Circular Sawblade Surface Channels for Precise Emulsion Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional circular sawblades face challenges in efficiently supplying a cooling-lubricating emulsion to saw teeth during high-speed cutting, particularly in industrial applications, due to imprecise application and potential instability and vibration issues caused by internal channels, which also widen the cutting channel and increase material removal costs.
Innovation Solution
The sawblade features open channels on its side areas, created by laser cutting, which guide the liquid cooling emulsion from the core blade's interior to the exterior perimeter using centrifugal force, ensuring efficient lubrication and chip removal without increasing the sawblade's width or production costs, and optionally incorporating a fluid-repellent coating and a liquid reservoir system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If internal channels are produced in the core blade to guide cooling-lubricating emulsion, then lubrication precision is improved, but production cost increases and internal stability is negatively influenced
Solution Approach 1:
The invention extracts the cooling-lubricating emulsion supply function from the internal structure of the core blade and relocates it to the peripheral region. The open channels are formed on the side area of the core blade rather than embedding complex internal channels, thereby simplifying production while achieving precise emulsion delivery to the saw teeth.
Solution Approach 2:
The invention transitions from a three-dimensional internal channel structure to a two-dimensional surface channel structure on the side area of the core blade. This dimensional reduction simplifies manufacturing while maintaining the functionality of guiding cooling-lubricating emulsion to the saw teeth.
2Measurement precision
If internal channels are produced in the core blade to guide cooling-lubricating emulsion, then lubrication precision is improved, but vibration behavior is negatively influenced
Solution Approach 1:
The invention removes the problematic internal channel structure that caused vibration issues and replaces it with surface-level open channels on the side area of the core blade. This extraction eliminates the negative impact on structural integrity while preserving the lubrication function.
3Measurement precision
If internal channels are produced in the core blade, then cooling-lubricating emulsion can be supplied to saw teeth, but cutting channel width increases and material removal costs increase
Solution Approach 1:
By moving the channel structure from internal 3D space to the 2D surface of the core blade, the invention eliminates the need for additional blade width to accommodate internal channels. The open channels on the side area do not increase the cutting channel width, thereby reducing material removal costs.
