An advantage of having a keyway is allowing a higher transmission of torque between a moving part and the shaft that it is mounted on. Another criterion of classification is construction of the machine where we have vertical, horizontal and rotary broaching machine. Another thing to keep in mind is that it will be less expensive to do this Traditional Keyway Broaching in Press with a standard square broach with an across-flat dimension equal to the width of the keyway, rather than a specially formed keyway broach. Anyone who is a non-believer either doesn't know how to properly set-up/program their machine or simply hasn't tried one. Because we make these broaches daily, we offer very fast delivery of custom broaching tools.
Apex has the capability to sharpen most any style broach cutting tool, without expert sharpening your broaching tool will not perform properly. As the prepared workpiece is turning, the rotary broaching tool/toolholder advances toward it. Because of the 1-degree axial tilt, only one corner of the tool engages the workpiece at first. At the present time, a form of machine called a draw-broaching machine is Traditional Keyway Broaching in Press used in many shops, and the tools are drawn through the work. At the same time, these are also really useful for manufacturing engineers to make a product / a process more sustainable.
The strength of the broaching machine is generally rated in tons, and, in concert with the broach and hub material being cut, will determine how much material can be removed with each cutting pass. The technology was developed decades ago, but rotary broaching companies continue to improve tool holders and tools to increase tool life and make the technique easier to use.
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.
