Saw Blade Alternating Axial Run-Out for Stone Cutting Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing circular saw blades for processing stone materials face challenges of high material costs, reduced cutting speed, and inaccuracy due to increased cutting thickness and deformation caused by friction, particularly in serpentine-like wound designs, and high costs in abrasion-resistant solutions.
Innovation Solution
The saw blade features alternating axial run-out areas or wobble sectors with controlled maximum deviations to enhance lateral stability and cooling, maintaining cutting speed and precision while reducing production costs through a wavy shape and energetically predetermined impacts on the side surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a serpentine-like wound shape is used to increase cutting power, then cutting power is improved, but cutting thickness increases and cutting speed decreases
Solution Approach 1:
The saw blade is divided into multiple alternating sectors (first sectors with run-out areas directed to one side, second sectors with run-out areas directed to the opposite side) around the central plane. This segmentation allows the blade to maintain a relatively flat overall structure while distributing the cutting action across different radial positions, preventing excessive cutting thickness accumulation.
Solution Approach 2:
Different sectors of the saw blade have different axial run-out characteristics, with first sectors having run-out areas directed to one side of the central plane and second sectors having run-out areas directed to the opposite side. This local variation in geometry creates alternating high and low cutting thickness zones that compensate for each other, maintaining overall cutting precision while preserving cutting speed.
2Manufacturing precision
If alternating axial run-out areas are provided to enhance lateral stability, then cutting precision is improved, but blade deformation due to friction increases
Solution Approach 1:
The saw blade features periodically alternating run-out areas that direct material removal and cooling air flow in alternating patterns around the circumference. This periodic structure ensures that heating and cooling effects are distributed uniformly across the blade, preventing localized thermal deformation while maintaining cutting precision through consistent lateral stability.
Solution Approach 2:
The run-out areas, which could be considered deviations from perfect flatness, are intentionally designed to create ventilation channels that improve cooling. The same geometric features that provide lateral stability also facilitate air flow for heat dissipation, converting what might be seen as a manufacturing tolerance issue into a beneficial cooling mechanism.
3Temperature
If ventilation areas are created for cooling, then heat dissipation is improved, but material costs increase
Solution Approach 1:
The invention modifies the geometric parameters of the saw blade by introducing controlled axial run-out variations in alternating sectors, rather than adding separate cooling components. This parameter change creates ventilation channels as an inherent feature of the blade geometry, achieving cooling functionality through design optimization rather than additional materials or complex manufacturing processes.

The solution provides precise cuts with improved lateral stability and cooling, maintaining cutting speed and reducing material costs by using a saw blade design with alternating axial run-out areas or wobble sectors, ensuring efficient and cost-effective operation.
Implementation Method 1
the axial run-out areas cause a certain ventilation effect, which ensures better cooling of the saw blade

AI summary
A circular saw blade (2), particularly for processing natural or artificial stone material, has processing elements (6) on its circumference (U), which in particular comprise diamond bodies. It is provided that at least two sectors (S) successively arranged in a circumferential direction are formed on the saw blade (2), each with a runout deviation area (B1, B2), wherein the successive runout deviation areas (B1, B2) are directed in opposite directions with respect to a central plane (E).
