DrillForceMeister – Axel pin for wind mill – AH9130
IMPROVED TOOL LIFE
In deep hole drilling with L/D=8, competitor's products resulted in unstable machining, leading to tool failure after a single hole.
By applying the SMC head with high centering performance, stable machining was achieved and tool life was extended.
