Overview SINO-R Expansion technology
Expansion toolholder
With SINO-R, SCHUNK is offering an expansion toolholder on the basis of expansion technology. Three features make the SINO-R series unbeatable in terms of quality and productivity for thread milling: The high radial rigidity, which prevents the tool from deflecting, the higher torque transmission for full utilization of the tool's performance, and the top vibration damping for the best thread surfaces without chatter marks.
With SINO-R, you not only master thread milling:
Monoblock design of the base body for greater stability and rigidity Outstanding vibration damping Reinforced expansion sleeve for greater radial rigidity for the heaviest machining tasks with the highest radial forces
Easy tool change With the SINO-R C-spanner or spanner wrench, the tool is quickly and securely clamped.
How expansion technology works In the clamping procedure, the elastic pressure material stretches in the direction of the expansion sleeve and the tool is clamped centrically.
