Kennametal introduces new grade of indexable milling insert
November 8, 2011
Kennametal has introduced a new grade of indexable milling insert, specially engineered for high-speed dry machining in light to medium milling of steel and stainless steel parts under stable conditions.
New KCPM20TM insert grades from
Kennametal are available for face,
shoulder, and profile milling applications
The ‘BeyondTM KCPM20’ grade is being recommended as an ideal optimisation grade for stainless steel machining applications where coolant is not used and excellent wear resistance is required, states the company.
The new inserts are CVD (chemical vapor deposition) coated, but whereas conventional CVD coatings are under tensile stress, these inserts undergo a proprietary post-coat treatment on all surfaces to reduce this stress, which improves coating adhesion and reduces micro-chipping.
More uniform and reliable wear of the cutting edge results in improved and more consistent tool life. Smoother surfaces also lower frictional forces, another factor that expands applications and permits higher cutting speeds. Additionally, the inserts are top- and bottom-ground after coating for a better seating surface in the toolholder, which improves security.
