Q:Why don't carbon tools steel be used to make Broaches and gear cutters?

Carbon tool steel is cheap and easy to forge, and its machinability is better. The main disadvantage of carbon tool steel is its poor hardenability. It needs water, brine or alkaline water quenching. The tendency of distortion and cracking is great, and its abrasion resistance and thermal strength are very low. Therefore, carbon tool steel can only be used to make some small hand tools or woodworking tools, and the accuracy requirements of the small cold is not high, simple shape, small size, light load of mold, such as used in the manufacture of small punch, scissors, die, cold die etc..Broaches and gear cutters are usually made of high speed steel

Q:I am currently in a lathe machinery factory, factory of broaching machine really curious.It is a hole with the kind of cylindrical broach broaching machine, after a day's work is down to a special knife Seurat with special machine tool grinding.Would you please tell me that the diameter of the broach is not smaller since he repaired it? Wouldn't it be possible to process the required size?

Repair is the front edge of the broach, the blade has a wide blade. After grinding, only the edges become narrower and have nothing to do with the outer circle. Unless the grinding too much, will affect the outer diameter of the cutter tooth. However, the last 4-5 teeth of the broach are the correcting teeth for correcting the outer circle, so the sharpening broach has no influence on the final processing size.
