Walter USA, LLC has announced several new additions to its Walter Prototyp ConeFit modular solid carbide milling system. Prominent among these are the spade-type changeable cutting heads. These insert-like compression molded cutting heads, called "spade type" because of their double-edged, spade-like shape, are particularly suited for copy and plunge milling, chamfering, centering and spot-facing holes, as well as virtually any application where large chip clearance is needed. They are well suited for applications which require only two cutting edges, and for use with two-flute cutters.
Also new to the ConeFit line are products specially developed for graphite machining, making Walter Prototyp the only supplier currently offering a changeable head milling system for graphite machining. Its PCD coated N50 variants are available as four-flute cutters with corner radius and as a double-edged, ball-nose end mills.
The third new addition to the ConeFit system is the Proto•maxST high-performance end mill for maximum metal removal during the roughing and finishing of steel, including stainless. A four-flute variant, with and without corner radius, is now also available with ConeFit interface.
As an overall tooling system ConeFitTM combines a VHM changeable milling head with a steel toolholder. However, VHM toolholders and mono-block adaptors with HSK63, SK40 or Capto C5 and C6 are also available. The cone-shaped adapter consists of a precision cone with a patented self-centering thread. Diameters range from 3/8" to 1" (10mm - 25mm). The tooling system is universal and can be used for virtually any machining application.
