Machine Tool Splash Guard Slope and Guide for Cutting Fluid Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cutting fluid in machine tools can unintentionally flow outside through gaps between the bed and splash guard, leading to inefficiencies and potential contamination.
Innovation Solution
A machine tool design featuring expandable and contractible covers with a slope portion and guiding section within the splash guard to direct cutting fluid inward, preventing it from reaching the bed and ensuring it flows into a designated collection area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If telescopic covers are arranged with sidewalls of the splash guard in abutment on end portions of the covers, then the structure is simple and compact, but cutting fluid may flow between the end portions of the covers and the sidewalls and fall outside the machine tool
Solution Approach 1:
A guiding section is introduced as an intermediary component between the slope portion and the bottom portion. This guiding section actively directs the cutting fluid that flows between the cover and sidewall toward the intended collection area, preventing harmful leakage while maintaining the simple abutment structure.
Solution Approach 2:
The cutting fluid that would otherwise be harmful by leaking outside is converted into a beneficial flow path. The slope portion and guiding section redirect this fluid toward the bottom portion for proper collection and disposal, transforming the potential harm into a controlled process.
2Object-affected harmful factors
If the splash guard is designed to surround the bed, saddle, table and covers, then cutting fluid containment is improved, but the risk of fluid flowing through unintended portions between the bed and splash guard increases
Solution Approach 1:
The splash guard is designed with different local functions: the slope portion handles fluid redirection at the cover interface, the guiding section provides localized guidance toward the bottom portion, and the bottom portion serves as the collection zone. Each portion has optimized geometry for its specific function, preventing fluid escape through unintended paths.
3Reliability
If covers are made expandable and contractible to protect moving mechanisms, then protection capability is improved, but gaps may form between covers and splash guard allowing cutting fluid to escape
Solution Approach 1:
The cover is designed to be expandable and contractible to dynamically adapt to the moving mechanisms during operation. The slope portion and guiding section work together to ensure that even when gaps form due to dynamic movement, the cutting fluid is actively redirected toward the bottom portion, maintaining containment while preserving the dynamic protection capability.

Function Achieved in This Case
Effectively prevents cutting fluid from leaking onto the bed and escaping the machine tool, maintaining a controlled environment and improving operational efficiency.
Implementation Method 1
a slope portion slanting so as to descend from the first sidewall portion in an expandable and contractible direction of the at least one cover toward an inner side of the splash guard, the slope portion being configured to enable cutting fluid flowing between the first sidewall portion and the end portion of the at least one cover to flow downward toward the inner side of the splash guard

AI summary
A machine tool has a splash guard and a guiding section. The splash guard has a first sidewall portion on which an end portion of a telescopic cover abuts, a slope portion slanting from the first sidewall portion along an expansion and contraction direction of the telescopic cover, a second sidewall portion perpendicularly extending downward from the slope portion, and a bottom portion horizontally extending from the second sidewall portion more inward than a lower end of the slope portion in the splash guard. The guiding section is disposed more inward than the lower end of the slope portion in the splash guard and configured to guide the cutting fluid falling from the slope portion, toward the bottom portion.
