The turntable  dual - workbench design enables simultaneous loading/unloading and grinding, significantly improving production efficiency. It is suitable for post - processing such as deburring and polishing of medium - large iron parts in construction machinery, automobile manufacturing and other fields.

Key Parameters

Product Overview
The GR-950B, engineered by Neview Automatic, is a single-arm, dual-station grinding system specifically designed for medium-to-large steel castings. Featuring 8-axis linkage technology and dual-spindle configuration, it delivers exceptional rigidity and precision grinding capabilities. The dual-station rotary table enables simultaneous loading/unloading and grinding operations, making it ideal for post-processing tasks such as deburring and polishing of large steel components in engineering machinery, mining equipment, and related sectors—optimized for batch processing of high-hardness, oversized steel castings.

Core Technical Advantages

1. Ultra-Strong Rigidity & Heavy Payload
   • Worktable carries 420kg payload + robotic arm handles 420kg. Reinforced reducers and arm structures achieve combined rigidity >600kg, enabling stable processing of large sprue/gate remnants (tested force >200kg).
   • Compact robust structure delivers rigidity equivalent to KUKA’s 600kg-payload robots, outperforming conventional systems. Compatible with high-alloy steel castings ≥HRC50 hardness.
2. Intelligent Compensation & Wear-Resistant System
   • Nanometer-Grade Displacement Compensation: Standard high-precision sensors automatically detect casting variations (±3mm tolerance) and adjust grinding paths.
   • Dedicated Wear-Resistant Tool Library: CBN grinding wheels and ceramic tools extend tool life 5x vs. standard tooling for high-hardness castings, reducing changeover frequency.
3. Dual-Station Heavy-Duty Efficiency
   • Dual-station rotary table synchronizes handling and grinding of large workpieces. Automatic station-switching boosts productivity by 40% vs. single-station systems.
   • Dual-spindle system concurrently mounts roughing/finishing tools, completing full processes in one setup to prevent accuracy loss from re-clamping hardened materials.
4. Triple-Layer Protection & Smart Cooling
   • Triple-layer steel guards with automatic electrical locks (IP55 rating) contain high-speed splatter during grinding.
   • Intelligent temperature-controlled high-pressure cooling automatically adjusts flow based on workpiece temperature, extending tool life 30% and enabling continuous processing of castings ≤HRC60.

Typical Application Scenarios
• Engineering Machinery: Batch grinding of large steel castings (hydraulic cylinders, heavy gearbox housings).
• Mining Equipment: Surface treatment of wear-resistant components (crusher hammers, mill liners).
• Energy Equipment: Precision grinding of high-load castings (wind turbine bases, nuclear valve bodies).

Compatible Product Specifications
• Medium-to-large steel castings ≤420kg;
• Regular/complex structural parts within Ø950×H650mm dimensions;
• High-strength, wear-resistant steel castings ≥HRC35 hardness.

Innovation Highlights

1. 8-Axis High-Rigidity Machining Technology
   • Dual pitch-axis design enables continuous heavy-duty vertical/curved surface machining—covering >90% of large steel casting types—surpassing traditional 6-axis capabilities.
2. Steel Casting-Optimized Process Package
   • Built-in material-specific parameter library (e.g., ZG40Cr, ZG35SiMn) auto-adjusts grinding force/speed/cooling to prevent surface cracks.
   • Vibration suppression algorithms dynamically adjust via torque-loop control, ensuring ±0.02mm precision during high-hardness material processing.

Standard Configuration
• Single robotic arm + dual-station rotary table;
• Dual-spindle grinding system (16.5kW spindle motors);
• Nanometer-grade error detection & compensation system;
• Intelligent temperature-controlled high-pressure cooling with centralized dust extraction.
