For easily deformed components SMW-AUTOBLOK offers "high-low" clamping. The gripping force
of the chuck can be reduced from a large amount of gripping force used in roughing, to a smaller
amount of gripping force for a fi nishing cut.
The combination between the SIN-HL cylinder and a SMW-AUTOBLOK "high-low" suitable chuck
allows a monitored reduction in the gripping force. The component remains clamped in the chuck
safely, however, the stress of the component can be released.
The result are round components with a minimum of deformation. The "high-low" cycle is program-
mable and is finished completely within 2-4 sec.
