Which products can be processed by CNC machining centers?
The machining center is suitable for complex machining, many processes, and high requirements. It requires various types of ordinary machine tools and many tools, fixtures, and parts that can be processed after multiple clamping and adjustment. The main objects of processing are box-type parts, complex surfaces, shaped parts, plates, sleeves, plate parts and special bead processing.

Auto metal parts


CNC machining of box parts


Box parts generally refer to parts with more than one hole system, internal cavity, and a certain proportion in the length, width and height directions. These parts are used in machine tools, automobiles, aircraft manufacturing and other industries. Class parts generally need to carry out multi-station hole system and plane processing, and the tolerance requirements are relatively high, especially the geometrical tolerance requirements are strict, usually through milling, drilling, expanding, boring, reaming, boring, tapping and other processes, There are many kinds of tools, it is difficult to process on ordinary machine tools, the number of tooling sets is high, the cost is high, the processing cycle is long, it needs to be clamped many times, and the number of manual measurement is many. The tool must be changed frequently during processing. The process is difficult to formulate. The important thing is that accuracy is difficult to guarantee.
For the machining center of machining box parts, when there are many processing stations, the parts that need multiple rotation angles of the worktable can be used. Generally, the horizontal boring and milling machining center is selected. When the processing position is small, the span is not When large, the vertical machining center can be selected to process from one end. .


Auto metal parts


CNC machining complex surface parts


CNC machining centers are particularly important in the machining of complex curved surfaces in the mechanical manufacturing industry, especially in the aerospace industry. Complex machining surfaces are difficult or impossible to accomplish with conventional machining methods. In China, the traditional method is to use precision casting, and it is conceivable that its precision is very low.
Such as: various impellers, wind deflectors, spherical surfaces, various curved forming dies, propellers for propellers and underwater vehicles, and some other shapes of free-form surfaces, which can be processed by machining centers. More typical are the following


Auto metal parts

CNC machining center cam


As the basic component of mechanical information storage and transmission, cam is widely used in various automatic machines. These parts have various curved disc cams, cylindrical cams, conical cams, barrel cams, end cams and the like. Machining such parts can be based on the complex procedure of the cam, using a three-axis, four-axis linkage or a five-axis linkage machining center.

CNC machining



CNC machining integral impeller


Such parts are commonly found in aero-engine compressors, oxygen plant expansion machines, single-screw air compressors, etc. For the processing of such profiles, a machining center with four or more axes is required.

CNC machining mold

Such as injection molds, rubber molds, vacuum forming plastic molds, refrigerator foam molds, pressure casting molds, precision casting molds, etc.
The machining center is used to process the mold. Due to the high concentration of the process, the finishing of the key parts such as the movable mold and the fixed mold is basically complete machining in one setup, which can reduce the cumulative error of the size and reduce the workload of repairing. The mold has strong reproducibility and good interchangeability. Machining leaves the work of the fitter to a small amount. Wherever the tool can reach, it is done by mechanical machining as much as possible, so that the workload of the mold fitter is mainly polished.
