22 Direct Adjusting Boring Bar Principle The adjustment mechanism is work by pushing the micrometric adjustment screw after the insert screw has been tighten, there is no backlash while adjusting boring diameter. Procedures of Setting Boring Diameter 1. Turn screw-2 clockwise to the bottom end before tighten the insert. 2. Tighten the insert by screw 1. (If you have tool presetter, follow step 3-5; if you don t, jump to step 6-9.) Slide wedge Micrometric adjustment screw Insert lock screw Insert 3. Put the boring bar on the spindle of the tool presetter. 4. Measure the diameter of the boring bar by tool presetter; it should be smaller than nominal diameter. Adjusting the diameter of the boring bar by turning screw-2 counter-clockwise using the Allen-key to increase diameter until required diameter is achieved. 5. If the diameter has been adjusted too big, please loosen the screw-2, and then screw-1. Repeat step 2-4 until the required diameter is achieved. 6. Put the boring bar on the machine spindle and make a test cut, about 5 mm deep. Measure hole diameter of the test cut. Screw-1 Screw-2 7. Moving the boring bar to the tool diameter setter. The insert of the boring bar should touch the ceramic probe gently. Setting the dial gage to zero and adjust diameter by turning screw-2 counter-clockwise using the Allen key. 8. Read and note the Adjusting amount on the dial gage. Adjusting amount=(nominal diameter-test cut diameter)/2 (mm or inch.) 9. Make test cut and measure again until required adjusting amount is achieved. Adjusting Range 0.2 mm Adjusting boring diameter on the presetter.
