樞軸，Z軸粗進給

Had a stripped thread on my mini mill's original coarse feed, and this replacement dropped right in without any fuss. Machining looks clean and the fitment is tight, so the whole Z-axis assembly feels more rigid now. Exactly what I needed to get back to cutting.

The machining on this replacement is spot-on, it slots into the mini mill’s Z-axis assembly with zero play. My coarse feed feels tighter and more precise than the factory unit ever did, so the whole spindle travel is much smoother now.

Swapped out the old Z-axis coarse feed center on my mini mill and this part fit perfectly, with the threading matching up exactly as needed. The machining feels precise and solid, definitely an improvement over the worn original. No issues at all during reassembly and the coarse motion is smooth and
