What are the advantages of CNC machine tools compared with traditional machine tools?

Compared with traditional machine tools, CNC machine tools have the following advantages:

1. It is highly flexible

In the CNC machine tool processing parts, mainly depends on the processing program, it is different from ordinary machine tools, do not have to manufacture, replace many molds, fixtures, do not need to often re-adjust the machine tool.Therefore, the CNC machine tool is suitable for the processing of parts frequently replaced occasions, that is, suitable for single, small batch product production and development of new products, thereby shortening the production preparation cycle, save a lot of process equipment costs.

2, high machining accuracy

Machining accuracy of nc machine tool can reach 0.05 0.1 MM, nc machine tools is according to the form of digital signal control, numerical control device every output a pulse signal, the machine moving parts move a pulse equivalent (0.001 MM), and machine tool feed drive chain of the reverse clearance and screw pitch error of the mean by the nc device march compensation, therefore, the numerical control machine tool positioning accuracy is higher.

3, the processing quality is stable and reliable

Processing the same batch of parts, in the same machine tool, under the same processing conditions, using the same tool and processing procedures, the tool path is exactly the same, the consistency of the parts is good, quality stability.

4. High productivity

CNC machine tool can effectively reduce the processing time and auxiliary time of parts, CNC machine tool spindle speed and feed range is large, allowing the machine tool to carry on the strong cutting of large cutting quantity.CNC machine tool is entering the era of high speed machining, CNC machine tool moving parts of the rapid movement and positioning and high speed cutting processing, greatly improve productivity.In addition, combined with the tool library of machining center, it can realize the continuous processing of multiple processes on one machine tool, reduce the turnover time between processes of semi-finished products, and improve productivity.

5. Improve working conditions

CNC machine tool processing is adjusted before, the input program and start, the machine can have automatic continuous processing, until the end of processing.The operator to do is the input of the program, edit, parts loading and unloading, tool preparation, processing state observation, parts inspection and other work, labor intensity is greatly reduced, the labor of the machine tool operator tends to intellectual work.In addition, machine tools are generally combined, both clean and safe.

6, the use of production management modernization

The processing of numerical control machine tool, can estimate the processing time accurately in advance, can carry on the standardization to the tool that uses, the fixture, can carry on the modernization management, is easy to realize the standardization of the processing information, has been combined with the computer aided design and the manufacture (CAD/CAM) organically, is the foundation of the modernization integration manufacturing technology.
