Flame straighten spindle? - Practical Machinist

Feb 02, 2016· Guys, I''ve got a Bridgeport 2j spindle that is bent. I can measure about 0.045 inches TIR at the top of the spindle with it installed in the quill with new bearings. This whipping action turns into a vibration when run under power with each rotation causing a stiff then loose feeling in the quill handle.

Sep 12, 2013· It''s a clone of a J-head Bridgeport and was built in 1979. So far, I''ve done a lot of small fixes to get it into good working condition. I made a new key pin for inside the spindle for the R8 collets (a real pain to get at). I replaced the brake shoes, (one had a broken off end). Removed to antique DRO, which had a dead Y readout.

CNC Mill Spindle: Bearings, Belt Drive, VFD, ATC, and

A Mazak QT-20 lathe runs 120mm ID bearings on the spindle and has a spindle bore of 2.44″. That works out to a wall thickness of about 1.142″ or about 29mm. Now let’s say we want to build a lathe spindle with a spindle bore of 2″. Let’s give it a 1″ wall thickness, so we need bearings with 4″ ID which is 101mm.
