Concentric Stop Cutting Disc for Precise Pipe Cut Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting discs for pipes lack reliability and ease of use in controlling the cutting depth, often leading to damage of underlying elements and safety hazards due to off-centering and tedious installation processes.
Innovation Solution
A cutting disc with a concentrically integrated circular stop that fixes the cutting depth, ensuring precise and secure cutting by preventing off-centering, and is designed for easy installation on a lapidary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate stop is combined with the cutting disc and fixed to the rotary axis, then the cutting depth can be limited, but the stop may become off-center relative to the disc causing cutting depth errors and disc jolts
Solution Approach 1:
The stop is integrated directly into the cutting disc as a single piece, eliminating the separate stop component and its associated mounting hardware. This merging ensures the stop and disc share the same rotational center, preventing off-centering issues while maintaining reliable cutting depth limitation.
Solution Approach 2:
The problematic elements of the prior art solution (separate stop, mounting hardware, tightening mechanisms) are extracted and eliminated. Only the essential stopping function remains, integrated into the disc itself, removing the sources of off-centering and installation complexity.
2Reliability
If a separate stop with tightening mechanism is used, then the cutting depth can be limited, but the installation becomes tedious and the stop may shift during operation
Solution Approach 1:
The stop function is merged with the disc structure, eliminating separate installation steps for mounting the stop. The integrated design requires no additional tightening operations, making installation as simple as mounting the disc itself, while ensuring the stop cannot shift during operation.
Solution Approach 2:
The integrated stop automatically maintains its correct position relative to the disc during operation, requiring no user adjustment or tightening. The structure itself provides the positioning function that previously required complex mounting hardware and tightening operations.
3Adaptability or versatility
If the stop diameter is made smaller than the cutting diameter, then the cutting depth is determined, but the space between them must precisely correspond to the required cutting depth
Solution Approach 1:
The stop diameter and its position relative to the cutting diameter are predetermined during disc manufacturing with high precision. This preliminary establishment of the depth dimension eliminates the need for field adjustment and ensures accurate cutting depth control without requiring the user to perform complex measurements or adjustments.

AI summary
The present invention relates to a rotary cutting disc (1) comprising a circular stop (11) having a stop diameter (D11) concentric with the cutting diameter (D30) and smaller than the cutting diameter (D30), the stop thickness (E11) being larger than the cutting thickness (E30) so that the circular stop (11) limits the cutting depth (PC) to a predetermined value. The present invention further relates to a kit comprising several discs having different characteristics and to a method of cutting a material using such discs.
