          • EWS Varia VX

          • The new quick-change system for heavy cutting

            The race is won in the pit stop...

            The EWS-Varia VX quick-change system is now available across the complete range. The taper/planar support interface ensures maximum concentric accuracy.
            The torsional moment occurs with a positive polygon that transfers up to 200 Nm.

            Tightening and release takes place via a turn gear segment with 3 multifunctional cams. When a radially-attached tension screw is tightened, the 3-point tension pulls the tool insert evenly into position. When released, the insert is mechanically loosened via sliding cams and released from the holder for removal.

            For use in inner cooling, a diametrically-acting membrane seal ensures the leak-free coolant transfer between adapter and VX insert, thus bringing the medium directly to the cutter.

            With VX, the Innovation Prize-winning Varia system takes a step towards a new form of modularity, meeting the demands of future tool machining generations and the most modern machining technologies.

            Advantages:

            • cutting tools are in place and ready at the machine
            • quick change via just one clamping point
            • no risk of injury during tool changes
            • clamping of insets without any lateral forces
            • safe torque transmission
            • no loose parts
          • EWS CyberCon4

          • The digital view for capturing kinematic processes

            EWS develops its own sensor technology as part of the Industry 4.0 concept. With EWS. CyberCon4 enters the age of digital transformation. The digital concept is also open to competitors and cooperation partners in order to offer users as much standard as possible. The data can be read on a tablet or smartphone via an app. However, this is only part of the possibilities.

            Ews.CyberCon4 is a building block of the entire IoT concept of EWS. The electronics are currently in the field trial and optimization phase and were presented to the public for the first time at EMO 2017.

            Advantages

            • Avoid costly machine downtime thanks to intelligent tooling system
            • Detection of seal failure by "FCS (Fluid Control Sensor)" before machine damage occurs
            • Dynamic determination of load-dependent maintenance cycles
            • Sensor technology is open for communication with external interfaces
            • Data management, internal, external or cloud possible
            • Sensor based on BLE 4.2 technology (Bluetooth Low Energy)

            The sensors collect the following data:

            • Runtime
            • Speed
            • Temperature
            • Switching on and off
            • Sealing failure (water inlet)
            • Battery condition
            • Maintenance appointments
          • Keyway broaching with EWS Slot

          • Keyway broaching with EWS Slot

            Keyway broaching on lathes is a common thing. What is new is to speed up this operation with low stress for the machine!

            Slot is driven by the tool turret of the machine, with the input rotary motion being converted to a translation with superimposed lift-off function. This makes programming extremely easy. The keyway broaching unit is positioned in the prepared bore – in such a way as to make the extended tappet oriented to the end position in the Z axis. The depth of the slot is produced by a constant X-feed moving between 0.04-0.08 mm/stroke.

            The speed of the spindle ranges between 400 rpm – 1,200 rpm, with one rotation corresponding to a complete stroke.

            This way, for instance, a feather key groove with a width of 6 mm and a depth of 5 mm is produced within 7.5 sec. (800 rpm and 0.05 mm feed/rotation).

            With this operation it is important that the chip can break at the end of the groove, that is that a cut-in or a bore exists.

            It is not only slots or grooves, but also internal and external teeth that can be produced. This is particularly interesting for tools with partial teeth.

          • EWS-Multiform

          • 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 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.

            Function: 

            • The needed profile is created by using a cam disc. Both standard and customs versions are available.

            • The drive runs in the turret just like a driven tool.

            • Note: Constraint for turrets with permanently running driven tools as the rotation speed is limited to max. 1,000 RPMs.

          • EWS millLine

          • 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.

            Advantages

            • the smart solution for compensating for there not being a machining axis
            • Machining hard-to-reach parts
            • Centre boring
            • stepless angle adjustment around the horizontal axis, with tangentially acting double cone clamp MR > 250 Nm
          • EWS ProLine

          • 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.

            Cutting data similar to HSK63 machining centres?

            On a Gildemeister CTX Beta 1250 4A, two surfaces were milled at the same time in 16MnCr5 steel using two 80 mm-diameter cutter heads, with 3 mm feeding per head at a cutting speed of 180. One surface was produced without whistling or clattering; previously this could only be achieved with HSK63 machining centres.

            The two axial tools from the EWS ProLine were equipped with 4:1 planetary gear sets and featured the VDI40 shank holder.

          • EWS Swivel Head

          • Compact and stable – this is EWS' new swivel head.

            The swivelling module, which is equipped with a Cylkro drive system, is 17 mm smaller than standard heads which, above all, offers greater flexibility in swivel ranges between 0° and 45° in the field of cutting tools.

            The swivel unit covers an angle of +/- 92°. During the swivelling process, the supply of coolant is directly carried along. A distance of at least 48 mm from the contact surface to the swivel axis can be proposed. Even a high-pressure interior cooling system of up to 70 bar can be built into the module without the exterior dimensions having to be modified.

            Rotational speed limit is 6,000 1/min, maximum transmittable torque is 16 Nm, and max. cutting tool diameter is restricted to 10 mm.

            The swivel head is mainly suitable for drilling or for simple machining tasks. EWS' TWK range is available. for greater demands with regard to torque and performance. These are fixed angle tools which are specially produced for any angle range. The standard angles from 15° to 75° – graded in steps of 15° – are produced as standard by the Uhingen-based company and are generally available from stock.

          • EWS Gear Hobbing

          • 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.

          • EWS Swiss Tools

          • for STAR and CITIZEN machines.

            EWS quality now available for Swiss-type lathesThis new development in driven tools is EWS's response to many customers' requests. The tool systems may appear straightforward at first sight, but their simplicity belies their performance.

            The design concentrates on the mounting and the spindle concentricity. The requirement profile was developed jointly with an American medical technology company which uses very small drill bits and requires extreme concentricity properties. The spindle bearing technology used with labyrinth seals sets new standards in this field, and is associated with a long service life.

            Provision has already been made for service. The service centres in Germany, China, Korea and the USA have already been trained in the system and are ready to respond without delay. Third-party brands can also be serviced there at any time.

            Advantages

            • High precision bearings
            • Innovative sealing technology
            • Spindle concentricity < 3μ

            • Maintanance free
        • Static Tools

            • EWS Rigid

            • 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.

              EWS is presenting the new drilling rod system for the first time at the EMO 2013, equipped with an HSK63 base holder and an adapter for the EWS Capto C3.

            • EWS tcJet

            • The new EWS tcJet range

                • EWS Varia Quick Change System

                • 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
                  • Weldon/Whistle Notch
                  • Milling arbors
                  • Morse tapers
                  • Hydro extension
                  • Shrink adaptations

                  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. The holders are released from the machine by a mechanically impinged ejector system, so that agglutination by coolants will no long occur.

                  This solution reduces the risk of injury of the machine operator to nearly zero.

                  EWS-Varia is available for nearly all tool holders from VDI25 and BMT55, respectively.

                    • EWS Trifix®

                    • The Trifix® system

                      Trifix® is the new adjusting system for Gildemeister multi tasking machines. The double sided adjusting system is guided by a very precise key way at the surface of the turret.

                      The plates are preloaded, and the resiliency in the adjusting system eliminates static redundancy.

                      This allow the exact position of the tool to be secured and significantly reduces the setup time of the machine.

                      Because this is a highly sophisticated precision instrument it is not possible to use double serrated tool shafts.

                      The tool is supplied fully adjusted and can be used right away.

                      EWS is the DMG system partner for this tool generation.

                      Trifix® advantages:

                      • Repeat accuracy below 6 µm at radius of 200 mm
                      • High positioning accuracy from one station to another (0.01 mm)
                      • Driven tools and static tool holders are completely aligned
                      • Static tool holders can be used together with additional drill pattern for mounting
                      • Heavy duty spindle noses can be used together with additional drill pattern for mounting
                      • Tool disc / functional areas are easy to clean
                • Accessories

                    • EWS Zero-Zero

                    • Reaching concentricity 0 using a simple collet chuck and this within one minute: this is Zero-Zero.

                      The specifically designed clamping nut with 6 symmetrically arranged screws at the circumference makes this step possible. The clamping nut is split, so that the inner ring can be minimally shifted. This simple technical finesse allows to eliminate tolerance additions.

                      The machine operator only has to replace the previous clamping nut, which step opens up a new concentricity dimension – and this for a price starting at € 90.00. Zero-Zero is available for DIN 6499 collet chuck holders from ER 16-ER40.
