When the grade gets tough
Pramet has launched a new milling grade and also expanded its face milling range for stainless steels.
The M6330 grade has been developed specifically to achieve longer cutting edge durability and reliability in a range of difficult-to-machine materials with and without coolant.
Particularly suited to adverse cutting conditions, including interrupted cutting, the grade is now available with many of Pramet’s most popular inserts, including the ADMX, HNGX, LNGX, LNMU, OEHT and numerous other ranges.
It promotes greater operational reliability and tool life, with a high resistance to heat-related cracks. This is due to improved abrasion resistance from a new substrate and PVD coating.
The new grade is the latest of many new products recently launched by Pramet for machining stainless steels.
Meanwhile, Pramet has also added to its face milling range for stainless steel with new, larger diameter cutters and inserts for greater depths of cut and more powerful machines.
These latest tools include the octagonal OEHT 09 inserts, suitable for unstable conditions and machining fragile components in stainless steels and soft steels up to depths of 5mm.
The versatile tool can be used for both roughing and finishing operations, providing increased tooling economy and significant savings on machine time.
In a recent product test, machining a piece of steel (3900mm x 3200mm) with coolant, the OEHT performed the roughing and finishing operation in 52 minutes. A competitor tool performed the same task in the same conditions in 252 minutes with roughing and finishing operations done separately.
A new range of round inserts, REHT 24, for face and copy milling and the XEHT 09 wiper inserts add to the options available. All can be clamped into the same milling cutter, further increasing versatility and cost efficiency.
A wide assortment of new milling cutters, ranging from 80 - 315mm diameter, is also available. Internal coolant delivery is supported by each cutter, including for large diameters.
An overview of all the new products launched by Dormer Pramet is available in its latest 2016.1 brochure. To order a printed copy or for more information contact your local Dormer Pramet sales office.
