G.) AUTOMATIC THREAD LENGTH CONTROL
When threading into a blind hole or to a shoulder without a thread relief. The lead screw
half nut if engaged at the start of the threading work is completed. Left or right hand threads
are controlled by Control lever “D” (Figure 15), the lever is joined with the control bar “B”
(Figure 16). When the carriage touches the adjusting screw “S” (Figure 16) of the length
control bar, it will push the lever “D” (Figure 15) to “STOP” position, and make the lead
screw stop. For method of threading cut, please see Page 10, QUICK ACTING.
H.) SPINDLE BRAKE
Inverter unit “E” is used to perform dynamic braking. In addition, discharge resistor “C”
shortens braking time (Figure 17).
