CNC Turning

 

 
  • 13 no CNC machining centres
  • 2300mm x 800mm maximum capacity
  • Components up to 1000kg
  • Vertical, horizontal and twin pallet machines                                                                               

 

Spark Wire Eroding

 

  • Complex, contoured shapes easily produced
  • Allows machining of exotic materials such as super alloys, tungsten carbide, titanium etc
  • Dimensional consistency throughout batches
  • Elimination of heat distortion allowing hardened components to be machined                             

 

Surface Grinding

 

                                      
  • Surface grinding generates the super finish necessary prior to lapping or carbide coating
  • Cylindrical grinding provides not only the required finish on components manufactured from most base metals but also on components before and after hard chrome plating
  • Rotary grinding ensures highly efficient stock removal

 

Honing

 

  • A cost-effective precision honing service
  • State of the art machine technology
  • Faster production turnaround supplying components COMPLETE removal.                               

 

Lapping

 

                 
  • Stock removal controlled to within a few microns
  • Flatness to 1 light band
  • Surface finishes, using either conventional abrasives or diamond super abrasives, to obtain leak-proof mating without gasketing
