Mounting Instructions - Sony DK805AR Bedienungsanleitung

2. 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.
. Be sure to attach the stem by tightening a screw into the slot as shown in Fig. 4. Never
attach by screw threading in the φ8 hole vertical direction, pressing the stem, and then
tightening with a screw. This could result in poor sliding and low precision.
. 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").
. After the stem is secured, do not apply force in the rotational direction. This could cause
a failure.
