CNC grinding of small batches

G.W.P. AG specializes in the cost-optimized manufacture of small batches. We manufacture components and exclusive small series, even of demanding multi-axis machining by means of internal and external cylindrical grinding. We use cutting-edge CNC grinding machines with ceramically-bonded grinding wheels to produce superior surface quality and repeat accuracy with tolerances up to 1 µm. The available grinding systems enable the production of rotationally-symmetrical bodies as well as the grinding of complex surfaces. Our experienced employees manufacture high-quality ground parts according to your specifications by means of:

  • Fine grinding, flat honing
  • Profile grinding
  • Internal and external cylindrical grinding
  • Flat lapping, parallel lapping, round the lapping
  • Honing/cross grinding

Our branch-specific experience eliminates loss from poorly coordinated logistics, thus enabling your CNC-ground parts to be successfully completed on-schedule. Our proven project track record with customers from your branch makes it easier for us to quickly understand your special needs and problems and precisely satisfy your demands.
