Processes & Skills : Manufacturing & Inspection facilities

Supported by a programme of on-going investment, we have modern and sophisticated machine tools and the latest inspection equipment.

Production equipment

Our range of equipment comprises manual, automatic and NC machines for :

  • Diamond grinding  : surface grinding, cylindrical grinding, centerless grinding, honing, milling-drilling, lapping-polishing
  • High-precision ultrasonic machining

Some of the dimensions and tolerances that we can meet are shown in the here above table :

  Maximum dimensions Minimum dimensions Tolerances
Surface grinding      
3-axis automatic L 1200 x W 400 x H 380 mm Thickness : 100 µm 5 to 10 µm
4-axis NC L 120 x W 100 x H 15 mm Width of grooves : 100 µm < = 5 µm
Milling / Drilling      
3-axis NC milling & ultrasonic L 600 x W 500 x H 350 mm Hole diameter : 0,5 mm 5 to 10 µm-position tolerance depending upon the size of the part
NC miller L max 1000 mm    
Honing ID. 90 mm ID. 1,7 mm < = 5 µm
Lapping / Polishing Flat surfaces : OD 200 mm
Cylinders : OD 60 mm
  Flatness 0,33 µm


In addition to existing CAM tools delivered with NC machines, we have invested into Solid-Works software in order to increase our ability to work in a more efficient manner with our customers and provide our skilled operators with leading-edge tools for programming our NC machine tools.

Cleaning equipment

A dedicated room is equipped with utlrasonic washing equipment and the cleaning agents are based on water and detergents. We also have a batch kiln that enables us to clean-fire parts at high temperature (1350°c maximum)

Inspection equipment

We have conventional tools to which more sophisticated equipment have been added to. Two dedicated rooms - one of which with air-conditioning – are available.


  • Height gauges
  • Optical coordinate measuring machine
  • Mechanical coordinate measuring machine
  • Laser bench
  • Perthometers

Visual inspection

  • Binoculars
  • Shadowgraph
  • Optical measurement
  • Dye-test
