Mounting Instructions - Sony DG805BLM Instruction Manual

2. Mounting Instructions

. Be sure to chuck the probe stem for mounting.
. When mounting the probe, secure it in such a way that mounting screws do not contact it
directly.
. Use of a nominal 2.5 spring washer is recommended to prevent loosening of the feeler.
However, the spring washer does not need to be used for flat feelers.
. The probe employs ball bearings in it. When mounting the probe, therefore, be sure not to
fasten the stem too tight lest the balls should grip the spindle and prevent smooth motion.
. When mounting the probe on a machine by using a holder, prepare the
holder with dimensions and material shown in Fig. 4, and fix the probe by
fastening a screw with a specified torque of 0.6 N•m.
Use the fitting to be attached to the gauging probe as shown in Fig.3. Especially, the
length of the M4 screw section to be inserted into the gauging probe should be 4.5 mm/
0.18" or less. If the screw is too long, the gauging probe may be damaged.
Note
The measuring accuracy depends on the mounting parallelism. Design and machine the
probe holder to hold the mounting parallelism of the probe to the measuring surface to
within 0.3 mm/100 mm (0.01"/3.94").
. Fastening torque of the measuring feeler: 0.05 to 0.06 N•m.
