In the fields of large-scale aerospace, wind power, railway transportation, and heavy mold processing, "large size and heavy load" and "high precision" are often a difficult contradiction to achieve simultaneously. When machining large workpieces weighing tens of tons, equipment not only needs powerful drive capabilities but also must balance high precision and long-term operational stability. The dual servo drive transmission mechanism integrates high-rigidity design and synchronous drive technology, providing more abundant torque output and more precise positioning performance.
PARKSON (PARKSON WU INDUSTRIAL CO., LTD.), leveraging decades of experience in the R&D and manufacturing of large rotary tables, has launched a groundbreaking 2000mm dual-drive ultra-heavy-duty CNC precision indexing table. Specifically designed for large floor-type milling machines, gantry milling machines, and heavy-duty automated equipment, it elevates rigidity, load-bearing capacity, and precise dynamic response to a new level!
Key Features & Technical Advantages
1. Extra-Large Table Surface & Exceptional Load Capacity
- Φ2000 large diameter disc: It adopts a high-rigidity cast base and a high-tension disc design, with radial T-slots on the surface, providing excellent clamping flexibility and strong support.
- 20,000 kg (20 tons) super load capacity: The internal high-rigidity, high-load bearing configuration can easily withstand heavy cutting and eccentric loads of large castings, large molds, or extra-long workpieces.
2. Dual Servo Motors + Dual Precision Reducers for Backlash Elimination (Dual-Drive & Zero Backlash)
- Dual-axis synchronized power drive: Equipped with dual servo motors and dual precision reduction mechanisms, the two power sources operate simultaneously to provide increased torque output and enhanced operating stability.
- Electronic/mechanical backlash suppression: Through dual-motor preloading and reverse backlash compensation control, backlash between the drive rack or gears can be effectively eliminated, achieving high-resolution micro-step positioning and zero backlash during bidirectional rotation.
3. High-Rigidity Braking & High-Precision Positioning
- Reinforced clamping brake system: Equipped with a high-pressure hydraulic clamping mechanism that provides extremely high locking torque, ensuring that the table remains firmly in position during heavy cutting while improving tool life and machined surface finish.
- High-resolution feedback: Can be equipped with a high-precision rotary encoder to maintain repeatable positioning accuracy at the arc-second level, even under long-term heavy loads and dynamic operating conditions.
