The Holroyd HG500 is quite possibly the most versatile high-precision helical profile grinding machine of its kind.
Offering incredible flexibility, the HG500 will rough and finish-grind rotors of as little as 50 mm in diameter, right up to a maximum 510 mm in diameter and 1,500 kg in weight.
In standard configuration, the HG500 can be equipped with either a 500 mm vitrified dressable aluminium oxide grinding wheel for maximum flexibility in production strategies - or use plated CBN roughing and finishing wheels for cost-effective volume production.
Alternatively, for manufacturers who precision-grind the largest of helical components, the HG500 can be specified in vitrified-only configuration. This equips the HG500 to use a 600 mm vitrified dressable aluminium oxide grinding wheel for maximum wheel life when grinding large components.
Advanced control, integrated safety, reporting and security are assured through the use of Siemens SINUMERIK ONE CNC. A travelling grinding head, instead of a conventional grinding table, means maximum probing strategies from the onboard Renishaw OSP60 scanning probe with Sprint™ technology. Variable-frequency cooling from a high-pressure unit with wheel scrub ensures reduced coolant usage, while Intelligent, programmable eco modes minimise energy consumption.
