Precision Components Machining and Processing1. Precision Components Machining and ProcessingOverview of Precision Components MachiningIn the manufacturing process of precision mechanical components, under the condition ofensuring the quality of the precision parts, the course to develop a process plan withcomprehensive technical and economic benefits, reasonable and feasible process is referredto the process design of components. Production process: a product has to go through aseries of manufacturing processes from the design drawings into products. Usually, theprocess that from the raw materials or semi-finished products to the finished products iscalled the entire production processing, and every process is consisted of parts machiningprocess, a combination of many processes, and installation. And all the Accurate MetalFabricators of each step are very familiar with the machining techniques.Processing Characteristics of Precision PartsUsually, there are three ways to process the profiled section parts: First, direct formingmethod, such as casting, forging and stamping; Second, cutting motion synthesis method,such as cars, milling, planing, grinding, etc.; Third, the special processing method, such aswire cutting, EDM , laser machining, etc.; Among them, the direct molding method is the mainmolding method of the profiled section parts moulding, but because of its lowermanufacturing accuracy, and the surface roughness value is large, it cannot meet therequirements of the finishing of the profiled section parts. So special processing methodcannot 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 thatthey can process a variety of parts of complex shapes. In these methods, milling and planingare still difficult to obtain high machining accuracy. Grinding is a common precision metalproduction and processing method for Precision Components, and it has higher productionefficiency.Lathe Machining of Profiled Precision-section Parts2. The method of lathe machining of profiled precision-section parts are mainly: the mechanicalmotion synthesis method, namely through the multi-directional movement of the bodies toachieve turning trajectory of the profiled section; shape-imitating processing method, namelyto use the relative motion of the cam control turning tool and the workpiece track to form thedesired shape of the workpiece; CNC turning method, CNC lathe uses the programinstructions to control the machine, and the machine automatically complete the process.Among them, CNC turning method has the highest production efficiency and precision, stablequality, 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 toadjust the CNC program then you can complete the processing operations, it is particularlysuitable for automated production of small quantities.This article come from:www.halopart.com
