PTG Holroyd has received an order from one of East China’s leading engineering academies for a Zenith 400 helical profile grinding machine. Valued at £1.3 million, the British-built machine is scheduled to be shipped to China ready for installation next summer.
Mark Curran, PTG Holroyd regional sales director, said: “We are delighted to have secured this significant order for one of our industry-leading Zenith 400 machines. The engineering academy specialises in the development of ultra-precise components for a number of sectors, as well as small batch production of specialised components and prototypes.
“As such, it required a machine that offered the highest levels of precision helical grinding, as well as exceptional levels of versatility. After considering machines from a number of our competitors, the Zenith 400 was chosen for its ability to meet all the helical component design, build and production needs of the academy, and for its use of twin-plated cubic boron nitride (CBN) grinding wheels and vitrified dressable media.”
Rough and finish grinding capabilityA key feature of the Zenith 400 is the fact that it uses ‘diamond hard’ plated CBN and the vitrified dressable process to provide roughing and finishing capabilities on one machine. With the advantage of twin grinding wheels, the academy staff will be able to complete both rough- and fine-grit (finish) grinding in one seamless operation.
The Zenith 400 helical profile grinder represents a new generation of grinding capability from PTG Holroyd, a company with a reputation for producing some of the world’s most accurate rotors, gears, threads and helical components.
Developed to precision-grind components weighing up to 1,000kg and measuring up to 450mm in diameter and 2.2m in length, the Zenith 400 combines high-stock removal rates and aggressive semi-finishing, with production rates and accuracies tailored to the most demanding of manufacturing strategies.
Benefitting from an advanced control system that incorporates development and production software, Zenith 400 models have been designed to suit all user requirements, whether R&D batch or mass production.
Incorporating the brands of PTG Holroyd, PTG Powerstir Friction Stir Welding and Holroyd Precision Rotors, PTG has established itself at the forefront of high-precision machine tool design, build and supply for specialised applications.
The range includes advanced machine tools for the production of complex helical components such as compressor rotors, pump screws and high-accuracy gears, and Powerstir machine tools for friction stir welding advanced alloys used in transport applications.
With production facilities in the UK, USA and China, Holroyd Precision Rotors manufactures the special-purpose, ultra-precision helical components used in a wide range of industries, including refrigeration, air-conditioning, gas and vacuum pumping, industrial air handling, aerospace, medical equipment, motion control, power transmission, power generation, oil and gas, fluid transfer and high-end automotive. PTG also provides advanced technical consulting services.
