The NHP6350 horizontal machining center is used for machining the main reducer housing.
The final drive assembly plays a crucial role in the vehicle’s power transmission system by reducing speed and increasing torque while changing the direction of force, making it an essential component. Operating under high-speed rotation and elevated temperatures, the final drive housing must remain securely mounted to the axle housing and be sealed to prevent oil leakage. To achieve this, the flange of the final drive housing is fastened to the axle housing using multiple bolts—these bolts are installed on the axle housing, pass sequentially through both the axle housing and the flange, and are secured at their ends with nuts. For these reasons, as a foundational part of the vehicle’s chassis and components, the final drive housing integrates numerous elements of the drivetrain into a cohesive unit, maintaining their correct relative positions, enabling coordinated motion, and exhibiting characteristics such as large dimensions, complex geometry, and stringent precision requirements.
Beijing Shennaming Technology Co., Ltd. utilizes the NHP6350 horizontal machining center with linear guideways from South Korea’s DN to machine the main reducer housing, from blank to finished part.
The Dean Machine Tool NHP6350 features an integral bed structure and a stepped guideway design on the X-axis, meeting both heavy‑cutting and high‑precision machining requirements. All axes are equipped with roller‑type linear guides, with a rapid traverse feed rate of 60 m/min. The machine comes standard with a 10,000 rpm electric spindle and a spindle oil cooler, minimizing thermal errors and ensuring high‑accuracy cutting. It is equipped with a standard 40‑tool turret, with an optional 376‑tool turret available to support simultaneous tooling for multiple products. The APC (Automatic Pallet Changer) system enhances production efficiency through fast, precise pallet exchange. Additional options include automatic tool‑breakage detection, automated workpiece measurement, high‑pressure coolant delivery to the tool center, an oil‑mist collector, and spray cooling, all of which assist machining operations and boost overall productivity.
