Precision CNC machining parts is a relatively popular processing method nowadays. Relying on high precision, the machining accuracy of the parts can be improved during processing, and the machining quality of the surface can also be improved. After machining, the quality and various aspects of many parts have been improved. .
Precision CNC machining
Complex shape and surface Some products, such as car covers, aircraft parts, toys, and household appliances, have a surface that is composed of a variety of curved surfaces. Therefore, the mold cavity surface is very complicated. Some surfaces are processed mathematically.
Precision CNC machining requires high machining accuracy. A pair of molds is generally composed of concave molds, punches and mold bases, and some may also be multi-piece splicing modules. Therefore, the combination of the upper and lower molds, the combination of the insert and the cavity, and the splicing between the modules all require high machining accuracy. The dimensional accuracy of precision molds often reaches μm level.
The use of repetitive production molds has a lifespan. When the use of a pair of molds exceeds its life, it is necessary to replace a new mold, so the production of molds is often repetitive.
The production of batches of small molds is not mass production, and in many cases only one set is produced.
Precision CNC machining process Multi-mold machining always uses various processes such as milling, boring, drilling, reaming and tapping.
In the production of profiling molds, there are sometimes neither drawings nor data, and profiling is carried out according to the actual objects. This requires high imitation precision and no deformation.
