Spare parts
Use of unauthorised spare parts
Using unauthorised spare parts can endanger personnel and
damage the product or cause it to malfunction.
• Use only original spare parts or spares authorised by SCHUNK.
Chuck jaws
Requirements of the chuck jaws
Stored energy can make the product unsafe and risk the danger of
serious injuries and considerable material damage.
• Only replace chuck jaws if no residual energy can be released.
• Do not use welded jaws.
• The jaws should be designed as light and as low as possible.
The clamping point must be as close as possible to the chuck
face (clamping points at a greater distance lead to greater
surface pressure in the jaw guidance and can significantly
reduce the clamping force).
• If for constructional reasons the special chuck jaws are
heavier than the top jaws assigned to the lathe chuck, greater
centrifugal forces must be accounted for when defining the
required clamping force and the recommended speed.
• The maximum recommended speed may only be operated in
conjunction with maximum actuating force and only with the
lathe chuck in optimal, fully functioning condition.
• After a collision, the lathe chuck and the chuck jaws must be
subjected to a crack test before being used again. Damaged
parts must be replaced with original SCHUNK spare parts.
• Screw the jaw mounting screws into the bore holes furthest
apart.
• The jaw fastening screws must be replaced if they show
any signs of wear or damage. Only use screws with a quality
of 12.9.
