手輪，Z軸粗進給鎖定，細進給嚙合

Finally tightened up the slop on my mill's Z-axis. The lock engages with a crisp feel and the fine feed is instantly usable. No more guesswork on delicate cuts.

After fighting with the old sloppy handles for months, this replacement locks down tight and engages the fine feed with a positive click. The coarse feed no longer drifts when I'm trying to make a precise adjustment.

Was a bit skeptical about how well the locking mechanism would work, but it engages the fine feed knob smoothly and holds tight without any wobble. The lever’s action is crisp and solid during use. Exactly what my bench mill needed.
