ISCAR TECH TALK - Barrel-Shaped Inserts for Efficient Multi-Axis Milling

ISCAR expands the capabilities of BALLPLUS indexable endmills by introducing NEOBARREL - the new family of barrel-shaped inserts for efficient multi-axis milling. Mold-and-die shops thrive on the latest technology in tooling, software, and machines. Process success often depends on using best-in-class solutions from the past as well as from the latest advances of today. The emergence of circle segment end mill technology for full five-axis profiling is now becoming a standard for machining large diameter segments. The circle segment endmill is an effective replacement for the typical ball nose end mill that is used for semi-finishing and finishing molds. The circle segment endmill features a cutting edge that is a segment of a large diameter arc that reduces the number of stepovers and the cusp height of machining passes in the mold. The net result is a smoother surface finish and reduction of cycle times by as much as 50 to 90 percent. ISCAR's NEOBARREL insert are intended to be mounted on 16,20- and 25-mm diameter BALLPLUS endmills. The 25 mm Insert features The main cutting edge is the segment of an enlarged-radius-circle. Applying the insert significantly reduces the number of cuts and cycle time by increased stepover and stepdown operations. Diminishing the number of cuts combined with a large-radius- or arced shaped cutting edge provides high surface quality. NEOBARREL inserts are available in ISCAR's versatile IC908 grade. The new barrel-shape inserts are available in two geometry types: HCT - A cutting edge that features a combination of an arcuated taper with a ball-nose tip. The arc radius is 75 mm and the taper angle vary along the cutting edge from 34° to 46.1°, while the spherical radius of the tip is 3 mm. HLB – is a lens-shaped insert with an arcuated (oval) bottom with peripheral cutting edges. The tapered angle varies along the cutting edge from 0° to 10.5° while the nominal arc radius is 50 mm for the bottom edge, and 25 mm for the two-peripheral cutting edges. Barrel type inserts with the tapered angle vary along the cutting edge from 90°to 70°. I would like to remind you to download the ISCAR World app which features the revolutionary NEO-ITA for achieving optimal machining result. https://www.iscar.com/newarticles.aspx/countryid/1/newarticleid/2978 #ISCAR, #Milling, #BALLPLUS, #NEOBARREL, #Multi-Axis,#TECH-TALK
