CNC machining is the way to process a piece of material (such as metal, plastic, insulation materials, etc.) by machine tools and fixtures with a coded programmed instruction. The main products of processing are Enclosure components, complex surfaces components, molds, and special processing products.
Enclosure components 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, and other processes.
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 CNC machining. The typical ones are as follows:
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.
The CNC machining 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 CNC machining can work with certain machining tools and special tools to complete some special bead work, such as lettering on the metal surface, engraving. The main shaft is equipped with a high-frequency electric spark power supply, which can perform wire scanning surface quenching on the metal surface, and install a high-speed grinding head on the machining center to realize small-module involute bevel gear grinding and various curves and curved surfaces.
