Oscillating Deburring Tool for Non-Round Recess Edges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deburring tools struggle to effectively and safely remove burrs from non-round, intersecting bore edges, particularly those forming non-circular cuts, as they often fail to ensure even chamfering and complete removal due to the limitations of brush tools and rotating machining tools.
Innovation Solution
A deburring tool that operates in pushing and pulling modes, equipped with a spring-loaded knife that oscillates and rotates step-by-step about its longitudinal axis, allowing for precise machining of non-circular recesses without the need for edge scanning or forced guidance, and can be configured with multiple knives for comprehensive edge deburring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If brush tools are used to remove burrs, then the tool can access non-circular recesses, but the burr root cannot be removed because the bristles give way elastically
Solution Approach 1:
The patent replaces the elastic brush mechanism with a rigid knife edge that performs cutting action. The knife edge is spring-loaded to maintain contact with the workpiece surface while providing sufficient cutting force to remove burr roots, eliminating the limitation of elastic bristles that cannot penetrate or cut into the burr material effectively.
2Manufacturing precision
If rotating machining tools are used, then burrs can be removed from round recesses, but they cannot effectively machine non-circular recesses with irregular shapes
Solution Approach 1:
The patent employs a spring-loaded knife edge that dynamically adapts to the workpiece surface geometry. The spring mechanism allows the knife to maintain consistent cutting pressure while following the contours of non-circular recesses, enabling the tool to effectively machine irregular shapes that rigid rotating tools cannot accommodate.

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 tool ensures complete and smooth deburring of non-round edges by performing machining in both forward and reverse strokes, effectively addressing the challenges of intersecting bore channels and complex recess shapes, achieving a fully deburred edge without jaggedness or indentations.
Implementation Method 1
at least one knife which is movable or pivotable transversely to the longitudinal axis of the deburring tool under spring load

AI summary
The invention relates to a deburring tool for deburring edges (1, 1a, 1b), of any desired shape, of recesses in workpieces (19) using at least one cutting blade (2, 2a, 2b, 2'), wherein the deburring tool is in the form of a slotting and/or drawing tool which is rotated incrementally about its longitudinal axis and is driven displaceably in an oscillating manner in the direction of its longitudinal axis.
