Rotary Table Loading Positions for Hard Fine Machining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hard fine machining machines are not efficiently adaptable to handle varying batch sizes, requiring either specialized machines for small batches or inefficient manual handling for large batches, leading to suboptimal use of resources and increased non-productive times.
Innovation Solution
A hard fine machining machine with a rotary table that has multiple rotational positions, allowing for both manual and automatic loading/unloading, with a door to seal the machining area for manual access and an automatic system for handling workpieces in other positions, enabling flexible handling of different batch sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a hard fine machining machine is equipped with an automatic loading and unloading system for large batch sizes, then productivity is improved, but device complexity and investment costs increase
Solution Approach 1:
The rotary table is designed with dynamically reconfigurable loading and unloading stations that can be positioned at different rotational positions. The system can switch between automatic loading/unloading (for large batches) and manual loading/unloading (for small batches) by rotating the table to bring different stations into the loading position, making the device adaptable to varying production requirements
Solution Approach 2:
The loading and unloading function is segmented into multiple independent stations on the rotary table. Each station can operate independently, with some stations equipped for automatic loading/unloading and others for manual operations. This segmentation allows the system to selectively use automatic or manual stations based on batch size requirements
2Device complexity
If a hard fine machining machine is designed for manual loading and unloading, then device complexity is reduced, but productivity decreases for large batch sizes
Solution Approach 1:
The machine is designed with universal loading and unloading capability by equipping the rotary table with multiple stations that can handle both manual and automatic operations. The same machine can serve different production scenarios (small batches with manual loading, large batches with automatic loading) without requiring separate specialized machines, achieving multi-functionality
3Manufacturing precision
If specialized machines are used for different batch sizes, then manufacturing precision is maintained, but device complexity and investment costs increase
Solution Approach 1:
The rotary table enables dynamic reconfiguration of the machining system by rotating to different positions based on batch size requirements. The same precision machining system can be dynamically adapted for either manual or automatic operation modes, maintaining manufacturing precision while avoiding the need for multiple specialized machines
4Loss of time
If non-productive times are reduced for large batch sizes, then productivity is improved, but automation requirements increase device complexity
Solution Approach 1:
The automatic loading and unloading stations enable continuous operation by eliminating non-productive manual intervention times. The rotary table can continuously rotate between machining positions and automatic loading/unloading positions, maintaining continuous useful action and maximizing productivity for large batch sizes without requiring complex external automation systems

AI summary
The machine (1) has a grinding tool (4) arranged on a tool spindle (3), and a rotary table (5) with a vertically aligned rotary axis (6). A workpiece spindle (7) is arranged on the rotary table. The rotary table has a rotational position (I) in which the workpiece is machinable by the tool, and another rotational position, in which the workpiece is retained to a loading and unloading station (8). The rotary table has a third rotational position, in which the workpiece is retained to another loading and unloading station.
