High Efficiency Milling with CrazyMill Cool CF

The newly designed milling cutter with through-tool cooling for pre-processing (roughing + semi-finishing) and finishing sets new standards when it comes to chatter-free milling. Specially developed for High Efficiency Milling (HEM), this high-performance milling cutter guarantees outstanding surface quality (Ra 0.5 µm or better).

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 endmills are available in the diameter range from 1.0 up to 8.0 mm (.039“ to .315“, fractional inches available): type M for cutting length 3 x d and type N for cutting length 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.

Mikron Tool has determined the ideal cutting parameters (ratio of tool life to process reliability) for the use of CrazyMill Cool CF. 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 CF. Mikron Tool offers all tools of the CrazyMill Cool family in a high quality, single package.
