There are currently 70 TG Series machines in use around the world – and, each year, Holroyd typically receives orders to build several new TG models. The most recent order for a Holroyd TG350E has been placed by Jaguar Compressors, a division of the Xiamen East Asia Machinery Industry Company. Currently in build, and costing some £1.3 million, the machine will be shipped to Jaguar’s Xiamen-based manufacturing facility in mid 2020.
“With the ability to precision grind medium to large capacity rotors of up to 350 mm in diameter and 1795 mm in length, the TG350E model offered a versatile, high quality solution to Jaguar’s varied production requirements in producing screw compressors for a variety of applications, including precision filters, gas storage tanks and refrigerated dryers,” commented Holroyd Regional Sales Director, Steven Benn.
Holroyd TG Series machines provides high-speed and high-accuracy efficient stock removal. Considerable levels of automation mean reduced set-up time. As an additional advantage for users of Holroyd TG Series models, a significant amount of production time can be saved due to the fact that each machine’s diamond dressing discs are able to continuously dress during the semi-finish grinding cycles. By contrast, cutting tools typically require periodic regrinding – the frequency of which is determined by the materials and volumes being cut.
Designed primarily for the finish grinding of helical screw components after they have been milled to a rough or semi-finished state Holroyd TG Series machines are equally suited to prototyping and batch manufacture as they are to volume production. TG models offer production rates and accuracies to suit precise manufacturing strategies. Fully automated on-machine probing provides closed loop feedback of corrections to the dresser disc and does not require a high level of operator skill.
