21 April 2016
Ceratizit has expanded its product range to include a MaxiMill 491 shoulder milling system with eight cutting edges and a 90° approach angle, company announced.

Eight cutting edges and easy handling

With MaxiMill 491 the top-class brand Cutting Solutions by Ceratizit is extending its product range to include a 90° shoulder milling system with eight cutting edges, technologically exploring new avenues. "Many shoulder milling systems in the market feature an extremely complex design. We have rethought the shoulder milling process and made it easy," explains Dr. Uwe Schleinkofer, head of the development department at Cutting Solutions by Ceratizit. This solution is one of the leading products on the market when regarding both production and process. The technical details are hidden in a way that the customer does not notice them directly but nevertheless benefits from the extremely easy handling. "It is incredibly easy to use the tool," says Dr. Schleinkofer. The new insert seat design enables the insert to be changed quickly, even inside the machine.

Economical thanks to eight usable cutting edges

The eight cutting edges in the carbide grades BLACKSTARTM and SILVERSTARTM are a major reason why the MaxiMill 491 shoulder milling system is exceptionally economical. "Compared to competitors the MaxiMill 491 system has a very attractive price per cutting edge," explains Mario Wolf, product manager milling at Cutting Solutions by Ceratizit. In addition, tool changing times have been reduced because the MaxiMill 491 is suitable for both roughing and finishing. Additional machining operations are no longer necessary as the approach angle is exactly 90° and the surfaces produced are very good.

High performance with excellent quality

"I don't know any other shoulder milling system with radial setting and eight usable cutting edges which is able to produce an approach angle of exactly 90°. The combination of all features makes the MaxiMill 491 unique," says Wolf. Thanks to the latest manufacturing technology the inserts produced with tolerance H guarantee outstanding axial and radial run-out, long tool life and high-quality surfaces. The tools with irregular pitch and perfectly adapted approach angles ensure reduced vibration and a smooth cut combined with low power consumption.

Start programme for a variety of applications

The milling system is suitable for universal application (e.g. face milling, shoulder milling, peripheral milling, slot milling and trochoidal slot milling). The MaxiMill 491 start programme includes tools with a nominal diameter from 32-160 mm and precision inserts in assembly size 12 mm and a corner radius of 0.8 mm. Cutting Solutions by Ceratizit offers metric dimensions for the tool holders for shell milling cutters, end mills and milling cutters with threaded shank. From June 2016 these will also be available in inch dimensions. The shell milling cutters are available with a wide or narrow pitch. The F-R-M chip grooves combined with the latest grade technologies cover applications of steel, cast iron, stainless steel and aluminium materials in the ISO ranges P-K-M-N.
