Segmented Shank Brazing Diamond Tool for Deep Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional diamond tools have low impact strength and limited cuttability due to a thick cutting section, which restricts their ability to penetrate deeply into cutting surfaces effectively.
Innovation Solution
A brazing bond type diamond tool with a unique shank structure, where the tip portion is thinner than the body and features a curved surface, and a brazing bond layer with diamond particles, allowing the shank body to penetrate and providing improved cuttability by maintaining a thin cutting section and increasing the specific surface area for diamond particle arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a brazing bond layer is formed on a tip portion with the same thickness as the shank body, then the cutting section thickness increases, but cuttability deteriorates
Solution Approach 1:
The shank is segmented into two distinct portions: a body portion and a tip portion. The tip portion has a smaller thickness than the body portion, allowing the cutting section to remain thin for improved cuttability while the body portion maintains sufficient thickness for structural strength and impact resistance.
Solution Approach 2:
Different portions of the shank are given different thickness characteristics to serve different functions. The tip portion is locally thinned to enable deep cutting and improved cuttability, while the body portion maintains full thickness for overall structural integrity. The brazing bond layer is applied only to the tip portion, concentrating the diamond particles where they are most needed for cutting.
2Productivity
If the cutting section thickness is reduced to improve cuttability, then deep cutting is enabled, but the structural integrity and impact strength decrease
Solution Approach 1:
The shank is divided into a body portion and a tip portion with different thicknesses. This segmentation allows the cutting section (tip portion + brazing bond layer) to be thin for improved cuttability, while the body portion maintains sufficient thickness to provide structural integrity and resist impact forces during operation.
3Quantity of substance
If a thicker brazing bond layer is used to secure more diamond particles, then the cutting section becomes thicker, but cuttability is reduced
Solution Approach 1:
The brazing bond layer is applied selectively to the tip portion of the shank rather than the entire shank body. This localized application ensures that diamond particles are concentrated where they are most needed for cutting, while keeping the overall cutting section thickness minimal for improved cuttability and deep cutting capability.
Applied Scientific Principles
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 design enhances cuttability by allowing deep cutting and reducing the probability of diamond particle separation, while maintaining structural integrity during high-speed rotation, thereby improving the tool's performance and lifespan.
Implementation Method 1
melting the metal powder to form the brazing bond
Implementation Method 2
forming a brazing bond by depositing a slurry solution of a brazing metal bond onto a substrate and dispersing diamond particles therein, followed by heating to a temperature of about 1300° C. or less

AI summary
The present disclosure provides a brazing bond type diamond tool having excellent cuttability. The diamond tool includes a shank having a body with a thickness of 2 mm or less and a tip portion formed along an edge of the body, the tip portion being thinner than the body; and a brazing bond layer formed on the tip portion of the shank to secure diamond particles having a particle size of 25 to 50 mesh with a brazing bond, wherein the brazing bond layer has a greater thickness than a difference between half the thickness of the shank body and half the thickness of the shank tip portion, such that some part of the shank body can penetrate into a surface of an object to be cut, and the tip portion of the shank has a curved surface at an end thereof.
