Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the standard coolant supply of the machine tool is used for grinding operations, then the coolant supply system remains simple and unchanged for conventional milling, but the coolant cannot be aligned to the grinding point effectively
Solution Approach 1:
The coolant supply device is nested within the grinding tool structure itself. The base body with engagement sections is integrated into the grinding tool, allowing the coolant delivery system to be contained within the tool holder assembly rather than requiring external modifications to the machine tool's coolant system.
Solution Approach 2:
A line unit acts as an intermediary component that connects the base body to the discharge opening. This line unit serves as a flexible conduit that bridges the coolant supply from the base body to the precise grinding point, allowing alignment without complex rigid piping modifications.
2Reliability
If complex pipe constructions are provided through grinding machines to feed coolant to the desired position, then sufficient coolant can be provided at the grinding point, but the structure becomes complex and machine-specific
Solution Approach 1:
The coolant supply system is segmented into modular components: a base body with engagement sections, a line unit with discharge opening, and integration with the grinding tool. This segmentation allows each component to perform its specific function independently while maintaining overall system reliability.
Solution Approach 2:
The base body with engagement sections is designed to be universally compatible with different grinding tools and machine tools. The engagement sections can detachably fix to various tool interfaces, making the coolant supply device adaptable across different applications without requiring machine-specific complex piping.
3Adaptability or versatility
If grinding tools are exchanged and mounted on tool-carrying work spindles of universal machine tools, then milling and grinding operations can be performed on the same machine, but the standard coolant supply cannot be aligned to the grinding point
Solution Approach 1:
The coolant supply device incorporates dynamic elements including a movable slide that can engage with grooves in the tool interface, and a spring that provides flexible positioning. These dynamic components allow the coolant discharge opening to be precisely aligned with the grinding point while accommodating variations in tool mounting positions.
Solution Approach 2:
The engagement sections with clamping elements are designed to automatically position and secure the base body when the grinding tool is mounted on the work spindle. The spring-loaded mechanism self-adjusts to ensure proper alignment of the coolant discharge opening without requiring external alignment procedures.
4Manufacturing precision
If a coolant supply device with engagement sections is used to fix the device to the work spindle, then coolant can be delivered to the grinding point, but the insertion and replacement process becomes more complex
Solution Approach 1:
The engagement sections are segmented into discrete clamping elements that can independently engage with corresponding features on the tool interface. This segmentation allows each clamping element to be activated or deactivated independently, enabling selective engagement for different tool types while maintaining ease of insertion.
Solution Approach 2:
The spring-loaded clamping mechanism replaces complex mechanical fastening systems. The spring automatically provides the necessary clamping force when the tool is inserted, eliminating the need for manual adjustment or complex locking mechanisms, thereby maintaining ease of operation while ensuring reliable coolant delivery.

AI summary
The invention relates to a grinding tool with a coolant supply device A2 for a machine tool and such a coolant supply device A2. The coolant supply device A2 for the grinding tool A3 has a base body A2b with engagement sections or bores A2a and a line unit A1 for diverting coolant to a predeterminable machining area of the grinding tool A3. A detachable fixing of the coolant supply device A2 on the shank of the grinding tool A3 is possible via a clamping device. By attaching the coolant supply device A2 to the grinding tool A3, it is possible to bleed the coolant of the machine tool from the standard cooling circuit via an additional valve device on the connection ring of the machine tool and to feed it to the grinding point in the predeterminable machining area of the grinding tool A3.
