The following description was provided: ================================================================= Here is my technique for creating rounded bar links (and other work) using a rotary table. rotary_table_1 Here are the "raw materials". My workpiece which is rough-bandsawed oversize to reduce the amount of stock to be removed with the milling cutter. The centerlines have been jig-drilled using the x-leadscrew onmy Bridgeport mill, first with a center drill, then a 1/8" drill bit. Other raw materials are R8 collets with a stub of 3/4" CRS round stock, and a stub of 1/8" drill rod. rotary_table_2 Here is the basic setup for centering the rotary table. The 3/4" CRS stub is tightened in the mill's spindle, and the center bushing of the rotary table is located with the X and Y leadscrews, until the stub slips cleanly into the bushing when operating the quill. At this point, the spindle is centered over the center ofthe rotary table. rotary_table_3 Without moving the table from the photo above, put the workpiece on a parallel and locate the hold-down clamps with finger-tight bolts. Insert the collet with the 1/8" stub and then lower the quill into the drilled hole on the workpiece. Now it is time to tighten the hold-downs with a wrench. Using either X or Y leadscrews, move the table an amount equal to (radius of link end) + (radius of milling cutter). You are ready to cut the radiused end. rotary_table_4 Finished workpiece after some other operations compared to the drilled blank. Matt Isserstedt 02 March 2003 matt.isserstedt@gm.com
