Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current glass machining techniques face inefficiencies due to inadequate cooling water distribution, leading to waste, intermittent cooling, high costs, and low production efficiency, particularly in vertical machining centers using diamond special-shaped grinding wheels.
Innovation Solution
A diamond special-shaped grinding wheel with an annular grinding ring and mixed flow channels that suck in cooling water, powder, and air, forming a coating water film on the grinding wheel, and a vertical machining cooling system that uses negative pressure to improve cooling efficiency and reduce water usage, while also recovering powder and water for separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If external cooling mode is used to spray cooling water to the grinding area, then the cooling water can reach the grinding area, but most of the cooling water is thrown away from the grinding wheel working face, resulting in low utilization rate and water waste
Solution Approach 1:
The patent inverts the traditional cooling water delivery approach by using suction instead of pressure spraying. The grinding wheel rotates to draw cooling water into its structure through centrifugal force, ensuring water is delivered precisely where needed and retained during the grinding process, thereby eliminating waste and improving utilization rate
Solution Approach 2:
The cooling water delivery system is nested within the grinding wheel structure itself. The grinding wheel contains internal channels and cavities that hold cooling water, allowing the water to be transported and delivered internally rather than externally, which prevents water from being thrown away and improves both utilization and machining efficiency
2Loss of energy
If internal cooling mode is used to inject cooling water through water passing holes in the grinding wheel, then cooling water can reach the grinding area, but the water passing holes are limited in number and sparsely distributed, resulting in intermittent cooling that cannot adapt to high-speed machining
Solution Approach 1:
The grinding wheel incorporates a porous structure with numerous distributed channels throughout its body, allowing cooling water to be delivered through multiple pathways simultaneously. This dense network of channels ensures continuous cooling coverage across the entire grinding surface, enabling the system to keep pace with high-speed machining operations
Solution Approach 2:
The cooling water delivery system is segmented into multiple independent channels distributed throughout the grinding wheel structure. This segmentation allows water to flow through numerous parallel pathways, providing continuous and uniform cooling across the entire grinding surface rather than through limited sparse holes
3Object-affected harmful factors
If a closed cover is used to limit pollution from powder and cooling water, then environmental pollution is reduced, but the glass machining automation becomes complicated and requires special automated machinery for loading and unloading, increasing cost and affecting efficiency
Solution Approach 1:
The harmful powder and excess cooling water are extracted and removed from the machining area through the suction system integrated into the grinding wheel. This active removal eliminates the need for enclosed covers and complex automated handling systems, maintaining a clean machining environment while preserving automation simplicity and efficiency
