Mounting Instructions - Sony DK50-Serie Bedienungsanleitung

2. Mounting Instructions

. Be sure to chuck the stem for mounting the measuring unit. If other portion of the measuring
unit needs to be chucked, avoid chucking the name label portion (where the head is built
in) and its neighborhood (Fig. 1).
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 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.
. A holder of dimensions as shown in Fig. 2 may be used to mount the
measuring unit, tightening the screw to about 4 N.m torque.
. Since mounting parallelism affects the measuring accuracy, adjust the parallelism to within
0.3 mm in relation to 100 mm displacement by means of mount bracket (or sleeve).
. 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 50 mm 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.
. After the stem is secured, do not apply force in the rotational direction. This could cause
a failure.
