The dimension of PC is stable, and it can keep the rigidity in wide range of temperature. And even in low temperature, PC still has great anti-impact strength. CNC precision machining PC parts are mainly used for the complex parts with curved surface, like impeller, air inducer wheel, spherical surface and propeller.
Filings splash during the cutting of metal. The cutting of CNC precision machining PA parts is different from that of metal. It is like the process of pencil sharpening, with scraps winding around the cutter. During the process, scraps accumulate and temperature rises, and PA scraps will melt and adhere to the cutter. It is difficult to clean. The common solution is slowing down the cutting speed, lifting the cutter intermittently and adding coolant liquid. However, during the processing of PA, the scrap is filiform and tangled, and it cannot be washed away by the coolant liquid. Blower gun is more effective than coolant liquids. And we use high pressure blower gun to blow constantly to prevent the conglutiantion of nylon filament with the cutter.
CNC Precision Machining PMMA Parts performs good in electrical insulation and machinability. The transparency of CNC machining PMMA parts can be 95% after polishing, and PC is incomparable. There are transparent materials among PC too, but the transparency is not as good as PMMA.
PP performs excellent in anti-impact strength, fatigue resistance and machinability. For small batch PP parts, usually we will choose CNC precision machining PP parts.
CNC High Quality Jigs and Fixtures are often used in the mould manufacturing, precision machining, EDM forming, metal machining and rapid reloading of production line. During the processing, the device used to reload the workpiece quickly, conveniently and safely is call jigs and fixtures. Like jigs and fixture of welding, checking, assembling and machining. They can complete the repetitive work accurately and conveniently, reducing labor cost and enhancing working efficiency.
As a diversified metal, copper can meet the unique demand of various products, producing more suitable jigs and fixtures of the products’ tensile test. The main materials of high precision copper jigs and fixtures are copper and copper alloy rod. They perform good in electrical and thermal conduction, and their electrical and thermal conductivity are only second to silver.
