Saint-Gobain Abrasives has introduced the Norton Winter Paradigm® Plus Diamond Grinding Wheels featuring a new premium grain technology complementing the established proprietary, patented brittle-metal bond, resulting in a significant upgrade in performance on carbide round tools for fluting and gashing applications, and periphery grinding on carbide and cermet inserts grinding.

Sandvik Coromant launches GC4325; a new-generation coated cemented-carbide grade for steel turning at EMO 2013 held at Hannover, Germany. This latest innovation in tool material provides a new, higher potential for increasing cutting speeds and a longer, more predictable tool life with very high reliability, over an extended broad ISO P25 application area.

With all this in mind an average productivity increase of 30 percent from today's existing levels is now available. The grade represents a new generation of performance with coated cemented-carbide indexable inserts, providing a new potential to be tapped throughout a large and diversified application area.

Predictability has become increasingly important in today's machining, especially where there is limited supervision in production. There are always a number of threats to the edge line remaining intact long enough in steel turning. One challenge is the breadth of the ISO P25 application area, which includes several very different materials, from ductile low-carbon steels to high-alloy hard steels, bar material to forgings, castings to pre-machined parts. The advances with the new grade, GC4325, will actually help users resist holding back on cutting-data levels. The grade provides extremely high process security through its ability to retain an intact edge line.

As a bonus, the grade is highly capable of maintaining the insert edge line at higher temperatures, which translates into the capability for higher cutting speeds with added security through more predictable, longer tool life.

The wheels are the next generation of the Paradigm wheels. New grain technology, together with a new advanced lightweight core, produces lower specific cutting energy with a 25 to 50 per cent higher material removal rate (MRR), and provides significantly improved wheel life when compared with current Paradigm wheels, according to the company.

The new resin-based core, available for round tool grinding, is over 75 per cent lighter and eliminates the risk of sparks while reducing chipping, breakage and chatter, for better finishing in round tool applications. The Paradigm bond, which combines the wear resistance of a metal bonded wheel with the ease of profiling in a vitrified bonded wheel, has up to 46 per cent porosity enabling improved coolant flow for cooler cutting and reduced part burning, allowing for truing and dressing.

The insert substrate and coating of GC4325 have been developed to better withstand high temperatures, thereby reducing the effect that causes excessive wear.
