I have just made a cnc spm machine for collet slitting.
Presently we are facing some problem specially for it's circular saw blade.
We are using High speed steel circular saw blade to slit a collet
(material EN37) as we are not getting proper material for the same & our circular saw blade get worn after couple of pieces. We are using normal cutting oil mixed with water.
Kindly suggest me a suitable tool for the same.
