Now available in the UK from Floyd Automatic Tooling is the new CrazyMill Cool Micro series of micro end mills manufacturing by Mikron Tool. With micro-machining applications increasingly commonplace in the electronics, medical, optics, automotive, aerospace and defence sectors, Floyd Automatic says the high-performance CrazyMill Cool Micro end mills are a game-changer.

For the first time, engineers at Mikron Tool have successfully transferred high-performance cutting tool geometries to micro-dimension end mills. Suitable for operations as diverse as sidemilling, helical interpolation, slot milling and drilling, the CrazyMill Cool Micro is available with three or four flutes, diameters from 0.2 to 1mm, and effective cutting lengths of 3xD and 5xD. The high-quality micro-grain carbide grade permits the grinding of special filigree geometries that maximise strength and performance, minimising the potential for tool breakages, especially when machining challenging materials.

The combination of innovative geometries, the high-quality carbide grade and a patented new cooling concept deliver double the tool life performance and three times higher productivity levels than rival product lines, reports Floyd Automatic. Integrated through-coolant channels guarantee high levels of cooling. Furthermore, with a cooling channel for each of the three or four flutes, swarf evacuation issues in micro-machining applications are now a thing of the past.

Also introduced is coating technology that prevents the loss of sharp edges which can be so critical in micro-machining applications. The new arrivals are available with an S geometry for machining stainless steel, steel, cast iron, non-ferrous metals and titanium alloys, while the SX geometry type is suited for particularly challenging materials such as Inconel, Monel, and CoCr alloys.
