The impact of CNC lathe machining accuracy is generally caused by the following reasons, one is the equipment reasons, the second is the tool problem, the third is programming, the fourth is the reference error, today and you briefly describe these aspects.

First, the machining accuracy problem caused by the equipment is generally due to the systematic error of the machine tool itself and the error caused by the runout in the operation of the machine tool. During the use of the machine tool, the core parts such as the lead screw wear, resulting in increased clearance, the greater the machine tool error, and then the machining accuracy of the CNC lathe;

Second, in the process of CNC lathe processing, the choice of tools is particularly important, unsuitable tools will lead to the machining process of machine load is too high and tool wear too fast, resulting in CNC lathe accuracy can not meet the product requirements;

Third, the cutting parameters set during the programming is also one of the reasons why the machining accuracy of CNC lathe cannot be guaranteed, and the cutting parameters of feed and revolution must be set in combination with tools, material characteristics and equipment, so as to ensure the accuracy of CNC lathe processing

Fourth, in the process of CNC lathe processing, the reference error of the product is also one of the reasons why the machining accuracy of CNC lathe cannot meet the requirements, and the number of clamping times is minimized by turning and milling composite processing. It can reduce the influence of CNC lathe machining accuracy caused by the change of the benchmark in secondary machining.
