Dense carbides mill cast iron at 45,000
rev/min
Specifically designed for mould and die toolmakers and high speed machining applications, the use of extra dense, sub-micron grade carbides in end mills enable cast iron milling at 45,000 rev/min.
The fast-growing cutting tool specialist TaeguTec UK has introduced a new line of end mills specifically designed for mould and die toolmakers for use in high speed machining applications The new company, part of IMC Group, has created its Art Mill range, which will be launched at MACH 2002

Catalogue inlcudes latest solid carbide end mills
An extensive range of solid carbide end mill tooling is included among a wide variety of new tooling products described in the manufacturer's latest catalogue.
Carbide roughing end mills have 45deg wave helix
Ideal for cutting steel, cast iron, stainless steel, exotic alloys, graphite and materials with a hardness up to 470HB, a range of 45 degree wave helix roughing end mills come in three lengths.
Art Mill combines excellent wear-resistance with the ability to run at speeds of up to 45,000 rpm, using the latest technology developed by TaeguTec.
With around 95% of mould and die tool costs coming in the production process, TaeguTec's philosophy is to focus on helping manufacturers achieve lower production costs, rather than just reducing tool costs, which account for 5% of costs and where potential savings are smaller and much harder to achieve.
Milling cast iron, Art Mill's properties allow it to run at speeds of 45,000 rpm for a 3mm diameter end mill and 12,075 rpm for a 12mm diameter end mill - both with feeds of 2800mm/min.
The Art Mill end mills also have a corner radius version that allows toolmakers to do away with the extra finishing process - required at the end of a cut to generate the corner radius - needed to strengthen the mould and lessen stress points.
When milling at such speeds, dynamic balance is vital and Art Mill is symmetrically designed to ensure balanced operation and ultra-precise run-out.
If the tool is set up correctly, Art Mill will guarantee precision of +/- 5 microns.
The speeds that can be achieved and Art Mill's ability to machine up to Rockwell 55 steel are down to two key factors in its design - the submicron grade carbide and the physical vapour deposit (PVD) coating TaeguTec uses.
Art Mill's submicron grade carbide packs more grains of carbide much closer together than standard carbide and is pressed to produce a super-tough material.
This is then coated with the PVD (TiAl)N coating to give the extra wear resistance.
TageuTec UK's General Manager Ronnie O'Byrne said: "Our belief is to invest in developing new products that are designed to harness the capabilities of the new machine tool technology available and work with this as it was intended.
"Art Mill will make it easier for those with HSM equipment to run more effectively at the high speeds and achieve the time savings that are so sought after.".
