SEMI-AUTOMATIC THREADING
The compound slide is fitted with a sub slide, which is
actuated hydraulically in the cross-movement (Y-axis).
This essentially moves the tool post away from the work
piece upon actuation of the hydraulic cylinder.
The system is set up using electrical micro stops both on
they X-axis and Y-axis.
The Omron microprocessor control is programed to perform a
'box cycle' operation. By use of a toggle switch on the
control panel, a "continuous" or "single" box cycle can be
selected. A second toggle switch selects Position I right
hand thread internal/left hand thread external; Position II
left hand thread internal/right hand thread external.
The depth of thread is determined by the operator, putting
on the cut during the retracted part of the cycle.
The angle of taper is determined by the heavy-duty "fully
jibbed" taper turning attachment.
The reversal of the apron is accomplished by lead screw
reversal and a one-postision clutch in te feed box
assembly. This ensures there will not be any pitch error
in the manufactured thread, which can occur on lead screw
disengagement systems offered by some manufacturers.
