Features of CNC lathe

1、High machining accuracy
CNC machine tools are given in digital form by the instructions for processing. At present, the pulse equivalent of CNC machine tools generally reach 0.001, and the feed drive chain backlash and screw pitch error can be compensated by the CNC device, therefore, CNC machine tools can achieve high machining accuracy. For small and medium-sized CNC machine tools, its positioning accuracy is generally up to 0.03, repeatable positioning accuracy of 0.01.


2, strong adaptability to the processing object
CNC machine tools to change the processing of parts, only to reprogramming, input new programs Guo can achieve the processing of new parts, which is a complex structure of single-piece, small batch production and trial production of new products provides great convenience. For those ordinary manual operation of ordinary machine tools are difficult to process or can not be processed precision and complex parts, CNC machine tools can also realize automatic processing.
3, high degree of automation and low labor intensity
The processing of parts is automatically completed according to the pre-programmed program, the operator in addition to placing the perforated belt or operating the keyboard, loading and unloading of workpieces, intermediate testing of key processes and observation of the machine tool operation, there is no need for complex repetitive manual operation. CNC machine tools generally have better safety protection, automatic chip removal, automatic cooling and automatic lubrication devices, the operator’s labor conditions greatly improved.
4, high production efficiency
CNC machine tool spindle speed and feed a wide range of changes, so CNC machine tools can be selected for each process the most favorable cutting amount. CNC machine tools have good structural rigidity, allowing a large amount of cutting power cutting, improving cutting efficiency, saving the maneuvering time. Because the CNC machine tool moving parts of the empty stroke movement speed, so the workpiece clamping time, auxiliary time is less than the general machine tool.
5, convenient replacement of machined parts
CNC machine tools to replace the machined parts almost do not need to re-adjust the machine tool. Therefore, saving parts installation and adjustment time. CNC machine tool machining quality is stable, generally only do the first piece of inspection and sampling inspection of key dimensions between processes, therefore saving downtime inspection time. When machining on a machining center when a machine tool to achieve a multi-process continuous processing, the improvement of productivity is more obvious.
6, good economic benefits
① the use of CNC machine tools, can save marking hours, reduce the adjustment, processing and inspection time, saving direct production costs; ② processing parts generally do not need to make special fixtures, saving the cost of process equipment. ③ CNC machining accuracy and stability, reducing the scrap rate, so that the production cost is further reduced. ④ can realize a machine multi-purpose, save plant area, save investment in plant construction.
