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.

The application of CNC technology has made a qualitative change in the traditional manufacturing industry, especially in recent years. The development of microelectronics technology and computer technology has brought new vigour to CNC technology. CNC technology and CNC equipment is an important foundation for the industrial modernisation of each country.

The manufacturing error of the machine tool covers various aspects such as spindle rotation error, guideway error and transmission chain error. Spindle rotary error, that is, the spindle in the actual rotary process, its axis and the average axis of the deviation between, which is directly related to the accuracy of the workpiece processing.

Mould has a complex structural profile, high precision requirements, high hardness of the materials used, short manufacturing cycle and so on. Mould manufacturing is a complex production process with tight production cycle requirements and high technical means. Each mould is a new project

01Titanium Alloys: Superiority and ChallengesTitanium alloys, a metal with high specific strength, excellent corrosion resistance, and excellent high-temperature mechanical properties, play a vital role in the aerospace industry.

Polishing of sanitary stainless steel tubes is a finishing technique designed to improve the finish and smoothness of the tube surface to achieve the desired surface quality. The polishing process usually involves “wet” polishing using fine micron or submicron abrasive particles in combination with a liquid.
