TetraForceCut – Brake cover – FC250

IMPROVED PRODUCTIVITY AND TOOL LIFE

A three-corner insert was previously used for machining brake covers on construction machinery. We proposed the TetraForce-Cut instead.
The workpiece material is FC250, and to improve tool life, the wear-resistant AH8005 grade was applied.
The latest AH8005 grade enhanced tool life by 1.5 times, and switching from the conventional three-corner insert to the four-corner TetraForce-Cut significantly improved tool life per insert.
Additionally, cutting speed was increased, contributing to higher machining efficiency.
