Mapal Milling from solid: high performance in aluminium and steel

Editor: Steffen Donath

High infeed depths as well as the highest feeds during roughing are possible with the new Optimill-SPM-Rough, according to Mapal.

The reason for this performance is its knurled roughing geometry that ensures the power consumption during machining is significantly lower compared to tools with a straight cutting edge. Furthermore, the heat introduction into the part is minimal due to the excellent plunging characteristics of the tool.

For finishing contours and pocket walls — even at large depths in one pass — Mapal is announcing the Optimill-SPM-Finish with newly developed geometry. It operates without problems even with large wrapping — also in the corners with enormous tool contact and a high load, the tool remains stable. The optimally designed cutting edge geometry ensures there is no vibration during the machining. The chip flutes are polished; as a consequence chip removal functions optimally.

The Optimill-Uni-Wave is the tool of choice if the issue is full slot milling with a groove depth up to 2xD in different materials, the company states. Due to its geometry, the highest machining rates are possible. Irrespective of all the advantages of the Optimill-Uni-Wave, machinists often faced the difficulty that chip removal was not reliable, particularly in steel materials during the machining of slots with a depth ≥ 1.5xD, Mapal explains.

For this reason, Mapal now offers the Optimill-Uni-Wave also with central internal cooling. This feature ensures optimal removal of the chips and longer tool lives. In addition, Mapal is announcing the Optimill-Uni-Wave as an extra long version.
