Polymeric details for the chemical industry
Precision turning plastics
The component examined in the video is a ring nut that is mounted as a component of pumps used in the chemical industry. In this context, surface finishes with a low roughness value are required, and specifically in the piece being processed not only in the central area, but also on the front and back faces.
The use of a CNC turning center equipped with a double spindle and the use of a machining cycle specially prepared to machine plastic materials, made it possible to
overcome these critical issues and to obtain, with a single setup, the numerous front and perimeter holes specified in the drawing, while the use of the double turret installed on the machine, made it possible to reduce the execution times compared to a machining operation performed on a traditional CNC lathe.
The part was manufactured, by turning, using, as raw material, acetal resin (POM) semi-finished products, a polymer that ensures excellent machinability and allows to obtain precise parts with an excellent surface finish.
