Ann Arbor SPARK worked with American Broach to
help the company secure incentives from Michigan and the City of Ypsilanti.
Designed specifically for the Swiss-type and gang-style lathes, the Genevieve Swiss 2160 rotary broach head eliminates the need to indicate the broach to
center making setups faster and easier.
Heat treating is also necessary to stress-relieve the broaches and can be performed as many as five times during the broach manufacturing process at National Broach to ensure broach tool stability.
Precision CNC grinders and wire EDM machines enable National Broach to provide customers with tools that meet or exceed industry standards.
This was the experience of the Weldon Tool Co when it installed a broach to
machine flats onto cylindrical surfaces of end mill shanks.
Simple spacers are fitted on both sides of the slotting broach to
provide holder rigidity.
