Cutting Tool Coolant Channel for Groove Edge Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cutting tools fail to effectively supply coolant to edge parts inside a groove, leading to rapid heating and wear due to inadequate coolant reach.
Innovation Solution
A cutting tool design where the plate member is slidable and fixed with a pressure member, incorporating a coolant supply part with a flow path and ejection port that directs coolant along the plate member to reach edge parts inside the groove, allowing for reliable fluid delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If coolant is supplied from a hose arranged outside the groove, then the cooling system is simple to implement, but the coolant cannot reach the edge part inside the groove leading to overheating and rapid wear
Solution Approach 1:
The coolant supply system is segmented into multiple ejection ports positioned at different locations. One ejection port is arranged inside the groove to directly cool the edge part, while another is positioned outside to cool the plate member. This segmentation allows coolant to be delivered precisely where needed without requiring a complex single-point delivery system.
Solution Approach 2:
The plate member serves as an intermediary medium for coolant delivery. Coolant is supplied to the plate member from outside the groove, and the plate member's thermal properties and structure enable it to conduct and distribute the coolant's cooling effect to the edge part inside the groove, effectively bridging the gap between external coolant supply and internal cooling needs.
2Stability of the object's composition
If the plate member is fixed rigidly to the tool block, then the structure is simple and stable, but the edge part cannot be adjusted to different positions relative to the groove
Solution Approach 1:
The plate member is designed with sliding capability relative to the tool block, transforming the rigid fixed connection into a dynamic adjustable connection. The plate member can slide along the tool block within a certain range, allowing the edge part to be positioned at different locations relative to the groove while maintaining stable contact through friction or light pressing force.
Solution Approach 2:
The position parameter of the plate member relative to the tool block is made variable. By allowing the plate member to slide and adjust its position, the distance and orientation between the edge part and the groove can be changed to adapt to different machining requirements, while the plate member remains stable during the cutting process.
3Temperature
If the edge part is arranged inside the groove for effective cooling, then cooling efficiency improves, but the edge part becomes inaccessible to externally supplied coolant
Solution Approach 1:
The coolant supply system is divided into multiple ejection ports: one positioned inside the groove to directly supply coolant to the edge part, and another positioned outside to supply coolant to the plate member. This segmentation overcomes the inaccessibility problem by providing dual pathways for coolant delivery.
Solution Approach 2:
The plate member acts as an intermediary that receives coolant from outside the groove and transfers the cooling effect to the edge part inside the groove. This allows indirect cooling of the edge part while maintaining simple external coolant supply infrastructure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures effective cooling of edge parts inside the groove, reducing wear and extending tool life by ensuring coolant reaches the cutting insert within the groove.
Implementation Method 1
coolant supply part (4) having a flow path (41) and an ejection port (42), and supplying coolant (C) along the plate member (2)
Implementation Method 2
edge parts can be cooled in a reliable manner... the edge parts can be cooled in a reliable manner, thereby wear of the edge parts can be suppressed

AI summary
A cutting tool 1 comprises: a plate member 2 which is provided, at a leading end thereof, edge parts 221a, 221b; a support member 3 which supports the plate member 2 so as to cause the edge parts 221a, 221b to be projected; and a coolant supply part 4 which has an ejection port 42 and which ejects, from the ejection port 42, fluid that cools the edge parts 221a, 221b. The support member 3 has a non-contact surface 34s which forms a gap 34 with respect to an outer side surface of the plate member 2. The gap 34a is opened toward a side where the edge parts 221a, 221b are provided. The ejection port 42 is arranged in the gap 34a, and the ejection port 42 ejects the fluid toward the plate member 2.
