Practical examples

Part: Mold
Material: S45C / C45
Cutter: TRRQ12M050B22.0R05 (DCX = 50 mm, CICT = 5)
Insert: RQMT1204ENC8-MM
Grade: AH3135
Cutting conditions: Vc = 125 (m/min)
fz = 1.25 (mm/t)
ap = 0.5 (mm)
ae = 50 (mm)
Application: Profiling
Coolant: Air
Machine: Vertical M/C, BT50

The competitor’s cutter resulted in edge chipping and could not complete the machining of one workpiece.
FixRMill demonstrated no edge chipping and completed one workpiece thanks to its tough AH3135 grade inserts.

Part: Generator part
Material: SUS304 / X5CrNi18-9
Cutter: TRRQ12M050B22.0R06 (DCX = 50 mm, CICT = 6)
Insert: RQMT1204ENC8-MM
Grade: AH3135
Cutting conditions: Vc = 75 (m/min)
fz = 0.3 (mm/t)
ap = 1 (mm)
ae = 3 (mm)
Application: Profiling
Coolant: Air
Machine: Vertical M/C, HSK100

Due to a long overhang setup of 4xD and insecure anti-rotation feature, the competitor’s cutter allowed the inserts to rotate during machining, yielding damage to the insert pockets and short cutter tool life.
FixRMill prevented insert rotation thanks to its anti-rotation system, providing the cutter with security and long tool life.
