Conical Deburring Tool Guide for Uniform Resin Edge Finishing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional deburring apparatuses face difficulties in maintaining uniform deburring due to changes in the contact angle between the deburring tool and the workpiece, and are challenged by contraction, deformation, and strain of resin products.
Innovation Solution
A deburring apparatus featuring a profiling guide member with a conical-shaped profiling guide portion, allowing the deburring tool to adjust and maintain contact with the workpiece surface, ensuring consistent deburring even with changing angles and material deformations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the contact angle between the deburring tool and the workpiece changes, then the deburring tool cannot follow the workpiece and perform uniform deburring, but adjusting the orientation of the profiling guide member during processing increases device complexity and processing time
Solution Approach 1:
The profiling guide member employs a conical shape with a specific opening angle (α) at its opening edge portion. This curved geometric form allows the tool to automatically adapt to varying contact angles during processing, enabling the cutting tool to follow the workpiece contour and maintain uniform deburring without requiring complex orientation adjustment mechanisms during operation.
Solution Approach 2:
The invention changes the geometric parameter of the profiling guide member by setting a specific opening angle (α) at the opening edge portion. This parameter modification enables the tool to accommodate variations in contact angle between the deburring tool and workpiece, achieving uniform deburring through geometric design rather than dynamic adjustment mechanisms.
2Manufacturing precision
If the contact angle between the deburring tool and the workpiece changes, then uniform deburring cannot be maintained, but frequent orientation adjustments increase loss of time
Solution Approach 1:
The conical geometry of the profiling guide member with a defined opening angle enables continuous adaptation to changing contact angles throughout the processing cycle. This eliminates the need to stop and reorient the tool, allowing uniform deburring to be maintained continuously as the tool follows the workpiece contour.
Solution Approach 2:
The profiling guide member's conical shape provides inherent dynamic adaptability, allowing the tool orientation to change automatically in response to varying contact angles during processing. This dynamic geometric adaptation eliminates processing interruptions and maintains uniform deburring throughout the entire operation.
3Manufacturing precision
If conventional deburring tools are used on resin products with contraction, deformation, and strain, then uniform deburring is difficult to achieve, but using a profiling guide member with conical shape requires more complex manufacturing
Solution Approach 1:
The profiling guide member is designed with a conical shape and a specific opening angle (α) at the opening edge portion. This geometric configuration compensates for contraction, deformation, and strain in resin products, enabling the cutting tool to follow the actual workpiece contour and achieve uniform deburring despite material variations.
Solution Approach 2:
By modifying the geometric parameter of the profiling guide member (introducing a specific opening angle α at the opening edge), the tool gains the capability to accommodate material deformation and contraction in resin products, achieving uniform deburring through pre-calculated geometric compensation rather than complex adaptive mechanisms.

AI summary
Provided are a deburring tool and a deburring apparatus capable of, when the contact angle between the deburring tool and a workpiece changes, following the portions to be deburred, and thus always capable of performing uniform deburring against contraction, deformation, and strain of resin products. A deburring tool includes a nav. tool 9 in which a cutting tool 7 is inserted and fitted and that has an opening 41 exposing a blade portion of the cutting tool 7, opening edge portions 42 and 43 of the opening 41 each include a profiling guide portion 45 expanding, in the circumferential direction of the profiling guide member, in a sector shape that is centered on the center axis of the nav. tool 9, and the profiling guide portion 45 is formed to have a conical shape in side view.
