If Dalian precision parts are machined with profiling device, space surface can also be machined, such as turbine impeller, spiral groove, etc. The tool structure of this kind of machine tool is simple and does not cut when returning, so its productivity is low. It is generally used in small batch production of single piece. Plane, gear teeth corridor, helical surface and various forming surfaces, can also grind cutters and cut, etc., the process range is very wide.

Because grinding is easy to obtain high processing accuracy and good surface quality, grinders should be applied to the finishing of parts, especially hardened steel and high hardness special materials. Ultra-high speed machining skills include: ultra-high speed cutting and grinding mechanism research, ultra-high speed spindle unit manufacturing skills, ultra-high speed feed unit manufacturing skills, ultra-high speed machining tools and abrasives manufacturing skills, ultra-high speed machining on-line active detection and control skills.

In precision parts processing, part measurement datum is mainly used to check the size and position of the machined surface. For example, the axis of the inner hole is the measurement datum to check the radial runout of the outer circle. Surface A is the measurement datum to check the length and ruler. Processing regulations for precision parts are technical documents guiding production, and they must be economical and reasonable.

The vigorous demand of CNC machine tool industry will continue to grow at a high speed. The annual composite growth rate of 37.4% has become the mainstream of machine tool consumption. During the 12th Five-Year Plan period, China will continue to invest, and intensify its efforts. Major special projects will drive more than 10 billion yuan of investment annually. Mainly the size requirements, such as the diameter of the cylinder, there are strict requirements, positive and negative errors are qualified parts within the prescribed requirements, otherwise they are all unqualified parts; length, width and height also have specific strict requirements, positive and negative errors are also prescribed, high reliability of die products and strict technical management. Die fine manufacturing is not a single technology, but a comprehensive reflection of design, processing and management technology.
