Aiming at the process characteristics of cnc machining centre does all the work of, cnc machining centre does all the work of is suitable for processing complex shapes, many processing contents, high requirements, and requires a variety of types of ordinary machine tools and numerous process equipment. Multiple clamping and adjustments can be used to complete the processed parts. The main processing objects are as follows.
1. Parts that have both flat surfaces and holes
The cnc machining centre does all the work of has an automatic tool changer. In one installation, it can complete multi-step processing such as milling, drilling, boring, reaming and tapping of the parts on the plane. The processed parts can be on one plane or on different planes. The pentahedral machining center can process five surfaces except the clamping surface at one time. therefore. Parts with both planes and holes are the first choice for machining centers. Such parts commonly include box parts and trays, sleeves, and plate parts.
(1) Box body parts, there are many box body parts, which are several common box body parts. Box parts generally need to be processed with multi-station holes and planes, with high accuracy requirements, especially the requirements for shape accuracy and position accuracy are strict, usually through milling, drilling, expanding, boring, reaming, tapping and other steps , It requires more tools, it is difficult to process on ordinary machine tools, there are many sets of tooling, it needs to be clamped and corrected many times, and the number of manual measurements is large, and the accuracy is not easy to guarantee. The last installation of the machining center can complete 60%-95% of the process content of the ordinary machine tool. The accuracy of the parts is good, the quality is stable, and the production cycle is short.
(2) Discs, sleeves, and plates. These parts have flat surfaces, curved surfaces and holes on the end faces, and some radial holes are often distributed in the radial direction. Vertical machining centers should be selected for disk, sleeve, and plate parts whose machining parts are concentrated on a single end surface, and horizontal machining centers should be selected for parts whose machining parts are not on the surface in the same direction.
