Precision Components Machining and Processing

Overview of Precision Components Machining

In the manufacturing process of precision mechanical components, under the condition of ensuring the quality of the precision parts, the course to develop a process plan with comprehensive technical and economic benefits, reasonable and feasible process is referred to the process design of components. Production process: a product has to go through a series of manufacturing processes from the design drawings into products. Usually, the process that from the raw materials or semi-finished products to the finished products is called the entire production processing, and every process is consisted of parts machining process, a combination of many processes, and installation. And all the Accurate Metal Fabricators of each step are very familiar with the machining techniques.

Processing Characteristics of Precision Parts
Usually, there are three ways to process the profiled section parts: First, direct forming method, such as casting, forging and stamping; Second, cutting motion synthesis method, such as cars, milling, planing, grinding, etc.; Third, the special processing method, such as wire cutting, EDM , laser machining, etc.; Among them, the direct molding method is the main molding method of the profiled section parts moulding, but because of its lower manufacturing accuracy, and the surface roughness value is large, it cannot meet the requirements of the finishing of the profiled section parts. So special processing method cannot be widely processed due to low efficiency, high cost and complex axial cross-sectional shape of a non-circular cross-section parts and it has limited application. Lathing, milling, planning and grinding are the most common sports synthetic cutting methods that they can process a variety of parts of complex shapes. In these methods, milling and planing are still difficult to obtain high machining accuracy. Grinding is a common precision metal production and processing method for Precision Components, and it has higher production efficiency.

Lathe Machining of Profiled Precision-section Parts
The method of lathe machining of profiled precision-section parts are mainly: the mechanical motion synthesis method, namely through the multi-directional movement of the bodies to achieve turning trajectory of the profiled section; shape-imitating processing method, namely to use the relative motion of the cam control turning tool and the workpiece track to form the desired shape of the workpiece; CNC turning method, CNC lathe uses the program instructions to control the machine, and the machine automatically complete the process. Among them, CNC turning method has the highest production efficiency and precision, stable quality, and has a wide range of processing, and it can be used for various shaped cross-section parts automatically turning. When the processing objects change, you just need to adjust the CNC program then you can complete the processing operations, it is particularly suitable for automated production of small quantities.
