Speed change
The main driving route of the machine is as follows: Motor – three groups of gears – splined
sleeve – spindle, when using a motor with 1400rpm as power, six spindle speeds from
120rpm to 1970rpm can be achieved by shifting the position of the sliding gears. Make
sure that the spindle has come to a complete stop before changing the spindle speeds, turn
off the power and turn the speed change handle to the required position.
There are two forms of spindle feed available on this machine, one is the direct feed form:
the spindle feed is performed by the drilling handle on the gear shaft directly. Under this
condition, the spindle feeds 88mm as the gear shaft turns once. The other form is the
micro feed, when the hand feed wheel drives the worm gear through the cone clutch to
drive the gear shaft to feed the spindle. The spindle will feed 2.5mm when the micro feed
handwheel is turned once.
