Rhenus Special Coolant for efficient Composite Machining

Composite machining with rhenus special coolants — up to 60% higher feed rate and four times more parts produced
State-of-the-art machining processes rely on efficient machining of composite materials. Analyses show that conventional machining processes, such as dry machining or minimal-quantity lubrication, often deliver sub-optimal quality. By contrast, the use of special coolants demonstrates significant advantages in the process, meaning it is often the superior alternative.

Improve machining quality, reduce cost of waste
The machined workpieces made from composite materials are associated with a high degree of added value. As such, poor quality components and a high level of tool wear often generate very high costs. This makes these advanced materials less competitive.
What’s more, dry machining in particular generates large amounts of fine dust, which is associated with significant health risks. The process of removing this fine dust from the machining centres involves the use of highly complex extraction and filter systems. These costs can be avoided by using coolant.
Using special coolants has a direct and positive impact on the quality of the cuts and drillings, the cost per hole, the process costs and costs of waste, as well as other key process figures.
