Key Parameters

Product Overview
The GR-750B, engineered by Neview Automatic, is a single-arm, dual-station grinding system specifically designed for small-to-medium steel castings. Featuring 8-axis linkage technology and a dual-spindle configuration, it delivers both high-rigidity machining 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 medium-sized steel components in engineering machinery, mining equipment, and related sectors—particularly optimized for batch processing of high-hardness steel castings.

Core Technical Advantages

1. High-Rigidity Heavy-Duty Design
   • Worktable and robotic arm synchronously handle 200kg payloads. Reinforced reducers and arm structures achieve combined rigidity >400kg, ensuring stable processing of large sprue/gate remnants on steel castings (tested force >165kg).
   • Compact and robust structure delivers rigidity equivalent to KUKA's 400kg-payload robots, far exceeding conventional robotic grinding systems. Compatible with steel castings of hardness ≥HRC45.
2. Intelligent Compensation & Wear-Resistant Processing
   • Displacement Detection & Compensation: Standard high-precision displacement sensors automatically detect casting variations (±2mm tolerance) and adjust grinding paths.
   • Wear-Resistant Tooling System: Specialized grinding wheels and wear-resistant tools extend tool life 3x vs. standard tooling for high-hardness steel castings.
3. Dual-Station High-Efficiency Operation
   • Dual-station rotary table enables simultaneous loading/unloading and grinding. Integrated with automatic station-switching technology, productivity increases by >30%.
   • Dual-spindle system allows concurrent mounting of roughing/finishing tools, completing full processes in one setup to minimize re-clamping damage on hardened materials.
4. Heavy-Duty Protection & Cooling System
   • Double-layer steel guards with automatic electrical locks effectively contain splash risks during steel casting grinding.
   • High-pressure cooling system reduces thermal impact during processing, extending tool life by 20% and ensuring machining accuracy.

Typical Application Scenarios
• Engineering Machinery: Batch grinding of medium-sized steel castings (hydraulic cylinders, gearbox housings).
• Mining Equipment: Surface treatment of wear-resistant castings and crusher components.
• Metallurgical Equipment: Deburring of high-hardness steel parts (rolls, molds).

Compatible Product Specifications
• Small-to-medium steel castings ≤200kg;
• Regular/complex structural parts within 750×H550mm dimensions;
• High-rigidity steel castings with hardness ≥HRC30.

Innovation Highlights

1. 8-Axis High-Rigidity Machining
   Compared to traditional 5-axis systems, the GR-750B’s 8-axis linkage enables continuous 3D curve machining of steel castings, covering >80% of product types—versus only ~30% compatibility for 5-axis equipment.
2. Steel Casting-Optimized Process Package
   • Customized parameter library tailors grinding force/speed for specific steel grades (e.g., ZG270-500, ZG35CrMo), preventing surface hardening.
   • Integrated vibration damping technology minimizes resonance during high-hardness material grinding, ensuring ±0.02mm machining accuracy.

Standard Configuration
• Single robotic arm + dual-station rotary table;
• Dual-spindle grinding system (16.5kW spindle motors);
• Automatic error detection & compensation system;
• High-pressure cooling and centralized dust extraction system.
