Hi
I have a job that I need to make some custom pattern knurling wheels.
They are for form knurling some 8mm 420 stainless rods up to 130mm along the length. I have tried a few methods so far without good results.
I am going to make a large heavy duty scissor type knurler to hold the knurling wheels. The wheels will be ~80mm diameter and 130mm wide (full width). The style of the knurled pattern means that I am unable to make a small wheel and traverse. It has to knurl the full width at once. This means I need a relatively heavy duty tool. The wheels will be supported at both ends by arms made from 100m x 20mm steel bars.
My question is regarding the knurling wheels themselves. I am planning on using D2 as it has been recommended for this, but I am unsure about what hardness to aim for. I have a pretty accurate kiln but I haven't found any info on what hardness to give the best strength/toughness combination.
Any suggestions appreciated
Thanks
