    2006-7-31 · I submit that 200 degrees F spindle bearing temp is excessive for a machine tool. You have to keep in mind thermal expansion and heat soak as a factor when making small precision parts. I've run many a lathe and never had the factory set spindle bearings run warmer than 40 F over ambient. 110 degrees F is hot to the touch. 20 degrees F is better.

    2012-10-1 · Hi! Let's say I have a ER20 collet with shank (shown in green). Let's say I put it into some housing (black) along with two tapered roller bearings (dark and light blue). The lower bearing rides on the shoulder of the shank. Would it be plausible to machine a fine thread onto the shank and use some kind of nut (red) to hold the construction in place and also manage preload?
