Examples for assembly Open center with VNK-T2
Partial open center with SIN-S / SIN-HL
High-low clamping for thin-walled components
Principle
For easily deformable 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 finishing cut without unclamping the component.
The SMW-AUTOBLOK closed center cylinder type SIN-HL and a modification of the machine hydraulic are necessary.
Solid component / high gripping force
Thin-walled component / low gripping force
Function
In combination with a SMW-AUTOBLOK ”high-low“ hydraulic cylinder SIN-HL and suitable machine hydraulics, the KNCS-NB / KNCS-NBX wedge bar system allows a monitored reduction of gripping force. The component remains clamped in the chuck, however, the stress of the component can be released. The ”high-low“ cycle is programmable and is finished completely within 2 - 4 sec.
