Iska high efficiency milling cutter series helps you increase productivity
“If it is combined with multiple cutting edges on each insert, this should be a very economical approach, especially considering the price of each insert.†Iscar Germany () technically responsible Mr. Kurt Brenner said. In this context, Iscar has developed a new set of tools and blades of different geometries (including new pressing processes) that are precisely combined with the blade's coordinated coating.
The results of these initiatives are well represented in the milling cutters that Iscar calls the Helistan series, which means the blade and the central circular tangent structure cutter. What is involved here is the end mill series, which, as the name suggests, consists of a tangentially clamped blade with a 8 mm long helical cutting edge. The special toolholder arrangement on the tool allows the blade to be mounted as much as possible on one diameter. For example, a 16mm diameter end mill can be fitted with 2 inserts (up to 5 inserts for larger diameters). The Helitang range includes milling cutters from 16mm to 40mm diameter). All milling products are available in wide pitch (sparse teeth) or narrow pitch (dense teeth) configurations, and all milling cutters have internal coolant channels. Due to the small size of the blade and the tangential alignment by the tool holder, the tool can have a larger core diameter of the tool body (compared to the structure of the indexable insert with the radial arrangement), thus making the tool more High stability. Kurt Brenner said: "In addition, the special shape of the tool is connected to the embedded tool holder, which improves the reliability of the clamping and avoids the tipping of the blade with a higher feed rate." Due to the spiral shape The cutting edge, which reduces the cutting force while producing soft cutting, that is to say, no obvious stepped chips are visible on the front of the cutting edge of the milling cutter (ie no chipping is formed).
Combination of two properties
Iscar also has a series of milling cutters named after Helido (to a certain extent, this series of tools can be said to be a further development or complement to the already familiar Helimill milling cutter series), which is now equipped with a double-sided rectangular cutting edge. Another range of tools. “We combined the superior performance of two milling cutters that have already been put on the market with Helido,†explains Mr. Kurt Brenner's strategy for Iscar: “More precisely, it will be equipped with a helical cutting edge and a positive cutting. The Helimill series in the front corner is integrated with the solid structure of the Mill2000 series that is most suitable for powerful milling.†Compared to Helimill, the series is thicker and there are 4 spiral cutting edges on the right side. This obviously allows for a higher feed rate and a larger depth of cut. The standard insert has a 0.8mm tip radius, and the cutting edge of this Wipergeometrie (a blade name of a specific shape) achieves excellent surface quality when machined. Iscar also noticed an increase in the life of the tool, as well as reducing the cutting force and the same tool durability that the Helido series can achieve. As a tool for the range of applications, Kurt Brenner cites the processing of steel, stainless steel and cast iron, and can be processed with very high cutting volumes. The Helido tool range offers a narrow pitch and wide pitch arrangement – ​​for milling and milling end faces, it can be used to machine bosses up to 16mm deep to 90o. It can provide 40-160mm diameter face milling cutters - right angle milling cutters. For the time being, larger sizes of milling cutters are available in the future, and it has now begun to work with users to determine larger sizes of milling cutters.
Better milling of cast iron
Iscar's newly developed coatings Al-TEC, α-TEC and DO-TEC are used for milling, especially for the processing of common cast iron varieties. Al-TEC is an AlTiN-PVD (Titanium Nitrogen Nitride-Physical Vapor Deposition) coating that, according to Iscar, can be used with significantly higher cutting speeds when machining ductile iron and alloy steels. And α-TEC is an MT-CVD coating (medium temperature chemical vapor deposition process, coating temperature is 600 ° C to 800 ° C), for this coating (combined with Al2O3 coating), Iscar recommended Higher cutting speeds are used to machine grey cast iron. However, DO-TEC is a composite coating of MT-CVD and AlTiN-PVD. Iscar believes that it is mainly characterized by medium cutting speed to process gray cast iron and ductile cast iron.
