I have a ST-20 Lathe. 2.75' AT 7 long tool steel stock came out of chuck while turning the od. The machine now is leaving a.080 nub when facing.

So I need to rotate the turret slightly to realign it. Ive done this before by breaking loose the bolts and banging it back into place. But its my understanding these lathes have a different procedure in doing this. Ive searched all over and can't find the service manual for this machine. Can anyone give me the procedure to align the turret and/or send me the service manual? Thank you in advance! Tpractice is correct, the couplings are machined into the castings making them not adjustable.the only way to mechanically bring the tool holder back to center line is by moving the wedge or the spindle head stock squarely to each other.

Then once you're close you adjust parameter 254 to bring in your F2 x axis center line offset. Which you will need to be in debug mode to see the x-axis encoder counts under raw position screen. The x value you will need to use is the x-axis command value. Trust me I've done 100+ lathe alignments on the HL,SL, and the ST,STY,DSY lathes.

We have one on a SL-20 and it wasnt nearly as easy as it is led to believe here. If you dont do it much it will be an obstacle until you learn it. We have three HAAS machines and only the bar feeder gave us headaches, to the point we seldom use it now. As a matter of fact the guy setting it up three years ago didnt know how to set it up and run it.he was on his cell for hours and back and forth to the fax machine getting instructions.took more than a day.and he WORKED for HAAS!!!!

True it was his first time setting up that style ( i guess there are two styles kinda like brushless and brushed rotarys). That bar feeder takes up a lot of room!!! To use the bar feeder you have to set the MACROS 3100, 3101, and 3102.you access them by hitting the CURRENT COMMAND button and then the page down a few times till it shows up. Then you have to run through the training of the bar feeder by entering G105 Q4 in MDI then hit cycle start the bar will load and run through a trial run and I think measure itself.to make sure the bar in the tray will fit.

Then you press RESET and use the jog handle to push the bar o your reference position, then clamp the chuck or collet. The bar feeder has a manual.like most things once you go through it and do it alot.it becomes easier.we dont use ours much good luck bob.
