Revolutionizing Manufacturing with Advanced Polishing Robots: Unlocking Efficiency and Precision
Company news 2024/01/08

Grinding and polishing are crucial processes in manufacturing. Robots are increasingly used to address issues like low efficiency and high costs associated with traditional manual methods. In China, the market for these robots reached 9.61 billion RMB in 2022, with 8,752 units installed. Over the next five years, installations are expected to surpass 30,000 units, showcasing substantial growth potential.

However, challenges in precision and stability limit broader adoption compared to processes like welding, handling, and palletizing.



1. Material Inconsistency: 

Variations in raw material batches and prior processing steps result in inconsistent external dimensions, challenging precise positioning and identification of products.

2. Low Polishing Yield: 

Precision requirements and workpiece deviations make it difficult to maintain a consistent finishing effect, leading to uneven grinding and a hindered mass production yield.

3. Complex Programming: 

Diverse materials and complex shapes require numerous programming points, posing a challenge for the robot to adapt its grinding trajectory and demanding high operator skill.


4. Flexible Production Changeovers: 

Small batch, diverse production patterns necessitate universal fixtures and compatibility with different processing methods, requiring a polishing program with closed-loop control.

5. Stringent Robot Performance: 

The grinding process puts significant torque on robot joints, and environmental factors like water mist and dust challenge core capabilities such as rigidity and stability.

6. Diverse Tool Requirements: 

Complex polishing processes and varied material types require the robot to frequently change tools and consumables without compromising production efficiency.
