Iwaki, August 2020 — Tungaloy has expanded its MillQuadFeed high feed milling cutter series by adding new grades and cutter body options for its SWMT09 insert range to further extend the capabilities of high efficiency milling.
MillQuadFeed is a new generation of high feed milling cutters, offering two options of insert geometries that cover various high feed milling application needs. Versatile ZER geometry generates light cutting load at great depths of cut, enabling increased cutting depths and reduced number of machining passes. This is particularly effective to boost productivity in challenging rough milling operations of cast iron where a cutting depth can greatly vary on a single working surface. UER geometry, on the other hand, is designed to provide the cutter with small entry angle, enabling thinner chips during machining and thereby lightening the cutting load impact on the inserts’ cutting edge. UER geometry is ideal for high feed machining of exotic materials where long insert life is crucial.
Another great benefit of MillQuadFeed is its high density of inserts per diameter due to the small-sized SWMT09 inserts. Boasting seven inserts in 50 mm (2″) diameter, MillQuadFeed provides 120% higher milling efficiency than a leading competitor’s counterpart.
New to the series is the modular tooling solution: the HXSW09 modular style cutter head is available in diameters 25 mm and 32 mm. By combining with various sizes of modular shanks, the modular cutter head can be used in an optimal overhang length for every high feed milling application.
The shell mill cutter line has new diameter additions of 52 mm and 63 mm, enhancing the existing line of 40 mm and 50 mm diameter cutters. In addition to this, a new line of coarse pitch design cutters is introduced to address the needs where fewer number of teeth are wanted in contact with the work surface to minimize chatter.
Insert grades have also been expanded significantly with four new additions, including: AH3225 for steel, AH130 for stainless steel and titanium alloys, AH120 for cast iron, and AH8015 for hardened steel and Inconel, enhancing the existing versatile line of AH3135 insert grade.
