برغي تغذية، محور Y لمطحنة SX2 الصغيرة، 20 سن/بوصة

The 20 TPI threads are noticeably finer and smoother than the original, making Y-axis adjustments much more precise. Installed it in under an hour and immediately got better control on my mini mill.

The threads are cut clean and true, so the carriage moves without any binding or backlash once I set the nut properly. Swapping in this 20 TPI screw made fine adjustments on the Y-axis noticeably more precise than the stock thread.

Installed this on my mini mill and the 20 TPI threading makes fine adjustments much more precise than before. The screw itself feels nicely machined and slides smoothly through the brass nut.
