Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water-soluble grinding fluids are ineffective in preventing grindstone clogging during superfinishing, leading to processing failures, and the use of water-insoluble fluids poses flammability risks and requires separate equipment setups.
Innovation Solution
A water-soluble cutting or grinding fluid composed of a glycol compound, an alkaline substance, and a surfactant, mixed at specific ratios, providing excellent permeability and washability, allowing for the use of a single fluid in both grinding and superfinishing processes without flammability risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a water-soluble grinding fluid is used for superfinishing, then cooling performance is improved and flammability risk is reduced, but grindstone clogging occurs and processing performance deteriorates
Solution Approach 1:
The invention changes the chemical parameters of the water-soluble fluid by adding specific additives (alkaline substance with pH 10-13, surfactant, and polymer) to modify its interaction with swarf and grindstone surface, preventing clogging while maintaining cooling properties
Solution Approach 2:
The invention creates a composite fluid system combining water-soluble base fluid with multiple functional additives (alkaline substance, surfactant, polymer) to achieve both cooling performance and anti-clogging properties that neither component could provide alone
2Reliability
If a water-insoluble grinding fluid is used for superfinishing, then grindstone clogging is prevented and processing performance is improved, but flammability risk increases and environmental friendliness deteriorates
Solution Approach 1:
The invention converts the typically harmful effect of water-soluble fluids (causing clogging) into a beneficial property by using the water-based formulation with controlled evaporation and additives that prevent swarf adhesion, thereby eliminating fire hazards while maintaining reliable processing
Solution Approach 2:
The invention modifies the chemical composition parameters of water-soluble fluids by incorporating alkaline substances and surfactants that fundamentally change the fluid's interaction with metal swarf, preventing the clogging issue that normally makes water-based fluids unsuitable for superfinishing
3Object-affected harmful factors
If conventional water-soluble grinding fluid is used for superfinishing, then flammability risk is reduced, but liquid performance is insufficient and productivity decreases
Solution Approach 1:
The invention formulates a composite water-soluble fluid containing multiple functional components (alkaline substances, surfactants, polymers) that work synergistically to provide both safety and high processing efficiency, overcoming the limitations of conventional single-component water-based fluids
