Zhongyou Heavy Industry VTC75 CNC Vertical Lathe Becomes Preferred Equipment for Automotive Hub & Axle Mass Production

TENGZHOU, SHANDONG – As global automotive manufacturing accelerates intelligent upgrading, Shandong Zhongyou Heavy Industry Machinery Co., Ltd. announces that its flagship VTC75 series CNC vertical lathes have achieved wide market recognition for high-precision machining of automotive core parts, including wheel hubs, axles, brake drums and brake discs, becoming a standard processing machine for dozens of domestic and overseas auto parts manufacturerszhongyoucn….

The VTC75 CNC vertical lathe is tailor-developed for medium-to-large disc and shaft auto components, with a maximum turning diameter of 750mm. Adopting integral high-rigidity gray cast iron bed and FEA optimized rib structure, the machine effectively suppresses cutting vibration under heavy rough turning loads, perfectly solving the precision instability problem during batch processing of forged steel axles and cast wheel hubs. Different from horizontal lathes, the vertical clamping layout uses workpiece self-weight to guarantee positioning concentricity, controlling radial runout within 0.02mm, which meets ultra-strict matching tolerance standards for axle and hub press assembly.

Equipped with high-torque servo spindle, 8-station automatic electric turret (optional 12-station power turret) and imported linear guide rails, the VTC75 model completes full-process rough turning, finish turning, grooving, chamfering and end face machining in a single clamping. It eliminates repeated clamping errors caused by traditional segmented processing, cutting overall production cycle by over 30% and reducing reject rate significantly. The machine supports multiple mainstream CNC systems including FANUC, Siemens and GSK, and can be matched with robotic loading/unloading mechanisms to build fully unmanned intelligent production lines for auto parts factories.

For auto hub and axle processing scenarios, Zhongyou Heavy Industry provides customized fixtures and dedicated cutting process packages. For heavy-duty truck wheel hubs and semi-trailer axles, the equipment delivers stable surface roughness Ra ≤0.8μm after finish machining; dimensional repeat positioning accuracy reaches ±0.005mm, fully satisfying the safety performance standards of commercial vehicle chassis components. Many auto parts clients report that VTC75 vertical lathes maintain consistent precision after 24-hour continuous heavy cutting operation, with lower maintenance frequency and longer service life compared with ordinary vertical lathes on the market.

Founded in 2006, Zhongyou Heavy Industry owns a 40,000㎡ modern manufacturing base and independent R&D center, holding more than 100 machine tool technical patents. All vertical lathes pass ISO9001 quality certification and strict offline precision inspection before delivery, with global after-sales service network covering Southeast Asia, Middle East, Europe and other auto manufacturing hubsen.chinazh….

“Automotive parts manufacturing puts forward dual requirements of high precision and high efficiency for metal cutting equipment,” said the technical director of Zhongyou Heavy Industry. “We continue to iterate vertical lathe products targeting hub, axle and brake parts, integrate automation and IoT real-time monitoring functions, and deliver cost-effective intelligent machining solutions to auto manufacturers worldwide.”
