Tool Enclosure Fluid Cleaning to Prevent Chip Scattering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional machine tools are ineffective in removing machining chips from areas other than the tool tip, leading to chip scattering and contamination within the tool magazine, which can damage tools and require additional cleaning operations.
Innovation Solution
A machine tool design featuring a tool holding unit, a feed mechanism, an enclosure, and a fluid injecting nozzle that encloses the tool and injects a fluid to remove chips from the machining working portion, preventing scattering and maintaining tool magazine cleanliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the tool is enclosed in the enclosure and fluid is injected to remove chips from the machining working portion, then chip scattering is prevented and tool magazine cleanliness is maintained, but the device complexity increases
Solution Approach 1:
The invention merges the chip removal function with the existing tool enclosure structure. The enclosure that already exists for other purposes is utilized as a chip containment space, and the chip removal mechanism is integrated into this existing structure. This merging approach minimizes additional device complexity while achieving effective chip containment and removal.
Solution Approach 2:
The invention introduces a cleaning fluid as an intermediary substance to facilitate chip removal. The cleaning fluid is injected into the enclosure to loosen and remove chips from the machining working portion, and the used fluid along with dislodged chips is then evacuated. This intermediary approach enables effective chip removal without requiring direct mechanical contact that would increase device complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively removes machining chips from the machining working portion within a closed enclosure, preventing chip scattering and ensuring the tool magazine remains clean, allowing for efficient replacement of cutting tools without additional cleaning.
Implementation Method 1
a fluid injecting nozzle provided on at least one of the tool holding unit and the enclosure and injecting a fluid toward the tool enclosed in the enclosure

AI summary
A machine tool (1) removes chips adhering to a working portion of a tool (T). More specifically, a fluid injecting nozzle (23, 24) injects a fluid toward the tool (T) enclosed in an enclosure (22). A controller (15) controls a position of the tool (T) within the enclosure (22), and further controls operation of the fluid injecting nozzle (23, 24) such that the fluid is injected when the tool (T) is within the enclosure (22).
