CNC Turning High-Performance Plastics

CNC Turning of PEEK, PTFE, or PPSU – precision turned parts from Seevetal near Hamburg

KURIOS Laserprodukt GmbH processes plastics in all variations. Besides engineering and advertising plastics, the use of high-performance plastics increases constantly. In many modern production facilities these high-temperature resistant and chemically stable materials fulfill tasks that other materials can hardly achieve, if at all.
It is very rare that classic clamping and machining parameters from metal-based jobs can be used for this group of plastics, which is why we need to consider every material’s unique characteristics. Relatively soft PTFE, for instance, requires that each clamping situation is thought through from scratch. Other plastics have abrasively acting additives, which complicates the selection of suitable machining tools or indexable inserts.

Your product’s contours can be programmed offline by using latest CAD/CAM technology (e.g.: SolidWorks) or SIEMENS SinuTrain. Usually, most of the simple turning jobs are programmed directly at the machine by means of ShopTurn.
Quality assurance of your components is continuously happening throughout the entire manufacturing process and the records are stored in our ERP system “KISS”. All production data is archived, so that any product is fully traceable and reproducible.
Our young and highly motivated team in the production area of machining is looking forward to your request regarding CNC turning of plastic. Feel free to contact us.
