Table 3 The comparison of different cooling strategies [177, 178]
From: Towards Sustainable Grinding of Difficult-to-Cut Alloys—A Holistic Review and Trends
Strategies | Dry | Flood | Cryogenic | MQL |
|---|---|---|---|---|
Cooling | Poor | Good | Excellent | Moderate |
Lubrication | Poor | Excellent | Moderate | Excellent |
Metal removing efficient | Poor | Good | Good | Moderate |
Product quality | Poor | Good | Excellent | Good |
Material cost | Low | High | High | Low |
Tool cost | High | Low | Low | Low |
Cleaning cost | Low | High | Low | Moderate |
Disposal cost | Low | High | Low | Moderate |
Sustainability concerns | Poor quality, efficiency, and high tool cost due to thermal damage | Water pollution, high material, and energy consumption | High initial cost and LN2 cost | Harmful oil mist |
