Principle of CNC lathe

The CNC lathe uses the camshaft rolling to drive the tool drilling, while the CNC lathe uses the programming to control the tool posture with the system. In terms of the output power, the active lathe is much better than the CNC lathe, and the processing cost of the lathe will be cheaper than the CNC lathe. If the commodity is more complex and the requirements are high, the active lathe may not be able to do it, and only rely on the CNC lathe to do it, However, its processing cost needs to be higher than that of the active lathe. For a product, we still choose to use the active lathe for production and processing. The most important thing is still the difficulty of the commodity.

CNC lathe

The manufacturing process of CNC lathe is similar to that of general lathe, but since the lathe is clamped at one time and the milling process is completed continuously and actively, we should pay attention to the following aspects. Select the right tool for durability: for high-power metal cutting, the three major factors are the processing of raw materials, the drilling of objects, and the drilling prerequisites. This determines the timing of production and processing, the life of CNC blade and production quality. The valuable production and processing method for economic development is to select appropriate drilling standards.


The three elements of drilling requirements: cutting amount, cutting speed and cutting depth immediately cause the hazard of CNC blade. With the advance of cutting amount, the ambient temperature of the cutting edge will rise, and mechanical, chemical reaction and thermal damage will occur. If the cutting amount is increased by 20%, the service life of the CNC blade will be reduced by 1/2, and the connection between the feed standard and the damage behind the CNC blade will occur in a small range. However, the cutting speed is high, the cutting temperature is high, and the rear wear is large. It has less influence on the CNC tool than the cutting amount. The influence of cutting depth on the CNC blade is not as large as the cutting amount and cutting speed, but the hard bottom layer of the cut raw material will also endanger the life of the CNC blade when the micro-cutting drilling is performed.


The customer shall select the cutting amount to be used according to the raw material, strength, drilling condition, material type, cutting speed, cutting depth, etc. to be produced and processed. The selection of suitable production and processing requirements for CNC vertical lathe is specified under the premise of various factors. Choosing a CNC vertical lathe manufacturer is an ideal prerequisite for regular and stable damage to reach the service life. However, in the specific operation, the selection of the life of the CNC blade is related to the life of the tool, the modification of the size to be produced and processed, the surface quality, the drilling noise, the production and processing heat, etc. After the production conditions, the demand will be analyzed according to the specific situation.
