Dean Machine Tools (formerly “Doosan Machine Tools”) VC630 five-axis machine
In recent years, China’s oil consumption has risen, and accordingly, the country’s petroleum‑equipment machinery market has maintained an upward trajectory. On the one hand, manufacturers of petroleum‑equipment machinery are increasingly demanding high‑quality CNC machine tools; on the other hand, Doosan, bolstered by its strong sales performance in this sector, enjoys a distinct advantage in terms of overall cost‑effectiveness.
The oil production process can be broadly divided into stages such as exploration, drilling, production, transportation, and refining. Among these, the primary components used in drilling, well completion, and the production phase must be machined on machine tools. Depending on geological conditions, rock hardness, and operational requirements, drill bits are categorized into roller-cone bits and fixed‑cutting‑edge bits. For each type of drill bit, Dean Machine Tools (formerly “Doosan Machine Tools”) offers machine models with varying specifications to meet its distinct machining needs. Below, we highlight the application of Dean Machine Tools’ five‑axis VC630 machine in trial machining of drill bits for drilling equipment.

The VC 630/5AX features a robust structure, excellent vibration damping, and superior heat dissipation; its shock resistance is notably strong for its size. Its machining envelope extends to 730 mm × 500 mm, and its 630 mm‑diameter worktable sets it apart from comparable models. The machine’s advanced control system boasts a powerful 1,000‑block look-ahead capability, ensuring stable and reliable machining. Additionally, it is equipped with a high‑torque spindle delivering 12,000 rpm and 32 kW of power, enabling precision machining of materials with rough surfaces or challenging machinability. Furthermore, the spindle’s faceplate incorporates a “Big Plus” dual‑contact design, guaranteeing exceptional machining accuracy.
