ZeniTH 400 Absolute precision in helical profile grinding Welcome to the future of helical profile grinding. Welcome to the Zenith 400 from Holroyd Precision Limited. The Holroyd name has long been a benchmark for superior, ultra-precise grinding solutions amongst screw compressor rotor manufacturers. Now, with the Zenith 400, we bring even greater levels of capability, flexibility and efficiency to your manufacturing strategies. Developed to precision grind components weighing up to 700kg, and measuring up to 420mm in diameter and 2.2 metres in length, the Zenith 400 provides exceptional versatility. In addition to being a high-precision, helical profile grinding machine, the Zenith 400 also offers high stock removal rates and aggressive semi- finishing, with production rates and accuracies tailored to your precise needs. The Zenith 400 is also the only helical profile grinding machine to offer all three grinding technologies: aluminium oxide, ‘diamond hard’ plated CBN (Cubic Boron Nitride) and vitrified, dressable CBN.

HPMS is used in the development and control of a wide range of helical profiles for screw rotors, vacuum and pump screws. Available as an additional option with the Zenith 400, HPMS can also be used to assist control of the profile during production.
