I have a Patriot VFD purchased in May. Have made many of the mods to eliminate vibration as well as upgrades I have made from ballscrews, new brackets and mounts for steppers and so forth.
I have converted it to total cnc, with 16" travel in Y as well. still don't have 4" travel in Z as advertised only 3.5" ? "scratching head"
I would like to see the conversion for 16" travel- as far as the quill travel, its actually sort of unlimited- without the front set screw that rides in the machined groove , the quill will continue to travel until it comes out of the casting. Maybe the groove was not milled enough and is restricting your travel.
My problem is this. How the heck do you adjust the lathe spindle to make it parallel to the X ways? It is off by 0.011 and this is causing a tapering of approx 0.001 for every inch of travel along the axis. It makes for useless shafts if you know what I mean
The lathe column is held in place with 4 big bolts and on each side of the column between the bolts is a taper pin. The taper pin is threaded so you can screw in a bolt and pry it out. You can pull out the taper pins and loosen the bolts and move the lathe spindle into alignment by tapping it with a rubber mallet. Once aligned, you can re-tighten the four big bolts. However, putting the taper pins back in could return it to its original position, so you would need to ream the holes first.
I know there are two mounting screws on each side of the base to head mount. What I'm not sure of is the center pins? They are threaded internally?
I know that most mating surfaces on this have location pins which I have had to remove in order to get things indicated in. Now I must tackle this as the last hurdle.
Anyone know the procedure for this machine?
Thanks in advance.
