Description
Applications & Features Depth control Top will advance 0.140'' ±0.004'' after machine spindle travel stops. Example: to achieve a top depth of 1.000'', set spindle stop at 0.860'' will advance an additional 0.140'' to 1.000'' depth NC Machine Set torque as high as possible within safe limits of the top. NC machine cutting feed equals (top pitch x spindle RPM). Reverse feed equals 2 X (top pitch X spindle RPM). Tapping Capacity in Steel: 0-1/4"(M2-M7) Jacobs Taper : J-6 REC.
