TRM-N series 2* ELECTROMECHANICAL VERTICAL AXIS TURRETS TOOLHOLDERS CLAMPING DIN 69881-1 TRM-N / series 2* INTERNAL KINEMATIC MOTION A) Electric motor (three phase) B) Reducing gearbox C) Rotation and cam locking mechanism D) Indexing solenoid E) Indexing control switch F) Preloaded locking springs G) Front coupling H) Locking control switch I) Position proximity switches L) Tool post M) Coolant valves (optional) TRM-N / series 2* CYCLE DESCRIPTION 1. – Signals To get a change of positions on the TRM-N turrets, the control equipment (usually a N.C. equipment) must control the components mentioned below according to a well defined sequence (see wiring diagram on page 14). • Motor (1) • Indexing solenoid (3) The following signals from the turret are provided for the driving of the positioning cycle: – Angular position given by the proximity switch (61,62...) – Indexing control switch (4) – Locking control switch (5) 2. – Description of the operating sequence This description refering to the diagram on page 15, gives the sequence to pass from position 1 to position 4 with counterclockwise rotation. As indicated by the cycle on page 15 the controls are to be performed according with the following sequence: a) Starting of motor rotation in the unlocking direction b) The turret disc rotating, when the proximity switch (6) of the pos.4 gives the signal, energize the solenoid (3). N.B.: Between the reading signal and the energizing of the solenoid (3) the maximum lag time have not to exceed the value R1.
