Non-standard parts CNC machining skills

Metal non-standard parts are provided by customers with drawings. Manufacturers use equipment to produce corresponding products according to the drawings. Usually, most of them are molds. Tolerance requirements and smoothness are specified by customers, and there is no certain paradigm. Products from casting to finishing completely need corresponding quality control, the process is complex and variable, and the cost is generally higher than that of standard parts. Non-standard parts are indispensable for modern industry.

Processing skills:

(1) To see how to process non-standard parts, first look at the classification of machine tool parts: the important parts of machine tools can be divided into: box, base, spindle, flange, sheet, etc.

(2) Production process classification: Different processes correspond to different equipment: lathes (including CNC, ordinary lathes), milling machines, planers, grinders, radial drills, wire cutting machines, heat treatment furnaces, etc.

The process of changing the size or function of the workpiece is called non-standard parts. Cold working and hot working are divided according to the temperature conditions of the workpiece to be processed. It is usually processed at room temperature and will not cause any chemical or phase changes to the workpiece. called cold working. Generally, processing higher or lower than normal temperature will cause chemical or phase transformation of the workpiece, which is called thermal processing. According to the processing method, cold working can be divided into cutting processing and pressure processing. Heat treatment usually includes heat treatment, forging, casting and welding.
