Perfect Bore is proud to have Sunnen & Delapena Horizontal Honing, Vertical & CNC Tube Honing machines that will hone all bores from 1.5mm to 340mm. The horizontal honing division is temperature controlled, producing bores from 1.5mm to 165mm diameter up to a depth of 300mm and match hone to 0.0015mm, working down to the following tolerances:
- Geometry within 0.001mm
- Roundness within 0.001mm
- Surface finish within 0.01Ra
