Commissioning
Check that the jaw guides and the piston of the ROTA B-type
power chuck are sufficiently lubricated at the lubrication nipples
set into the base jaws; if not, relubricate LINOMAX acid-free
grease with the base jaws in the retracted position. When the
chuck is dried out, the clamping force is significantly reduced.
A locking screw with a hexagon socket is located on the front face
side of the chuck. Behind the locking screw, the pilot-controlled
non-return valve controls the pressurization and venting of the
two pressure chambers and blocks the pressure from the outside.
It is very important that the bore hole of the valve system be
lightly lubricated with oil so that the valve system can move easily.
Too much grease lubrication and dirt in the valve bore hole will
significantly impair the function of the chuck and should be
avoided.
CAUTION
When actuating the clamping device (clamping or releasing),
allow a short pause for ventilation between each shifting
operation. This ventilation pause must be at least 0.5 seconds,
depending on the length of the hose. We recommend using a
4/3 or 5/3 directional control valve for this (center position
depressurized).
CAUTION
Facing or skimming of the pneumatic power chuck is not
permitted. Drilling of the chuck on the front face side may be
performed only in accordance with the drilling patterns on the
SCHUNK dimension sheets.
