Rotor grinder

One of Holroyd Precision’s TG 350 rotor grinding machines is set to bring even higher levels of accuracy and speed to a leading Japanese manufacturer of rotors for refrigeration compressors. The machine was shipped during July and will be installed at the compressor manufacturer’s Hiroshima facility this month. Holroyd says the machine will be used to precision-grind cast iron and stainless steel screw rotors of up to 350 mm in diameter, for use in industrial refrigeration units. As a result of the investment, the refrigeration specialist will benefit from higher levels of accuracy, speed and repeatability – primarily as a result of greater levels of automation and reduced set-up time. For example, where it can presently take the business up to 50 minutes to manufacture rotors of up to 120 mm in diameter by milling and cutting, Holroyd has been able to demonstrate a time saving of around 35 minutes.
