Cutting tool according to the form on the surface of the workpiece processing can be divided into five categories. Processing of the surface cutting tools, including turning, planing tool, milling cutter, broach and outside surface file, etc.; Hole processing tool, including drilling, reaming, drilling, boring cutter, reamer, and pull a knife on the inner surface, etc.; Thread machining tools, including the opening and closing tap, die, automatic thread cutting head, thread turning tool and cutter, etc; Gear cutting tools, including gear hob, pinion cutter, shaving cutter, bevel gear cutting tools, etc; Cutting knives, including tipped circular saw blade, band saw, bow saw, saw blade milling cutter and cutting tool and so on. In addition, there are combination tool.
       Press cutting movement mode and the corresponding shape of the blade, cutting tool and can be divided into three categories. General tool, such as turning, planing tool, milling cutter (not including the cutting tool of the forming, the forming cutter and forming milling cutter), boring cutter, drill bits, reamer drill, reamer, and saws, etc.; Cutter blade forming cutter, which have a section of the same or nearly the same with the machining shape, such as forming tool, forming cutter, forming milling cutter, broach, conic reamer and all kinds of thread cutting tools, etc.; Generative cutting tools is to use generating method processing gear tooth surfaces or similar artifacts, such as gear hob, pinion cutter, shaving cutter, bevel gear cutter and bevel gear milling cutter, etc.
Cutting tool materials are the following categories: high speed steel, cemented carbide, ceramics, metal ceramics, polycrystalline cubic boron nitride and polycrystalline diamond.
       I mainly to ceramics, ceramics for earlier than cemented carbide cutting tools, but due to its brittleness, development is slow. But since the 1970 s, and obtained fast development. Ceramic cutting tool materials mainly has two department, namely, aluminum oxide and silicon nitride. Ceramic as a cutting tool with low cost, high hardness, high temperature resistant performance is good wait for an advantage, have very good prospects.
      YingMing for cutting tool, the current domestic foreign product difference is very big, the cutting tool is a high technology goods!
With YW series of best, 2 knife, open the coarse rake Angle of the bit Angle after 3 ~ 6 degrees can be ten degrees or so. Fine car top Angle points in 10 to 15 degrees hind can also corresponding big 3 ~ 5 degrees or so this roughness better answer people added 2009-05-15 17:29 rough machining blade Angle is 0 degrees can doesn't matter but finishing necessarily is 10 to 15 degrees, so your workpiece surface roughness is better, the direction of the blade Angle of main control chip is the chip removal of negative outward to the workpiece away, easy to scratch the workpiece
