Problem- Workshift on Hardinge vs. Takisawa

[gtrrpa]

I ran a Hardinge gang tool conquest GT 9 yrs. ago. The way they set work shift was from the front of the toolholder to the front of the spindle nose and entered that as workshift Zero and measured tools? I can't exactly remember the sequence, but it was somewhat crazy to me. My question is I am having a Conquest GT 27, Fanuc Series 21-t control panel gang tool being delivered next week. I am used to putting stock in collet taking face cut with turning tool call that workshift ZO and ZO geometry all my tools from that face and I'm ready to rock and roll. That's safe to do that on Hardinge ain't it? It's your program Z0 ! Please let me know..Been doing it on Takisawa's for the last 8 yrs. and no problem. Let me know. Thanks ahead of time....

I have zero experience with that lathe, but we have several lathes with the 21i-T control. (Not on gang lathes, tho.) Seems like it should be sensible to face with a tool having Z0 geometry, set your workshift, and then set the Z-geometry for the rest of the tools by touching this face. Just like you stated. Then adjust the workshift as needed.

Our gang lathes all have Fagor controls. There is no workshift. You face with a tool, call it Z0, touch the rest of the tools to this face calling each Z0. If you have to move in .01, then the offset for each tool has to be changed by that much. Which is why it is better to remove the part, and take a measurement so you know how much has to come off. Then instead of using Z0, you would use Z plus the amount coming off. Example: say the part needed another .022 removed from the face. The first tool (and all others) would require Z.022 input. Then you wouldn't have to move each tool offset .022 later.

I knew it was different, just had to remember.What you have to do on a gang tool is Z0 the face of the faceplate to the end of your work.(call that Z0 on your workshift page).You can use a shim,but add that shim to your workshift as a positive # when entering it in your work shift Z work****.EX: If you are using a 2" jo block, jog,then manually bring the tooling plate so that it is snug to the block.(NOT THE DOVE TAIL SURFACE) but the suface that is 90* to the toling plate. Enter 2" once you get a snug fit between these two surfaces and enter 2.0 into your Z workshift. Your # will be a Neg. number.From that point measure all your tools using the same shim be sure to adding 2" to your Z geometry and select measure.You can probably get away with just going to each tool to stock and enter Z0 Measure.I believe Hardinge does this due to a safe index position measuring your longest tool exceeding from the end of the tooling plate.
