1. Highly flexible
Machining parts on a CNC lathe mainly depends on the processing procedure. Unlike ordinary lathes, it does not need to be manufactured, many molds and fixtures need to be replaced, and the lathe does not need to be re-adjusted frequently. Therefore, the CNC lathe is suitable for the occasions where the processed parts are frequently replaced, that is, it is suitable for the production of single-piece, small-batch products and the development of new products, thereby shortening the production preparation cycle and saving a lot of process equipment costs.
2. High processing accuracy
The machining accuracy of CNC lathes can generally reach 0.05-0.1MM. CNC lathes are controlled in the form of digital signals. Every time the CNC device outputs a pulse signal, the moving parts of the lathe move a pulse equivalent (usually 0.001MM), and the lathe The average error of the backlash of the transmission chain and the screw pitch can be compensated by the numerical control device. Therefore, the positioning accuracy of the numerical control lathe is relatively high.
3. The processing quality is stable and reliable
To process the same batch of parts, on the same lathe, under the same processing conditions, using the same tools and processing procedures, the cutting paths of the tools are exactly the same, the consistency of the parts is good, and the quality is stable.
4. High productivity
The CNC lathe can effectively reduce the processing time and auxiliary time of the parts. The range of the spindle sound speed and feed rate of the CNC lathe is large, which allows the lathe to perform powerful cutting with a large amount of cutting. CNC lathes are entering the era of high-speed machining. The rapid movement and positioning of moving parts of CNC lathes and high-speed cutting have greatly improved productivity. In addition, it can be used in conjunction with the tool magazine of the machining center to realize the continuous processing of multiple procedures on a lathe, which reduces the turnaround time between procedures for semi-finished products and improves productivity.
5. Improve working conditions
After the CNC lathe is adjusted before processing, input the program and start it, and the lathe can automatically and continuously perform processing until the end of the processing. What the operator has to do is program input, editing, parts loading and unloading, tool preparation, machining status observation, and parts inspection. The labor intensity is greatly reduced, and the labor of the lathe operator tends to be intellectual work. In addition, lathes are generally combined, which is both clean and safe.
6. Utilize production management modernization
CNC lathe processing can accurately estimate the processing time in advance, standardize and modernize the tools and fixtures used, and easily realize the standardization of processing information. It has been organically combined with computer-aided design and manufacturing (CAD/CAM). It is the foundation of modern integrated manufacturing technology.
