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.

Mold Heat Treatment Industry Development Strategies

Mainly in three aspects: First, the technical difficulty of the heat distortion control; constraining factors Guangdong mold heat treatment production ability capital expansion of the slow pace of the market environment in the industry; Third, the phenomenon of cohabitation remediation mold steel market . Die Network CEO, Shenzhen mold a member of the Society of expert Luo Baihui, the molds heat treatment industry sustainable development, we must promote the mold heat treatment of high-end quality, attention to the digestion of the unfavorable factors in the industrial environment.
Parts heat treatment distortion is an inevitable question is how its effective control. Is a major key to the quality requirements of the mold heat treatment to control distortion. With the advances in heat treatment technology and equipment, the ability to control mold heat treatment distortion is constantly improving. Although heat treatment of mold heat treatment distortion control bear a great responsibility, but mold heat distortion and mold structure design, the quality of raw materials, metallurgy, forging, pre-heat treatment and machining. If the side of the mold design, material suppliers, forging, heat treatment plant, and a mold factory organic coordination the mold distortion control will be more effective. But limited to the current market environment, organic coordination probably can not be too optimistic. Distortion of the mold in order to ensure the normal auto mold, small and medium-sized precision molds and medium-sized plastic mold such as heat treatment production control as the object of focus on research is necessary, it is quite urgent.
Heat Treatment Industry in Guangdong industrial capital expansion in recent years, the pace is slow, not shown good interaction with regional economic development results. Surviving in the industry in the phenomenon of low-level duplicated construction, investment diversification, generally small scale, as well as the waste of environmental resources "not strong". Situation the companies basically still in the "go it alone", not inter-enterprise technology to win but to win by playing the price war disorderly market is still fairly common practice, can not generate agglomeration spillovers. Industry meticulous specialization and specialized production, there is still much room for improvement in. Industry, lack of financing ability and good technical advantages "leader". The change in these situations must get the attention of the relevant departments, have a good industrial policy environment and technical back-up for support.
At present, Guangdong mold materials market chaos phase a lot of cohabitation, and the absence of regulation. Posing as "imported steel, domestic steel cottage steel" replace "brand steel" phenomenon often visible. Cr12 type cold work die steel key related to product quality chromium content (mass fraction) should be 12% chromium content in the market, however, is only 7%, or even lower so-called Cr12 steel, had "sexually explicit". Materials market chaos serious impact on the quality of heat treatment of mold, and also bring a great loss to the entire mold production, but also bring a lot of economic disputes, a great influence of the mold heat production boutique process. Purification mold steel market means necessary to improve the mold production competitive pay enough attention to deal with the remediation of the mold steel market.
