[PSUBS-MAILIST] Cutting circlip grooves

[hank pronk via Personal_Submersibles]

Alan,If you have a parting tool, you can grind it to the thickness that you need, but wow that is thin. You will need to buy a grinding stone and a bench grinder for sharpening, if you haven't already.  You need a special stone for the harness of the cutters.   Your grinding disk idea is not bad, just take the disk and run a bolt and nut through the centre of the disk to hold it.  Then clamp the bolt in your tool holder, spin the lathe as fast as it will go and slowly push the disk into the shaft.  This is certainly not a standard idea, but us rookie machinists have creative licence to do  this.  :-)Hank

 Hi, I need to cut a few external circlip grooves in stainless 316 rod.One is 1.1mm wide (3/64") & the other .7mm (1/32") wide. The shaft is 10mm & 8mm diameter.I have a lathe tool that fits tungsten inserts & am wondering that IF I can get an insertthe right width, whether the tungsten would be too brittle for that.Another option may be a dremmel drill & disk if I can set it up on the lathe carriage & if they havegrinding disks that diameter.Any suggestions, comments appreciated.Thanks, Alan
