Mori Seiki Spindle Repair & Grinding
Mori Seiki Spindle Repair & Rebuilds
What we see most on Mori Seiki spindles: older belt-drive setups tend to come in with pulley wear and tired bearings. Newer direct-drive units usually show heat damage or preload loss. We rebuild, regrind, and rebalance across the Mori Seiki platform — SL series, NL series, older MV mills, and NH horizontals — with most jobs running 3–5 weeks and field troubleshooting where it can save a teardown.

Our Mori Seiki work covers the full lineup. Whether the job is a precision bearing pack replacement, a full rebuild, or a regrind to restore tolerance, we handle:

How We Approach Mori Seiki Spindle Work

A Recent Mori Seiki Job
A recent example of the kind of work that comes through here: one customer was ready to scrap an older Mori horizontal because of chatter. After rebuild and alignment work, it went right back into production.
