Alcester-based Seco Tools (UK) Ltd (
www.secotools.com) has introduced two solid-carbide end mills that are said to boost metal removal rates and provide improved tool life.
The Jabro-HFM JHF181 is a range of cutters for the high-feed milling of hardened steels and nickel-based alloys. According to Seco, these cutters can increase metal removal rates by up to 30% in comparison with more traditional solid-carbide end mills.
JHF181 cutters are particularly effective where long tool overhangs are required and where a mix of multiple axial and radial machining operations is required.
The cutters feature Seco’s newly developed HXT coating, which is said to give good thermal protection and wear-resistance.
They are available in two-, four- or five-flute options, in diameters ranging from 2 to 16mm and lengths from 2xD to 7xD. The cutters also have through-tool coolant capability for diameters between 6 and 12mm.
Other new introductions are the Seco Jabro-Solid2 JS564 and JS565 solid-carbide end mills, which have been developed specifically for roughing operations on materials that include steels, stainless steels and titanium alloys.
These cutters provide 20% longer tool life than their predecessors, thanks to features that include stable tapered cores and polished NXT coatings.
According to Seco, JS564 and JS565 accommodate high radial engagement without the need to compromise feed rate or speed. Furthermore, positive ‘front teeth’ geometries on both cutter ranges mean the tools can be used for axial and helical interpolation operations.
Another benefit is that newly developed chip-splitter options create small chips when using long cutting lengths, aiding chip evacuation.
JS564 and JS565 are available in four- and five-flute versions with a range of cutting diameters and lengths. For both ranges, cylindrical shank diameters can be selected from 3 to 20mm, with Weldon shank diameters available from 6 to 20mm.
