Tungsten carbide burrs with the FVK and FVKS cuts are suitable for universal use on hard glass and carbon-fibre-reinforced duroplastics. Due to its high concentricity, the FVK cut is suitable for tool machines and manual applications. It is characterized by smooth milling and produces a smooth cut edge.
The FVKS cut is suitable for use on machines and robots with high feed rates.
- Particularly suitable for GRP and CRP, also with > 40 % fibre content.
- The FVKS cut produces smooth edges and is characterized by smooth milling.
- Reduced wear on the tool drive due to impact-free work without chatter marks, thanks to the high concentricity.
Materials that can be worked:
- Fibre-reinforced plastics (GRP/CRP) with a fibre content > 40 %
- Contour milling
- Milling grooves and pockets (with FSTS)
- Drilling blind holes (with FSTS)
- Drilling with minimal burr formation (with STS)
- Milling out
- Cutting out holes
Matching tool drives:
- Flexible shaft drive
- Straight grinder
- Machine tools
Recommendations for use:
- The version with a drill cut (BS) is particularly suitable for machine and robot applications, while the version with a centre drill (ZBS) is used for manual applications. It allows secure drilling on almost all surface conditions.
- Select a burr diameter greater than the thickness of the material to be machined, to avoid impacts and chattering with the risk of damaging or breaking the tool.
- Increase the rotational speed if the tool tends to chatter.
- If necessary, reduce the rotational speed and contact pressure if melting occurs.
- If possible, use the tools on powerful drives with elastically mounted spindles to avoid vibration.
- For the cost-effective use of burrs, work with higher rotational/cutting speeds.
- Power recommendation for tool drives:
- Shank diameter of 3 mm: 75 to 300 watts
- Shank diameter of 6 mm: from 300 watts
- Please observe the rotational speed recommendations.
