SINO-R

SINO-R

Expansion Toolholders
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 prevents deflection of the tool. The higher torque transmission allows the tool to be used to its full potential. And the top vibration damping produces the best thread surfaces with no chatter marks.

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
  • Reinforced expansion sleeve for increased radial rigidity
    Very difficult metal cutting tasks with the highest of radial forces
  • Optimum ratio between clamping force, rigidity, and damping
    Reduced tool costs, more efficient production, and high torques up to 800 Nm in clamped condition
  • Excellent vibration damping
    Micro-blowouts are prevented, best workpiece surfaces, machine spindle protection, increased tool service life resulting in cost reductions
  • High degree of flexibility
    Clamping of different diameters due to the use of slotted or coolant-proof intermediate sleeves
  • Easy tool change
    Minimization of set-up times and machine downtimes through fast and safe clamping of the tool by means of SINO-R C-wrench or ring-shaped clamping key
  • All commercially available tool shank types can be clamped
    Form A: with smooth cylindrical shank, shank form A in accordance with DIN 1835 and DIN 6535 HA Form AB: with flat face and cylindrical shank with pulling face, shank form B in accordance with DIN 1835 and DIN 6535 HB Form B: with lateral pulling faces, shank form B in accordance with DIN 1835 Form E: with inclined clamping face, shank form E in accordance with DIN 1835 and DIN 6535 HE
  • Axial length adjustment
    Length adjustment in the range of 0.01 mm accuracy, with adjustment travel of 10 mm

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.
