反张夹头

内孔夹持，不用再伤脑筋

完整的加工常缺乏好的的内径夹持而告失败。很多状况下， 夹爪夹具是个临时替代的方案， 传统的沟槽式筒夹， 在精度、稳定性与膨胀行程也多有限制， 除非您使用的是H A I N B U C H 反张夹具系统。HAINBUCH反张夹具系统导入新的夹持技术，即使是在最困难的应用上，其表现仍然另人信服。HAINBUCH反张夹具的中心元件是经硫化处理过的夹固环。传统沟槽式筒夹系由弹簧钢制成，因此筒夹硬度限于此，其低硬度在夹持工件时，筒夹弯曲变形成为一种必然。而HAINBUCH夹固环，系由表面硬化处理过的镍铬合金钢制成，因此硬度极高、耐磨性与稳度性都很好。所有的接触表面皆一起研磨制造，以确保最理想的同心度。
优势：
夹固环上橡胶经硫化处理，具吸震效果。
轴向后拉力承靠着工件止动器，确保工件稳固夹持。
小径夹持也有大夹持力。
仅需八种反张模块尺寸，即可涵盖夹持范围8-100mm。
同心精度可能达到< 0.01mm。
硫化处理橡胶设计，夹固环膨胀范围大。
标准止动器，可自行加工至所需尺寸。
标准夹固环，可自行修整至想要的尺寸。
具备H A I N B U C H 夹具系列的特色： 平行夹持的功能
转换、坚固、高夹持力，以及耐磨耗。

EFFICIENT AND ECONOMICAL

Often complete machining fails for lack of an effective I.D. clamping device. In many cases the jaw chuck is a makeshift solution. However, even conventional mandrels with slotted clamping sleeves quickly reach their limits in terms of accuracy, rigidity, and opening stroke. HAINBUCH segmented mandrels use state-of-the-art clamping technology that is convincing, even in the most critical applications.
High holding power by HAINBUCH technology
The central element is the vulcanized segmented clamping bushing. Because conventional clamping bushings are made of spring steel and are only annealed to spring hardness, therefore they are soft and they must »bend« to clamp the workpiece. HAINBUCH segmented bushings, on the other hand, are made of case-hardened chromium-nickel-steel and have segments that are extremely hard, wear resistant and rigid. All contact surfaces are completely ground in one operation guaranteeing optimum concentricity.
Key advantages
●Vibration dampening due to vulcanized segmented clamping bushings
●Workpiece stabilization through axial draw force applied against the workpiece end-stop
●Extremely high clamping force even at the smallest clamping Ø
●Clamping range from Ø 8 – 120 mm with only 8 mandrel sizes
●All mandrels prepared for air sensing control
