PTG Technology at the Heart of Sandvik Coromant’s New Global Deep Hole Machining Center

PTG Heavy Industries, the UK-based specialist in deep hole machining technologies, has been responsible for upgrading, installing and commissioning the deep hole drilling machine that will be used at Sandvik Coromant’s newly relocated Global Application Center for Deep Hole Machining at Halesowen in the West Midlands.

Capable of internal profiling and chamber boring, the machine has a capacity of 600mm x 2,500mm (part diameter by length) and is able to drill, from solid, holes from 10mm to 150mm in diameter, and counterbore to a maximum diameter of 300mm. It will be used to assist in customer projects and technical support, product development, application development and product and application training.

To aid the development of robust and reliable processes, the machine has been equipped with a number of sensorsfor data collection. These will be used to log critical information such as spindle torque load, coolant volume, coolant pressure, thrust and vibration – key factors in reaching decisions about process parameters and tooling.

“We are delighted to have been involved in such an exciting and important project with Sandvik Coromant,” comments PTG Heavy Industries’ Sales Manager, Christopher Cheetham.

“We were responsible for refurbishing the model in question when it was purchased by Sandvik Coromant for their original Global Application Center in Cirencester, several years ago,” he continues.  “It was, therefore, especially rewarding to have been recognised for our capabilities once again by such a leading name in deep hole machining processes, for customers across sectors as wide ranging as power generation, energy and aerospace. The relocated global facility will provide an important range of capabilities for research institutions, universities and machine tool manufacturers that wish to take part in materials cutting trials and component development.”
