CH3515 – Tough productivity boost
06:14

We were contacted by one international customer about improving productivity in a machine cell which was a bottle neck in their production. After analysis of the said cell, one of the improvement possibilities was this facing operation with heavy interruptions. It was identified as an H35 operation and the new CH3515 was the obvious choice. The goal was to achieve 100 parts tool life to have the same change cycle as other tools. It was easily achieved and the success was total. Cycle time was reduced with 40 s per part, which results in 11 000 hours of saved machining time. Annually!
