Precision grinding

Impeccable surface finishing with latter-day technology

In addition to the two existing Kallenberger machines, with 1 m and 1,5 m distance between centers, we installed a new precision grinding machine in our Trio OilTec facility in Stavanger. With this equipment we can now obtain a surface finishing on both hard and soft coatings including HVOF, arc spray, PTA, hardened and mild steel. Equipped with cutting-edge equipment, we now have the capability of grinding most of the tools used within the Oil & Gas industry.

Machine capacity:

  • Rod maximum length: 4000 mm between centers
  • Rod maximum diameter: 570 mm
  • Surface finish Ra: 0,2
  • Roundness of work piece: 0,002 mm
