The Challenge

The customer manufactures battery packs made from hard plastic for the aerospace industry. They are using a Haas VMC CAT40 taper VF3 running without coolant.

The customer needed a more cost effective solution. They asked Allied Machine to decrease the cycle time and reduce the overall cost of production.

The Original T-A reduced the cycle time and provided substantial reduction in cost.
