I had to be honest and admit I had never taken one apart to investigate. Taig products are so well built there was never a need to disassemble the spindle.<\/p>\n<p>The new\u00a0spindles\u00a0are different than the older versions. The new ones have the cartridge\u00a0insert\u00a0from the end. It slides into a machined bore. The old heads have a split case. The pictures here are the old head. Both hold the cartridge in place with a recessed screw into the center portion of the cartridge.<\/p>\n<p>I wasn&#8217;t and still not interested in pushing apart one of my ER spindles to view the cartridge. There may be no harm, but if it isn&#8217;t broke now, why look for a problem? The old split case is no problem. The side will almost fall off when the bolts are loose. Probably the reason for the change to the new style.<\/p>\n<p>At first look it\u00a0appears\u00a0to be four bearings. The center section is not bearings (as far as I can tell). The end bearings are compressed against the center core providing proper bearing pre-load. The pre-load nuts are on the outside against the bearing case. The center section is under compression.<\/p>\n<p>To me it looks like a very elegant design and has been trouble free. First class machining, not like the cheap imports. It HAS to be to run at 10,000 rpm. That doesn&#8217;t imply all imports are cheap but few are rated for that kind of speed.<\/p>\n<p>So I suppose you could make your own spindle case if required. I run the spindle at 10,000+ rpm all day with no heat buildup (after initial\u00a0break-in). Perhaps the cartridge could be pushed faster with bearing cooling. However, for the novice there are other requirements like dynamic balance. There is a lot of mass there.<\/p>\n<p>I read the &#8220;speeder&#8221; 30,000 rpm spindle adapter on the Tormach machine is really rated to 20,000 rpm. Even then, they have had to resort to <strong><a title=\"Speeder\" href=\"http:\/\/www.tormach.com\/blog\/?p=1107\" target=\"_blank\">dynamically balanced<\/a><\/strong> ER16 collet nuts to run at that speed. Experimenters beware.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I had an\u00a0inquiry about how the Taig Spindle could be taken apart and the cartridge used elsewhere.
