Metal cutting tools are important tools in cutting. Commonly used are high speed steel (such as W18Cr4V, W6Mo5Cr4V2), powder high speed steel, coated high speed steel (such as PVD coating), fine grain and coated hard alloy (such as adding TaC, NbC YG type), composite ceramics (such as Si3N4 ba.......
Carbide reamer is an important tool for semi-finishing or finishing holes. The speed of the reaming can be several times to ten times higher than that of the high speed reamer, the surface roughness can reach Ra1.6~0.4, the precision is 0-7, and the durability is 3~10 higher than the high spee.......
In the past, the material returning devices we used on the punching machines were generally dedicated to the special model, and some of the structures were complicated and the volume was large. To this end, I made a simple material return device, which is described as follows: 1. Structure pri.......
Among the parts produced by our factory, there is a part as shown in Figure 1. If the special broach is the same as the non-full-shaped spline shape on the part, it not only complicates the design of the broach and the broach chuck, but also does not distribute the cutting area on the same bla.......
"Bearing iron" is one of the key parts of our factory to produce a certain product. The material is 10 steel copper plating, and the shape and size of the parts are shown in Figure 1. It can be seen from Fig. 1 that the shape of the part is not complicated. As a thin disc, eight stra.......
In metal cutting, cutting fluids are often used. The main function of the cutting fluid is to reduce the cutting temperature and improve the friction and wear state of the machining process, thereby improving the surface quality of the workpiece and prolonging the service life of the tool. How.......
As is known, ordinary hobbing machines can only process involute spur or helical gears and cannot process involute bevel gears. The main reason is that the ordinary hobbing machine hob cannot be fed radially relative to the workpiece, or the radial feed and axial feed of the hob cannot be perf.......
Since entering the era of mobile Internet, global smart enterprises have entered the cycle of innovation acceler.......
The processing of high-precision annular thin-walled parts has always been a problem in machining. In the manufacture of aero-engines, there are many processing of annular thin-walled parts. The solution to the processing methods of this type of parts reflects the level of mechanical manufactu.......
Programmable controller is a new type of industrial control device developed by microprocessor as the core, integrated computer technology, automatic control technology and communication technology. It combines the advantages of both traditional relay control technology and modern computer inf.......
The living room is a common area of ​​the living room and an important part of the living room, so the choice of floor tiles is very important.
First, the specifications of polished .......
