Thread: FP1 Accident

Bit bummed, first accidednt on my FP1.

I was boring a hole in a part...after a no. of passes ( I was using the auto feed on the vertical) I stepped away to do a quick caculation on paper (I know dumb of me) and the boring bar shoulder hit the part. By the time I got to the machine the part was wobbling and loosend in the vise (kurt). You guys think I did any damage, and if I did, how should I assess it. Same goes for the boring head (a Narex).

By the way, between the boring head, Kurt 6" vise, and the boring bar the max aperture available is only about 2-3 inches. After putting a part in, that protruded about 1.25" no room to actually take measurments without disturbing the set up.

Regards, Vinay

Turn the vertical had 90* and run the boring head feed parallel with the "X". Or pull the table and fixture the part lower on the face of the vertical slide table mount.
Turn the table (if you have the universal swivel table) 90* and run the part using the horizontal spindle...turned table allows part to be placed well away from the spindle.

As to damage...if backlash is the same as before the crash and the shear pin is intact and installed correctly(assuming the pin was made from proper mild steel as per the drawing in the manual) I would check the tram of the vertical head/table (if universal).....
If all the noises are normal them most likely no worries....

Thanks Ross.

I will check out your pointers. The one was that I had locked the x and y axis. Wonder if that helped or hurt,
