Milling Tools
MILLING TOOLS FOR HIGH-PERFORMANCE AND HIGH-SPEED MACHINING
High surface qualities, deep cavities, all this in materials that are difficult to machine. We have the right milling tools for a wide range of metal and plastic machining applications, from micro milling cutters with a diameter of 0.05 mm, to universal HPC milling cutters with unequal pitch, to extra-long radius milling cutters for milling graphite electrodes. Our range of milling cutters extends from universal milling cutters to special milling cutters with alternating spiralisation for fibre plastics for HSC, HCP or trochoidal milling strategies.
Milling cutter program especially for high-performance machining
Our HSC/HPC milling cutters are available in optimized variants for different materials. In addition to geometries for steels and high-strength mold construction steels up to 68 HRC, there are versions for nickel/co and titanium alloys, for aluminum as well as for plastics and fiber-reinforced materials.
All cutters in the HSC/HPC family are characterized by extra-large chip spaces and extremely stable cutting edges, with which high feed rates can be achieved.
The increase of all machining parameters with simultaneous reduction of cutting forces and high process reliability increases productivity and reduces manufacturing costs.
Reduction of production costs by increasing the metal removal rate:
The new HSC / HPC milling cutters guarantee high speeds and high chip volumes while simultaneously increasing surface quality, saving production time and reducing costly reworking processes.
The SPPW HSC / HPC high-performance milling cutter program - machining at the highest level.
"Rapid Line"
Cutting tools for innovative lightweight materials
Lightweight structures with the aim of achieving maximum weight and resource savings are and will continue to be of utmost importance in all traffic engineering systems. However, the new materials in the aircraft, automotive and boat building industries also require new processing techniques. In view of the constantly changing technological requirements, the Hessian company Spanabhebende Präzisionswerkzeuge GmbH (SPPW) is expanding its established "Rapid Line" milling cutter range to include innovative tool systems for reliable machining processes.
The new tool program offers three profiles of the toothing. A fine profile for fibre plastics with a high fibre content, a profile for soft materials with an adhesive tendency and a coarse profile for sandwich materials and foams. A further innovation are the tools which can be used especially for machining materials with aramid fibres as well as special sandwich materials, honeycomb, graphite and GFRP/CFRP materials.
The improved manufacturing process for rapid milling cutters with pyramid toothing leads to the highest manufacturing quality for fibre-reinforced materials and composites. The process combines two important characteristics: polished flutes and extremely sharp cutting edges. The pyramid-toothed cutters are equipped with multiple-edged face toothing, double-edged face toothing or a 135° drill tip.
Honeycomb composite materials with an extremely favourable weight/stiffness ratio are now widely used in lightweight construction. When machining Honeycomb structures a high surface quality with narrow manufacturing tolerances must be achieved. The structure of the plates corresponds to the honeycombs of a beehive; many hexagonal cells are covered with covering plates on the upper and lower sides. In the meantime, a wide variety of materials ranging from paper and fibre plastics to superalloys are processed in this form. The tool cuts honeycomb structures and cover plates with high surface quality in both areas. A large number of protruding cutting tips penetrate into the honeycomb and cut it. The following sharp cutting edges penetrate the honeycomb material further, shred the removed material and convey it upwards. What remains is a smooth surface that can be easily processed and connected to other WVW systems.
facts worth knowing About milling tools
Number of flutes
The right number of flutes (cutting edges) is essential for successful milling.
Soft material, as few cutting edges as possible, but large flutes. Hard material, many cutting edges, smaller chip spaces.
In addition, the more cutting edges the milling cutter has, the higher the feed rates that can be driven.

Flute Geometry
The flute removes the chip from the machining operation. If the material tends to stick, the flute should be as large as possible; for brittle-hard materials, the core thickness of the milling cutter must be greater.
Chip removal can also be improved by surface treatment, polishing or coating.

Cuttting GEOMETRY
There are particularly suitable geometries for every material. In order to get better results, features are combined:
- Spiral pitch
- cutting angle
- chip breaker
- unequal division
The geometries are particularly important when machining fibre plastics such as GRP or CFRP.

COATING
The right surface turns a good one into a top milling cutter.
Surface treatment can improve chip removal or abrasion resistance:
- polished, especially for long-chipping materials
- X.Cut coating for the processing of hard materials
- Diamond or Dia.HC for abrasive plastics or NE-Metals
