(Gary Ezor, President & G.M. w/ Walters CNC 4-Axis Creep-Feed Broach Grinder)
At Pioneer Broach we have solved the problem of inconsistent tooth forms by employing state-of-the-art Computer Numerically Controlled creep-feed grinding machines. Near perfect (.00008) tolerances are held utilizing CBN(Cubic Boron Nitride) plated metal wheel forms, along with high pressure heavy coolants. This process produces consistent tooth gullet forms without the heat and friction generated by conventional grinding. Broaches manufactured at Pioneer Broach in this manner are specified as "CNC Qualified". The benefits of these broaches include superior workpiece surface finish, accuracy and longer tool life. In keeping with our philosophy of finding a "better way" to manufacture, we have developed unique application software enabling us to grind complex broach forms on our "CNC" grinders. These forms include Involute Spline, Fir Tree, Dovetail Root, Cam, Rifling and many others. Our "CNC" Broach Grinding Department consists of (4) 4-axis broach grinders and our most recent addition - a Walter 6-axis Heli-Center BG grinding machine. Pioneer Broach Co. currently operates among the largest "CNC" broach grinding departments in the U.S.A. (Mike Ochs, Chief Mfg. Engineer w/ One of the Worlds Largest CNC Broach Grinder, Walters "BG" 6-Axis.)   Broach Types: Surface Broaches:
• flat • serrated • concave • cam-shaped • convex
Internal Broaches: • straight/involute spline • serration • rotor cut style • round • D-shape • double "D" shape • keyway • body keyway • oval • square • rectangle • Bearing Pocket • hexagon • octagon • bore • rifling • pot (external)

Special Broaches:
The engineering and design department here at Pioneer Broach has the ability to help you design any broaching tool within the realm of feasibility.
