Hello Everyone, "My turn to go down the rabbit hole" I have a Bridgeport interact 720 with a Heidenhain 351 LE controller and all GE Fanuc AC servos. I was told that the machine had a 4th axis before I purchased it. So I felt good collecting the needed parts, I was surprised there was no servo...

720 Update When I was making some more test cuts in the air yesterday and found out it is also drifting in the X direction when cutting in the Y only axis. It will cut a square but not parallel to the table. Is there machine parameters that may be wrong or need to set to fix this problem...

Hello All, I am having problems with my 1989 Bridgeport interact 720 with Heidenhain 351/355 controller. After two years cleaning and rebuilding and creating a fusion 360 post, I think I have found why the machine was for sale in the first place. When programmatic cutting the Y-axis is...

Hello Dynapath/Baldor experts, I have been trying to get Baldor retrofit drivers and motors working on my Tree 310. The machine was not working when I got it, and I found out the mill owner/retrofitter has passed away so no information/help there. The motors have 500L encoders. All three axis...

Update, I disassembled the drawbar and found many broken washers and some bite marks on the drawbar itself (See picture). The bite marks are only about .001 - .002 deep. I have some new washers on order, and have polished out the bite marks on the drawbar. I am going to coat the washers with...

Hello, I think I have figured out my ATC tool jam problem on the 720. If the air pressure drops below 95 psi the ATC sometimes fails to load the tool holder, because the drawbar does not fully release. The drawbar air cylinder can only fully press the drawbar down at 97 or more psi. This of...

BP 720 ATC tool jam Update, I may have found out how the ATC fingers were broken. I was testing the ATC, having it load a 5/8 end mill and then put it back and then load a 3" facing cutter. I had ran this programs about 4 times changing the spindle speed each time. It was working fine, then on...
