Precision parts processing has extremely strict requirements, processing a little careless will lead to workpiece error beyond the tolerance range, need to be reprocessed, or announced blank scrap, greatly improve the cost of production. Therefore, today, SZBJ Co., Ltd. talks about the precision parts processing requirements? Can help us improve production efficiency.
The dimension of the workpiece must be processed in strict according to the shape and position tolerance requirements of the drawing. Although the parts processed and produced by the enterprise are not exactly the same as the size of the drawing in fact, the actual size is within the tolerance range of the theoretical size, which belongs to qualified products and can be used.
CNC machining manufacturers equipment requirements, rough and finish processing should use different performance of equipment. Because the roughing process is the cutting of most parts of the blank, the workpiece in the case of large feed, large cutting depth will produce a lot of internal stress, at this time can not be finished. When the workpiece is finished after a certain time, it should be worked on the machine tool with high precision, so that the workpiece can achieve high accuracy. SZBJ has tens of millions of equipment assets to guarantee customers' products with high quality and high quality control on time delivery
The processing of precision parts often involves surface treatment and heat treatment. Surface treatment should be placed after precision machining. And in the process of precision machining, the thin layer thickness after surface treatment should be considered. Heat treatment is to improve the cutting properties of the metal, so it needs to be done before machining。
SZBJ can offer cnc milling machining, CNC turning machining, CNC lathing maching, CNC bending processing, sheet metal fabrication, 3-5 axis precision machining equipments, ODM/OEM for kinds of metal and plastic products, one-stop machining service factory.
