Introduction of supERgrip SGER power ER collet chucks:

supERgrip SGER is the power version of ER collet chucks,It is a new generation ER collet chucks.

supERgrip SGER redesign the structure of clamping part:
  • The contace area for ER collet taper is increased by 30% more
  • Enlarge the O.D. of the thread part and increase the pitched of thread contact
  • It will increase the contact area of thread part by 50% more
  • We adopt the nano surface treatment ball bearing nut
  • It will reinforce the clamping torque by 50% more

The combination of innovation reinforce the clamping torgue for 100% more.
We also redesign the outline,It reinfoce the rigidity by 50%.

The great thing is

Your DIN6499B/ISO15488B ER collets using currently will be able to use on supERgrip SGER power ER collet chuck.
It will upgrade the performace by just upgrade the collet chuck.
ER collets on supERgrip SGER power ER collet chuck will have 0.25 mm collaspe.

We also add the design of balanceable thread holes,You may do the balance after the tool is assembled.
This innovation collet chucks are called SGER series.

          MORE CONTACT AREA                        MORE THREAD CONTACT         NANO BALL BEARING NUT      MORE RIGIDITY WITH NEW OUTLINE

Technical information of SGER collet chucks:

  • Material: SCM420/20CrMo4/20CrMo/4120
  • Tensile strength: 930+ N/mm2 (Mpa)
  • Hardness: Carburizing depth 0.6mm with HRC58~60
  • Thread part: Carburizing free on the thread part to prevent crack happening
  • Run out of T.I.R: 0.003mm

Why use steel SCM420/20CrMo4/20CrMo/4120?

  • The tensile strength is 930+ N/mm2 (Mpa)
  • SCM415/15CrMo5/15CrMo/4118 is only 830+ N/mm2 (Mpa)
  • SNCM220/21NiCrMo3/20CrNiMo/8620 is only 830+ N/mm2 (Mpa)
