On stand N67 at Southern Manufacturing, vibratory-finishing specialist PDJ Vibro Ltd (www.pdjvibro.co.uk) will
be promoting its comprehensive range of new and refurbished bowls, barrels and high-energy centrifugal equipment, along with its comprehensive range of consumables — plus its repair and sub-contract finishing services.

The equipment ensures that the deburring, descaling, edge breaking, surface finishing and super-finishing of components is carried out automatically, and to a degree of repeatability that is unattainable when processing by hand. At the same time, parts can be degreased, rinsed, dried and pre-treated for anodising, chemical blacking or painting. More than 120 machines are available for inspection at the supplier’s Bletchley headquarters, which houses a showroom, technical centre and demonstration facility.

The controlled dosing of additives, water metering and recirculation, automatic parts separation, drying and acoustic suppression can be supplied with the machines.

PDJ Vibro can also provide free process advice, which takes into account the number of parts to be finished per batch, frequency of production, drainage and noise issues, the size of components and how vulnerable they are to damage by impingement.

Finishing trials and sample processing are also offered, along with flexible payment and buy-back solutions.

Designed for mass processing of small to medium-size components, the company’s main high-end vibratory-bowl range has chamber sizes from 7.5 to 6,000 litres; there are also three lower-cost entry-level models that have chamber capacities of 300, 150 and 75 litres. Meanwhile, rectangular troughs come in 13 different sizes with capacities from 22 to 2,200 litres.

These are the preferred choice for finishing larger prismatic items and those made from flat sheet metal, as well as delicate components that are susceptible to impact damage.
