01 Error and accuracy of the “twin faces” of the smaller the machining error, the higher the degree of compliance, the higher the machining accuracy. Both actually describe the same thing - just a different perspective. In other words, the size of the error directly determines whether the part can meet the standard!

Machining error is the degree of deviation between the actual geometric parameters (geometric dimensions, geometric shape and mutual position) and the ideal geometric parameters of a machined part.

When the original accuracy of the machine tool, cutting tool, fixture and workpiece blank etc. all meet the process requirements without considering the dynamic factors, the effect of adjustment error plays a decisive role in machining accuracy. Improve the geometric accuracy of the machine tool used for parts machining

The emergence of mill-turn machining equipment provides an effective solution for improving the machining accuracy and efficiency of aerospace parts. With the continuous development of CNC technology, computer technology, machine tool technology and machining process technology

Boring, refers to the forged, cast or drilled holes for further processing. Boring can expand the hole diameter, improve accuracy, reduce surface roughness, but also can better correct the original hole axis of the skew. Boring can be divided into rough boring, semi-fine boring and fine boring.
