A new precision gear grinding centre from PTG Holroyd hasn’t simply been designed to bring greater levels of efficiency and accuracy to the production of specialised gears and tooth forms. The new machine, called the HG350-G, is also the first from PTG Holroyd – and believed to be the first in the UK – to use Siemens’ new Sinumerik ONE future-proof CNC, the successor to the automation specialist’s 840D CNC.

Specially developed Powerstir friction stir welding (FSW) machines from UK-based Precision Technologies Group (PTG), that incorporate a 30-metre x 4-metre moving gantry, could soon redefine the way in which Europe’s leading manufacturers of railway rolling stock produce aluminium carriage bodies.

A brand-new gear grinding centre from Holroyd Precision promises to bring even higher levels of intelligence and efficiency to the production of specialised gears and tooth forms. Called the GT350, this latest machine from the Precision Technologies Group (PTG) company has been developed for one-off and batch grinding of precision spur and helical gears, worms and screws of up to 350 mm in diameter. It can also be used to precision grind compressor rotors.

UK-based Precision Technologies Group (PTG), the manufacturer of the globally acclaimed Powerstir range of friction stir welding machines, has introduced a number of dual weld-head FSW models specifically for use in the volume production of automotive battery tray floor assemblies from extruded aluminium panels.
