Walter has added a trio of side- and face-milling cutters to its Xtra.tec series for groove and slot milling, as well as trimming and slitting operations. The F4053 slitting cutter is available in diameters ranging from 80 to 160 mm, and the F4153 and F4253 side and face cutters are available in diameters ranging from 80 to 200 mm and from 100 to 250 mm, respectively. All models feature four-edged indexable inserts in staggering-tooth formation with an approach angle of 90 degrees. To increase precision, the indexible inserts are peripherally ground. Models F4153 and F4253 use identical-system indexable inserts, which are interchangeable. Inserts are mounted laterally in the F4153 and tangentially in the F4253.
The cutters are suitable for virtually all cast and steel materials, and various insert geometries allow precision adjustment to the relevant application. The inserts are constructed from the company’s Tiger.tec material, which is said to provide favorable hardness-to-toughness ratios for increased machining output. Additionally, the geometries are positive, which enable soft cuts, quality surface finish and minimal stress for the machine and workholding equipment. The tool bodies’ nickel-plated surfaces facilitate chip removal and prolonged tool life, the company says.
