SK collet

ER

1.Made of specialmaterials, the chuck has advantages of corrosion resistance, large clampingforce, small deformation, stable precision and high wearing resistance; it canachieve about 1.5times of torque output of ordinary ER chuck. 2.High precision: Theradial run-out of Grade PP (instrument grade) is ≤0.001, which is far higherthan that of similar products in the market. 3.It has a smoothsurface and bright appearance, which make people feel comfortable when touchingit. 4. Scope of application:It is widely used for boring, milling, drilling, tapping, grinding, engravingand other machining areas. Generally, it is used together with the N.C. shank.It is suitable for a machining center with relatively high speed.
