SAH4035T CNC Slant-Bed Lathe: Precision, Rigidity, and Intelligence in One Compact Turning Center

In today’s high-demand manufacturing environment, precision turning machines must offer not only accuracy but also flexibility, speed, and structural rigidity. The SAH4035T CNC slant-bed lathe embodies these qualities. Designed for complex parts machining across sectors like automotive shafts, hydraulic valve housings, bearing sleeves, and aerospace fittings, it provides an ideal balance of heavy cutting performance and fine surface finish.

The machine adopts a 30° slant-bed structure, cast from HT300 high-strength iron using resin-sand casting and dual artificial aging treatment. This construction effectively reduces internal stress and deformation, ensuring consistent precision even under heavy-duty operation. The Taiwan HIWIN roller linear guideways (RGH35CA) enable smooth, high-accuracy motion with minimal friction and extended lifespan.

Powered by a 7.5 kW / 1500 rpm servo spindle motor and achieving speeds up to 4000 rpm, the SAH4035T ensures both low-speed torque and high-speed cutting capability. The A2-5 spindle nose with Φ65 mm bore diameter provides stable clamping for both steel and cast iron materials. With an 8-station turret and FANUC control system, this machine is ready for multi-process continuous machining—from turning, threading, and facing to drilling and reaming—without repositioning.

Intelligent Automation & High Accuracy

Precision is the foundation of performance. The SAH4035T achieves ±0.005 mm repeatability and ±0.008 mm positioning accuracy, supported by C3-class preloaded ball screws, P4-class bearings, and pre-tensioned drive assemblies. Its automatic lubrication system maintains optimal oil supply at every critical point, reducing wear and guaranteeing long-term stability.

The hydraulic chuck system enhances clamping efficiency, and the full-protection enclosure ensures operator safety while maintaining a clean production environment. Optional dust collection can be added for even cleaner shop conditions.

Expanding Machining Possibilities

This CNC lathe is suitable for machining a wide range of components—disc parts, small shafts, tapered parts, threaded components, and custom tool steel workpieces. Whether used for mass production or small-batch prototyping, it guarantees productivity and stability.

It also integrates seamlessly into automated production cells, supporting robotic loading/unloading and smart factory MES systems. With its compact layout (2150 × 1560 × 1560 mm) and low vibration design, it fits perfectly in high-density workshop environments.

Conclusion

As industries accelerate digital transformation, equipment like the SAH4035T plays a vital role in connecting traditional precision turning with intelligent manufacturing. Reliable, compact, and precise—it’s a machine tool that embodies the next step of smart CNC machining.
