EWS.Butterfly-Seal
  • The triad of front labyrinth, special sealing elastomer and preload ring forms the heart of this technology
  • The labyrinth technology protects against direct contact with cooling emulsion and dirt particles
  • The speed-related lift-off function of the sealing element reduces mold heating by up to 50 percent
  • Due to the contraction effect of the sealing elastomer, the sealing lip closes the path to the mold interior and ensures maximum safety against the suction of emulsion during the cooling phase 
  • No friction-induced running-in at the mold spindle (50 percent of all service cases)
  • In case of service: Inexpensive seal replacement instead of expensive spindle replacement

EWS.HPC-Line
The new HPC-Line (High pressure ceramic) from EWS sets new standards for driven tools with axial and radial rotary unions.

The time when you had to decide between using high speed in conjunction with low coolant pressure or high pressure at low speed is over. The newly developed EWS.HPC-Line sealing technology now represents a further quantum leap. The seal set, which is based on technical ceramics, is capable of covering 70 bar at up to 12,000 1/min. Added to this is unrestricted dry-running capability.

The running-in process in particular meant the technical knockout for many sealing systems after only a short time, because the previous seals burned out after only seconds or they hardened, which then led to failure within a very short time. The technical ceramic used in the HPC-Line has excellent dry-running properties, which was a key criterion in the developers' specifications.

Even in terms of heat generation, there is something positive to report, because the high-precision face seal causes far less heat than was the case with lip seals due to the optimized friction factor µ. In addition, the frictional force FR= µ x FN was reduced to a minimum through geometry optimization and intelligent load balancing at the sealing elements.

EWS.Polygon-Joint
For centuries, the keyway or spline connection was considered a set for the transmission of torque. The new possibilities in the field of manufacturing technologies, open up new dimensions for the developers of transmission units.

EWS relies on the polygonal shaft-hub connection in its new series and thus exploits significant technological advantages:

The balanced geometry reduces the imbalance of the driveline towards zero, a positive effect on the vibration of the work spindle and thus on the surface of the component. Added to this is the improved service life of the cutting edge and the increase in the service life of the entire tool system.

Due to the homogeneous force distribution over the entire circumference, up to 30 percent more power can be transmitted with the same dimensions, and the resistance of the connection to impact and breakage increases many times over.

EWS.swivel head
Adjustable up to +/- 115° with collet holder and support
The latest swivel head generation from EWS is equipped with a Cylkro gearbox, which brings great advantages in terms of stability and size. Thus, it is possible to reduce the overall length of the swivel heads by up to 17 mm compared to the standard mountings. This offers significantly more flexibility in the cutting tool length, especially in the swivel range of +/-45°, and also enables use on machines with very compact swivel spaces.

The swivel unit covers an angle of +/- 92°. During the swiveling process, the coolant supply is directly carried along. The distance from the contact surface to the swivel axis can be offered from 48 mm. Even a high-pressure internal cooling system up to 70 bar can be integrated into the module without changing the external dimensions.

The limiting speed is 6,000 rpm, the maximum transmittable torque is 16 Nm, the max. cutting tool diameter is limited to max. 10 mm.

The swivel head is mainly suitable for drilling or light milling applications. For higher demands on torque and power, EWS offers its TKW series. These are fixed-angle tools that are specially made for each angle range. The standard angles from 15° to 75° - stepped in 15° increments - are part of the Uhingen-based company's standard and are usually available from stock.

Module milling on CNC lathes without B axis
Years ago, EWS was the first tool manufacturer to offer module cutter heads in its standard program and has continuously developed the holders for the gear cutting technology. With this technology, it became possible for the first time to produce external gears on machines that do not have a Y- B-axis. In contrast to a standard disc cutter holder, the tool head of the EWS module cutter can be swiveled around the shank axis.

The advantage for the user is that a B-axis can be substituted with a comparatively small investment. In the meantime, even module 3 is common practice on VDI40/BMT65/BMT75 machines. The tool heads have become more stable and at the same time more user-friendly. The alignment system via sinus ruler has become established and saves enormous alignment and setup time.

EWS.Multiform
Create any desired shape centrically or eccentrically 4-, 6- or 8-edge, polygon or free-form shapes with EWS.Multiform on CNC turning/milling centers

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 multiple new possibilities however will allow engineers to come up with new processes for manufacturing. ID and OD slots, offset squares and straight polygons are examples of an endless list of opportunities. To see what shapes are possible all that needs to be done is verify with EWS application engineering.

EWS.ProLine
The best of both worlds!
Lack of stability, the VDI system has been increasingly associated with this fact in recent years, resulting in block tools being favored more and more, although VDI tools still offer greater variety and flexibility. So the next step seemed obvious, to combine the best of both systems, and in cooperation with DMG, the EWS.ProLine system was developed to take full advantage of the potential of new turning machines.

EWS.ProLine has a conventional VDI shank, but can optionally be fixed to the turret via four screws, allowing the flexibility of the VDI system to be used for light machining, and the stable block-tool properties for heavy machining. The angular position of the radial tools is ensured via the Trifix® alignment system.

Cutting data similar to HSK63 machining centres?
On a Gildemeister CTX Beta 1250 4A, two surfaces were milled in parallel with two cutter heads Ø 80 in 16MnCr5 steel. The infeed was 3 mm/head, at a 180 cutting speed. Without chattering or whistling, a surface was produced that was previously only known from HSK63 machining centers. The two axial tools from the EWS.ProLine were equipped with 4:1 planetary gears and had the VDI40 shank mount.

EWS takes a stand against vibrations in deep wells
Machining deep holes with long projecting boring bars is one of the most demanding tasks in machining technologies. What influences vibrations, what amplitudes do they generate, what is the effect of their superpositions, when do you encounter uncontrollable resonances? These are all questions that are difficult to address from theory.

This insight was the basis for the new development of EWS Rigid. The aim was to create a drill holder that counteracts vibrations by means of a passive damping system. Variable vibration dampers with linear degrees of freedom act on the dampers, which are mounted floating in the interior of the cutter carrier.

The position of the absorber is adjusted by means of a radially mounted adjusting screw, which can be used to create optimum vibration conditions. The improvement of the surface finish of bores, as well as the increase of the cutting edge life are significant.

Alignment system for Glidemeister turning-milling centers
EWS Trifix® is the alignment system for Gildemeister turning-milling centers. the alignment bars, which are mounted on both sides, each engage via a bevel in high-precision manufactured recesses in the turret surface. the bars are preset with preload. the spring effect of the alignment system eliminates static overdetermination. this ensures the twisted position of the tool holder without additional adjustment effort and thus significantly reduces machine set-up times. due to the high precision requirement, application for double-toothed tools is not possible. the tools are delivered pre-aligned and can be used directly.

EWS is a system partner of DMG MORI for this tool generation.

EWS Trifix® advantages
  • Repeatability on one station below 6 µm with 200 mm throat depth
  • high positioning accuracy from one station to another (0.01mm)
