Ellesco has announced that Plymouth Metal Polishing has expanded its industrial metal finishing facility with an investment in three Autopulit machines for linishing and polishing.

The three machines installed by Ellesco are proving to be highly productive and are bringing many advantages to Plymouth Metal Polishing.

For example, a twin-headed, flat-bed linisher is being used to take flat bar or box section components to a high level of surface finish.

The standard achieved by the machine is such that it satisfies almost all of Plymouth Metal Polishing’s requirements, with only components that require ‘super finishing’ needing additional operations.

The installation of the linisher has brought marked improvements to productivity and the working environment.

Steve Kelly, managing director of Plymouth Metal Polishing, said: ‘The advantage of this Autopulit machine is that it uses water as part of the polishing process, which means that there is no requirement for dust extraction.

‘It also eliminates any burning or deformation of the component.

‘As a result, we are seeing a 20-fold increase in throughput compared with the old processes that we used.

‘Most components only have to pass through the machine once to achieve the finish that is required.

‘The result of this improvement is being seen already, with one customer increasing the number of parts we are doing for it from 20/month to 80/week.’ For tube components, Kelly opted for two twin-headed Autopulit centreless grinding and polishing machines.

One machine is set up for linishing the raw tube, while the second is permanently set for polishing.

The first machine uses a water system to eliminate dust, heat and any deformation of the parts, and the finish achieved is described as a ‘satin finish’.

This is acceptable for many applications in the construction industry.

However, to obtain the highly polished finish demanded by customers in the exclusive world of super-yachts, tube is transferred to the second machine, which is set up specifically for polishing.

As with the first machine, the feed rate of the tube past the twin-heads is infinitely variable, allowing the optimum surface finish to be achieved.

This is also helped by the programmable system that sprays polishing fluid onto the buffing wheels at pre-defined intervals.

Kelly said: ‘The market for tube-based components will always be there as customers for these products are so diverse, with parts being supplied as table legs for a super-yacht cabin or a relatively mundane railing for a commercial building.

‘This fact was instrumental in our decision to invest in this equipment and ensure that we are as efficient as possible in order to build on that side of the business.

‘These machines allow us to be competitive due to the efficiencies that we are seeing, while at the same time we are able to demonstrate improvements in quality and consistency.

‘This is resulting in new business, some of which is coming from overseas customers.’ Plymouth Metal Polishing said the process was made easier thanks to the service and support it received from Ellesco.
