I am "repairing" ( not rebuilding or restoring) an Aciera F4 milling machine.
It has seen some abuse in its life, having been either tipped over, or hit by a forklift or something similar.
That damage is pretty straight forward repair work. The worst of the abuse has resulted from incorrect lubrication practices. This machine has zerk fittings for oiling, but someone has tried to grease it. This has resulted in some scoring of the longitudinal ways. Fortunately the other ways have not been damaged.
You will see from the pictures the extent of the damage. the worst I can reliably measure is aproximately 0.010" deep, with the most of it between 0.002 and 0.005" deep.
I have been considering several options;
1) Machine it clean, and install Turcite to bring the slide back to the original height,
2) Scrape the slide ( this will cause some dificulty with lead screw alignment),
3) use "scorex" ( a moglice product) this will necessitate grinding grooves in the way to provide adequate material thickness.
4) scrape the way flat, ignoring the divots and consider them "oil pockets".
I am leaning very hard toward option 4. the original scraping is still visible on the majority of the slide and I believe a little judicous scraping, and stoning will be adequate.
I am looking for options. any advise considered and appreciated!
