The heat pipe tool is a self-cooled tools, it can greatly reduce the cutting temperature (the thermal conductivity of the heat pipes than the equivalent silver, Tongbang hundreds of times higher), improve the cooling effect from the outside, so no further pouring the cutting fluid, particularly suitable in CNC machine tools, abrasive wheel,machining centers and automatic production line.
The tool cooling channel design is also a high-speed processing tool structure design. Will generate a lot of heat due to high-speed processing, and the heat resistance of the tool material is limited, so the use of high-pressure coolant and the channel to the cutting area, the cutting region of the cooling and lubrication of the tool through the tool for the fluid (oil), to improve tool effective ways of life and their reliability. In recent years, the tool with internal coolant for liquid (oil) channel from the extended to ordinary shallow hole drilling, deep hole machining tool reamers and endmills products.velcro disc
Seco tool launched replaceable carbide drill head (head, there are three drill-type: the head of the P-type grades suitable for cutting steel, The K type suitable for cutting cast iron and aluminum parts, M-type suitable for processing high-strength steel and corrosion-resistant steel). Japan used TiN coated carbide single-blade reamer (cutting speed up to 150-400m/min), they are within the cooling fluid supply hole getting smaller and smaller, and specifications. According to reports, Japan's Mitsubishi special craft with the MZS Carbide small drill hole diameter as small as 3-4.5mm hole diameter of 0.4-0.6mm. Even if cutting the poor condition of the cutting knife, also using this cooling method. For liquid through the machine spindle or toolholder.
The tool management innovation is the main direction of the tool management outsourcing. Since the the tool management outsourcing model development in foreign sixties and seventies of the 20th century, domestic from Shanghai General Motors in 1998, the application of this concept, continuous company to start applications, such as Shanghai Volkswagen gearbox, SAIC-GM-Wuling engine project, PBR Dalian , project SAIC Rover and Qingdao SAIC-GM-Wuling engine projects. It is understood that Beijing Huatai engine project, Dalian Volkswagen gearbox project also being actively explored the tool management outsourcing. From the effect of the falling cost of tool management to analyze the short term, the outsourcing model and manage their own tool may be little difference between the effect may even be lower than their own management. However, the long term effect of the decline in the cost of outsourcing model tool is much much better, abrasive tools,due to the decline in the cost of the tool management outsourcing model is directly driven by the interests, their performance is directly related to the decline in the cost of the tool management and the various resources of the company will be mainly to support the achievement of the goals of the tool management costs decline. They will try to obtain the maximum effect of the decline in the cost of the tool management.grinding wheel
