• Cycle time reduction as a result of 100% higher removal rates when compared with carbide milling cutters
• Tangential technology for the highest cutting edge stability
• Cutting depth up to 12 mm

In series production, face milling cutters with carbide cutting edges are predominantly used for the initial cut for roughing parts made of aluminium. Finish machining then usually takes place with adjustable, PCD-tipped face milling cutters that can be moved with very high cutting parameters due to the cutting material. The cutting speeds of the conventional roughing milling cutters on the other hand are limited and typically at around 300 m/min.

The PCD roughing milling cutter is a new tool in the MAPAL program that is manufactured with an inner coolant supply in the 63 – 200 mm diameter range. The PCD rouging milling cutter utilises the outstanding properties of PCD during aluminium machining even for the initial cut with cutting depths up to 12 mm. Compared with carbide tools, the cutting speeds of MAPAL milling cutters can be increased to 3,000 m/min and the removal rates increased by up to 100% resulting in considerable cycle time reductions.

The PCD blanks are soldered in the tangentially fitted carbide inserts. The cutting edge is particularly stable thanks to the tangential technology. The smooth cut, the large chip areas and therefore the very good chip removal and the stiff steel tool body allow for a very high removal rate.
