Glass Edge Grinding Disc Set for Wear Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machines for grinding and chamfering glass plates result in excessive wear of diamond discs, leading to rapid degradation and limited reuse, as they are designed for linear contact zones which cause uneven wear patterns.
Innovation Solution
A set of discs arranged in pairs, with specific angles and types (segment oscillating, cup, profile, and polishing discs) that separate roughing and finishing operations, using cup discs for pre-profiling and oscillating discs for excess material removal, reducing wear across all discs by distributing the workload effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional grinding machines with linear contact zones are used, then the edge grinding operation can be performed, but the diamond discs experience excessive wear and rapid degradation
Solution Approach 1:
The grinding process is divided into multiple sequential stages using different disc types: roughing discs for material removal, profiling discs for shape formation, and polishing discs for surface finishing. This segmentation distributes the workload across multiple specialized discs rather than overloading a single disc, thereby extending disc lifespan while maintaining grinding precision.
Solution Approach 2:
The roughing discs perform preliminary material removal before the workpiece enters the profiling and polishing stages. By removing excess material in advance, the subsequent profiling and polishing discs operate under reduced stress and wear conditions, extending their service life while maintaining edge quality.
2Device complexity
If single-type grinding discs are used for all operations, then the device structure is simple, but the discs degrade rapidly due to uneven wear patterns
Solution Approach 1:
Different disc types are assigned to different functional zones along the workpiece path: roughing discs at the entry zone for aggressive material removal, profiling discs in the middle zone for precise shape formation, and polishing discs at the exit zone for surface refinement. Each disc type is optimized for its specific function, distributing wear evenly across the disc set and extending overall system lifespan.
3Duration of action of moving object
If multiple disc types with different functions are implemented, then disc wear is reduced and lifespan extended, but the device complexity increases
Solution Approach 1:
Multiple functional disc types (roughing, profiling, polishing) are merged into a single integrated grinding machine structure with a common support frame and drive system. This combining approach achieves the wear-reduction benefits of specialized discs while avoiding the complexity of separate machines, as all disc types operate within one unified system.

Function Achieved in This Case
The solution slows down the wear of all grinding discs, allowing for more efficient use and longer lifespan by distributing the workload and reducing stress on individual discs, maintaining quality and automating the process of resizing glass plates.
