palmgren rotary table quotation

Palmgren’s rotary cross slide tables have precise rotary, lateral and transverse feeds for rapid positioning of the workpiece. Bolted to a machine these tables increase your ability to mill, route, shape, cut slots and keyways, as well as grind. Intricate jobs become easy on metal, plastic, composites or wood.

Palmgren’s precision built slide tables are perfect for inspection, layout, and machining operations. They offer counterbalanced ball crank handles for rapid, accurate positioning and precision indicators and dials for a variety of applications along multiple axes. A wide variety of options including slide, milling, rotary, cross slide, and rapid indexers provide versatility and remarkably precise operation for any application including milling, drilling, layout and grinding.

A couple of things to look for. First, the worm adjustment may not be locked down. Or if it is, it may be too tight in places on the worm gear. It"s not the cleanest or best arrangement for a rotary table. Next, make sure the hold down or table locks are loose and not snug or tight. They will bind on you occasionally if your not careful. Also, if they are missing, the pieces under the top on the RT may still be there. And last, yeah, just like everyone else is saying the method of securing your part to the table is flexing the table top. The table top is so thin, it wouldn"t take much to cause it to flex. It"s expected from something from Palgrim.

My suggestion is get you a piece of aluminum plate about 7-8" square or diameter by about 3/4-1" thick. Machine it flat, unless it is tooling plate that has been ground flat, and mount at the outer edges with hold down bolts. Next drill and tap a field of holes on 1" x 1" grid on the plate. This will allow you bolt down just about anything with out worrying about the table top flexing. Plus, if you bugger up the surface of the sub table, you can re surface it or replace with a fresh top. Ken
