GTG2 Machine Achieves DIN 1







Holroyd has fought off stiff foreign competition to secure the first sale for its revolutionary new GTG2 grinding machine. The UK customer, Micro-Precision of Hemel Hempstead, is highly pleased with the machine having already achieved grinding accuracies to DIN 1 on some gear faces during the machine acceptance trials.
“We are delighted that UK industry is recognising the many qualities of the GTG2 so soon after its launch,” commented Holroyd Sales Director Paul Hannah. “Micro-Precision is a leader in its specialist fields, and for the company to choose a Holroyd machine against the more established competitors in the market highlights the competitive edge that the GTG2 can bring to the precision gear grinding process.”

Micro-Precision was founded in 1978; an ISO 9001-2000/AS 9100 accredited manufacturer, the company provides specialised precision components to the Civil, Military, Aerospace, Medical, and commercial markets, including Formula 1. The company has a purpose built factory accommodating some 20,000 square feet of production machine capacity, and also has non-destructive testing facilities including NADCAP and Rolls-Royce-approved Nital Etch inspection.

“We did extensive research before buying the Holroyd GTG2 machine,” said Barry Cave, Director at Micro-Precision. “We already provide gear grinding on a manual machine but were looking to improve and extend this facility to expand our business in this area. As part of our research, we visited Westland in Somerset to see German precision grinding machines in operation, and also Newcastle University, which is the UK centre for excellence in gear grinding.”

“Newcastle collaborated with Holroyd on the development of the GTG2 machine and a prototype version of the machine was tested at the University, so we were keen to solicit impressions of the machine from Professor Dieter Hoffman, Director of the Gear Centre of Excellence. His comment was that “he was absolutely delighted with the performance of the machine”.

“Subsequent to the Newcastle visit we contacted Holroyd. Their response was very good: their project team were very thorough in determining our exact requirements and came back with a competitive quotation for a total package. This included the supply of the GTG2, its complete installation and operator training. We quickly decided that this was the best package and ordered the machine.”

“Machine acceptance trials were undertaken at Holroyd and these also provided the opportunity for operator training. This was very straightforward, with the many in-built operator friendly features of the GTG2 control system. The trials went exceptionally well and before long one of our operators was actually grinding gears to DIN 1.”
