Chuck SPANNTOP Mini

Pull-back

Deadlength

The new »mini« series really shines with a mass reduction of 38 %, 1/3 of less total length and 1/3 of lower chuck diameter. this means reduced energy consumption and better tool accessibility.

Thanks to the reduced interference contour, it is easier to choose the suitable tool. Now it can also be shorter and more stable – on the main and sub spindles. Particularly in the case of limited installation space and in series operation, SPANNTOP mini is ideal: Lower energy consumption, dynamic spindle acceleration and shorter cycle times lower the costs per workpiece.

Naturally the small SPANNTOP variant offers the same concentricity and low-wear characteristics as its big brother.

Minimalism that pays off!

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
