Fixed headstock turning

Fixed headstock turning

Our machine park consists of a total of twelve machines. Each of these machines has its own function. Read more about how we use our machines here.

About

For Fixed headstock turning, we have 4- and 6-axis TNE and TNC Lathes from Benzinger at our disposal. They are characterized by their high accuracy in large numbers of short workpieces. In addition to the tireless turning of rings with a thickness below 1mm, with powered tools they can provide products with slots, holes, threads, or other add-ons They can be characterized as workhorses with velvet gloves. We use the following machines for short turning:

  • Benzinger TNE

All products are checked in our measuring room. Usually this check takes place on 100% of the products, but depending on the necessity and the production step, this can also be done randomly. The checks take place both visually under a Zeiss microscope and physically using a measuring set-up The measuring room is equipped with a state-of-the-art multisensor measuring set-up by Hexagon, which can measure tactile and optical by means of multiple techniques.All measured data is stored per product, per batch, and per production machine. a very large statistical source of information, which works with a high degree of accuracy. For measuring purposes we use the following machine:

  • Hexagon 443 Dual Z

About

Moving headstock turning is a technique developed in Switzerland for fine mechanics, with which products with the smallest diameters can be turned as accurately as possible and in large numbers. With this technique, the chisel does not move, but the material itself moves through the spindle. The advantage of this method is that the chisel always cuts as close to the spindle as possible. As a result, the material bends least under the chisel pressure. Within Exakt we use the long lathes Tornos Nano and Micro. These machines are characterized by their extremely high accuracy and tool life. The longer they run in succession, the flatter the tolerances. In short: gems of machines.

About

Wire EDM is a method of machining where the material is not subjected to mechanical stress. The part to be machined is placed in a liquid dielectric in the machine. The workpiece takes the role of an electrode, and the dielectric also contains a very precisely tensioned wire that forms the other electrode. An electric current is carried between the electrodes. The short circuit creates sparks on the surfaces of the electrodes, which are immediately dissipated as microscopic chips by the dielectric. Our Agie Charmilles CUT 200SP wire EDM machine is characterized by a backlash-free wire guide and extremely high surface accuracy on the cutting edges.

After processing, but also between different operations, workpieces must be aftertreated. Exakt has a special department for this with various finishing arrangements. In addition to different baths, ultrasonic and vapor methods, there are special drum arrangements. There is a drying drum installation with different drums, in which the products are tumbled for deburring and polishing. Using a whirlpool with grinding stones and water, two special drums can grind and degrease the workpieces very accurately. For post-treatment we use the following machines:

  • Dreher VT-5
  • Avatec TE 18N
  • OTEC CF1X18
