Our chucks are constructed with alloyed steel and they undergo a thermal processing of temper cementing and tempering that assures a strenght of 55-58 HRC.
The finish of the cone is performed by DIN 7178 regulation and it responds to the AT3 tolerance range. The assured concentricity between cone and the seat of tool is 5 micron for pincers holder chucks and 10-20 micron for other kinds according to the lenght and the diameter.
We can provide ISO 30 and 40 chucks balanced electronically to requested tolerance range, to satisfy needs that caused high speed in mechanical workings on tool machines.
Mereover, we can construct special chucks by request. To prevent misunderstandings, we advise you to use our code numbers at an order stage.
Balanced chucks take a differentiate processing course compared to the traditional chucks, because, after cementing and hardening processing, the are subjected to a double extension tratament in controlled atmosphere to obtain more stability in the chuck. Then, there is a cone griding with electronical control of the conicity, that allows AT3 tollerance achievement.
Having high precision, the balanced chuck assure a conectivity tollerance between cone, chucks and pincer holder seat less than 5 micron.
Chucks are balanced dinamically with electronical equalizer at 12.000 REV/MIN to G2,5 tolerance range, that admits imbalance readings (voiced in g/mm) very small to live for roating mass.
High precision and balancing consent more precision in processing and more life for the tool. For a best use of this kind of chuck, it is advised ER DIN 6499 extra-precise pincers utilization.
