An energy-efficient compact device has re-defined jaw clamping and marked the beginning of a new era in workholding. Hainbuch has introduced a jaw module that is small, flexible, can be quickly changed, and covers a large clamping range. And together with the Spanntop chuck, they become a quick change clamping solution for all situations.
Mandrels and clamping heads can also be used in the basic unit. The new jaw module completes the circle and gives a new clamping dimension that opens up even more possibilities for users. All this with less weight and a smaller interference contour.
Small, But Still Powerful
The Hainbuch solution, consisting of a chuck and a jaw module, has nothing in common with the large, heavy, energy sapping big jaws that can be found in many machine shops; where their size is more of an obstacle than an advantage. These heavy chucks put load on the machine spindle and are slow to accelerate and decelerate losing time and using energy. This takes longer for the part to be produced and hence makes it more expensive and also wears the machine bearings out quicker.
Lets assume that someone purchases a lathe/milling machine with spindle taper DIN A2-6 65mm bar capacity, here the workpiece range is usually diameter of 10 to 200 mm. To cover that range a machine with a 215 jaw chuck is purchased. However 80% of the components are in a clamping range of 100 mm and smaller. And here the dilemma arises that in practice you have to cope with daily -- large clamping device, small workpiece. It is difficult to get all of the tools in place. Often the tools will not reach center line and special tools are required with longer reach increasing vibration and losing accuracy. Also, there is a high risk of collision.
Simple Formula: Small Workpiece = Small Clamping Solution
Using the new small jaw module, about 80% of usual components are covered. For larger components it can be easily changed over to a large jaw module within 30 seconds. The basic unit is a Spanntop chuck or Toplus chuck, excellent workholding devices in their own right. So add to this the jaw module, clamping heads and mandrels and you achieve reliability, accuracy, and safety that traditional jaw chucks lack, especially for I.D. clamping.
