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.

The latest Kellenberger 100 Concept cylindrical grinding machine will feature on the Hardinge stand at the forthcoming AMB 2018 exhibition (18-22 September, Stuttgart).
In terms of functionality, the Kellenberger 100 Concept, which was launched last year, delivers a range of configuration alternatives to meet the widest range of grinding applications. Modular construction based on a common platform is designed to reduce machine build time yet accommodate numerous ‘standard’ options with a good price-to-performance ratio for the end user, says the company.
Three important features distinguish the 100 machine series. Firstly there is a collision-free compact wheel-head solution with integral motor spindles and a reinforced casing for larger wheel diameters when internal grinding. A choice of 10 wheel-head variations is available to ensure the optimal machine configuration based on the components to be processed.
The second stand-out feature is the enhancement of performance parameters. A higher grinding wheel drive power increases productivity, while the Z guideway produces higher profile precision from the C axis, again enhancing precision when performing
Finally, the service-friendly machine concept is also of note. Kellenberger’s service teams were involved in the design and optimisation of the machine, which impacts on faster maintenance and service operations, while optimum accessibility of maintenance-intensive components is assured.
The Kellenberger machines feature the latest Fanuc 31i CNC controls with 19” touchscreen guidance system on an operator friendly, intuitive touchscreen panel. Among the options is the newly designed cycle programming or workpiece-related graphic programming.

Seven of Advanced Grinding Solutions’ principals are exhibiting at the forthcoming AMB show in Stuttgart (18-22 September): Bahmuller, Tschudin, Rollomatic, Magnetfinish, Gerber, Platit and HandlingTech.
Bahmuller produces internal and external cylindrical grinding machines for manufacturing precision components used in the fuel-injection and turbocharger industries. One of Bahmuller’s largest end users is Delphi Technologies, which produces diesel injector systems for heavy-duty truck applications at its manufacturing centre in Gloucestershire.
Tschudin has chosen the AMB show as the worldwide premier appearance of its 350 Cube centerless grinding machine. The Tschudin Cube is thought to be the world’s smallest centerless grinding machine with a footprint of just 1500 x 1500 x 1500 mm, and is designed to grind small components from 1 to 20 mm in diameter for the automotive and medical industries.
Since starting working with Rollomatic last summer, AGS has reported major sales to cutting tool and medical component manufacturers in the UK and Ireland. In fact, Rollomatic continues to enjoy record machine sales of its range of blank preparation and five- and six-axis tool-grinding machines.
AGS currently has several Magnetfinish machines under order for the UK and recently gave the company its biggest ever single order (in excess of £1.2m) following sales made to a UK-based automotive parts manufacturer that will take delivery of large robot-based deburring machines early next year.
Platit machines are used for the coating of cutting tools, and the company will be demonstrating its latest cost-effective machines to show how small-to-medium tool manufacturers can profit by bringing the coating of their cutters in-house.
Completing the AGS line-up at AMB will be HandlingTech, which makes loading solutions that are custom-designed for any machine tool.

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.”

When Carrickfergus-based die-casting manufacturer Ryobi Aluminium Castings required the highest levels of cleanliness in the production of a vehicle oil pan for an international luxury vehicle manufacturer, it turned to MecWash for help.
MecWash provided two Solo machines and a stand-alone vacuum chamber to clean and dry the oil pan product. Working with MecWash’s in-house chemist and laboratory, the company also ensured the detergents used in the process matched requirements. The success of the solution meant Ryobi has since invested in two further systems.
