Modular Chamfer Mill With Adjustable Bit Spacing for Thin Workpieces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chamfer mills are inadequate for efficiently chamfering thin workpieces or those with varying thicknesses, as they require fixed-size chamfer cutters that cannot adjust to different thicknesses, limiting their applicability.
Innovation Solution
An assembled chamfer mill with adjustable extension shafts and chamfer bits that allow for customizable spacing and number of bits based on workpiece thickness and shape, enabling simultaneous chamfering of multiple edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional chamfer mill uses a single chamfer bit for directly cutting, then the structure is simple, but it cannot chamfer both upper and lower edges simultaneously and is not suitable for thin workpieces
Solution Approach 1:
The chamfer mill is segmented into multiple independent chamfer bits (at least two) that can be positioned at different heights along the extension shaft. Each chamfer bit can independently chamfer different edges of the workpiece, enabling simultaneous chamfering of both upper and lower edges while maintaining a modular, manageable structure
Solution Approach 2:
The invention introduces the vertical dimension (height) as an additional parameter by arranging chamfer bits at different positions along the extension shaft. This allows multiple chamfer bits to operate at different vertical levels, enabling simultaneous chamfering of workpieces with varying thicknesses without increasing horizontal complexity
2Adaptability or versatility
If two chamfer cutters are arranged one on top of another with fixed distance, then simultaneous chamfering is possible, but the thickness is limited to a fixed size and not suitable for thin or varying thickness workpieces
Solution Approach 1:
The extension shaft is designed with adjustable length or positionability, allowing the vertical distance between chamfer bits to be dynamically changed. This enables the chamfer mill to adapt to workpieces of varying thicknesses, including thin workpieces, by adjusting the spacing between chamfer bits to match the specific workpiece dimensions
Solution Approach 2:
The invention changes the fixed parameter (distance between chamfer bits) into a variable parameter that can be adjusted according to workpiece thickness. By making the extension shaft length or position adjustable, the system can accommodate different workpiece thicknesses without requiring redesign of the entire chamfer mill

AI summary
An assembled chamfer mill (1) comprises a tool holder (10), an extension shaft (30), and chamfer bits (20) locked to two ends of the extension shaft (30). The chamfer bits (20) each have upper blades (221) and lower blades (222) for chamfering the edges of a workpiece (5) simultaneously. The length of a shaft body (31) of the extension shaft (30) may be set in various sizes. Depending on the thickness and shape of the workpiece (5), the shaft body (31) having an appropriate length is selected, so as to control the distance between the two chamfer bits (20). Another extension shaft (30) may be provided to connect a further chamber bit (20) for chamfering the edges of the workpiece (5) simultaneously.
