CNC turning has high precision and stable quality
In addition to manual loading and unloading, the whole processing process is automatically completed by the machine tool when machining parts on the CNC lathe, which completely avoids manual operation error. At the same time, CNCturning has good dimensional consistency for the same batch of parts, high product qualification rate and stable processing quality.
Because the CNC machine tool is processed by digital instructions, the pulse equivalent of the current CNC device is generally up to 0.001 mm, and the feed transmission chain is short, its reverse clearance and screw pitch error can be compensated by the NC device, so that the CNC turning can achieve higher machining accuracy. In addition, the corresponding feed speed can be set according to different cutting surfaces during CNC turning programming, so that when machining different curvature surfaces, the tangential feed speed of the cutter along the contour is basically unchanged, so as to further ensure the accuracy and surface roughness of the machined surface.
High productivity of CNC turning
The reason for the high productivity of CNC turning is that the machining process effectively reduces the machine time and auxiliary time. In CNC turning, more surfaces can be machined in one clamping. Through programming, the continuous machining of parts such as rough machining, semi finish machining and finish machining can be completed in turn, which can effectively reduce the time required for multiple clamping and semi-finished product turnover, significantly reduce the motor time and improve the productivity. The high movement speed and wide range of rotation speed and feed rate of CNC turning make it possible to choose the most favorable cutting parameters for each process, so as to save the motor time, and its rapid movement also reduces the idle travel time. Because the CNC turning process only uses a simple positioning and clamping device, when replacing parts, it only needs to replace the program, and there is no need to further adjust the machine tool. When the cutting tool is in good condition, after the first trial cutting, it is often only necessary to spot check the key dimensions between processes, so as to further improve the utilization rate of CNC lathe.
High degree of automation in CNC turning
When CNC turning parts, in addition to the manual loading and unloading of the workpiece, the first piece of tool setting, and the intermediate measurement of key processes, all the processing processes are completed automatically according to the pre programmed program, which avoids the repetitive manual operation of the operator, greatly reduces the labor intensity of the operator, and improves the working conditions.
CNC turning adapts to the change of machining object rapidly
When the processing object changes, there is no need to remanufacture and replace many tools and fixtures, let alone readjust the lathe. Only by re programming a new part processing program, it can quickly change from one part processing to another part processing, thus providing the most favorable conditions for the improvement, modification and replacement of products, and the research and development of new products.
