Pivotable Grinding Spindle Sets for Adjacent Workpiece Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grinding machines face inefficiencies when grinding closely adjacent workpieces due to the mutual interference of grinding spindle sets, leading to increased programming complexity and downtime, as well as potential collisions with the workpiece spindle head or tailstock.
Innovation Solution
A grinding machine design featuring pivotable grinding spindle sets with a protective cap, allowing for closer spacing of small grinding spindles and independent movement, along with a control unit for deburring and beveling using a roof profile grinding disk, enables efficient simultaneous grinding of closely adjacent workpieces and reduces downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If two grinding spindle sets are used for simultaneous grinding of closely adjacent workpieces, then productivity is improved, but the small grinding disks cannot be moved as closely to one another as desired, resulting in regions along the workpiece that cannot be reached and increased spacing requirements
Solution Approach 1:
The small grinding spindle is made pivotable relative to the large grinding spindle, allowing dynamic repositioning of the small grinding disk during the grinding process. This enables the small grinding disks to be moved closer to one another while still accessing all regions of the workpiece, resolving the spacing limitation when using two grinding spindle sets
Solution Approach 2:
The grinding spindle set is segmented into a large grinding spindle and a small grinding spindle that can be independently positioned and pivoted. This segmentation allows each spindle to be optimized for different grinding tasks and positioned at optimal locations, enabling closer spacing while maintaining full workpiece accessibility
2Area of stationary object
If the small grinding spindle is arranged on the large grinding spindle to save space, then the space requirement remains low, but the large grinding disk can collide with the workpiece spindle head or tailstock when the small grinding disk is positioned near the center point
Solution Approach 1:
The small grinding spindle is designed to be pivotable relative to the large grinding spindle, allowing it to dynamically adjust its position and avoid collisions with the workpiece spindle head or tailstock when operating near the center point of the workpiece, while maintaining compact spacing
3Reliability
If grinding spindle sets are positioned to avoid mutual interference, then collisions are prevented, but programming complexity increases and downtime increases to manage the impeding
Solution Approach 1:
The pivotable small grinding spindle enables dynamic path planning and real-time adjustment of grinding trajectories, allowing the system to navigate around obstacles and avoid mutual interference between grinding spindle sets through intelligent control rather than complex pre-programming
Solution Approach 2:
The system incorporates feedback mechanisms that monitor the positions and movements of the grinding spindle sets in real-time, enabling automatic adjustment of grinding paths to avoid collisions and optimize the grinding sequence, thereby reducing programming complexity and downtime

AI summary
The invention relates to a grinding machine for grinding workpieces, in particular for the simultaneous grinding of two workpieces which are arranged in a tightly adjacent manner. The grinding machine comprises at least two first grinding spindles and at least two second grinding spindles which in each case have a grinding disk receptacle and are mounted pivotably via a support on the spindle block of one of the first grinding spindles, with the result that they can be pivoted about the rotational axis of the respective first grinding spindle.
