內(nèi)孔夾持，不用再傷腦筋

完整的加工常缺乏好的的內(nèi)徑夾持而告失敗。很多狀況下， 夾爪夾具是個臨時替代的方案， 傳統(tǒng)的溝槽式筒夾， 在精度、穩(wěn)定性與膨脹行程也多有限制， 除非您使用的是H A I N B U C H 反張夾具系統(tǒng)。HAINBUCH反張夾具系統(tǒng)導(dǎo)入新的夾持技術(shù)，即使是在最困難的應(yīng)用上，其表現(xiàn)仍然另人信服。HAINBUCH反張夾具的中心元件是經(jīng)硫化處理過的夾固環(huán)。傳統(tǒng)溝槽式筒夾系由彈簧鋼制成，因此筒夾硬度限于此，其低硬度在夾持工件時，筒夾彎曲變形成為一種必然。而HAINBUCH夾固環(huán)，系由表面硬化處理過的鎳鉻合金鋼制成，因此硬度*、耐磨性與穩(wěn)度性都很好。所有的接觸表面皆一起研磨制造，以確保的同心度。
優(yōu)勢：
?夾固環(huán)上橡膠經(jīng)硫化處理，具吸震效果。
?軸向后拉力承靠著工件止動器，確保工件穩(wěn)固夾持。
?小徑夾持也有大夾持力。
?僅需八種反張模塊尺寸，即可涵蓋夾持范圍8-100mm。
?同心精度可能達(dá)到< 0.01mm。
?硫化處理橡膠設(shè)計，夾固環(huán)膨脹范圍大。
?標(biāo)準(zhǔn)止動器，可自行加工至所需尺寸。
?標(biāo)準(zhǔn)夾固環(huán)，可自行修整至想要的尺寸。
?具備H A I N B U C H 夾具系列的特色： 平行夾持的功能
?轉(zhuǎn)換、堅固、高夾持力，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 ?
●Clamping range from ? 8 – 120 mm with only 8 mandrel sizes
●All mandrels prepared for air sensing control
