Cutting Disk Segmented Active Regions Sacrificial Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercially available cutting disks suffer from a significant loss of performance and service life due to breakage of cutting elements when colliding with hard materials like stone or metal, leading to blunting and reduced effectiveness.
Innovation Solution
The cutting disk design incorporates a second active region that radially rises or protrudes relative to the first active region, allowing sacrificial cutting elements to protect those behind them, thereby extending the service life by limiting breakage during collisions.

Engineering Contradiction Analysis
1Duration of action of moving object
If cutting elements are arranged in a single active region, then the structure is simple, but the service life is reduced due to breakage during collisions
Solution Approach 1:
The active region is segmented into a first active region and a second active region, where the second active region radially rises relative to the first. This segmentation allows cutting elements in the second active region to serve as sacrificial elements that absorb impact during collisions, protecting the cutting elements in the first active region and thereby extending the service life of the cutting disk.
2Reliability
If cutting elements are arranged radially in sequence, then protection against breakage is achieved, but the radial extent of the disk increases
Solution Approach 1:
Instead of extending protection radially outward with a large radial extent, the invention uses the axial dimension by radially rising the second active region relative to the first active region. This creates a stepped configuration where the second active region protrudes radially upward, providing protective coverage for the first active region without requiring a large overall radial extent of the disk.

AI summary
A cutting disk for a machine tool for the cutting and/or grinding of workpieces, in particular consisting of materials such as cellulose or wood, includes a disk-shaped main body that has a radially inside receiving region and a radially outside work zone. The radially outside work zone includes at least one first active region and at least one second active region. The first active region and the second active region each have at least one cutting element that is configured as a cutting grain or as a cutting tooth. The second active region rises radially or protrudes radially in relation to the first active region.
