Five basic methods of the hottest metal machining

Five basic methods of metal machining

1 drilling

there are many types and sizes of machine tools. The types of modern machine tools are almost unlimited. Some machine tools are so small that they can be installed on the workbench, while others are so large that a special workshop can be built to accommodate them. Some machine tools are quite simple, while the structure and operation of some machine tools are very complex

whether machine tools are large or small, simple or complex, they can be divided into five categories, which are the five basic methods for metal forming. The first three months of 2017 may be the lightest quarterly method in more than 310 years

drilling is the processing of drilling holes in solid metal. A rotary drill called a fried dough twist drill is used. The machine tool used for drilling is called a drilling machine. There are also many types and specifications of drilling machines. In addition to drilling, the drilling machine can also carry out other processing. When drilling, the workpiece is positioned, clamped and fixed; The drill bit rotates while drilling into the workpiece (see Figure 1)

2 turning and boring

ordinary machine tools are the most common machine tools for turning workpieces. Turning is the process of cutting metal from the workpiece. While the workpiece rotates, the tool cuts into the workpiece or turns along the workpiece (see Figure 2)

Figure 2 turning

boring is a processing method to expand or further process the drilled or cast holes on the metal workpiece. Boring on the lathe is completed by rotating one side of the single edge tool and feeding the workpiece (see Figure 3)

3 milling

milling is the processing of cutting metal with a rotating tool. This tool has multiple cutting edges, which is called a milling cutter (see Figure 4)

4 grinding

grinding is a processing method that uses a grinding wheel called a grinding wheel to cut metal. Grinding is used to finish the workpiece, and the machined workpiece has accurate size and smooth surface. When grinding a circular workpiece, one side of the workpiece rotates and the other side feeds towards the rotating grinding wheel. When grinding a flat workpiece, the workpiece moves back and forth under the rotating grinding wheel (see Figure 5). Grinding technology is often used for the final finishing of hard workpiece after heat treatment to make it reach the precise size

5 ox head planing, gantry planing and slotting machine slotting

these processes all use single edge tools to produce precise planes. We should know the difference between shaper, planer and slotter. When machining with a shaper, the workpiece is fed to the cutter, and the cutter moves back and forth on the workpiece (see Figure 6)

when machining with a gantry plane, the tool cuts into the workpiece or feeds into the workpiece, and the workpiece moves back and forth under the tool (see Figure 7)

inserting a low-temperature groove is a cutting process similar to ox head planer in terms of impact testing machine

the slotting machine is actually a vertical shaper, but its cutting tool moves up and down. For slotting machining, take the spring on the vehicle for example. The workpiece, such as the direction of the tool, has made a given movement. According to the type of workpiece being processed, sometimes it is linear, sometimes it is arc (see Figure 8). The slotting machine is a vertical shaper, which is mainly used to cut some types of gears

broaching machines can be classified as gantry planers. Broach has multiple teeth. Broaching machine can be used for internal processing, such as processing square holes, or external processing, processing planes or a specific shape. (end)
