NotE: Never clean the chuck with the compressed air. !
1. To lubricate the master jaw guideways and drawbar, apply the GLEITMO-805 grease or similar, while
for the compressed air supply system apply the HL-32 hydraulic oil or similar.
2. It is recommended to grease the jaws at least once a week.
3. Depending on operating conditions, however at least once a year the chuck should be dismounted.
All parts should be cleaned and the technical condition evaluated, any worn out seals replaced.
7.2 mounting the chuck
Prior to mounting, make sure all parts are clean and dry; the lubrication holes are clear.
To lubricate the master jaw guideways and drawbar, apply the GLEITMO-805 grease or similar; other parts
lubricate with the ŁT-43 grease.
Always tighten the mounting bolts with correct torque adequate to a bolt size and its property class.
It is recommended to replace the seals with new ones.
When mounting the chuck, please proceed in the reverse order.
NotE: Never clean the chuck with the compressed air. !
■
non-return valve cover (9),
■ pressure control plugs (12).
the following parts must be strictly secured
against unscrewing - adhesive for disjoint
connection i.e. LoctItE 243:
■ jaw clamping force,
■ control devices operation,
■ pressure drop in the clamping chamber.
check, whether the chuck is operating correctly:
■ unscrew the plug (12) and in its place screw
the pressure gauge,
■
fill the cylinder chamber with air at a pressure
of 0.5 MPa,
■
turn off the chuck power supply,
■ check, whether there is no air pressure
decrease in the chuck cylinder chamber,
■ perform the chuck leak tightness testing
operation several times,
■
testing should be performed for the two
chambers of the pneumatic cylinder.
to check the pressure drop in the clamping
chamber, please proceed as follows:
■ unscrew the control device locking screw,
■ while using a screw located inside the device,
adjust the spring tension, so that when the
pressure drops to 0,15 [MPa], the control arbor
is moved to the extreme position (such as when
there is no pressure in the chamber),
■ screw in the control device locking screw,
■ testing should be performed for the two
chambers of the pneumatic cylinder.
to adjust the pressure control distributor in the
chuck pneumatic chamber, please proceed as
follows:
NotE: Insert the jaws into the guideways marked with the same number. !
