The customer supplies gears and gear assemblies. They are manufacturing transmission gear carriers for the Hummer H3. The holes are drilled into a composite consisting of two powder metal steel components joined by sinter-brazing. The customer is expecting to produce 50,000 carrier assemblies.
Allied Machine suggested the T-A GEN2 drilling system. The tool needed to at least match the 16 IPM (406.400 mm/min) achieved by the original tool.
The T-A GEN2 met the customer’s requirements and provided significant cost savings.
