Hi Folks
After many hundreds of hours machining aluminium and plastic we need to replace the Delrin nuts on the X and Y axis of our little Chinese 3020 CNC machine. :cool:
Anyone on the forum know if or where these can be obtained?

Hello,
Have a look on ebay as i know there is one seller in the UK that has them for sale in dif combinations, I know for sure they do the same screw and a matching Tap, so you could make your own if you wanted to buy the Tap? I do have a ACME tap but i dont think its the right size will go and have a look now...
EDIT:
Try contacting this seller: Trapezoidal ACME Leadscrew & Nut - TR8x1.5 TR10x2 TR12x3 TR16x4 - 3D Printer CNC
They may be willing to sell you just the nuts :).

You tried contacting the original seller? they usually stock spares.
What diameter do you need them? I've got a 12 x 3 tap and some 25mm black or 30 (something) mm delrin rod so could make some for you?
Have you had a look at this thread on making your own. I'm about to try making delrin nuts for my Chester 16v mill using this technique

As far as i can determine, delrin and acetal are pretty similar (maybe delrin is just a trade name for acetal ?)
Tom, don't!
the forces on the chester are much larger than on the 3020. Stick with your ballscrew idea and use backlash comp in Mach3/4
Many thanks for the link Lee! Will give them a bell and see what happens. :)Quote:
