MonsterMill FRP & FRP CR - solid carbide milling cutters for machining carbon-fibre reinforced plastics

In times of growing awareness regarding the subject of energy, energy savings and energy efficiency, the lightweight construction segment is becoming increasingly important. Composite materials are gaining larger market shares at a rapid pace.

However, outstanding material properties also present challenges for precision tool manufacturers. The extreme tensile strength and complex structure of the materials pose new challenges in terms of the tools: the high abrasiveness means tool lives of only a few metres are achieved during conventional milling.

This demand has resulted in the MonsterMill FRP milling range for machining carbon-fibre reinforced plastics, featuring an innovative geometry for optimum process security, cutting quality and performance.

MonsterMill FRP: solid carbide milling cutters featuring a special diamond coating for machining carbon-fibre reinforced plastics

The MonsterMill FRP's fine chip breakers enhance the quiet running and therefore also the component quality. The large grooves safely clear away any dust that may develop, permitting an optimal process temperature to prevent damage such as smearing on the cutting edge. A special diamond coating ensures a long tool life despite the high abrasiveness of carbon-fibre reinforced plastics.

Left-hand helix: Push cut for reducing delamination on the top side
Without helix: Neutral cut
Right-hand helix: Pulling cut for reducing delamination on the underside

Four end cutting edges provide the option of pocket milling by means of angled or circular ramping.

MonsterMill FRP CR: solid carbide milling cutter with special diamond coating and length-independent compression zone for machining carbon-fibre reinforced plastics

The patent-pending geometry of the MonsterMill FRP CR delivers compression across the entire cutting length (length-independent compression zone).

This results in:

Reduction in delamination
Prevention of projecting fibres
Increase in tool life
Multiple use option
Optimum cutting quality due to large chip flutes and excellent dust removal
Simpler and more economical programming of the machine

Available in two versions:

Two end cutting edges (fine teeth) for angled or circular ramping
One end cutting edge (coarse teeth) for angled or circular ramping

Fine-toothed with two end cutting edges

Coarse-toothed with one end cutting edge

MonsterMill FRP CR: length-independent compression

Clean cutting edges in all fibre directions

The unique geometry with regular left and right-hand cuts on each cutting element and the accompanying fibre compression across the entire cutting length result in fibres being cut off cleanly in all directions, without damaging the component.

Maximum utilisation of the cutting length

Depending on the component thickness and the fixture, you can use our MonsterMill FRP CR multiple times. You therefore receive the best cost-benefit ratio for the tool.

Example: depending on the component thickness and the fixture!

Tool life extension through oscillation

Depending on the component thickness and shape, it is possible to significantly extend the tool life of the FRP CR. The length-independent compression zone enables oscillation and thereby supports dust extraction and helps to cool the cutting edges. This is a major advantage in comparison to standard market routers with a defined compression zone.

Cutting edge cooling phase by means of oscillation

Less time and effort spent programming your machining centre

When it comes to programming, save time and money compared to conventional milling cutters that have only one compression zone.

In the case of formed components, thanks to our patent-pending length-independent compression geometry you do not have to align the milling cutter on the component.
