CNC Equipment Reliability Technician

Job Description

Job Description

A day in the life

You start your shift with a quick scan of the maintenance dashboard: a 5-axis VMC shows an intermittent spindle vibration, a lathe needs a servo parameter check, and production is ramping up for a critical aerospace build. You lock out a cell, pull covers, check backlash at the ball screw, verify spindle bearings with a dial indicator, tweak a Fanuc parameter to resolve a following error, and capture the work in the maintenance log. By mid-morning, you’re calibrating a newly installed Haas, collaborating with quality on finish specs, and by afternoon you’re commissioning a router, verifying pneumatics and hydraulics, and handing it back to operations on time.
