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 type reamer. With good runout repeatability, it is recommended that inserts be replaced without removing the shank holder from the spindle. ● Runout Adjustment J A. Simple measurement method (measure holder short taper) The short taper on the holder where the insert is mounted provides the easiest and most accurate measurement before mounting the insert. B. Precise method for measuring runout (measure insert arc-shaped land) Measuring the land immediately after the outer diameter of the insert eliminates all mounting error. This allows the most accurate runout measurement. C. Simple measurement method (measure holder outer diameter) The high-precision machined outer diameter of the shank holder provides a good estimate of the runout measurement. *A has the greatest runout accuracy, followed by B and then C. ● Runout adjustment using shank with runout adjustment mechanism (>ø35.6mm) (1) Tighten the centre locking screw to torque value A in the table below, then attach the insert and measure the runout of the cutting edge. (2) Verify the cutting edge where runout peaks and adjust with the adjustment screw. (3) Repeat this adjustment for each tooth as necessary. (4) Remove the adjusted insert, tighten the centre locking Adjustment screw screw to torque value B in the table below and then re-attach the insert.
