As in a previous thread, we have the A12 tool tip on our TP9-UFP get sliced/damaged at random times while picking parts. Sometimes it doesn't happen for several weeks, but sometimes twice in a day. There are enough locations for the magazines neede

You might want to check the Xwagon bearings. We had the same issue with the TP9-UFP we ordered all the possible parts Xmotors small large, encoder, transducer, couplings etc. over 10K worth of parts. The only thing we didnt order was the actual x-wag

You can leave the booster in the original position and mount two small fans directly underneanth it blowing upward. By leaving it in the original upright position you get quite a bit of air velocity in the small space between the booster and the mach

Your tool tips are being damaged because the small x-motor is not engaging when the head is picking parts. When this happens the head overshoots and you bang the tips on the mag springs. Directly after a tip gets damaged go into the service program a

We keep seeing a problem with the plastic tool tip on an A12 tool being sliced off. I think it is hitting the edge of the tape separator clip assembly - I determined this by coating the tip in paint and then finding where the tip had struck the meta

Thank you for the reply - and yes its a TP9-UFP! Problem doesnt happen all the time and may not happen for extended periods on the job where we see it most - this particular job uses all feeder slots so the head is whizzing back and forth quite a l

You dont mention if it is ONLY occuring with the A12 or is it other tools as well? Only spring tools or Stiff ones? Regardless of that, the small X Wagon motor is controlled by the track ball and the bigger X Axis motor is controlled by the joystic

Sr. Tech, youre absolutely correct that the X-Wagon (pancake) motor is the one which will do final positioning when moving to a programmed position. The X Axis motor in back of the machine is used for rapid traverse of the axis. I was thinking more

Well yesterday was uncharacteristically warm for a British summer! I always have the panel off the end of the machine at all times and certainly used to have a large desk fan blowing into it - for some reason I stopped. I had a run of strikes yeste
