Do you get a lot of CNC and laser cut parts for your fabrication and supply business. We have the capability to deburr mass parts in our tumblers. A client took the opportunity to have 250 of each part deburred. The process was previously done manually adding increased cost in labour and consumables to complete the work. Using our deburring service for parts allowed the client to better utilise labour on other work whilst having 500 parts deburred using our vibratory tumblers. Reduce cost, increased productivity, better labour utilisation.

Call for a price and to discuss your needs.

We have 2 machines available for deburring.
A 550mm wide x 2 mtr trough and 600mm bowl for smaller parts.

Parts are deburred, cleaned in inhibitor to stop flashing rust, quality check completed.

Parts can be either prime in wet primer or powder coated in house also.

We have been busy with some speedway teams with the treatment of diff ring and pinion aswell as diff gears.

With magnesium diffs the magnesium holds the heat in the diff casing creating higher operating temps during racing. In additional to the thermal coatings team opt for isotropic superfinishing treatment provides cooler running options simply be reducing friction once treated. Additional to heat benefits, diff gear treatment provides
- Reduces friction (creates low cost Horsepower. Whats the cost of a % gain in motor performance)?
- Lower operating temps
- Increased reliability
- Improved gear lubrication.

Isotropic superfinishing treatments have been used for some time now at the highest levels of motorsport.
