The basic requirement is a fast cutting , and low- cost production of high quality products. This requirement is closely related to the realization of high-precision machining , high efficiency, low cost. In recent years, high-speed machining technology in milling, cutting fine shape with the rapid development of other fields . With the further miniaturization of the development and application of new engineering materials and components , precision , tool manufacturers are actively developing for a variety of processing and efficient tool .

In the automotive industry, as the center of manufacturing equipment investment and export growth traction , the demand for products, the growing tool , tool manufacturers have expanded production capacity at home and abroad . With the escalating costs of global competition , the user requirements to achieve high added value , high-efficiency production voice growing. In order to meet short delivery time , low -cost rapid production trends, the key is to use minimal equipment to achieve automatic operation processing time . Effective way to promote the rationalization of the production site is the introduction of multi-channel processes can be integrated composite cutting technology and enables high-speed , high-precision machining of hardened steel , including the workpiece material , including high-speed milling machines and other equipment.

Composite cutting , high-speed hard milling cutting technology and other advanced production equipment to achieve a minimum efficient, fast , flexible ( adapt to different species, different quantities of production ) core production of machined parts . However, any cutting mode are inseparable from the appropriate choice of cutting tools and tool to determine the reasonable use of technology . In recent years , with the increase machine speed , high-precision processing technology advances and cutting difficult materials , progress tool materials ( ceramics , carbide , TiC / TiN cermet coating carbide , etc. ) are also very significant.

Changing tool material
Tool material must meet the following criteria : high hardness , wear resistance, resistance to cutting with vibration resistance and high impact strength, good temperature red hardness, heat treatment and machining molding easy . In the tool material , the cemented carbide is characterized by little to reduce hardness at high temperatures. Wherein the coating is a tungsten carbide based cemented carbide substrate is coated on the surface layer or layers of titanium carbide (TiC), titanium nitride (TiN), aluminum oxide (Al2O3) and other film materials . Since the resistance of the frit coating material , abrasion resistance and heat resistance superior to the base , so they can be in excess of the substrate cutting speed cutting . In addition, due to the low coefficient of friction coating , so you can extend the life of the tool.

Requires the development of high-speed milling technology tool material with good abrasion resistance , heat resistance and toughness, so there is a lot of multi-layer film coating on ultrafine particles in order to improve the cutting carbide substrate coating Mills and other products. The average particle size of some of the ultrafine particles of 1μm or less carbide materials , toughness and flexural strength of the tool base body is significantly increased.

Composite coating is a combination of a variety of coating materials together, layer after layer multilayer thin film coating, in order to improve cutting performance . In addition to coating materials suitable for high-speed cutting steel titanium carbide and titanium nitride , and now also use diamond and cubic boron nitride. Recently, there has been coated with a nano- level fine grain silicon -based nano- coated tools , etc., can be used for high-performance processing of high-speed cutting of high hardness steel and mild steel .
