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.

After the machining of CNC precision machining PA parts, the surface of parts will reveal cyclic pattern, and it is difficult to polish. Metal parts can be polished with different type of sandpaper. However, if you polish CNC precision machining PA parts with sandpaper, a layer of paste will form on the sandpaper and the effect is little. Bordersun use woodworking polishing machine, the polishing speed is the same with metal polishing. If you paint directly on the surface, the paint will peel off. To enhance the adhesion of painting on surface of PA material, a layer of special coating is necessary, then painting and coloring can be made.
The curved edge of the workpiece should be polished carefully. When processing CNC precision machining PA parts, many small plant will make the “R” angle into right angle. Bordersun customize plan and specification for each project, strictly control the manufacturing process, make examination and test before stepping into next process to prevent the NG product flow into next process. A project engineer will be assigned to follow each project to ensure the quality and progress, guaranteeing the CNC precision machining PA parts you receive are exactly what you want in dimension, assembling, and surface treatment, and to make sure you can get them in time.
