At VIACNC, we take customisation to the next level—engineering solutions that push the boundaries of heavy-duty machining. One of our most impressive achievements involved designing and delivering a 24-inch (610mm) hollow spindle bore on a slant bed lathe, complete with front and rear manual 4-jaw chucks. At the time it was considered the largest hollow spindle on a slant bed lathe in production worldwide.
Engineering Challenges and Solutions
Achieving a spindle bore of this size on a slant bed lathe required a completely custom approach. Our team at VIACNC developed innovative solutions to meet the unique demands of this project:
New Headstock and Spindle Design – A spindle bore of this size required a ground-up redesign of the headstock and spindle to ensure stability and precision during operation.
Custom Spindle Nose and Chucks – We engineered bespoke spindle nose components and chucks to accommodate the size and weight of the workpieces.
Specialised Bearings – Partnering with industry leaders **Timken Bearings**, we developed custom bearings capable of handling the extreme loads and forces involved in heavy-duty turning.
Proven Performance in the Oil & Gas Industry
The modified VIATURN 50 model was delivered to a customer in the UK for the manufacture of specialised pipe products for the oil & gas industry. Years later, the machine remains in full production—proof of the unmatched reliability and performance that define VIACNC machines.
This project reflects our commitment to building heavy-duty CNC lathes that not only meet but exceed customer expectations. When it comes to precision, strength, and long-term performance, VIACNC delivers solutions that last. With over 20 years of experience supplying heavy duty hollow spindle and oil country lathes VIACNC are experts in large capacity turning.
