Dual-station Vertical Turning and Grinding Machine

The dual-station vertical turning and grinding machine integrates vertical turning and grinding functions into a single machine platform. Its dual-station design allows multiple machining operations to be completed on a workpiece in a single clamping setup. The equipment is suitable for machining rotary components-such as automotive components, hydraulic parts, valve components, bearing housings, flanges, and gears-that require high roundness, dimensional accuracy, and surface quality. The dual-station vertical turning and grinding machine helps reduce equipment investment and labor costs while improving production efficiency for high-volume manufacturing. 

Product Performance

The machine's main structural castings-including the base, column, column slide, and slide block-are manufactured from high-quality HT250 gray cast iron. The optimized internal rib layout and stress-relief treatment effectively eliminate internal casting stresses, ensuring long-term structural stability. The machine adopts a dual-column design, with the bed supporting two independently driven saddle and slide assemblies, enabling simultaneous rough and finish turning operations.

The spindle features an integrated design to ensure stable dimensional accuracy and excellent surface finish. The spindle bearings utilize a dedicated grease lubrication system. Both the X and Z axes are equipped with roller linear guideways, providing high structural rigidity and load-bearing capacity. This design improves the feed system's load capability and positioning accuracy, allowing the machine to perform heavy-duty cutting with high material removal rates.

The machine comes standard with a 15-inch hydraulic chuck and a rotary hydraulic cylinder installed at the lower end of the spindle, enabling automatic workpiece clamping through the chuck or customized fixtures. The standard turret configuration includes a dual-turret setup (8 stations + 8 stations). Optional configurations include dual horizontal CNC turrets, single- or double-row horizontal tool holders, and an 8-station turret combined with a customized grinding head. A Y-axis can be added according to specific machining requirements, expanding the machine's capabilities to include milling and other combined machining operations.

The feed drive system uses ball screws with dedicated support bearings at both ends. A pre-tensioning installation process minimizes accuracy errors caused by thermal expansion of the ball screws, ensuring consistent machining precision. Both vertical and horizontal feed axes are driven automatically by servo motors, and protective covers are installed on both axes to prevent chips and cutting fluid from damaging the transmission components.

Integrated turning and grinding

The left and right turrets operate independently, allowing rough and finish turning operations to be performed simultaneously on the same workpiece. Simultaneous dual-tool cutting significantly reduces machining time for disc-shaped parts.
With a total of 16 tool stations, a wide range of turning, grooving, and threading tools can be mounted simultaneously, reducing the need for frequent tool changes when machining complex components.

Dual 8-station tool turret

After turning, the grinding head performs finish grinding on the brake disc surface to remove turning marks and achieve a uniform surface finish that meets braking friction requirements.
This eliminates the need for secondary workpiece clamping and a separate finishing grinding machine, while also reducing parallelism and runout errors caused by re-clamping.
