Profiled Grinding Wheel Integrating Deburring and Chamfering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grinding machines require additional deburring steps outside the main grinding process, leading to increased production time and costs due to the accumulation of burrs on workpieces, which necessitate separate deburring installations.
Innovation Solution
A grinding machine with a profiled grinding wheel and control unit that allows for deburring or chamfering of workpiece edges during or after the grinding process, using a profile section that moves in relation to the axis of rotation to mechanically remove burrs, thereby integrating deburring into the main grinding operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate deburring installations are used to remove burrs from ground workpieces, then deburring can be performed, but additional machining time, equipment cost, and production complexity increase
Solution Approach 1:
The patent combines the deburring function with the grinding machine by adding profile sections to the grinding wheel that extend beyond the grinding region. These profile sections perform deburring operations on workpiece edges during or after the grinding process, eliminating the need for separate deburring installations and reducing production time

These profile sections perform deburring operations on workpiece edges during or after the grinding process, eliminating the need for separate deburring installations and reducing production time
Solution Approach 2:
The grinding wheel is designed with multiple functions: the grinding region performs grinding operations, while the extending profile sections perform deburring and chamfering operations. This multi-functional design allows a single device to accomplish multiple machining tasks that previously required separate installations
