The Deburring News
A metal stamping & cutting company in Pennsylvania had an aerospace application that needed deburring. The material is nasty Hastelloy C22 and the part is being run on a Hitachi Seiki HT20SII lathe. After boring a 1.25″ pocket a .314 hole was drilled, this drilling operation left a very stubborn burr on the back side of the part. This burr needed to be eliminated. In addition, they needed a deburring tool that gave them the flexibility to just break the edge .005 to .010 max.
After finding E-Z Burr online, it was recommended that the customer use our carbide series with “Rear / Tough” deburring (Tool #CRB0314-RT, meaning Carbide .314 diameter, Rear deburring, for Tough material). The RT geometry was aggressive enough to handle Hastelloy C22, yet due to the insert height adjustment feature, the customer was able to control the size of the chamfer to hold the desired result of .005 / .010 max. edge break.
Typically, that insert geometry will result in a chamfer 3 times (.015 /.030) the size mentioned above, but our patented adjustment feature allowed the insert to be adjusted down into the pocket for a minimal size edge break.
Out of 2,300 parts not one was rejected in QA for the burr removal after the finish boring operation. “Kid you not. That’s 2,300 parts on 1 insert.”
“Best investment in tooling we have made in a long time. We will be purchasing again and recommending every chance I get. Thank you so very much.”
