High processing accuracy

CNC machine tools are processed according to instructions given in digital form. At present, the pulse equivalent of CNC machine tools has generally reached 0.001, and the backlash of the feed transmission chain and the lead screw pitch error can be compensated by the CNC device. Therefore, the CNC machine tool can achieve high machining accuracy. For medium and small CNC machine tools, the positioning accuracy is generally up to 0.03, and the repeat positioning accuracy is 0.01.

Strong adaptability to processing objects

When changing the machining parts on the CNC machine tool, you only need to reprogram the program and input the new program. Guo can realize the processing of the new parts. This provides great opportunities for single-piece, small-batch production and trial-manufacture of new products with complex structures. convenient. For those precision and complex parts that are difficult or impossible to be processed by ordinary manual machine tools, CNC machine tools can also realize automatic processing.

High degree of automation, low labor intensity

The processing of the parts is automatically completed according to the pre-programmed program. The operator does not need to perform complex and repetitive manual operations except for placing the punched tape or operating keyboard, loading and unloading the workpiece, intermediate inspection of key processes and observing the operation of the machine tool. . CNC machine tools generally have better safety protection, automatic chip removal, automatic cooling and automatic lubrication devices, and the operator's working conditions have been greatly improved.

high productivity

The spindle speed and feed rate of the CNC machine tool have a wide range of changes, so each process of the CNC machine tool can choose a favorable cutting amount. The CNC machine tool has good structural rigidity, which allows powerful cutting with a large amount of cutting, which improves cutting efficiency and saves maneuvering time. Because the moving parts of the CNC machine tool have a fast idle stroke movement speed, the clamping time and auxiliary time of the workpiece are less than that of the general machine tool.
