Key Features

● Reinforced Base & Table Structure: An enlarged table base with a circular guideway increases load capacity (25T–40T), enhances rotary smoothness, and improves tolerance for eccentric loads—ideal for oversized flange and ring-type workpieces.

● Precision Gear Transmission System: Features a larger main gear and optimized gear ratio (1.25–40 rpm in 16 steps), delivering higher output torque without increasing motor power. This reduces gear stress and extends the transmission system's service life.

● Reliable PLC Control System: Utilizes an OMRON programmable logic controller for stable, logic-driven operation and simplified troubleshooting, particularly beneficial for complex turret turning routines.

● Heavy-Duty Structural Design: With enlarged columns, beams, and cross-beams (models CA5250 and above), the structure offers significantly improved rigidity to handle high-force turning of large and tall components.

● Upgraded Hydraulic System: Equipped with a high-capacity oil tank to maintain stable hydraulic pressure, enabling continuous operation while minimizing system fatigue and reducing maintenance frequency.

Recommended Configurations

● Digital Display Readout (DRO): Provides real-time feedback for vertical and horizontal positioning, enhancing manual setup precision and reducing alignment errors during operation.

● Turret Head with Multi-Tool Stations: Supports efficient multi-step machining such as roughing, finishing, chamfering, and grooving without the need for re-clamping, improving cycle time and consistency.

● Heavy-Duty 4-Jaw Manual or Hydraulic Chuck: Designed to securely clamp large-diameter or irregular workpieces with high repeatability and strong holding force for heavy-duty cutting.

● Cooling and Chip Management System: Equipped with directional coolant nozzles and integrated chip trays to ensure effective heat dissipation and chip evacuation during deep or continuous cutting.

● Side Tool Holder (Optional): Provides additional flexibility for inner diameter boring, contour profiling, or other secondary machining operations in a single setup.
