Mounting Instructions
•
Be sure to chuck the stem of the measuring unit for mounting.
•
If the measuring unit is mounted on another device, ensure that the measuring
unit is free from contact with mount screws.
•
If excessive torque is applied on the spindle when screwing in the feeler, the
internal mechanisms can be damaged. Therefore, screw in the feeler with your
hands, and never use a tool.
Except when using a flat feeler, it is recommended to either attach the supplied
spring washer (nominal size: 2.5) or use a screw lock to prevent loosening of the
feeler (tightening torque reference value: 0.05–0.06 N
·
m).
•
The measuring unit comprises ball bearings. Therefore, chucking the stem of the
measuring unit too tightly when mounting may damage the spindle and prevent
its smooth motion.
•
When mounting the measuring unit 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.
•
If the supplied installation spacers are inserted into the 1 mm/0.04" slot in
Fig. 4, tightening and securing is possible using a specified torque of 0.8 N·m.
•
When using air driving, use the fitting to be attached to the measuring unit as shown
in Fig.3. Especially, the length of the M4 screw section to be inserted into the
measuring unit should be 4.5 mm/0.18" or less. If the screw is too long, the
measuring unit may be damaged.
•
Fix the cable in a suitable position to prevent possible cable breakage. Never handle
the cable by forcibly pulling or bending it. (Inside bend radius 40 mm/1.57" or more)
•
If the spindle is to be fixed to the machine, use coupling DZ-191 which is optionally
available. Refer to the DZ-191 Instruction Manual regarding the mounting
procedure.
•
The measuring accuracy depends on the mounting parallelism. Design and
machine the mounting holder to hold the mounting parallelism of the measuring
unit to the measuring surface to within 0.02 mm/14 mm (0.0008"/0.55").
