Description With SINO-R, SCHUNK is offering an expansion toolholder on the basis of expansion technology. Three characteristics make the SINO-R range unbeatable in terms of quality and productivity when it comes to thread milling. The high radial stiffness, which prevents deflection of the tool. The higher torque transmission that allows the tool to be used to its full potential. And the top vibration damping that produces the best thread surfaces with no chatter marks. Field of application Universal! For thread-milling and for volume machining with torques of up to 800 Nm Advantages – Your benefits Monoblock design of the base body For increased stability and rigidity, the base body is made of one steel block from the toolholder taper right up to the machine mounting Peerless combination of a monoblock design, multi-layered structure, and thicker walls Perfect thread with increased ease of operation and longer durability without wear 100 % increased tool life By avoiding micro-blowouts on the cutting edge Optimal ratio between clamping force, rigidity, and damping This ensures reduced tool costs and more efficient production High torque and velocity When clamped, the tool transfers torques of up to 800 Nm (tool shank Ø 32/shank quality h6) High degree of flexibility Due to the use of intermediate sleeves Easy tool change Minimizing set-up times and costs Exact axial length preadjustment All commercially available tool shank types can be clamped Options and special information Three features make the SINO-R series unbeatable for thread milling in terms of quality and productivity: The high radial stiffness, which prevents deflection of the tool. The higher torque transmission that allows the tool to be used to its full potential. And the top vibration damping that produces the best thread surfaces with no chatter marks. These are what the peerless combination of a monoblock design, multi-layered structure, and thicker walls can give you.
