General Mach Discussion / Re: Taig Mill not that precise Please Help
« on: July 29, 2008, 02:18:18 PM »
Hi guys
Thank you so much for your advice and help it has been much appreciated, my mill is dc servo driven so dont know about its step loss, the motors drivers just return an error and stop the motors if it misses a line on its encoder, as for the gibs i have checked out Nicks website (thank you anyway BobsShop) and followed his method and feel that they are fairly well adjusted. jimpinder im from the Uk too down in hampshire
not really up to scratch on my imperial system but i think it is 40 thousandths, not sure if its right i divided 0.01 by 25.4 and got 0.0003937 which i assume is 40 thousandths excuse my ignorance! as for the steps per unit what do you actually put in the box? 60000? my servo driver aparrantly multiplies the encoder output by 4.
For the backlash i tried your method but for some reason once set the compensation over exaggerates and continues to move into the stock the other side of the cutter and mess up the nesting design. I must say though however i do find it difficult trimming my Taig, getting the headstock tangent to the table, its a bit of a neusance the swivvel head.
RICH, i shall post some pictures soon of my jet, as i bought most of the parts and am just assembling it, i am however going to try and machine a KJ66 diffuser. ill do this and post it up, but for now i have found this great little website this guy has on making a Wren 54 turbine it shows him machining all the parts, check it out http://www.5bears.com/gt.htm
Many thanks guys for your help
Any more tips would be really appreciated!
