Two things missing from most annual lists that have bitten us:
1. Encoder battery replacement. Absolute encoders (Fanuc, Mitsubishi, Yaskawa) have lithium backup batteries that keep the multi-turn counter alive. They're rated 3-5 years but I've seen them die at 2.5 years in hot environments. We replace every 2 years on a fixed schedule regardless of voltage reading. A dead battery means you lose your home position and need to re-reference everything — that's a 4-hour job minimum on a complex die setup. The battery costs $12.
2. Brake holding torque test. The slide brake is your last line of safety defense. Once a year we do a static holding test: position the slide at mid-stroke, apply rated tonnage with a hydraulic cylinder, release the motor, and verify the brake holds for 60 seconds with zero drift. If it moves even 0.01mm, the brake disc gets replaced immediately. We log the results — trending helps you predict when a brake is starting to wear before it actually fails.
For the holiday shutdown approach — totally agree but add one thing: run the press for 30 minutes under no-load after reassembly before you put a die in it. Thermal expansion from cold start will shift your BDC by 0.02-0.05mm depending on press size. Let it stabilize, then verify your settings.
