Mass Finishing Process in a Reduced Time - Axle Holder

ActOn Finishing develops a single step mass finishing process for an axle holder, benefiting the end-user by eliminating manual finishing and producing a repeatable and quality finish.

ActOn Finishing was approached by one of its customers to develop a mass finishing process for an axle holder. The customer manufactures forge automotive parts for the motorcycle industry. They were manual polishing the components and were looking to implement vibratory finishing in their process. However, at the time they had no experience with mass finishing techniques and they needed some guidance.

The mass finishing process aim

  • To achieve a descaled, deburred and bright finish
  • The customer has very high manufacturing volumes and there is a required throughput to be achieved. Hence we had to determine the most efficient mass finishing process for the part.

What we did

We started by working out the weekly volumes and we determined that the mass finishing process should be no longer than 15 minutes. As a normal vibratory bowl may not achieve the required finish within the time frame, we decided the most appropriate finishing technology to use is the Centrifugal High Energy finishing machine. Furthermore we have identified that by using divider plates in the High Energy finishing machine barrels, we can process 12 parts per load.

Our team also developed a unique finishing process, using a single type of media and compound. As the axle holder is manufactured out of Aluminium we used a medium abrasive ceramic media for descaling and deburring. We carefully chose the media size and shape to avoid any lodgment while managing to finish even hard to reach areas of the part.

Beside using the correct machinery and media the compound was integral for the success of the finishing process. We used a liquid compound that acts as a concentrated cleaner and a good polisher. Furthermore the compound has other functions such as:

  • Suspending the dirt and media residues and flushing them from the system
  • Keeping the components and media clean, which brings stability to the process
  • Acts as a lubricant, thus extending the media life

The result

The process resulted in complete scale removal and a deburred and bright finish all in a single step process, thus achieving the throughput.

Axle Holder before and after


  • Achieved the required finish in a reduced processing time.
  • Avoided any part impingement by using the divider plates.
  • Produced a repeatable and quality finished product.
  • Simplified the finishing process by developing a single step finishing solution and using one type of media and compound.
  • Customized the finishing process as per customer’s needs
