Key Parameters

Product Overview
The DR-1200R/B, engineered by Neview Automatic, is a single-arm, dual-station grinding system specifically designed for large cast iron components. Featuring 9-axis linkage technology and a dual-spindle configuration, it delivers exceptional heavy-load machining capabilities while maintaining high-precision grinding standards. The dual-station rotary table enables simultaneous loading/unloading and grinding operations, significantly boosting productivity for oversized workpieces. Ideal for post-processing tasks such as deburring and polishing of large iron parts in mining machinery, heavy equipment, and related sectors.

Core Technical Advantages

1. Heavy Payload & 9-Axis Linkage Design
   • Worktable handles 1000kg payload + robotic arm carries 300kg. Reinforced reducers and arm structures achieve combined rigidity >600kg, ensuring stable processing of large sprue/gate remnants.
   • 9-axis linkage supports complex 3D trajectory machining, accommodating cast iron parts up to Ø1.2m—tripling the processing range of traditional 5-axis systems.

2. Intelligent Error Compensation & Flexible Machining
   • Standard high-precision displacement sensors automatically detect casting variations (±3mm tolerance) and adjust grinding paths.
   • Triple closed-loop control enables compliant grinding for large deformable workpieces, eliminating over-cut defects caused by insufficient rigidity.

3. Dual-Station High-Efficiency Operation
   • Dual-station rotary table synchronizes loading/unloading and grinding of large workpieces. Integrated with automatic station-switching technology, productivity increases by 40% vs. single-station systems.
   • Dual-spindle system allows simultaneous mounting of roughing/finishing tools, completing full processes in one setup to minimize re-clamping errors.

4. Heavy-Duty Protection & Eco-Design
   • Triple-layer steel guards with automatic electrical locks (IP55 rating) effectively contain splash risks during large-part grinding.
   • High-power centralized dust extraction achieves ≥98% collection efficiency, complying with EU CE environmental standards.

Applications & Compatibility
Typical Application Scenarios
• Mining Machinery: Batch grinding of large castings (crusher hammers, grinding mill drums).
• Heavy Equipment: Surface treatment of structural components (port machinery gearboxes, construction vehicle chassis).
• Energy Equipment: Precision grinding of super-sized castings (wind turbine bases, nuclear valve bodies).

Compatible Product Specifications
• Large cast iron parts ≤1000kg;
• Oversized structural components within 1200×H650mm dimensions;
• Heavy-duty workpieces requiring grinding precision of ±0.05mm.

Innovation Highlights

1. 9-Axis Linkage for Mega-Scale Machining
   Compared to conventional 8-axis systems, the DR-1200R/B’s 9-axis linkage incorporates a pitch-axis design, enabling continuous vertical/curved surface processing. Covers >90% of large cast iron part types.

2. AI-Assisted Intelligent Production
   • Enables high-precision positioning of large workpieces, reducing fixture complexity and lowering tooling costs by 40%.
   • Direct programming import slashes complex workpiece commissioning time to 1/3 of traditional systems.
