Hainbuch offers small clamping solution for small workpieces

Hainbuch says that its latest jaw modules can be combined with its Spanntop or Toplus chucks to provide a lower weight, compact contour quick change clamping solution suitable for small and delicate workpieces up 200 mm. The modules provide ID clamping, OD clamping and jaw clamping.
Hainbuch points out that the unnecessarily large, heavy jaws found in many machine shops have a negative impact on productivity, machine durability and energy efficiency. The load they place on the machine spindle makes it slow to accelerate and decelerate.
Hainbuch argues that a lathe/milling machine with spindle taper DIN A2-6 65 mm bar capacity for, say, a workpiece range from 10 to 200 mm diameter, will usually be equipped with 215 jaw chuck, although 80% of the components will be in a clamping range of 100 mm and smaller. The user therefore suffers all the disadvantages of a large clamping device to process a small workpiece: it is difficult to get all of the tools in place; there is a higher risk of collision and tools will not reach centre line, so special longer reach tools have to be used leading to greater vibration and consequential loss of accuracy.
The jaw module is available in two sizes. The 144 model has a clamping range from 25 to 115 mm and the 215 model a clamping range of 25 to 200 mm. Mandrels and clamping heads can also be used in the basic unit. The system can be used as a pick-up chuck on sub-spindles.
