UK-based PTG Heavy Industries has secured an order from a leading Indian manufacturing company for the supply of two of its Versa Turn hollow spindle heavy-duty lathes. The lathes will be used for a variety of machining processes, for the production of steel components of up to 12 metres in length.

Putting the customer first

PTG Heavy Industries was awarded the order not simply because of its reputation for providing high-precision manufacturing technologies, but also as a result of its willingness to produce machines of a modular design and with the flexibility to accommodate the customer’s most specific requirements.

“At PTG Heavy Industries,” comments Sales Manager, Chris Cheetham, “we always listen to the needs of customers, in order to adapt our solutions to satisfy their individual manufacturing strategies. The result is a wholly bespoke machine, developed specifically for the task in hand.”

Well recognised across industry

The advantages of using hollow spindle lathes are well recognised across a number of industrial sectors, particularly where longer material lengths need to be machined and where restrictions on floor space can limit the use of lathes with a longer machine bed.

Significant new advantages

The Versa Turn series of hollow spindle lathes from PTG Heavy Industries, however, presents manufacturers with a number of significant advantages to the hollow spindle lathe concept – each of which is helping to firmly establish the Versa Turn range as a preferred choice across sectors as wide ranging as shipbuilding, oil & gas production, power generation, aerospace, automotive and defence.

The optimal solution

“We designed the Versa Turn range to offer a modern, totally modular concept in hollow spindle lathe design,” adds Chris Cheetham. “As such,” he continues, “Versa Turn models retain a traditional flat bed configuration, something that we believe provides the optimal solution between stability, capacity and cost, yet enables us to create unique permutations for totally different manufacturing environments and applications.  For example, positioning the headstock between two bed sections enables simultaneous machining operations to take place at both ends of the lathe – something which has a dramatic effect on machine efficiencies and cycle times.”

CNC and manual operations

Equipped with full CNC control as standard, and using the customer’s preferred system, each Versa Turn lathe also meets the requirements for manual operations for turning and facing, using power-assisted Micro-Handwheel controls. The machine headstock, which is clutchless, benefits from a powerful 80kW (107hp) rated Siemens Digital AC Spindle Drive, supporting a 450mm spindle bore.

The Versa Turn hollow spindle lathe – Key benefits / options at-a-glance:

• ‘Y’ axis with +/- 100mm of travel for both first and second carriage
• Second carriage with turret and extra-wide full across saddle with extended single piece cross slide
• 150-200mm (6-8”) heavy-duty, interchangeable boring bar holder for second carriage
• Heavy-duty chip conveyor to the full-length rear of the machine
• Powered clamping of the tailstock to the machine bed
• Motorised towing pin for tailstock positioning via CNC control
• Air-conditioning unit for electrical cabinet and CNC pendant
• CNC ‘C’ axis with hydraulic disk brake for 360,000 continuous path +/- .01 degree accuracy
