CrazyMill plunges into productivity gains

Mikron Tool has expanded its CrazyMill Cool P&S plunge-milling cutter programme with the inclusion of new dimensions to achieve even deeper machining cycles.

Now available in the UK from Floyd Automatic, the latest CrazyMill Cool P&S is characterised by the ability to plunge (drill) vertically into the material, mill slots or pockets into solid material in small spaces, and conclude milling operations with finishing cycles.
Although the milling depth in the short version (2.5xD) was based on the machining of keyways, the extended range has been developed to mill the deepest possible slots and pockets with a single tool, reaching more distant machining areas of a workpiece with one cutter. The new version of the solid-carbide plunge mill is based on the same technology as the short version, transferred directly to the new line. Now, it is possible to plunge perpendicularly into the material and reach the maximum milling depth of 5xD.
Good chip removal plays an important role at this depth. There is a higher risk that chips remain in the milling zone, are broken-up and subsequently damage both the milling cutter and the milled surface. The special cutting-edge geometry of CrazyMill Cool P&S and its extended chip area provide a remedy, ensuring lateral chip removal during plunging and tool stability during deep milling.
Alberto Gotti, head of the technology and customer project centre at Mikron Tool, says: “Customers can work with this tool at high speeds and feeds, and an axial infeed of 0.5xD, achieving extremely high chip-removal rates. For the user, this means up to five times shorter machining processes and significantly longer tool life compared with other milling cutters on the market.”
The CrazyMill Cool P&S is available in diameters from 1 to 8 mm, and for a maximum milling depth of up to 5xD.
