進給螺桿，Z軸 X1 微型銑床

Installed this Z-axis screw on my X1 micro mill last weekend, and the threads mesh perfectly with the nut right out of the box—zero binding during the first few test passes. The fit is noticeably more precise than the original part it replaced.

The threads on this Z-axis screw are cut perfectly smooth, which made swapping out the old one on my micro mill a quick job. It rotates with just the right amount of resistance now, no binding at all.

The threads on this replacement screw are machined perfectly, which made installation smooth and precise on my X1 mill. My Z-axis moves more consistently now.
