The History of American Broach & Machine
Founded by Francis J. “Frank” Lapointe, American Broach & Machine began its journey in Ann Arbor, Michigan. The company capitalized on the burgeoning automotive industry, providing innovative broaching solutions. Over the decades, American Broach expanded, particularly during World War II, where it became a significant supplier of broaching tools to munitions factories.
In 1961, the company was acquired by Sundstrand Machine Tool Co. and later consolidated into their operations. The legacy continued until April 2023, when American Broach closed its doors but still holds a prominent place in the industry’s history.
Types of Broaching Processes
Broaching is a machining process that utilizes a toothed tool to remove material from a workpiece. There are several types of broaching processes, including:
Linear Broaching
This process involves a straight-line motion of the broach across the workpiece. It is commonly used for producing flat surfaces and keyways.
Rotary Broaching
In this method, the broach is rotated while being fed into the workpiece. It’s ideal for creating internal shapes like hexagons or squares.
Pull Broaching
The broach is pulled through the workpiece, making it suitable for larger parts. This method is efficient for high-volume production.
Push Broaching
The opposite of pull broaching, this method involves pushing the broach into the workpiece. It’s often used for smaller components.
