ER collet

1.Made of specialmaterials, the chuck has advantages of corrosion resistance, large clampingforce, small deformation, stable precision and high wearing resistance; underthe same locking force condition, its wearing resistance is better than that ofSK chuck; therefore, it has a longer service life. 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 usedfor boring, milling, drilling, tapping, grinding, engraving and other machiningareas. Generally, it is used together with the N.C. shank. It is suitable for amachining center with the relatively high speed.
