2.5d CNC machining an aluminum torque arm
Channel: Christian Knüll
Date: 2017-06-04

Just broke the torque arm for my bicycle hub and needed a quick replacement.

Material is 20mm Al Mg 4.5 Mn.
Trochoidal machining with 6mm single flute and 1/8" 2 flute tools.

Surface finish is a bit rough because the 1/8" tool is quite worn out and I didn't care enough to add a finishing pass - I just want to ride my bike again :-)
