rhenus special coolant for efficient composite machining

Machining composites like carbon fibre-reinforced polymers (CFRP), glass fibre-reinforced polymers (GFRP) or combined lightweight materials (stacks) is one of the most demanding tasks in production. Traditionally, these materials are handled using dry drilling and machining techniques — but often with the disadvantage of a short tool life and inadequate workpiece quality.

Overcome the challenges of efficient composite machining

The new special coolant from Rhenus Lub represents a significant upgrade over conventional dry machining processes. Improve the tool life and the quality of your workpieces.

Your advantages at a glance:

  • Reduced tool wear and tool costs
  • Increased component quality
  • Shorter production times thanks to higher cutting speed
  • Avoids delamination, less post-processing required
  • Special rinsing effect keeps machine rooms clean
  • Tested for material compatibility, no interference with the raw material

Impressive results in practice

Test runs confirm the performance of our special coolant. Achieve up to 60 percent higher feed and four times more workpieces produced.

Never machined composites before?

Simply use your existing wet-machining process.

With our rhenus XY 190 FC and rhenus XT 46 FC special coolants, you can now machine fibre-reinforced polymers such as CFRP or GFRP as well as stacks with your existing equipment and tools efficiently and easily.

Effortlessly expand your service portfolio to include the effective machining of fibre-reinforced polymers — for additional business potential and to future-proof your manufacturing process.

Absorbs fine dust, improves health and safety

rhenus XY 190 FC and rhenus XT 46 FC also set benchmarks when it comes to health and safety standards. The special coolants provide optimal absorption of potentially carcinogenic fine dust released in CFRP machining and contribute actively to protecting machine operators and machines — for maximum acceptance among process owners and for your contribution to an economical composite machining process that protects health and safety.

rhenus XT 46 FC

rhenus XT 46 FC is a water-miscible special coolant, used for efficient machining of composite materials such as carbon fibre-reinforced polymer (CFRP) and glass fibre-reinforced polymer (GFRP) as well as combined lightweight materials (stacks). It is also suitable for combined machining of workpieces made of composite materials in combination with metallic materials, such as aluminium alloys or high-strength steel grades.

Properties:

  • Very high EP addition
  • EP effect (Reichert) at 5%: 12 mm²
  • Finely dispersed opalescent
  • Very good foam degradation
  • Outstanding rinsing effect
  • High stability, good service lives
  • Boric acid-free
  • Formaldehyde-free
  • Low maintenance costs
  • Good skin compatibility
  • Pleasant smell
  • Water hazard class 1

rhenus XY 190 FC

rhenus XY 190 FC is a water-soluble, fully-synthetic special coolant, used for efficient machining of composite materials such as carbon fibre-reinforced polymer (CFRP) and glass fibre-reinforced polymer (GFRP) as well as combined lightweight materials (stacks). It is also suitable for combined machining of workpieces made of composite materials in combination with metallic materials, such as high-strength steel grades.

Properties:

  • Very high EP addition
  • EP effect (Reichert) at 5%: 14 mm²
  • Yellowish, clear
  • Very good foam degradation
  • Outstanding rinsing effect
  • High stability, good service lives
  • Boric acid-free
  • Formaldehyde-free
  • Low maintenance costs
  • Good skin compatibility
  • Pleasant smell
  • Water hazard class 1
