Case Study: Rambo Drill Cycle Time Reduction

SUMMARY OF RESULTS

THE CHALLENGE

A  manufacturer was machining 2 pin bores on a high volume automotive part made out of ductile iron.
Originally the manufacturer was drilling then reaming the pin bores. The Monaghan team was brought in to help reduce cycle time and the number of tools needed.

OUR SOLUTION

After consulting with the Monaghan team, we recommended an MK Tool’s Rambo Three Flute speed drill with a GTX coating. This drill eliminated the need for a second tool (reamer) and reduced cycle time by 5 seconds per part.

FINAL RESULTS

After working with the Monaghan and MK Tool’s team the manufacturer was able to reduce cycle time by 5 seconds per part and eliminate a tool from the operation.
At 225,000 estimated annual units, and 5 seconds saved per unit because of the MK Tool’s solution, the manufacturer was able to save 312 hours per year!
