 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.
