  • Page 11 (clamping force, coefficient of friction, wear characteristics). (For product information about LINO MAX, see the "Accessories" chapter of the SCHUNK lathe chuck catalog or contact SCHUNK). • Use a suitable high-pressure grease gun to ensure that you reach all the greasing areas.
  • Page 12 Basic safety notes accounted for due to the centrifugal force acting on the chuck jaws. The operating clamping force must in this case be determined by means of dynamic measurement. • Move the clamping piston through to its end position several times after 500 clamping strokes, at the latest.
  • Page 13: Substantial Modifications

    • If the chuck is involved in a collision, it must be subjected to a crack test before using it again. Replace damaged parts with original SCHUNK spare parts. • Replace the chuck jaw mounting screws if there are signs of wear or damage.

  • Page 22: Chuck Function

    Chuck function Chuck function The item numbers specified for the corresponding individual components relate to chapter drawings.( 12, Page 30) Functional principle The HSA compensation chuck in wedge-hook design is actuated by a rotating solid or through-hole cylinder. The axial tensile or pressure forces are converted to the radial jaw clamping force by the wedge hook angle in the piston and base jaws.
  • Page 23: Replacement Or Renewal Of Jaws

    Chuck function Replacement or renewal of jaws Chuck jaws for maximum repeat clamping accuracy must be turned or ground in the chuck under clamping pressure. Self-centering clamping (see drawing) must be selected in this case. • When turning or grinding, ensure that the turning ring or turning pin is clamped by the top jaws and not by the base jaws.
  • Page 24 Chuck function HSA-NZ 170/2 • Remove all screws (Item 26) and then remove the center (Item 16). Unscrew the screws (Item 18) and remove the cover (Item 13). Then unscrew further screws (Item 18) and remove the guide bushing (Item 4). •...
  • Page 25 Only use genuine SCHUNK spare parts when replacing damaged parts. The chuck must be completely assembled, including all the small components, before start-up. Each small component may have a safety function in the chuck.
  • Page 26: Maintenance

    Lubrication To maintain the safe function and high quality of the chuck, it has to be regularly lubricated at the lubrication nipples. Use SCHUNK LINO MAX special grease for this purpose. • For optimum grease distribution, the clamping piston must travel the entire clamping stroke several times after lubrication.
  • Page 27: Disposal

    • Remove any identifiable plastic or aluminum parts installed in or on the chuck and dispose of them properly in line with the statutory provisions. • Dispose of the chuck's metal parts as scrap metal. Alternatively, you can return the chuck to SCHUNK for proper disposal. 01.00| |en...
