Movable Deburring Cutter for Intersecting Bore Edges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deburring methods for intersecting bores are inefficient and costly, particularly when dealing with acute angles, as they often result in secondary burrs and require additional processing steps, making it difficult to completely remove burrs without damaging the workpiece.
Innovation Solution
A cutting tool with a movable cutting body and adjustable cutting edges, designed to rotate and translate along the bore intersection, allowing for precise engagement at varying angles and preventing damage to the workpiece surface, effectively removing burrs from intersecting bores with angles between 25° to 90°.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional deburring methods are used for intersecting bores, then the process can be carried out with standard tools, but secondary burrs are formed and additional processing steps are required
Solution Approach 1:
The cutting body is designed to be movable relative to the longitudinal axis, allowing dynamic adjustment of the cutting edge position and angle during the deburring process. This enables the cutting edge to adapt to varying edge angles (15° to 165°) and maintain optimal cutting conditions throughout the spatial curve of the intersecting bore edge, preventing secondary burr formation while ensuring complete burr removal
2Adaptability or versatility
If milling processes are used for burr removal, then existing tools can be utilized, but secondary burrs are formed requiring additional operations
Solution Approach 1:
The cutting tool is designed to continuously remove burrs along the entire spatial curve of the intersecting bore edge in a single passing operation. The movable cutting body ensures continuous engagement with the edge throughout its rotation, eliminating the need for multiple discrete operations and achieving complete burr removal without secondary burr formation, thereby significantly improving productivity
3Device complexity
If conventional deburring tools are used, then standard equipment can be employed, but complete burr removal is difficult particularly at acute angles
Solution Approach 1:
The cutting body is designed to be movable relative to the longitudinal axis, allowing dynamic adjustment of the cutting edge position and angle during the deburring process. This enables the cutting edge to adapt to varying edge angles (15° to 165°) and maintain optimal cutting conditions throughout the spatial curve of the intersecting bore edge, ensuring reliable and complete burr removal even at difficult-to-access acute angles
Solution Approach 2:
The cutting edge angle α is optimized to be between 80° and 145° relative to the longitudinal axis, and the cutting body can be displaced in the direction of the longitudinal axis to adjust the engagement depth. These parameter changes enable the tool to effectively handle edges with angles between 15° and 165°, ensuring reliable burr removal across all intersection angles while maintaining a relatively simple tool structure

AI summary
The present invention relates to a cutting tool, which is designed in particular for deburring edges in cavities, such as for removing burrs from the edges of intersecting bores. The cutting tool is used in particular for deburring edges in cavities, such as for deburring intersecting bores (1, 2), especially bores (1, 2) that are inclined to each other and/or whose longitudinal axes do not have a common intersection point, and comprises a cutting holder (20) extending along a longitudinal axis (11) and a cutting body (30) arranged thereon, which has a first main cutting edge (31) whose cutting edge (32) extends at an angle α of 80° to 145° to the longitudinal axis (11), for the purpose of deburring at least one edge at a transition between intersecting bores (1, 2) at an angle of inclination ε of 25° to 90°.
