Polishing Brush With Internal Flow Path For Dust Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The brush-like grinding stone's polishing performance decreases due to clogging of the linear abrasive members' tips with cutting dust during the polishing process.
Innovation Solution
A polishing brush with a holder that includes a flow path for discharging a liquid cutting agent towards the free ends of the linear abrasive members, preventing clogging by efficiently supplying and removing cutting dust.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tips of linear abrasive members are used for polishing, then polishing function is achieved, but cutting dust clogs the tips causing polishing performance to decrease
Solution Approach 1:
The harmful cutting dust is extracted and removed from the polishing zone through the flow path. The flow path is configured to discharge cutting dust generated during polishing away from the tips of the linear abrasive members, preventing accumulation and clogging that would otherwise degrade polishing performance.
Solution Approach 2:
A liquid cutting agent is introduced through the flow path to the polishing zone. The liquid cutting agent serves dual purposes: it acts as a lubricant during polishing and creates a flow that carries away cutting dust, preventing it from clogging the tips of the linear abrasive members and maintaining consistent polishing performance.
2Productivity
If liquid cutting agent is supplied to prevent clogging, then cutting dust is removed efficiently, but device complexity increases due to flow path structure
Solution Approach 1:
The flow path structure serves multiple functions simultaneously: it supplies the liquid cutting agent to the polishing zone, creates a flow to remove cutting dust, and is integrated into the holder design. This multi-functionality achieves efficient cutting dust removal while minimizing additional structural complexity.
Solution Approach 2:
The flow path is nested within the holder structure, with the liquid cutting agent flow path integrated into the existing holder geometry. This nesting approach allows the cutting agent to be supplied and dust to be removed efficiently without adding significant external complexity to the holder structure.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution maintains the polishing performance by preventing the tips of the linear abrasive members from clogging with cutting dust, ensuring consistent and effective polishing.
Implementation Method 1
the liquid cutting agent is efficiently supplied to the tips of the linear abrasive members from the flow path. Consequently, cutting dust can be flown out efficiently.

AI summary
A polishing brush (1) includes a plurality of linear abrasive members (32) each formed by hardening an aggregated yarn of inorganic filaments by a resin binder, and a holder (2) that holds the linear abrasive members (32). The linear abrasive members (32) are held by a base (31). The base (31) is secured to a spindle (25) in the holder (2). In the spindle (25), a flow path (28) for discharging a liquid cutting agent toward a side on which free ends (33) of the linear abrasive members (32) are located is provided.
