7 General Safety Instructions
1. Safety requirements to machines
-
Operation of the machine spindle is only allowed, when the clamping pressure and clamping
force is in the acceptable range. (Operating with a pneumatic cylinder)
-
Do not rotate the spindle without a workpiece clamped.
-
On a breakdown of the clamping power a signal must stop the machine spindle and the
workpiece has to be clamped till a complete stop of the spindle.
-
After a power breakdown and on return of the power, a changing over must not occur.
-
During operation, the spindle and the clamped workpiece must be secured by a safety facility.
-
The opening of the safety doors is only possible if the machine spindle stands still.
-
All operations and maintenance to the spindle and the tool-gripper are only allowed if the
spindle stands still.
-
Make sure, that during operation no force impacts on the lever. A lever under pressure
increases friction between the chuck and the bearing jaws which leads to increased wear and
the chuck runs hot and gets damaged.
-
Regrease / lubricate the bearing jaws / curved rollers regularly.
2. Operation cylinders, machine spindles
To operate the collet chucks, please use only appropriate cylinders according the safety and
accident preventions regulations. Mounting the collet chuck to a spindle with an existing operating
cylinder, make sure that the clamping power is sufficient to clamp the workpiece and the maximum
clamping force is not exceeded! Connection parts and adapters must be designed to endurance
strength. Set and check the limit switch to check the stroke before initial operation.
3. Operating data
The allowed operating data, maximum clamping force and maximum revolutions shown on the
technical data sheet (see: Technical data p.14) may not be exceeded. The minimum clamping
force depends on cutting rates.
4. Collets
Please use solely suitable steel collets and Rubber-Flex® collets according DIN 6343, matching
your chuck (see: Technical data p.14).
