Three kinds of precision description of CNC centring machine

In the process of CNC centring machine, centring gauge processing accuracy has been further ensured. Generally speaking, in the process of using CNC centring machine, the processing diameter is relatively small, the processing diameter of only 38 mm, the continuous development of technology makes the centring gauge in the precision shaft processing has greater advantages. On the enterprise, the use of CNC centring machine can be useful to reduce labour costs, on the reduction in the production of defective products have an important impact and significance.

　　CNC centring machine accuracy is divided into the following different types, respectively: static accuracy, positioning accuracy and dynamic accuracy, next let us understand together.

　　1, static accuracy: general reflection of the general geometric shape of the key components of the machine after assembly fault. Static precision includes geometric accuracy and positioning of the axis screw and open space, dynamic precision for the product of the successive processing of the stability of the shake detection, testing tools for the precision of the nano-level, each geometric accuracy of the specific testing methods and standards are in accordance with the precision of the machine tool factory testing project requirements for testing. The static accuracy of the good and bad directly affects the normal use of machine tool CNC function and function. Therefore, the accuracy check on the initial use of CNC centring machine and repair and adjustment of the machine tool after the technical indicators of rehabilitation is very important.

　　2, dynamic accuracy: is a general accuracy, it not only reflects the geometric accuracy of the machine tool and machining stability, together with the specimen also contains the material, fixture, ambient temperature, CNC machine tool function and cutting conditions and other factors caused by faults and measurement faults. In order to reflect the real accuracy of the machine tool, to try to eliminate the influence of other factors.

      3, positioning accuracy: is the index-controlled centring machine axes in the CNC equipment under the control of the movement can reach the orientation accuracy. Positioning accuracy can also be understood as the movement accuracy of the machine tool. General machine tools are manually fed, positioning accuracy is determined by the primary reading faults, while the movement of the CNC walking machine is dependent on the end of the digital programme instructions, so the positioning accuracy is determined by the CNC system and mechanical transmission faults. Machine tool work is under the control of the end of the CNC equipment, each moving parts can reach the accuracy directly reflect the accuracy of the processed parts can reach, so the positioning accuracy is a very important test content.
