In actual production, metals are the most common processing materials, but for different metals and different processing requirements, the processing methods adopted are also different. Below we will introduce specifically, the production of more commonly used five metal processing methods, so that we have a certain understanding of this.
There are many machine tools of different sizes. The types of modern machine tools are almost infinite. Some machine tools are so small that they can be installed on the worktable, and some machine tools are so large that they need to build special factories to accommodate them.
Some machine tools are quite simple, while some machine tools are very complex in construction and operation. Whether machine tools are large or small, simple or complex, they can be divided into five categories, which are the five basic methods to make metal forming.
Drilling is the processing of drilling holes on solid metal. Use a rotary drill called a twist drill. Machine tools used for drilling are called drilling machines. Drilling machine also has a variety of models and specifications. In addition to drilling, drilling machine can also carry out other processing. When drilling, the position of the workpiece is clamped and fixed; the bit rotates rotated and drilled into the workpiece on one side.
2.Turning and boring
Ordinary machine tools are the most common machine tools for turning workpieces. Turning is the processing of removing metal from the workpiece. While the workpiece rotates, the tool cuts into the workpiece or turns along the workpiece.
Boring is a method of expanding or further processing holes that have been drilled or cast from metal workpieces. Boring on a lathe is done by rotating one side of a single-edge tool towards the workpiece.
Milling is the use of rotating tools to remove metal processing, this tool has multiple cutting blades, called milling cutters.
Grinding is the process of cutting metal using a grinding wheel called a grinding wheel. The workpiece is finished by grinding. The workpiece is accurate in size and smooth in surface. When grinding circular workpiece, one side of the workpiece rotation, one side of the rotating grinding wheel feed. When grinding a flat workpiece, the workpiece moves back and forth under a rotating grinding wheel. The grinding process is often used to finish a hard work piece after heat treatment to an exact size.
5.Bullhead planer, gantry planer and insert machine
All of these processes use single-edge tool machining to produce precise planes. We should understand the difference between the head planer, the gantry planer and the insert. When machining with oxhead planer, the workpiece is fed to the cutter, and the cutter moves back and forth on the workpiece.
When machining with a gantry planer, the tool cuts into the workpiece or feeds to the workpiece, and the workpiece moves back and forth under the tool.
Slotting is similar to planing.
Slotting machine is actually a vertical shaper, except that its cutting tools move up and down. In slotting, the workpiece moves in the direction of the cutter, sometimes in a straight line and sometimes in an ARC, depending on the type of the workpiece being machined. A vertical shaper used primarily for cutting certain types of gears.
Broaching machines fall into the category of double housing planers. The broach has a plurality of cutter teeth. Broaching machines can be used for internal machining, such as square holes, or external machining, machining surfaces or specific shapes.
