Basic safety notes

Intended use

This product is intended for clamping workpieces on machine tools

and other suitable technical devices.

• The product may only be used within the scope of its technical

data, (3, Page 17).

• The product is intended for industrial and industry-oriented use.

• Appropriate use of the product includes compliance with all in-

structions in this manual.

• The maximum RPM of the chuck and the required clamping

force must be determined by the user for the respective clamp-

ing task based on the applicable standards and technical speci-

fications of the manufacturer.

(See also “Calculations for clamping force and RPM” in the

chapter “Technical data”). (3, Page 17)

Not intended use

A not intended use of the product is for example:

• It is used as a press, a punch, a toolholder, a load-handling device or

as lifting equipment.

• the product is used for unintended machines or workpieces.

• the technical data is exceeded when using the product.

(3, Page 17)

• if workpieces are not clamped properly, paying particular at-

tention to the clamping forces specified by the manufacturer.

• if it is used in working environments that are not permissible.

• if the product is operated without a protective cover.

Constructional changes

Implementation of structural changes

By conversions, changes, and reworking, e.g. additional threads,

holes, or safety devices can impair the functioning or safety of the

product or damage it.

• Structural changes should only be made with the written ap-

proval of SCHUNK.

Spare parts

Use of unauthorized spare parts

Using unauthorized spare parts can endanger personnel and dam-

age the product or cause it to malfunction.

• Use only original spare parts or spares authorized 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 centrifu-

gal 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.
