Accurate and efficient milling with CrazyMill Cool Z4

The newly designed, through-shaft cooled pre-machining and finishing milling cutter sets new standards in the milling of sides and pockets in terms of cutting speeds, performance, tool life and surface quality. It combines HSC (HighSpeedCutting) and HPC (HighPerformanceCutting), thus becoming an HSPC (HighSpeedPerformanceCutting) milling tool.

The selected tungsten carbide, the geometry, the coating and especially the through-shaft coolant supply, which ensures perfect cooling of the cutting edges and removes the chips cleanly from the machining area, support high cutting speeds, high depth feed ap (up to 4 x d) and high feed rates. 

Four versions of cylindrical (small protection phase of 45°) and toric (corner radius) micromills are available in the diameter range from 1.0 up to 8.0 mm (.039“ up to .315“, fractional inches available). Type A for maximum milling depth up to 2 x d (cutting length 2 x d), Type C up to 5 x d (cutting length 2 x d), Type M up to 3 x d (cutting length 3 x d) and Type N up to 4 x d (cutting length 4 x d).

Climb milling and conventional milling

Mikron Tool recommends climb milling for the machining of sides and pockets. The chip thickness 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.

Maximum ramp angles in linear ramping or helical interpolation

Note: In case of linear ramping or helical interpolation refer to cutting data for pre-machining with a reduction by 35% of fz.

Pre-machining

Finishing

Mikron Tool has determined the ideal cutting parameters (ratio of tool life to process reliability) for the use of CrazyMill Cool Z4. 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 Z4. Mikron Tool offers all tools of the CrazyMill Cool family in a high quality, single package.
