16、lying with ISO7388-1 and ISO7388-1/Add.1. 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
20、and the end the gauge plane, and the diameter (18 mm) of the end. 0,032 0,050BS6607-4:1994 2 BSI 08-1999 Figure 1 BS6607-4:1994 BSI 08-1999 3 3.4 Mechanical indexing accessories (seeFigure 3) When the accessory is located by means of an automatic changer, its end is inserted in the corresponding hol
