2. Key Features & Advantages

Integrated Deburring, Grinding & Polishing

Combines multiple surface finishing processes in one robotic workstation, reducing the need for separate manual operations and improving production workflow.

Multi-Module Processing

Supports different processing modules according to product requirements:

• Abrasive Belt Module: Deburring, flash removal, and surface grinding.

• Buffing Wheel Module: Fine polishing for improved surface appearance.

• Custom Small Belt Module: Finishing narrow areas, edges, and complex details.

• Satin Finishing Wheel Module: Surface brushing and texture finishing.

• Servo Torque Module: Optional configuration for improved control of grinding contact conditions.

Laser Deviation Correction

Detects workpiece positioning deviations and adjusts the robot's processing path to improve alignment with the actual workpiece.

Automatic Compensation

Compensates for workpiece positioning, clamping, and dimensional variations to help maintain consistent processing results.

Modular Programming

Dedicated programs and process parameters can be configured for different casting models, enabling faster changeovers and flexible multi-product production.

Anti-Collision Protection

Provides collision protection to help reduce the risk of interference involving the robot, workpiece, and processing equipment.

Optional 3D Vision Localization

Can be equipped with a 3D vision system to identify workpiece position and orientation according to application requirements.

3. Processing Capabilities

The robotic cell can integrate multiple finishing operations based on the workpiece geometry and required surface quality.

• Deburring & Flash Removal: Removes unwanted burrs and excess material from casting edges and designated areas.

• Rough Grinding: Removes prominent surface irregularities and casting marks.

• Fine Grinding: Refines the surface before polishing.

• Polishing: Uses buffing modules to achieve the required surface finish.

• Detail Finishing: Processes narrow grooves, corners, small curved surfaces, and other difficult-to-reach areas with customized small abrasive belts.

• Satin Finishing: Creates a brushed surface texture when required.

Processing modules and sequences can be customized for individual products and finishing requirements.
