Flat knurling

[kendo]

What would be the most common way of imparting a diamond knurl to a flat piece of material?

The piece is 1/8" thick and the knurl is 9/16 wide by 1" long and .01" deep.

Thanks,
Kenny

I cant remember the name of it but I use it to engrave. Its a .125" dia carbide blank ground to a point with 1/2 the diameter ground away. essentialy a single flute. Msc carries them. you could simply machine the criss cross pattern to get the effect. I can tell you exactly what its called on monday

thanks, I always just called 'em engraving bits

when I told the engineer thats the only way I'm sure it would work, they balked at what they thought would be too high a cycle time

yah. add "x" to the run time. Instead spend "xx" trying to figure out a better way. Thats management for ya. I guess you could stamp it in a second op with a special tool

What about taking a tap that has the correct pitch to match the knurl you want, and grind all the flutes down but one. You would have to make two set-ups, one 45* left, one 45* right, but all your lines would be done at one time.
