monitor. This value is to be entered in variable “B”. If the rest on mechanical stop is used the value found
(using the same method as described above – bringing the back spindle manually onto the mechanical
stop) must be increased by 1 or 2 mm before being inserted in variable “B” (E.g.: Value read on monitor
B-255.5; Value inserted in variable “B”=-254.5). The back spindle makes an exploratory stroke of the
value set in parameter “Z” (negative value) within which it should rest on the stop (at the torque set in
parameter “Y”, min. value 20, max. 50) Otherwise the machine will cut off with an operating error.
Variable “A” sets a de-phasing in degrees between the main spindle and the back spindle (used, for
example, to work on hexagonal bars).
The displacement between spindle 1 and spindle 2 refers to function M19 and is obtained by bringing
spindle 1 to M19 S0 and spindle 2 to M219 S.. (desired value); value M219 S.. for spindle 2 is to be
inserted in variable “A”
The part is gripped by the back spindle, released by the main spindle.
The back spindle jaws close, after which those of the main spindle open.
Synchronism is disabled and spindle rotation is stopped.
