One of North America’s premier rotary screw compressor manufacturers has ordered a new TG 350E CNC rotor grinding machine from UK-based PTG Holroyd. The machine takes its place alongside a previous-generation TG 350 model that has been in reliable daily operation at the compressor rotor manufacturing facility since 2008.

Valued in excess of $1.7m, the new TG 350E rotor grinder is currently in build at PTG Holroyd’s Rochdale technology centre, from where it will ship in spring 2023. The machine will precision-grind screw rotors of up to 350 mm in diameter and 1800 mm in length, bringing even higher levels of flexibility to the company’s manufacturing strategies.

“Although we’re not able to name this North American customer, it is nonetheless rewarding to know that the positive experience gained by using one of our machines over so many years played a significant part in their decision to order a second PTG Holroyd machine,” says PTG Holroyd sales director Mark Curran.

With the PTG Holroyd TG series, advanced automation means reduced set-up time, while it is also possible to save a significant amount of production time due to the fact that each machine’s diamond dressing discs are continuously dressed during the semi-finish grinding cycles.

The TG range starts with the TG 50E, a machine designed to precision-grind components of up to 50 mm in diameter and 610 mm in length, with models offering stepped increases in capability up to the production of helical components measuring 450 mm in diameter and 2020 mm in length. Equally suited to prototyping, batch and volume production, TG machines are primarily for the finish-grinding of helical screw components such as worm screws and rotors (after milling to a rough or semi-finished state).

The Big Bang UK Young Scientists and Engineers Fair will be returning to Birmingham’s NEC next year. Taking place on 21-23 June 2023, the fair is the largest celebration of STEM subjects in the UK and is free to attend. Young people will have the opportunity to take part in hands-on activities and workshops to explore what the world of STEM has to offer. Over three days, students will also get to hear first-hand from real-life scientists and engineers about the endless possibilities and exciting careers in STEM. There will be particular focus on the environment and making the world a better place.

At last month’s UK Metal Expo exhibition at Birmingham’s NEC, Tata Steel committed its Port Talbot site in Wales to becoming accredited to ‘ResponsibleSteel’. The company is also set to adopt Science Based Targets with respect to its programme of emission reductions and net-zero aspirations. Tata Steel’s chief commercial officer, Anil Jhanji, announced the move during his keynote speech. He said: “These commitments to ResponsibleSteel and SBTi are a clear statement to the world and to our customers that we mean business. It will include decarbonising every aspect of our business.”

Scottish and Australian researchers have struck a new agreement to strengthen collaboration on modern manufacturing methods that could be adapted to shipbuilding and marine operations underway in both hemispheres. An MoU between the University of Strathclyde in Glasgow – operator of the National Manufacturing Institute Scotland – Flinders University in Adelaide and BAE Systems is key to the establishment of the advanced manufacturing research exchange. This will include exploring digital tools in shipbuilding, spanning automation, simulation and materials, as well as welding and joining technologies.
