The Tongtai THA-4000P is a Horizontal Machining Center designed for high-efficiency multi-face machining of automotive components, cast aluminum, and cast iron housings. Its high-rigidity structure and high-speed cutting capability ensure stable, accurate performance in demanding production environments.
Equipped with a high-precision B-axis indexing system and a double-wall column structure, the THA-4000P delivers excellent positioning accuracy and thermal stability for long machining cycles. An optional Automatic Pallet Changer (APC) further enhances productivity by reducing downtime, making it an ideal solution for high-volume production of small- to medium-sized complex parts.
The three-point supported machine bedprovides a high-rigidity foundation while enabling faster and easier leveling.
Combined with the X-axis staggered (high–low) guideway design, this configuration enhances structural rigidity while reducing overall weight and footprint, improving machining stability and production line layout efficiency.
The machine adopts a symmetrical double-wall column structure, which reduces asymmetric thermal deformation and maintains geometric accuracy during machining.
Integrated with a honeycomb structural design, it achieves a 25% reduction in weight and a 20% increase in rigidity compared with conventional designs, ensuring excellent machine stability and structural strength.
The THA Series is specifically optimized for cast iron and aluminum alloy machining, featuring a 15,000 rpm high-speed spindle that delivers up to 249 Nm of torque for excellent cutting responsiveness.
An optional No. 50 spindle is available, providing stable torque of up to 420 Nm to easily handle heavy-duty cutting of castings and steel materials, enabling high-efficiency machining across a wide range of materials.
