Exploring the secrets of CNC machining centers: Why has it become a powerful tool in modern manufact

The development of CNC machine tools is changing with each passing day. High speed, high precision, compound, intelligent, open, parallel drive, networking and green have become the trend and direction of CNC machine tool development. From small screws and mechanical parts to large weapons, aerospace, medical equipment, automobiles, ships, airplanes, railways, from primary product processing to high-precision and high-tech product manufacturing parts, they are inseparable from the high-speed operation of high-precision, high-efficiency and "flexible" automated production equipment in the factory - CNC machine tools.

CNC machining advantages

1. High production efficiency:

Production capacity can generally be increased by 3 to 5 times.

(1) CNC machine tools can effectively save maneuvering time, quickly move to shorten the idle stroke time, and have a wide range of feed amounts. They can effectively select reasonable cutting amounts.

(2) Multiple processes can be completed in one clamping, eliminating the need for multiple changes in work types and transfers between processes, and the time for part installation and adjustment is short.

(3) Simplified fixtures and special tooling, because the processing is completed in one clamping. The multi-process fixture process of ordinary machine tools is eliminated. Even if special fixtures must be used occasionally, the structure of the fixtures can be simplified due to the functions of CNC machine tools.

2. High machining accuracy:

(1) The machine tool structure has high rigidity and thermal stability, and measures are taken to reduce errors. Errors can also be compensated by CNC devices, so CNC machine tools can achieve high machining accuracy. The positioning accuracy can generally reach 0.01mm, and the repeat positioning accuracy is 0.005mm.

(2) The transmission system of CNC machine tools uses gapless ball screws, rolling guides, zero-gap gear mechanisms, etc., which greatly improves the transmission stiffness, transmission accuracy and repeatability of machine tools.

(3) CNC machine tools are automatic processing, eliminating human errors, improving the consistency of processing dimensions of parts in the same batch, and stable processing quality. One installation can perform uninterrupted processing of multiple processes, reducing installation errors.

(4) The error compensation function of the CNC system eliminates system errors.

3. Automation:

The CNC lathe processing process is automatically completed according to the input program. The operator only needs to start tool setting, loading and unloading workpieces, and changing tools. During the processing process, the main task is to observe and supervise the operation of the machine tool.

4. High flexibility:

By changing the program of the CNC machine tool, new parts can be processed on the CNC machine tool, and it can be operated automatically, with good flexibility, high efficiency and long service life, so it can adapt well to market competition.

5. Strong adaptability:

(1) When processing a new workpiece on a CNC machine tool, it only needs to re-compile the processing program of the new workpiece to realize the processing of the new workpiece.

(2) When processing a workpiece on a CNC machine tool, only a simple fixture is needed, and there is no need to make batches of tooling fixtures, and there is no need to repeatedly adjust the machine tool. Therefore, it is particularly suitable for single-piece, small-batch and trial-produced new product workpiece processing, realizing automated processing.

6. Conducive to the modernization of production management:

The use of CNC machine tools can accurately calculate the single working hours of a product and arrange production reasonably. CNC machine tools use digital information and standard codes to process and control processing, creating conditions for realizing the automation of the production process. And effectively simplify the information transmission between inspection, fixtures and semi-finished products.

7. Good economic benefits

(1) Using CNC machine tools for processing can save working hours, reduce adjustment, processing and inspection time, and save direct production costs.

(2) Processing parts generally does not require the production of special fixtures, saving process equipment costs.

(3) CNC processing has stable accuracy, reduces the scrap rate, and further reduces production costs.

(4) It can realize multiple uses of one machine, save factory area, and save factory construction investment.
