Mikron Adds Toric Version to Milling Cutter Family

Mikron Tool has expanded its CrazyMill Cool P&S milling cutter family, which was developed for roughing and finishing oprations, with a toric version. The drill/milling cutters are designed for machining stainless steel, titanium, CoCr alloys and superalloys. They can plunge perpendicularly into the material up to 1×D and then continue machining laterally, according to Mikron.

The cutters are available in the diameter range of 0.039" to 0.315" (1 to 8 mm) in two versions: Typ A 2.5×D CrazyMill Cool P&S Corner Radius, with a cutting length of 2.5×D, Z3, and Typ C 5×D CrazyMill Cool P&S Corner Radius, with a cutting length 2.0×D, Z3.

The tool is suitable for milling of holes, ramps, pockets, grooves and sides and designed for difficult-to-machine materials. Its geometry is said to enables process-safe, low-vibration plunging. The wide chip space in the head section allows chips to be collected during the drilling process and evacuated laterally into extended flutes.

It features adjusted rake and clearance angles, stable cutting corners and cooling channels integrated in the shank that are designed to deliver constant, targeted cooling in every position. The cooled cutting edges are meant to allow high speed and feed rates. 

The cutter is made of ultra-fine grain carbide, which is characterized by high toughness and is said to support stable, vibration-free milling. It has an SNP coating that increases surface hardness and enhances wear and heat resistance, according to the company.

Mikron says these features enable high chip removal rates, thanks to the high cutting and feed rates and an infeed of 1×D  each.
