SumiReamer SR Reamer
■ SR Reamer Usage Instructions (Adjusting Runout) The runout at the cutting edge of a reamer should be zero to obtain optimum boring precision. To correct runout in the holder or the machine's spindle, use of holders with a runout adjustment mechanism, hydro chucks and shrink-fitting is recommended. Various methods can be used to measure runout on a SumiReamer SR Reamer. With good runout repeatability, it is recommended that inserts be replaced without removing the shank holder from the spindle.
● Runout Adjustment
Procedure: 1. Secure central clamping screw according to value "A" in the table (if no value is listed use value "B"). 2. Load the tool into the machine spindle. 3. Set the indicator (with 1 µm / .0001 inch resolution on the marked run out ① area on the shank. 4. Measure run-out of the two adjustment screw ② axes. Compensate half the value of the total run-out error by using the adjustment screws. Check run out on all four axis points and repeat the adjustment if necessary. Tighten all adjusting screws, and verify run-out of .005 mm / .0002"" T.I.R. or less. 5. Tighten the central clamping screw according to the value in table "B". 6. Check the run out again and readjust if necessary.
