Boehlerit developed an entirely new high-end milling programme


The new milling range of Boehlerit comprises 10 innovative tool systems and 11 new milling grades. All modern materials can be reliably and economically machined with the new tools that are fine-tuned to the requirements of face and step milling.


The quality standards in milling have been defined by the Boehlerit cutting experts for decades now – and the latest proof of their expertise was presented at EMO 2015 in Milan. The development engineers in the Austrian steel industry town of Kapfenberg put all their technical know-how into a dynamic FEM design (finite-element method) for Boehlerit milling equipment to create stable milling tools with excellent fatigue strength properties, optimum chip formation and precise concentricity characteristics. All tools are nickel-implanted and owe their long tool life to special materials and heat treatments.


The basis of the new high-end milling range are 10 innovative tool systems, including multi-purpose tool systems where one base body makes two types of machining possible. This reduces the carrier body costs and saves warehousing expenses. The range includes highly economical high-feed tools and face-milling cutters with 16 edges. A total of 11 new milling grades cover all the many milling tasks of face or step milling in all current materials. They combine machining reliability and economic efficiency.


Various carbide substrates are used to produce the range of milling grades, or indexable milling inserts, fine-tuned to cover an extensive range of face and step milling operations: from roughing to finishing, from cast to steel, stainless materials and aluminium. The milling grades guarantee minimal wear on free areas and a higher resistance to chipping of the cutting edges. Resistance to thermal cracking or crater wear is also ensured. A special point to note here: Boehlerit uses exclusively no-conflict (fair) resources for the production of its carbides.


The patented, innovative TERAspeed 2.0 AlTiN layer, deposited by means of HR-CVD technology (HR = High Reactivity) is a special highlight of the new milling programme.  The high aluminium content of this AlTiN layer and its innovative nanostructure make it possible, for the first time, to combine properties that are conflicting by definition – such as remarkable toughness, outstanding layer hardness and wear resistance. The modern layer is available in the milling grades BCP20M (HC ISO P20), BCP30M (HC ISO P30) and BCK15M (HC ISO K15).


Another innovative carbide layer, specially designed for milling, is the thick PVD AlTiN Goldlox layer. Its high wear resistance at high temperatures improves tool life for steel materials. And its particularly smooth yellow Goldlox top coat makes wear recognition easier. It is available in the steel milling grades BCP25M (HC ISO P25 / M25), BCP35M (HC ISO P35 / M35) and the tough BCP40M (HC ISO P40 / M40) grade for steel.


The wear-resistant milling grade BCM35M (HC ISO M45 / S35) is extremely tough and has been tailored to stainless steel and super alloys; the tough BCM40M (HC ISO P40) milling grade is ideal for stainless steels.
