A completely new range of cutters and inserts for economical face milling of stainless steel form part of a launch of products by Pramet.
\nThe versatile range includes OEHT octagonal inserts for cutting depths 4 \u2013 10 mm, alongside REHT (round) and XEHT (wiper) inserts.
\nBy utilising eight cutting edges \u2013 the highest number available for positive inserts \u2013 the new range provides an economical offer for customers, while the wiper insert option boosts feed rate capabilities and surface finish quality.
\nPramet\u2019s new double positive 45\u00b0 milling cutter, S45OE, is available in diameters up to 200mm and supports internal coolant delivery.
\nIts versatile design allows the same cutter body to be used with both the octagonal inserts for face milling and the round inserts for face and copy milling applications.
\nSuitable for use even on machines with limited power, the combination of new inserts and cutter offer high metal removal rates with low cutting force. The risk of chatter is also reduced \u2013 an important consideration when machining valuable components.
\nKarel Tiefenbach, indexable milling product manager at Dormer Pramet, said: \u201cOur latest package of products for stainless steel offers additional economical and versatile options for the customer. The cutters design features positive axial and radial face angles, promoting a good cutting action and directing chips away from the work-piece. Our S45OE range offers a wider selection of diameters and enhances our line of\u00a0cutters with double positive geometry. This is especially beneficial\u00a0when the work-piece is fragile, the fixture is unstable or the component material has the tendency to work harden \u2013 a common issue when machining stainless steel.\u201d
\nFor use with the OEHT inserts, three new positive geometries \u2013 MF, MM and M \u2013 have been introduced for various cutting conditions.
\nThe MF is a sharp and highly positive geometry for finishing applications in stainless steel, mild carbon steel and non-ferrous metals. MM is a sharp and positive geometry for machining stainless steel in medium cutting conditions.
\nThe M is a positive geometry with stabiliser – suitable for difficult cutting conditions in materials such as carbon steels and harder stainless steel.
\nThe new geometries offer reduced cutting forces and increased durability for machining with or without coolant.<\/p>\n","protected":false},"excerpt":{"rendered":"
