Page 10: Notes On Safe Operation
Basic safety instructions CAUTION Danger of limbs being crushed by opening and closing of the chuck jaws during manual loading and unloading or when replacing moving parts. • Do not reach between the jaws. • Wear safety gloves. • Observe the safety and accident prevention regulations during operation of the chuck, especially in connection with machining centers and other technical equipment. - Page 11 Basic safety instructions Functional test After installation of the chuck, its function must be checked prior to start-up. • Clamping force The max. clamping force specified for the clamping device must be reached at max. torque. • Indicator pin Never clamp or switch on the lathe when the indicator pin is protruding.
- Page 12 (clamping force, coefficient of friction, wear characteristics). (For product information about LINOMAX, see the "Accessories" section of the current SCHUNK lathe chuck catalog or contact SCHUNK). • Use a suitable high-pressure grease gun to ensure that you reach all the greasing areas.
- Page 13 • If the clamping device is involved in a collision, it must be subjected to a crack test before using it again. Damaged parts must be replaced by original SCHUNK spare parts. • The jaw fastening screws must be replaced if they show any signs of wear or damage.

Technical data 6.3.1 Calculation of the required clamping force in case of a given rpm The initial clamping force F is the total force impacting radially on the workpiece via the jaws due to actuation of the lathe chuck during shutdown. Under the influence of rotation, the jaw mass generates an additional centrifugal force. - Page 23 Technical data The required effective clamping force for machining F calculated from the product of the machining force F and the safety factor S . This factor takes into account uncertainties in the calculation of the machining force. According to VDI 3106: S ≥...

The guideway extensions (item 3) must be screwed to the bracket (item 2) using the feather keys (item 19) and all the mounting screws (item 12). -
Page 30: Maintenance
Maintenance Maintenance The item numbers specified for the corresponding individual components relate to chapter drawings.(11, Page 33) A high bearing load capacity with a secure workpiece clamping can only be guaranteed with regular lubrication using a high- performance lubricant. For this reason, we recommend regularly cleaning the chuck and lubrication using LINO MAX special grease. -
Page 31: At Least Once A Month
In this case disassemble the chuck, carefully clean all parts with degreasing agent and check for wear and damage. Replace damaged parts with original SCHUNK spare parts only. Before installation, lubricate parts with LINO MAX special grease. This cleaning procedure should be performed approx. every 200 operating hours, depending on the extent of strain on the chuck. -
