The indexing angle of the connecting arm of the accessory shall be adjustable. 3.2 Electrically operated accessories (seeFigure 1) When the accessory is located by means of an automatic changer, the transmitter arm projecting over the sensor is in line with

17、the receiver module. The receiver module is inserted in the connector block which is located on the spindle holder. The dimensions are given inTable 1. The functional connecting dimensions are the centre distance S and the distance C 1between the face of the transmitter module and the gauge plane of

18、 the shank. 3.3 Coolant feed accessories (seeFigure 2) When the accessory is located by means of an automatic changer, its end is inserted in the corresponding hole or slot in the connector block which is located on the spindle holder. The dimensions are given inFigure 2 andTable 1. The initial posi

19、tion of the end of the accessory shall not overlap the top face of the flange and the travel of the end shall be sufficient to ensure good connection with the receiver of the connector block. The functional connecting dimensions are the centre distance S, the distance C 2between the face of the end
