How Rotary Broaching Works By Polygon Solutions

The Gear Works has greatly improved its internal spline and keyway broaching service with the recent installation of a 75 HP, 50 ton, horizontal broaching machine with a 72 stroke Broaching is a machining process that finishes a simple or complex bore by pulling a multi-tooth tool called a broach through the part. While keyseating does take longer than traditional broaching, it provides great flexibility in that a unique size single tooth cutters can not only be procured quickly, but they can also be quickly cut or modified at an onsite tool room to meet a unique keyway demand. While searching the internet we found a broaching tool at We were very skeptical but had nothing to lose and decided to give them a shot.
Broaching Technologies currently sell elmass Broaching machines exclusively, as we believe they are by far the best in the P10-200 NC , P20-250 NC , P36-500-NC and the P80-700-NC vertical broaching machines are sold in a two axis or three axis configuration. Broaching tools are designed according to the specifications as different types of broaches are used to remove metal from different angles.
Thus, when rotary broaching on a lathe or screw machine, when the stationary broach tool meets the rotating part, it begins spinning at the same rate as the part. Two additional limit switches at the upper and lower reversal point of the machine can be provided for security reasons. Two changes can be made from a standard rotary broaching set-up to make many broaching jobs work in stainless steel. Typical work pieces also include small to medium sized forgings, castings, screw machine parts and also stampings.
Commercially available oil hardening gauge plate seems - Hassay-Savage - ideal as the exact thickness can be easily obtained but once again during the hardening process heating caused bending problems however these were able to be 'adjusted' after tempering but I found it difficult to ensure the teeth cutting edges remained hard. Common sense will tell you, If you understand the process with - Traditional Keyway Broaching in Press - this tool, the force on the spindle generated by this tool, if programmed correctly, is no more, maybe even less than the force of a tool change. Component tray A component tray is provided for keeping the components before and after broaching on 3T machines.
Except when broaching cast iron, tungsten carbide is rarely used as a tooth material because the cutting edge will crack on the first pass. Experiment has been carried out using a vertical broaching machine for the mild steel material of different depths. Federal Broach has in-house production broaching machines that allow us to take your part design from concept to reality. Figure 11: Comparison of measured and simulated force values during broaching operation on mild steel work. Figure 2 shows the profile of one tooth and Figure 3 shows the AutoCAD drawing of the complete broaching tool. Finally, a guide post or fixture can be set-up to keep the broach aligned while broaching.
