Innovative Coolants and Lubricants: The Key to Environmentally Friendly Metal Processing
Metal processing faces the challenge of making processes more sustainable and environmentally friendly. In this context, innovative coolants and lubricants play a central role. They not only help reduce environmental impacts but also improve machining quality and extend tool life.
The Importance of Coolants and Lubricants in Metal Processing
Coolants and lubricants serve several important functions in metalworking. They cool the tool and the workpiece, reduce friction between the tool and the material, and carry away the resulting chips. Traditional coolants and lubricants are often based on mineral oils and contain various additives that can be harmful to the environment and health.
A New Generation of Eco-Friendly Coolants and Lubricants
The latest generation of coolants is increasingly relying on biodegradable components and sustainable raw materials. These innovative products are characterized by the following features:
- Biodegradability of over 90%
- Reduced skin irritation and lower health risks
- Improved cooling performance with lower consumption
- Longer service life due to optimized formulations
- Lower environmental impact during disposal
Plant-Based Oils as a Basis
Innovative coolants and lubricants are increasingly based on plant oils such as rapeseed or sunflower oil. These natural raw materials offer not only ecological advantages but also technical benefits such as better lubricating properties and higher temperature resistance.
Minimum Quantity Lubrication as a Forward-Looking Technology
A particularly promising approach is Minimum Quantity Lubrication (MQL). With this technology, the coolant and lubricant is applied in very small amounts, finely atomized and targeted precisely at the machining point. The advantages include:
- Dramatically reduced consumption of coolants and lubricants
- Lower disposal costs
- Drier chips that can be recycled more easily
- Improved workplace conditions
- Reduced environmental impact
Economic Aspects of Eco-Friendly Coolants and Lubricants
Switching to innovative, environmentally friendly coolants and lubricants initially requires investments in new technologies and process adjustments. However, in the long run, this investment pays off through:
- Reduced procurement costs due to lower consumption
- Lower disposal costs
- Extended tool life
- Lower maintenance and cleaning costs
- Improved occupational safety and reduced health risks
