Key Features & Engineering Advantages
- Ultra-Rigid 400mm Wide Bed: The foundation of the machine is an extra-wide 400mm guideway span. The guide surfaces are treated with medium-frequency induction quenching, ensuring exceptional durability, wear resistance, and the ability to absorb extreme cutting forces.
- Massive 11kW Power & 105mm Bore: Engineered for heavy industry, the robust 11kW main motor maximizes power utilization for deep, strong cutting. The standard 105mm (4.13") through-hole easily accommodates and secures large-diameter bar stocks.
- Rapid Traverse & Intuitive Control: Maximizes production efficiency. The carriage is equipped with a fast-moving rapid traverse mechanism operated via an ergonomic, single-handle joystick. This centralized control drastically reduces operator fatigue and non-cutting idle time.
- Comprehensive Machining Versatility: An all-in-one rotary processing center. Readily performs internal and external cylindrical turning, taper turning, end facing, drilling, and specialized tasks like machining complex oil grooves.
- Universal Direct Threading: Effortlessly cuts various Metric, Imperial (Inch), Module, and Diametral Pitch (D.P.) threads, making it fully adaptable to diverse international engineering standards.
- Removable Gap Bed Design: The "62" series features a removable saddle gap, extending the maximum swing capacity up to 860mm (on the CA6266B model) to easily process oversized, irregular, and flat disc parts.
- Strict Heavy-Duty QA Testing: Before leaving the factory, every machine undergoes rigorous inspection procedures, including a mandatory "heavy-duty cutting test," to guarantee flawless precision stability and reliability right out of the crate.
