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 in April is available in its latest 2016.1 brochure. To order a printed copy or for more information contact your local Dormer Pramet sales office.

The versatile and robust VSM17 platform from WIDIA provide true 90-degree walls and excellent stepless finishes.

With cutters that can be used for shoulder milling, profiling, face milling, slotting, ramping, helical interpolation, and circular interpolation, all while achieving true 90-degree shoulders, the Victory Shoulder Mill (VSM) 17 platform from WIDIA is a robust and versatile job-shop winner.

Designed for low horsepower draw and free machining, the VSM17 delivers an effective one-two punch of reduced horsepower at the machine and higher speed and feed rates that mean more parts per shift. “For a wide range of work materials, the entire VSM 17 platform is optimized to provide higher productivity for job shops” says Adarsh Sowcar, global product manager, indexable milling.

VSM17 cutter bodies have an integral chip gash design for excellent chip evacuation along with hardened-steel construction and hardened pocket seats which provide high resistance to deformation. VSM17 offers aggressive ramping capability up to 8.8° and a maximum 0.642” (16.45mm) depth of cut. VSM17 is available in shell mills, screw on cutters, cylindrical shank and Weldon shank end mills with internal air and coolant capability.

VSM17 inserts have strong cutting edges, multiple corner radii, and positive rake faces that provide a true 90-degree wall while providing excellent wall and floor surface finish.

VSM17 starter kits are available now through local authorized WIDIA distributors. These kits feature a cutter body and ten inserts.

Featured in NOVO
Moreover, the VSM17 platform is available through NOVO, WIDIA’s digital process knowledge application. With powerful process knowledge available on iPad and other digital devices, NOVO helps users define machining features, such as ramping or slotting in specific work materials, and then immediately reduces the product set to those like VSM17 that can do the job. This provides far more useful process knowledge than any online catalog alone, all obtained in a fraction of the time.
