As a result, the stable cutting performance has an effect. •Machining efficiency is improved for high-speed,high-feed-rate rough machining by using the hard-layer with fine columnar structure. • Exhibits superior wear resistance when cutting mild steel, carbon steel, alloy steel and tool steel use with hardnesses...

Radius Mill Four Corners ASRF • Uses JP coating optimized for processing high-hardness materials, with higher layer hardness and improved oxidation resistance. • Cemented carbide material use the micro-grained carbide which is most suitable for high hardness material cutting, and the material improves wear resistance and chipping resistance. • Hardened steels (50-60HRC) : SKD11, SKD61, SKH, and SUS420 type etc. Cutting evaluation results SKDl 1 (6OHRC)C0WH!|K|8jigS Wear graph after cutting SKD11 (60HRC) SUS420S (50HRC)CDt3HKSt1SS Wear graph after cutting SUS420 type (50 HRC) Cutting tirne(rnin)...

4-corner ASRF type with diameters of 032 to 0100mm have been added to the regular product lineup, offering deep cutting capability as well as specifications greatly surpassing those of 2-corner ASR type inserts. Ay^i 0Dc (mm) Cutter diameter 4-corner specifications with a main cutting blade shape almost identical to that of conventional ASR main cutting blades. ^ With ASRF : Even for deep cutting, stable, high-performance machining with an almost constant load is possible.

I ^"YL/^hlCjq^Dj^^JPIfeRltB Processing by direct milling is also possible. Since the cutting flute do not extend to the center, there are limitations on the ramp angle and hole diameter, but as shown below, processing by direct milling without a pilot hole is possible for ramping and helical milling.

Radius Mill Four Corners ASRF 1. These conditions are for general guidance; in actual machining conditions adjust the parameters according to your actual machine and work-piece conditions. (If the over hung is 3Dc or less, the recommended cutting speed is Vc=180~200m/min; 3Dc or more 2. The thick and heavy chips are generated by using this tool. Be sure to remove them with air blow in order to avoid any breakage by blocking with chips. The recommended method is "Spindle center through" when blowing air. (Pay attention when removing chips in cavity work with the machining center <vertical type>.)...

Cautions regarding handling (1) When removing the tool from the case (package), be careful not to drop it on your foot or drop it onto the tips of your bare fingers. (2) When actually setting the inserts, be careful not to touch the cutting flute directly with your bare hands. 2. Cautions regarding mounting (1) When preparing for use, be sure that the inserts are firmly mounted in place and that they are firmly mounted on the arbor, etc. (2) If abnormal chattering occurs during use, stop the machine immediately...
