Peripheral Wheel Abrasive Ring Segmentation for Slab Edge Finishing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current peripheral wheels for machining slab edges require multiple tools and passes to achieve high finishing quality, leading to increased time, cost, and limitations in machining complex profiles, as they leave noticeable machining lines and are not efficient in reducing these lines effectively.
Innovation Solution
A peripheral wheel with an abrasive ring composed of multiple portions with different abrasive capacities and particle sizes, arranged to simulate oscillatory motion through rotation, allowing for alternating abrasive surfaces to contact the edge, thereby reducing the need for multiple tools and passes while maintaining high finishing quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple tools with different particle sizes are used in sequence, then the finishing quality of the edge is improved, but the machining time and device complexity increase
Solution Approach 1:
The patent combines multiple abrasive surfaces with different particle sizes into a single peripheral wheel. The wheel includes a first abrasive surface with larger particles for cutting/roughing and a second abrasive surface with smaller particles for polishing/glazing, allowing both functions to be performed in one tool rather than requiring sequential tools.
Solution Approach 2:
The peripheral wheel is divided into distinct abrasive zones with different characteristics. The wheel body includes segmented abrasive surfaces that can be selectively engaged with the workpiece edge, allowing different particle sizes to be applied in sequence without changing tools.
2Manufacturing precision
If multiple tools with different particle sizes are used in sequence, then the finishing quality of the edge is improved, but the equipment investment and device complexity increase
Solution Approach 1:
The patent combines multiple abrasive surfaces with different particle sizes into a single peripheral wheel. The wheel includes a first abrasive surface with larger particles for cutting/roughing and a second abrasive surface with smaller particles for polishing/glazing, allowing both functions to be performed in one tool rather than requiring sequential tools.
Solution Approach 2:
The peripheral wheel is designed as a multi-functional tool that can perform cutting, roughing, lapping, polishing, and glazing operations. The wheel body includes multiple abrasive surfaces that can be selectively engaged with the workpiece edge, allowing a single tool to replace multiple specialized tools.
3Ease of operation
If traditional peripheral wheels machine the edge, then the machining process is simple, but noticeable machining lines remain on the edge
Solution Approach 1:
The patent ensures continuous abrasive action by providing overlapping abrasive zones on the peripheral wheel. The first and second abrasive surfaces are positioned such that both are engaged with the workpiece edge simultaneously or in continuous sequence, eliminating idle periods and ensuring continuous material removal and finishing.
Solution Approach 2:
The peripheral wheel incorporates multiple abrasive surfaces that can be dynamically engaged or disengaged from the workpiece edge. The wheel body allows selective engagement of different abrasive zones, enabling dynamic adjustment of the machining action to optimize both simplicity and quality.

AI summary
A peripheral wheel ( 10) for machining the edges of slabs, comprising an internal wheel body (1 1), to be fixed to a spindle or other machine, and an external abrasive ring (12), which is adapted to work in contact with an edge of a slab. The abrasive ring (12) is composed of at least two portions (13, 14) that have respective abrasive surfaces (15, 16) having different abrasive capacities - one polishing with respect to the other; the portions of abrasive ring (13, 14) are juxtaposed with respect to each other with surfaces (17, 18) that extend at least partly transversely with respect to the axis of rotation (X) of the peripheral wheel (10).
