Iscar’s indexable FFQ4 high-feed milling cutters to enhance rough milling of high-temperature alloy materials

The FFQ4 is the latest addition from ISCAR for high feed, rough milling applications. “Its design incorporates a square, single sided insert with 4 cutting edges and more flank clearance than many popular high feed solutions available,” said a company spokesperson.

Another design characteristic of the FFQ4 is a 9-degree lead angle of the cutting edge and positive rake angle position of the insert in the cutter body. All of these design characteristics add up to enhanced milling performance across a wide range of materials, especially difficult materials like austenitic stainless steel and high temperature alloys. Also, the 9-degree lead angle redirects some of the cutting forces in the axial direction, which makes for a tool that is effective when long reach is necessary.

High-feed milling has become a common milling approach used to tackle difficult-to-machine materials and applications. The FFQ4 has been designed with this in mind and to meet the demand from various industries such as aerospace, medical and oil & gas. In terms of being material specific, the FFQ4 has shown improved results when machining titanium, stainless steel (especially austenitic stainless steel), PH stainless and Inconel material grades.

Typical machining applications include heavy-duty machining with cutting tools 50mm in diameter and up on robust CAT 50, HSK 100, and HSK 125 machining centers.
