Immediately inside the visitor entrance to Surface World Live 2018 (19-20 September, Birmingham NEC), vibratory finishing specialist PDJ Vibro will promote its range of new and refurbished bowls, barrels and high-energy centrifugal equipment, as well as the large range of consumables on offer.

The company will also stress its comprehensive service offer, from technical consultancy and applications engineering, through machine upgrade, repair and part-exchange, to 24/7 subcontract vibratory finishing and polishing.
Vibratory machines ensure that deburring, descaling, edge breaking, surface finishing and superfinishing of components is carried out automatically, consistently and to a high degree of repeatability that is unattainable when processing by hand. The process also reduces labour costs, reworking and scrap. At the same time, parts can be degreased, rinsed, dried and pre-treated for anodising, chemical blacking or painting.
Another area of focus will be the vast range of components that can be efficiently and safely processed using the vibratory technique. Anything from rusty old chains to parts machined to tolerances measured in single-figure microns are suitable candidates for vibratory finishing, as are delicate components produced by additive manufacturing.
PDJ Vibro’s main vibratory bowl range has process chamber sizes from 7.5 to 6000 litres, while three entry-level models have capacities of 300, 150 and 75 litres. Rectangular troughs in 13 sizes, with capacities from 22 to 2200 litres, are the preferred choice for finishing longer items and those made from sheet metal.

Master Abrasives has installed a Micromatic Eco 200 grinding machine at the facility of Border Ballistics Technologies (BBT) in Scotland.

Geoffrey Kolbe, managing director of BBT, has been in the non-military gun trade for over 25 years, establishing the company in 2015 to fill a gap in the UK market. The company is a manufacturer of gunsmith tooling such as chamber reamers and headspace gauges, all of which are produced with high-quality finishes and precision.
“In line with market demand we needed to increase our production output,” says Kolbe. “We identified that by taking the basic blank preparation operations off our tool and cutter grinder, productivity would increase with the introduction of a manual/semi-automatic cylindrical grinding machine. The Micromatic Eco 200 supplied by Master Abrasives proved to be the ideal machine for this purpose, and the price was very reasonable too.
“The production of special purpose bespoke stepped reamers and headspace gauges in tool steel demands very tight tolerances on specific dimensional features such as outer diameters, angles and faces,” he continues. “The Eco 200 manual/semi-automatic hydraulic machine fulfilled our requirements perfectly. Its introduction into production will improve our manufacturing lead-times and contribute to lower production costs.”
The new machine at BBT has a 400 mm grinding capacity between centres and an additional internal grinding spindle. The wheel-head’s nitride hardened steel spindle runs in precision multi-point hydrodynamic bearings, a configuration that gives very
high rigidity and damping.
“Master Abrasives provided a very professional service from start to finish,” says Kolbe. “The machine was delivered on time and was up and running within a couple of days.”
