1 October /10 Improved, New Grades and Chip Breakers for Machining Heat Resistant uper Alloys

2 2/10 KEY POINT TaeguTec s new grades and chip breakers for heat resistant super alloys (HRA). TT3010 and TT3020 grades. With a glossy yellow sheen, the TT3010 grade is characterized by high abrasion resistance and high bonding strength due to the use of an ultra-fine substrate. The combination of this abrasion resistant, high bonding strength ultra-fine substrate and a special coated layer enables great chipping resistance which prevents built-up-edges. The new grade is suited for low depths-of-cut finishing plications. The TT3020 grade, with a glossy yellow sheen, uses an ultra-fine substrate that generates high abrasion resistance and toughness during machining. A smooth coated layer surface made through a special treatment process enables excellent resistance to built-up-edges. For HRA materials, it is TaeguTec s most recommended grade for the machining of scaled surfaces and light external plications in the low to medium speed range. MG and FG type chip breakers. The MG chip breaker is a negative press type insert with a sharp cutting edge that reduces cutting resistance and heat generation during machining. Additionally, the insert s high rake angle generates smooth chip evacuation while the insert s wide top face means better insert seating, which promotes stability during operations. The FG chip breaker is a positive ground type insert. Its sharp cutting edge generates low cutting resistance while guaranteeing high precision machining. The chip breaker minimizes heat when machining heat resistant super alloys and the small dot located in the corner is effective for chip control. Furthermore, it is possible to finish machining without workpiece deformation even when processing thin workpieces.
