Precision CNC parts manufacturing accuracy requirements:
CNC metal parts

1, For Metal CNC machining of machine tools, the accuracy of the product refers to the allowable tolerance range of the product design theory and the actual production of the product.

2, The measurement accuracy is the drawing size data and the actual Machining parts measurement data close. Including accuracy and precision two aspects.

3, The roughness of metal CNC products is Ra0.3 ~ 0·03μm, the accuracy is 3 ~ 0.3 μm called precision machining.

4. At present, the most widely used high precision machine tool manufacturing processes of CNC manufacturing include grinding, grinding, polishing, lathe and other processes.

5, The metal product surface finish data is 0.8, if it is Ra value is precision machining, if it is Rz value, it is ultra-high precision machining.

6. In machine tool processing, tolerances indicate the manufacturing accuracy requirements of metal parts and reflect the degree of manufacturing difficulty.
