Sliding Cutting Tool Coolant Interface for Leak-Free High Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing metal cutting tools with internal coolant supplies face inefficiencies in delivering high-pressure coolant to cutting edges due to leakages in gliding tube arrangements, which are not suitable for applications requiring effective cooling and chip flushing.
Innovation Solution
A sealed coolant supply system is implemented using a clamping element that presses sealing surfaces on the main tool body and slider element together, creating a sealed connection between the coolant channels, allowing for efficient high-pressure coolant delivery to the cutting edge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a gliding tube arrangement is used to supply coolant to the cutting head, then the device structure is simple and easy to assemble, but it cannot withstand high pressure coolant without leakages
Solution Approach 1:
The patent changes the pressure parameter by introducing a sealing mechanism that enables the system to withstand high pressure coolant supply. The sealing element and clamping element work together to create a pressure-resistant connection between the coolant supply line and the cutting head, allowing high pressure coolant to be delivered reliably without leakages.
2Device complexity
If the nozzle is fixed on the main tool body, then the structure is simple, but the spray has to cover a wide area and cannot focus coolant delivery to the cutting edge
Solution Approach 1:
The patent applies dynamics by making the nozzle move together with the cutting head through the sealed connection. As the cutting head moves radially to adjust the cutting depth, the nozzle follows it while maintaining a constant relative position. This dynamic arrangement ensures the coolant spray remains focused on the cutting edge throughout the adjustment range, maximizing coolant delivery efficiency.
3Adaptability or versatility
If the cutting edge position is adjusted radially, then the cutting depth can be varied, but the relative position between the nozzle and cutting edge changes causing inefficient coolant coverage
Solution Approach 1:
The patent uses the sealed connection as an intermediary mechanism that couples the nozzle to the cutting head. This sealed connection, formed by the sealing element and clamping element, ensures that the nozzle moves with the cutting head while maintaining constant relative positioning. This intermediary mechanism resolves the conflict between cutting depth adjustability and coolant application efficiency.

AI summary
A metal cutting tool includes a main tool body and a slider element received at least partially in the main tool body and arranged movably relative. The slider element has a cutting edge or supports a cutting insert having a cutting edge. An internal coolant supply is arranged to supply coolant from the main tool body to the cutting edge and has a coolant channel running within the main tool body and within the slider element. The main tool body, or a transfer element that has the coolant channel being part of the internal coolant supply and connected with the main tool body, includes a first sealing surface on which an outlet of the coolant channel of the main tool body is arranged. The slider element, or the transfer element, includes a second sealing surface on which an inlet of the coolant channel of the slider element is arranged.
