In an order secured this month, and valued in excess of £1.4 million, Rochdale-based Holroyd Precision is to supply one of its advanced helical rotor and thread grinding machines to the organisation. The machine, a Holroyd TG 350E, will be delivered in early 2019 and will be used by the customer to precision-grind helical components of up to 350mm in diameter and 1,795mm in length.
“We are delighted to have secured this significant order,” comments Holroyd regional sales director, Steven Benn. “Although for commercially sensitive reasons, we cannot name the customer, it is particularly rewarding to know that in their quest to achieve the highest levels of precision in rotor manufacture, they recognised the uncompromising levels of accuracy that our technologies offer.
“As we are members of the Manchester-China Forum,” he continued, “securing this significant order also underpins our ongoing drive to strengthen ties between the city region and China.”
Holroyd’s TG series of multi-purpose grinding machines offer high levels of accuracy and efficient stock removal. The range starts with the TG 50E, a machine designed to precision grind components of up to 50mm in diameter and 610mm long, with models offering stepped increases in capability up to the production of helical components measuring 350mm in diameter and 2,020mm long.
Equally suited to prototyping, batch and volume production, TG Series machines are designed primarily for the finish grinding of helical screw components such as worm screws and rotors after they have been milled to a rough or semi-finished state. The machines offer production rates and accuracies to suit precise manufacturing strategies. Fully automated on-machine probing provides closed loop feedback of corrections to the dresser wheel and does not require a high level of operator skill.
Standard features include: a fully automated grinding wheel balancing system; powerful menu-driven touchscreen programming; on-board Holroyd 3D CMM component scanning probe; high power, high-speed grinding spindles; advanced in-process dressing systems; large diameter grinding wheels for optimum wheel life; and a maximum component diameter from 3mm to 450mm, depending on component profile.
