The need to continue a high level of control over the machining quality of a range of components used in the manufacture of high integrity heat transfer and specialist pressure equipment was the driving force for the installation by Graham Hart (Process Technology) Ltd of a Hankook vertical boring and turning machine (VTL).

Supplied by T W Ward CNC Machinery (Ward CNC), the exclusive UK distributor for the Korean machine tool manufacturer, the Hankook VTC-160/E has certainly achieved that aim, says Managing Director Chris Hart, not least because of its rigidity during machining which can be attributed to its excellent build quality levels.

“We had some specific non-standard requirements that went beyond the model specification,” he says. “Ward CNC was able to accommodate these, meeting the requirements of the company’s existing class-leading, dedicated machining facilities.

“The new Hankook has a 1.8 metres table which accommodates workpieces weighing 10,000 kgs and this is ideal for some of our components, which include tube sheets.”

Used in TEMA and TEMA-type tubular heat exchangers, these units range from 100 mm shell diameters up to 50 tonnes.

A specialist in heat and mass transfer, Graham Hart (Process Technology) Ltd has, since the establishment of the company in 1973, created a comprehensive, technology-based design and manufacturing facility. This provides clients with a complete service from process design through to full equipment supply. The company is now experiencing major growth through extensive investment in new technologies and client-driven R & D.

In addition to its ISO 9001, ISO 14001 and OHSMS 18001 accreditation, the company has been approved by the American Society of Mechanical Engineers to use the ‘U’ symbol on vessels manufactured to ASME VIII Div 1.

Used in the production of a range of components for the chemical, petrochemical, pharmaceutical, food, process and nuclear/energy industries, the new VTC-160/E offers both swing and turning diameters up to 2 metres and a maximum turning height of 1.4 metres.

With a 45 kW main spindle motor and a driven tools drive offering an impressive 18.5 kW, the machine has a 24-tool station carousel offering 12 tools each for turning and milling.

“We looked at another machine of a different brand but found that not only was the Hankook of a high-quality build but that we were also more confident in Ward CNC and the overall package it offered,” adds Mr Hart.

“In addition, we have been successfully using a Ward CNC-supplied Hartford double-column machining centre since 2009, and the overall performance record of both the machine and importantly of Ward CNC was, of course, a major consideration in our decision.”
