Grinding Stone Fluid Injection for Waste Removal During Bearing Grinding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grinding apparatuses face inefficiencies in removing grinding wastes from the grinding stone surface during processing, leading to decreased processing efficiency and shorter grinding stone lifespan.
Innovation Solution
A grinding apparatus with a fluid injection nozzle that injects fluid at a position opposite to the processing point on the grinding stone's outer circumferential surface, using high-pressure grinding oil to blast away wastes, while sharing a common pump with the grinding oil supply apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If grinding oil is supplied only to the processing point, then the grinding process can be maintained, but grinding wastes accumulate on the grinding stone surface reducing efficiency and lifespan
Solution Approach 1:
The fluid injection system is divided into multiple injection ports positioned at different locations on the grinding stone surface. This segmentation allows targeted fluid delivery to specific areas where waste accumulation occurs, rather than relying on a single supply point
Solution Approach 2:
A fluid (grinding oil or coolant) is introduced as an intermediary substance to facilitate waste removal. The fluid acts as a mediator between the grinding stone and accumulated wastes, enabling efficient removal without direct mechanical intervention
2Object-generated harmful factors
If a separate fluid injection apparatus is added to remove grinding wastes, then waste removal efficiency improves, but device complexity increases
Solution Approach 1:
The fluid injection apparatus is merged with the existing grinding oil supply system by sharing the common pump. This integration combines waste removal functionality with the existing lubrication system, avoiding the need for a completely separate fluid delivery system
Solution Approach 2:
The common pump serves multiple functions: it supplies grinding oil for lubrication at the processing point and simultaneously provides fluid for waste removal through the injection ports. This multi-functionality reduces overall system complexity while achieving effective waste management
3Object-generated harmful factors
If multiple nozzles are added for fluid injection and grinding oil supply, then waste removal and lubrication are optimized, but space requirements and device complexity increase
Solution Approach 1:
Multiple nozzle functions (waste removal injection and grinding oil supply) are merged into a integrated system architecture. The common pump serves both functions, and the nozzles are positioned to utilize the existing grinding apparatus space efficiently
Solution Approach 2:
The injection ports are positioned on the outer circumferential surface of the grinding stone at locations different from the processing point. This spatial arrangement in another dimension (radial position) allows effective waste removal without interfering with the primary grinding operation space

AI summary
A grinding apparatus includes: a grinding stone in which an outer circumferential surface thereof is pressed against the workpiece while being rotated and driven; and a fluid injection apparatus that has a fluid injection nozzle including an injection port from which a fluid is injected to the outer circumferential surface of the grinding stone, and a grinding oil supply apparatus that supplies a grinding oil to a processing point and that includes a grinding oil supply nozzle separate from the fluid injection nozzle, the processing point being an abutting section of the grinding stone and the workpiece, wherein the injection port is arranged so as to face the outer circumferential surface of the grinding stone in a state capable of injecting the fluid to a position different from the processing point in a radial direction of the grinding stone among the outer circumferential surface of the grinding stone.
