August cutting machine tool output increased 8.8% year-on-year

In August, the output of China's metal-cutting machine tools increased by 8.8% year-on-year, which was the second only to February of this year, and it also increased by 6.9% from the previous month, reversing the two consecutive months of decline.

Affected by seasonal characteristics, August was the year-round low for machine tool sales. Some companies reported that orders fell within the range of 10% to 20%. However, the company also said that the degree of prosperity has no room for further downward growth. The time will remain stable, and it is expected that the growth rate of production will gradually increase on the basis of the original.

Metal-cutting machine tools are machine tools (except for hand-carried ones) that use cutting, grinding, or special machining methods to machine various metal workpieces to obtain the required geometry, dimensional accuracy, and surface quality. Metal-cutting machine tools are the most widely used and most numerous types of machine tools.

Metal cutting machine is a machine that processes metal blanks into machine parts by cutting. The process of metal cutting is the process of mutual movement and interaction between tools and workpieces. The relative motion of the tool and the workpiece can be divided into two aspects, one is the main movement and the other is the feed movement. The main movement that causes the workpiece and the tool to move relative to one another is the main movement. The speed of the main movement of the selected point on the blade with respect to the workpiece is called the cutting speed. The main sports feature is the highest speed and maximum power consumption.

The metal cutting process is performed by cutting the cutting layer of the workpiece by a tool. In the cutting process, the metal layer of the tool's cutting edge cut from the surface to be machined of the workpiece in one pass is called the cutting layer. The section size of the cutting layer is called the cutting layer parameter. In addition, there is an important concept to be introduced in the cutting layer - the backing blade ap. For cylindrical turning, it refers to the vertical distance between the machined surface and the surface to be machined.

With the continuous development of CNC machine tools and difficult-to-machine materials, tools are difficult to parry. To achieve high-speed cutting, dry cutting, hard cutting must have good tool materials. Among the many factors that affect the development of metal cutting, tool materials play a decisive role.
