Housing, Spindle, X1 Micro Mill

The spindle housing fit perfectly onto my X1 Micro Mill without any modification needed, and the machining on the mounting surfaces is noticeably clean. It feels solid and restored the rigidity I was missing.

After a year of heavy milling, the original housing finally cracked, but this replacement bolted up to the spindle with zero fuss. The machining on the bore is clean and the threads all caught perfectly. My X1 is back to cutting true again.

The fit is exact—it slid right into place on the spindle assembly without any fiddling, and the machining feels solid enough to handle the mill's daily abuse. My X1 hasn't vibrated or wobbled since I swapped it in, which is exactly what I needed.
