentration, when cutting tool rake and chip interface will produce a layer of hard inert protective film, the film has better thermal insulation can be more effective For high-speed cutting. For example, the Kennametal H7 blade is TiAlN-coated and is designed for high-speed milling of high-performance materials such as alloy steel, high-alloy steel and stainless steel. CrN is a titanium-free coating suitable for cutting titanium and titanium alloys, copper, aluminum and other soft materials with good chemical stability and no stickiness. TiAlCrN is a gradient structure coating, not only has high toughness and hardness, but also a small friction coefficient, suitable for milling cutter, hob, tap and other tools, cutting performance was significantly better than TiN.
Superhard tool material

Superhard tool material refers to the natural diamond hardness, similar to the performance of synthetic diamond and CBN (cubic boron nitride). Due to the high price of natural diamond, artificial polycrystalline diamond (PCD), polycrystalline cubic boron nitride (PCBN), and their composites are mostly used in the production.
