Outstanding milling results with CrazyMill Cool SF and High Efficiency Milling (HEM)

The newly designed milling cutter with through-tool cooling for superfinishing sets new standards for milling in grinding quality. With High Efficiency Milling (HEM), an Ae of 0.002 – 0.02 x Ø is maintained.

The selected carbide, the geometry, the coating, and above all the through-shank coolant supply, which maintains constant temperature at the cutting edges and removes the chips efficiently from the working area, support increased cutting speeds, high axial depths of cut, ap (up to 4 x d), and elevated feed rates.

Two versions of superfinishing endmills are available in the diameter range from 1.0 to 8.0 mm (.039“ to .315“, fractional inches available): type M up to 3 x d and type N up to 4 x d.

Climb milling and conventional milling

Mikron Tool recommends climb milling for the machining of side and pocket milling. The chip thickness here is greater at the beginning and decreases continuously; the cutting forces remain low. With conventional milling, however, high cutting forces would push the milling tool away from the part. Thus, surface quality decreases.

Finishing

Mikron Tool has determined the ideal cutting parameters (ratio of tool life to process reliability) for the use of CrazyMill Cool SF. These are listed in the cutting data charts for the milling tool's diameter, milling tool type and type of machining (slot milling, side milling) as well as the material to be machined. Unique cutting data tested at Mikron Tool such as cutting speed vc, feed per tooth fz and cutting depth ap or cutting width ae ensure quick and safe machining.

The cutting data chart overview for material group, type of material, degree of hardness or tensile strength, material number, DIN and  AISI/ASTM/UNS ensure a quick determination of the cutting data to be used.

An impact-resistant and user-friendly drill packaging is absolutely necessary for CrazyMill Cool SF. Mikron Tool offers all tools of the CrazyMill Cool family in a high quality, single package.
