OptiMill-Uni-Wave

The OptiMill-UniWave can be used for many materials. “Above all, parts made of steel and stainless steel are machined with our milling cutter”, says Ulrich Krenzer, Managing Director of the MAPAL Centre of Competence for solid carbide tools.

The substrate used for the OptiMill-Uni-Wave is a carbide with particularly high ductility and high-temperature stability. A coating based on aluminium chromium nitride provides excellent
wear resistance and gives the tool extreme thermal shock stability.

But that is not enough. “We took a close look at the entire geometry,” Krenzer explains. Both the
unequal spacing of the cutting edges and the unequal pitch of the tool ensure significantly
improved smooth running. “During machining with the redesigned OptiMill-Uni-Wave, we significantly reduced vibrations compared to other roughing milling cutters,” says the Managing
Director.

• 30 percent better tool life in steel*
• 37 percent higher feed rate at significantly higher cutting depths (up to 2xD)*
• 15 percent lower spindle drive power due to lower cutting forces**
• 40 percent lower pull-out forces**

* compared to the OptiMill-Uni-HPC-Rough roughing milling cutter (in 42CrMoS4)
** compared with a milling cutter with straight cutting edges

When machining steel (42CrMoS4), for example, a cutting depth of 24 mm (2xD) can be removed for a tool diameter of 12 mm with a cutting speed of 160 m/min and a feed rate per tooth of 0.045 mm. A material removal rate of 864 cm3 per minute is achieved. The use of the complete cutting edge length – together with the high cutting data and machining rates -guarantees the high cost-effectiveness.

The OptiMill-Uni-Wave can also be reground. “In order to make the best possible use of the
cost-intensive carbide, we recommend that the milling cutter be reconditioned exclusively by the manufacturer,” emphasises Krenzer. To exploit the full potential of the tools, re-grinding and
re-coating to original manufacturer quality are essential. Only then is it possible to guarantee reliable, consistent machining results and machining performance of up to 100 percent compared to a new tool. The risk of a tool fracture and the related risks of damage to the part or machine are minimised.
