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°.

Iscar tech talk - iscar helialu super positive polished rake inserts

ISCAR expands the HELIALU line with super positive polished rake inserts. HELIALU inserts have a new sub-micron grade which assures higher productivity for machining aluminum and non-ferrous materials under the ISO N group of applications. Metal cutting technology has progressed tremendously over the past few years. It is evident that insert wear is a critical problem in metal cutting. It not only increases the production costs but also degrades the product quality. The HELIALU line is comprised of a large range of endmills and face mills which are especially designed for machining aluminum, mainly parts for the aviation industry. Insert features • Sharp, ground cutting edge for low cutting forces and a clean cut. • Polished rake face for excellent chip flow. • Positive cutting angles. • Clamping area of the insert is ground to provide full contact with the pocket for high precision. • Suitable for effective machining of various aluminum grades such as 2024 and 7075 among other types. • HELIALU inserts can withstand high cutting and centrifugal loads. • The inserts are designed for both roughing and finishing applications. ISCAR's new HELIALU inserts show precise, safe and stable machining results capable of performing highly complicated operations with increased feed rates. ISCAR’s customers can choose tougher and harder grades to achieve increased productivity. Machining aluminum with ISCAR's hard-wear resistant sub-micron carbide grade IC08, maintains the insert’s cutting-edge sharpness for longer periods of time. This contributes greatly to stable machining and longer tool life, which enables milling aluminum and aluminum-lithium alloys at very high feed rates.

ISCAR TECH TALK- ISCAR's 3-Flute Series for Machining Aluminum and Non-Ferrous Materials

ISCAR has expanded its SOLID line with a new 3-flute series for machining aluminum and other non-ferrous materials. The new endmills are designed with a 45° flute, wiper flat on the face end, controlled land and polished flutes that provide fluent chip evacuation, a smooth cut, and superb surface finish. The tools are coated with Ta-C (Tetrahedral Amorphous Carbon) diamond like coating, also known as DLC coating. Ta-C is considered the superior type among the different DLC forms and therefore provides desirable qualities such as hardness, wear-resistance, and slickness, which significantly prolongs tool life and diminishes chip jamming. Properties that are ideal for machining non-ferrous materials are; - Aluminum and Aluminum alloys with up to 12% Si content - Copper, Bronze, Silver, Gold, and Platinum - Carbon and plastic - and Composite The new SOLID line comprises a square endmill with a sharp cutting edge, a Ball nose, and Bullnose. This unique new line is suitable for HEM toolpaths with up to a 20% stepover in roughing, semi-finishing and finishing toolpaths, and can perform a ramp-down of up to 3 degrees.

ISCAR TECH TALK -The Expansion of the HELI3MILL 390 LINE

The Expansion of the HELI3MILL 390 LINE with a New Serrated Cutting Edge Insert. A new serrated cutting-edge geometry for highly efficient rough milling. ISCAR expands its advantageous HELI3MILL 390 LINE by introducing new inserts with serrated edges. The new inserts, with a radii of 0.8mm and 3.2mm designated as HM390 TDCR 1505…FW-P, feature a super positive and sharp serrated cutting-edge geometry with polished rake surfaces which assure highly efficient milling for aluminum alloys and other non-ferrous materials (ISO N grade of application). The insert’s cutting-edge geometry splits the chips into small pieces and generates low cutting forces enabling increased feed rates for higher machining productivity. Features of the new inserts include: A sharp serrated cutting edge with a special chip former; Significantly improves chip evacuation Reduces cutting load and enables high table feed Reduces vibration Reduces heat generation Suitable for High Speed Machining (HSM) Intended for 90° milling cutters Peripherally ground insert Wide sharp-edged wiper for improved surface finish Both rake and relief surfaces are polished I would like to remind you to download the ISCAR World app which features the revolutionary NEO-ITA for achieving optimal machining results. https://www.iscar.com/newarticles.aspx/countryid/1/newarticleid/2978 #ISCAR, #Milling, #HELIMILL-390-Line, #SerratedCuttingEdgeInsert, #RoughMilling, #HighSpeedMachining, #TechTalk
