DR-550B Cast Fettling CNC Machine for Small Sized Iron Castings

Product Overview

The DR-550B cast grinding robot machine, developed by Anhui Neview Automatic Technology Co., Ltd. is a single-arm, double-station robotic system specifically engineered for grinding small cast iron parts. Utilizing 8-axis linkage technology and a dual-spindle configuration, it achieves a balance of high-precision grinding and efficient production. The double-station rotary table design enables simultaneous loading/unloading and grinding operations, significantly reducing cycle time. It is ideal for post-processing tasks such as deburring and fettling of batch-produced small iron components like automotive parts and mechanical components.

Key Parameters

Core Advantages

1.  Ultimate Rigidity & High Payload Design

    Worktable and robotic arm synchronously handle payloads up to 200kg. Through reinforced reducer and arm structure, the combined rigidity exceeds 400kg. Ensures stable performance for demanding tasks like cutting and grinding large sprue/gate remnants, with tested force output exceeding 165kg.

2.  Intelligent Compensation & Flexible Grinding Technology

    Standard displacement sensor detection system automatically identifies workpiece variations and adjusts grinding paths to accommodate significant casting tolerances.

   For easily deform-able work pieces, achieves flexible contour-following grinding via current-loop, position-loop, and torque-loop control. Grinding force can be parametrically adjusted.

3.  Efficient Double-Station Operation

    Double-station rotary table design enables simultaneous loading/unloading and grinding. Combined with automatic station switching technology, productivity increases by over 30%, significantly reducing manual intervention frequency.

4.  Safety, Environmental & Easy Maintenance

    *   Double-layer enclosed panels with automatic electrical door locks and loading-area light curtain protection comply with industrial safety standards.

    *   Integrated dust extraction ports on the protective structure. Neat internal layout facilitates easy cleaning, meeting workshop 5S management requirements.

Typical Application Scenarios

*   Batch grinding of cast iron automotive parts (e.g., engine blocks, brake discs).

*   Deburring and surface polishing of small engineering machinery components.

*   Standardized post-processing of agricultural machinery parts.

Compatible Product Features

*   Small-to-medium cast iron parts weighing ≤ 200kg.

*   Structural parts (regular or complex) within dimensions of 550*H350mm.

*   Workpieces requiring high grinding precision of ±0.02mm.

Innovation Highlights

1.  8-Axis Linkage for Flexible Processing

    Compared to traditional 5-axis/4-linkage equipment, the DR-550B's 8-axis linkage structure enables continuous curved surface machining, covering over 80% of cast iron part types. Traditional 5-axis machines typically only handle around 30% of similar products.

2.  AI-Assisted Intelligent Production

    *   Integrated AI vision recognition system supports high-precision workpiece positioning, reducing fixture constraints and lowering fixture costs by over 30%.

    *   Chinese programming interface coupled with model import auto-programming function increases teaching efficiency by 50%.

Standard Configuration

*   Dual-spindle grinding system (13kW spindle motors).

*   Automatic workpiece detection and compensation system.

*   Double-layer protective steel panels with integrated dust extraction system.

*   Intelligent control system.

*   Core components: 1-year warranty, lifetime maintenance service.
