Hardware Tool Knowledge: Main Tools Category

The tool can be divided into five categories according to the form of the workpiece surface. Tool for machining a variety of outer surfaces, including turning tools, planers, milling cutters, broaches, boring tools, etc.; hole-cutting tools, including drills, reamers, boring tools, reamers, and broaches on the inside; thread machining Tools, including taps, dies, automatic opening and closing threads, thread turning tools, thread milling cutters, etc.; gear cutting tools, including hobs, pinions, shavers, bevel gears, etc.; cutting tools, including inserts Circular saw blades, band saws, hack saws, cutting tools, saw cutters, etc. In addition, there are combination cutters.

According to the cutting movement mode and the corresponding blade shape, the tool can be divided into three categories. General-purpose tools, such as turning tools, planers, milling tools (not including shaped turning tools, shaping planers, and forming cutters), boring tools, drills, reamers, reamers, saws, etc. Forming tools, cutting edges of such tools It has the same or nearly the same shape as the cross-section of the workpiece to be machined, such as forming lathes, forming planers, forming cutters, broaches, conical reamers, and various thread cutting tools, etc.; Teeth or similar workpieces, such as hobs, pinions, shavers, bevel gears, bevel gear cutters, etc.

Tool materials are roughly classified into the following categories: high-speed steels, carbides, cermets, ceramics, polycrystalline cubic boron nitride, and polycrystalline diamond.

I mainly mention ceramics, ceramics used in cutting tools than cemented carbide, but due to its brittle, the development is very slow. However, since the 1970s, the development has been relatively fast. There are two major ceramic cutting tool materials, namely alumina and silicon nitride. Ceramics as a cutting tool have the advantages of low cost, high hardness, good high temperature resistance, and have good prospects.

The name should be the cutting tool. At present, the domestic and foreign products are very different. The tool is a high-tech consumer product!

With YW series, the best, 2 knives, open rough corners 3 to 6 degrees can be about 10 degrees. The front corner of the fine car 10-15 degrees after the big foot can also be about 3 to 5 degrees larger, so the roughness is good to answer people's supplementary 2009-05-15 17:29 cutting edge inclination is generally 0 degrees can be indifferent but fine Processing must be positive 10-15 degrees, so that your workpiece surface roughness is a good point, the cutting edge of the main direction of chip control chip evacuation of the positive direction of the outward go to the workpiece, easy to scratch the workpiece.
