Driven tools form a further core area of EWS. More than 8,000 different tools are available at short notice.
In addition to standard products like axial and angular heads, EWS offers swivel units, slot broaching tools, multiform tools and multi-spindle machines. There is just no limit.
The tool clamping systems range from the classic collet chuck holder to Weldon and hydro extension to Capto, KM, ABS and HSK.
The applications range from classic CNC lathes to highly complex turning milling centers.
The rapid change system EWS-Varia has set a standard for a flexible modular system. With its safe handling and short change-over times, EWS-Varia ranks among the most successful systems in the market. This was impressively confirmed by the Innovation Award awarded by the German state of Baden-Württemberg in 2006.
"Made in Germany" is of course guaranteed by EWS also for these tool systems.
Static tools form one of the EWS core areas. There is no other manufacturer in the world offering such a variety of products: More than 20,000 different tool holders are available for machine operators.
Our portfolio includes VDI tool holders with shaft diameters of 16-80 as well as block tool holders of BMT55-BMT85 to machine-specific holders for MAZAK, Okuma or Mori Seiki, to name just a few.
We also offer prism holders according to DIN 69881 (VDI3425 Bl.3) in all nominal sizes.
Our standard portfolio includes Capto, HSK, KM and ABS adaptations in addition to the standard holders.
Moreover, our scope of supply includes special holding fixtures made according to customer drawings or innovative solutions of the EWS engineers designed to master production engineering challenges.
The tool holders are manufactured at our factory in Uhingen and rightly carry the label:
Made in Germany!

The rapid change system EWS-Varia allows to set-up a modern CNC lathe or a turning milling center – and this flexibly.
A tool change will just take 20 seconds, which is an unbeatable argument especially in small batch productions whenever it is about reducing the set-up time and thus increasing the productivity.
The advantages, however, are also evident in large batch productions. Preset twin tools lie at the machine, thus significantly reducing the down-times.
A further advantage is provided by the variety of adaptations; so the optimal tool clamping can be selected for each operation. The inserts available include:
Collet chuck holders
The most important advantage is certainly created by the easy handling.
The inserts can be changed with just one hand without counter pressure by the spindle.

EWS goes milling
With its latest range of angular heads, EWS brings its trusted technology with new features to machining centres.
The system range was presented to the public for the first time at EMO 2015. An elegant design houses high-performance technology, or to put it simply
Precision meets Motion.
the smart solution for compensating for there not being a machining axis
Machining hard-to-reach parts
stepless angle adjustment around the horizontal axis, with tangentially acting double cone clamp MR > 250 Nm
The prerequisite is a "stop block" on the machine.
This prevents the entire unit from turning while simultaneously defining the position of the angel of rotation.

Gear hobbing on CNC lathes without B-axis
Years ago, EWS was the first tool manufacturer to offer gear hobbing heads in its standard range, and has continued to develop the holders for gearing technology ever since then.
With this technology, it became possible for the first time to produce external gearing on machines without a Y/B-axis. In contrast to a standard milling wheel holder, the tool head of the EWS modular cutter can be swivelled about the axis of the shank.
This offers users the advantage of substituting a B-axis with a comparatively small investment.
In the meantime, module 3 has become commonplace on VDI40/BMT65/BMT75 machines. The tool heads have become more stable at the same time as being more user-friendly.
The alignment system using a sinusoidal profile has come into widespread use and saves considerable alignment and setup times.

Make any centric or eccentric form desired
4, 6, or 8 edged, polygonal or free form with the EWS Multiform on the CNC turning/milling machines
Free forms that used to be impossible can now be made with EWS Multiform on turning/milling or machining centres.
For a six-edge outside the centre or a four-edge in the centre, additional processing steps such as reaming or eroding were necessary up until now. If a position change was also needed, complicated devices were needed for processing.
This is now all possible with one chuck.
What is behind this?
EWS Multiform uses a custom internal cam disc unit to produce the required form. For conventional geometry like squares or hexagons, there are standard cam discs available. The cam forces the cutting tool to follow a path in order to get the desired geometric shape. Of course you can’t defy the laws of physics which means that there will be a small radius on the edges.
The best of both worlds!
Insufficient stability was a fact increasingly associated with the VDI system in recent years. As a result, block tools were preferred more often, although the VDI tools still offer greater diversity and flexibility.
So the next step appeared obvious: combining the best of both systems. In cooperation with DMG, we developed the EWS ProLine system in order to fully utilize the potential of new lathes. While EWS ProLine features a conventional VDI shank, it can be optionally mounted to the turret using four screws.
For instance, the flexibility of the VDI system can be utilised for lighter machining, and the stability properties of block tools can be utilised for heavy cutting. The angular position of the radial tools is ensured through the Trifix®, the alignment system.

EWS.PSC offers maximum stability and rigidity coupled with maximum flexibility.
Significantly reduce your setup and changeover times while maintaining high mold flexibility.
he EWS.PSC program includes a wide range of standard tools with PSC shank for milling spindles as well as tool systems with PSC spindle for lathes. Furthermore, tool holders with plate seat are available.
The interface allows you to reduce the time spent measuring, setting up and changing tools.
In addition, improved machine utilization can be achieved.
EWS takes measures against vibrations in deep drilling procedures
Deep drilling procedures with drilling rods with a long overhang are one of the most demanding tasks in cutting technologies.
What influences vibration, what amplitudes does it create, what is the effect of superimposed vibration and when are uncontrollable resonances encountered? All these are questions that are difficult to answer using theory alone.
These findings formed the basis for the new development of EWS Rigid. The objective was to create a drilling holder with a passive damping system to counteract the vibrations that are created. This involves using variable vibration dampers with linear degrees of freedom in a floating mounting inside the cutter carrier.
The damper position is set using a radially mounted setscrew, which allows optimum vibration conditions to be created.
The improvement in surface qualities of bores is significant, as is the increase in the service life of cutter tools.
