One of East China’s premier engineering academies has placed an order for a British-built Zenith 400 helical profile grinding machine from Rochdale-based PTG Holroyd. Valued at £1.3 million, the machine is scheduled to be shipped to China ready for installation in summer 2022.
“We are delighted to have secured this significant order for one of our Zenith 400 machines,” commented PTG Holroyd regional sales director, Mark Curran. “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 CBN grinding wheels and vitrified dressable media.”
A key feature of the Zenith 400 is the fact that it uses ‘diamond hard’ plated Cubic Boron Nitride (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.
Benefiting from an advanced control system that incorporates development and production software, and an on-board 3D CMM component scanning probe with fully automatic compensation feedback, Zenith 400 models have been designed to suit all user requirements, whether R&D, batch or mass production.
