Troubleshooting

Clamping force block chuck jaws will not move

Possible cause

Solution(s)

Oil supply interrupted

Check the hydraulic supply

System pressure too low

Increase system pressure according to clamping

system technical specifications

Connections mixed up

Check connections and functions and connect

properly

Hydraulic connections that are in use

are closed

Check connections and open

Clamping force block does not complete stroke

Possible cause

Solution(s)

Chips or dirt between covering strip

and base jaws

Unscrew the covering strip (item 8) and remove

chips and dirt

Clamping force getting weaker

Possible cause

Solution(s)

Clamping force block not sealed tightly Check connection and seal screws; reseal or

replace

Seals damaged

Disassemble clamping force block

(



7.4.2, Page 34)

and replace all the seals (see

sealing kit lists

Inadequate lubrication

Lubricate the lubrication nipples with LINOMAX

Clamping force block movement jerky

Possible cause

Solution(s)

Steel guide rollers on sliding surfaces

not greased

See chapter "Maintenance and Care"

(



7, Page 28)

Monitoring functions of the jaw stroke positions do not work

properly

Possible cause

Solution(s)

Monitoring pieces in the base jaws not

positioned exactly

Readjust monitoring piece for the required

function

(



7, Page 28)

Pressure change due to clamping

stroke too low

Adjust clamping stroke to the workpiece to >0.3

mm/jaw

Seals damaged

Replace seals in cover and adapter plate
