broach manufacturer


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 tools 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 broaches, 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, Broach Rifling and many others. Our "CNC" Broach Grinding Department consists of (10) 4-axis broach grinders and (4) 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.

What is CNC Qualified Machining?

CNC (Computer Numeric Control) machining is a manufacturing process in which computer software is programmed to dictate the movement of factory tools and machinery. Being CNC qualified means the broaching process is completed on CNC lathes and CNC mills instead of transferring parts to a separate key seater or broaching machine or vending your parts out. CNC Broaching enables you to make your part completely in one operation and location. This eliminates human error and produces perfectly precise results.
