Modern tool monitoring ensures reliable production
Dedicated tools for lead-free brass machining and optimized parameters allow economical production despite the elimination of lead from electrical connector alloys. However, premature wear of the tool cutting edge could have negative consequences on the quality of the produced parts.
At the high production rates of a modern transfer machine, a worn tool edge could produce thousands of defective pieces in as little as 30 minutes. Recovering them from the containers of finished parts is a long and risky undertaking; missing even one defective piece could compromise the reputation of the manufacturer. For this reason, the entire production batch should be thrown away.
To avoid this, high-tech companies have recently launched tool monitoring systems with increased sensitivity and extremely fast sampling. Tool wear can be detected immediately, initiating an immediate stop of the machine that allows the operator to replace the worn tool and remove the few pieces of non-compliant quality. These modern monitoring systems are also easy to use, thanks to automatic learning of load limits.
