rotary bed not straight
Hi every one I think the bed that holds my rotary is not straight. when I mill near my chuck front and back are great. when I get near to my tailstock its off by about 1 mm. I am milling for jewellery so this is not good.

Hi Evonne, what mill are you using? Model Master mills were/are notorious for this sort of problem. I never use the tail stock on my MM mill. Is this a new problem?
Hi Barry its a new used machine with 4 axis. I have a old modelmaster that I used to flip manually on flat bed. With this older modelmaster I was able to set up multiple pieces to cut both sides large slab of wax.
the newer machine cant do that can only cut 1 at a time near the chuck.

Hi Evonne, put an old cutter in your chuck and then try bringing the tail-stock to the tip of the cutter. Your point on the tail-stock should be dead on to the point of the cutter. If its not you will know that the tail-stock is out of alignment. I don't know how to true the tail-stock but you might try contacting the manufacturer of the mill and ask them for assistance. Sorry I could not be of more assistance.
Hi Barry I have an adjustable tail stock I slack the screws put the tail stock, tighten the chuck around it. the tighten the screws on the tail stock. but the problem continues when cutting away from the chuck.

Hi Evonne,I think the problem almost has to be with the tail-stock (I assume you are using it).
Hi Barry I want to use it to cut large wax. right now I cut large wax on my old machine. If the adjustable tail stock point is tightened in the chuck its centre of the chuck. But when I move the tail stock to the end of the bed it cuts off by about 1mm. I think the bed itself is off.
Evonne, as noted above you probably should reach out to the manufacturer of the mill for assistance. Its the only suggestion I can make at this point.
