Products & services
Premier Superfinishing Service
Superfinishing parts from 10mm to 340mm diameter up to 1M in length with a fully supported toolroom & inspection facility. Perfect Bore prides itself on producing 100% inspection reports when required and has a fully controlled logistics division to ensure customers’ parts are 100% traceable when at our facilities. Inspection equipment includes: Opticline C310 (automatic optical non-contact measuring system) 2D vision shadow projector for measuring radii Passometer measuring roundness and diameter Bore sizing & geometry measurement: mechanical, air & electric gauging to measure accuracy within 0.001mm Portable Faro Arms Roundness measurement: Talyrond TR 252 to measure accuracy within 0.0002mm Surface finish measurement: Surtronic 3+ (20,000 magnification surface finish analysis software) to measure accuracy 0.01 Ra (0.4 CLA) Concentricity & wall thickness measurement: Ultrasonic wall thickness to measure accuracy within 0.050mm.
CNC Grinding
A fully managed, supported & temperature controlled CNC Division with Studer Grinding Machines which will hold parts from 3-300mm diameter up to 1000mm in length. Ideally suited for machining parts such as spools, valves, rotor shafts, turbine shafts, turbine wheels etc, in all materials from mild steel to Inconel. Manufacturing features include: Parallel grinding down to 3 microns Face grinding to sub 3 microns squareness to face Producing radii from 0.2mm to 30mm Angle approaches from -8.5° to +8.5° Producing grooves from 1mm to 50mm Profile grinding Measuring equipment including: Opticline C310 (automatic optical non-contact measuring system) 2D vision shadow projector for measuring radii Passometer measuring roundness and diameter
CNC Turning
The CNC division includes 4 Doosan Puma turning centres that can machine up to 900mm diameter and up to 3.2M in length with a 5-tonne lifting capability. With our processes and machinery, we can control the surface finish on challenging diameter to length ratio bores, with the ability to control thin wall sections and allow for rapid stock removal.
Honing
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
Gundrilling
Perfect Bore is proud to have a vast array of Mollart and TBT centreline, blockwork & CNC gundrilling machines that will produce bores from 1.8mm to 40.00mm diameter with a fully supported toolroom and inspection facilities including Faro arms.
Deep Hole Boring Services
Bespoke designed and built Deep Hole Boring/STS Drilling machines that produce bores from 25mm to 400mm diameter with a 5.0-tonne lifting capability with a fully supported toolroom & inspection facility.
