FRANKEN Fiber-Cut for Composites

Product catalog summary
Product Line Description
The Fiber-Cut product line consists of solid carbide end mills specifically designed for machining fiber-reinforced plastics like CFRP, GFRP, and AFRP. These tools feature innovative geometries and ZR high-performance coatings, with options for diamond/ZR coatings to enhance wear resistance. They are widely used in industries such as aerospace, automotive, energy, sports, and medical sectors.
Advantages
  • Delamination-free machining without fiber fraying.
  • Burr-free cutting with clean fiber separation.
  • Extended tool life due to diamond/ZR coatings.
Applications
  • Suitable for fiber-reinforced plastics (CFRP, GFRP, AFRP).
  • Used for trimming, pocketing, and continuous contour operations.
Tool Types
  • Cutting diameters range from 1-20 mm.
  • Available in various lengths and toothing types (coarse, medium, fine).
  • Options for neutral, right-hand, and left-hand helix cuts.
  • Tools with drill points are available.
Particularities
  • Conventional up-cut milling is recommended.
  • Dry machining with exhaust ventilation is advised.
  • Cutting speed varies with the plastic matrix; thermoplastics require lower speeds.
  • Feed rate affects fiber separation; excessive feed may cause delamination.
Material Description
Composites are reinforced with carbon, glass, or aramid fibers, with a plastic matrix typically made of thermosetting plastics like epoxy or polyester resin. Honeycomb sandwich panels consist of two cover skins and a honeycomb core, often made from cardboard, plastics, or aluminum.
Product Line Overview
The document provides a detailed overview of the Fiber-Cut product line, including material compatibility, toothing types, number of flutes, helix direction, coating options, diameter ranges, constructional lengths, and specific applications for each tool type. It also includes ordering examples and specifications for various tool designs.
Specifications
The document provides specifications for solid carbide end mills, specifically long design models valid for a range of products (2739F to 2747F). It emphasizes the importance of reducing the feed rate by 30% during axial machining and plunging actions via ramp or helix. The document also specifies the use of conventional up-cut milling.
Cutting Conditions
Detailed cutting conditions are provided, including cutting speeds (vc) and feed per tooth (fz) for both uncoated and TIALN coated tools. The document categorizes the suitability of these conditions for different operations.
Machining Example
A machining example is provided, detailing the tool, dimensions, and specific operations such as ramp quarter circle and pocket steps. The example includes tool clamping specifications, spindle speed, CAM system, and material details (CFRP with 60-65% carbon fiber content).
Machining Comparison
The document compares conventional tools with the FRANKEN Fiber-Cut tool, highlighting a reduction in machining time by up to 70% and optimal fiber cutting due to special tool geometry. It warns of potential delamination issues with strong fiber protrusions.
Conclusion
The document concludes with the benefits of using the specified tools, such as reduced machining time and effective roughing and finishing with a single tool. It also provides contact information for EMUGE-FRANKEN and their sales partners.
