DVS Technology Group

Hall 4, Stall # C117

The DVS Technology Group and its companies Buderus Schleiftechnik, Diskus Werke Schleiftechnik, Pittler T&S, Präwema Antriebstechnik, Werkzeugmaschinenbau Ziegenhain and Naxos-Diskus Schleifmittelwerke as well as DVS Tooling will be exhibiting at IMTEX.

One highlight at the booth in Hall 4 Stall C117 will be the new machine concept DVS UGrind — an innovative workshop machine for the efficient and flexible hard finishing of small batches. Thanks to the multifunctional tool revolver for grinding, turning and measuring operations — as well as the intuitive operating software with integrated processing and measuring cycles and automatic calculation of the most efficient process strategy — machining time for the manufacturing of shafts and chucking components can be reduced by up to 50%.

The DVS UGrind is an innovative workshop machine for the efficient and flexible hard finishing of small batches.

Depending on the configuration required by the user, the DVS UGrind carries out external and internal, face and cone surface grinding as well as hard turning operations with minimum travel. The integrated measuring probe controls and monitors machining until the required final dimension has been achieved, which means time-consuming processes such as successive feeding and re-measuring are no longer required. Optimised lever arm ratios and the thermo-symmetrical structure of the DVS UGrind guarantee a high degree of dynamic and thermal machine stability and thus ensure constant reproducibility of the required manufacturing qualities.

Präwema Antriebstechnik: "Vario Cross Honing" for extremely precise gearing surfaces
Präwema Antriebstechnik GmbH from Eschwege in northern Hesse, Germany, is a global market and technology leader in the gearing honing segment. Präwema will present its latest innovation in the top technology field for optimising gearing surfaces — the so-called "Vario Cross Honing" technology. By using a specially developed oscillation method during the honing process, Vario Cross Honing enables surface roughness to be reduced even further, resulting in another increase in the surface quality of geared components. This innovation, yet another benchmark in gearing machining from Präwema, allows gearing manufacturers to produce wear- and noise-reduced vehicle gearboxes with higher torque transmission.

Präwema's Vario Cross Honing produces extremely precise gearing surfaces.

Pittler PV315: Gear cutting using the highly productive Power Skiving method

Pittler T&S GmbH, based in Dietzenbach in southern Hesse, will be presenting the PV315, which is the very latest addition to the PV3 family of machines for Power Skiving as well as complete machining and has been specially adapted to the requirements of commercial vehicle components such as gearbox components like ring gears. Equipped with a multi-function head, Y-axis and tool magazine for up to 20 different machining tools, the PV315 turns, drills, grinds, mills and deburrs as well as machining internal and external gearing of the quality class IT6 using the highly efficient power skiving method. This results in a surface quality with an Rz value of less than 2 μm on the tooth flanks as well as a main time three times lower than if the shaping method were used. At the same time, tool costs are reduced since the versatile tool magazine of the Pittler PV315 provides a skiving tool for rough skiving first followed by a finishing skiving tool, thus significantly extending the service life of the higher quality finishing tool.

Pittler's PV315 Power Skiving machine is adapted for production of commercial vehicle components.

Precision Measuring Center P 40: As Easy to Use as 1–2–3, Thanks to Its Intuitive User Interface
The fully automatic CNC-controlled precision measuring center is designed as a compact unit for the workpiece diameter range up to 400 mm. At the heart of the P 40 is an accurate, durable rotary table. Configured as a measuring axis (C axis), it provides concentric seating of the workpieces to be tested.

All precision measuring centers are now equipped with new versions of the calibration software and an advanced graphical user interface. The new Windows user interface — established on the market under the “EasyStart” brand — now allows the machine operator to operate the machine in a manner that is both significantly easier and target-oriented. A clearly structured user interface, featuring a tiled layout and a distinct set of symbols for each measuring application, ensures a quick and easy program start on the gear measuring machine. Most machine operators will already be familiar with this type of application from the current general Windows system interface.

The Klingelnberg P40 is designed as a compact unit for the workpiece diameter range up to 400 mm.

Bevel Gear Cutting Machine C 30: Leading-edge Technology for Optimal Flexibility and Maximum Productivity
In cars, spiral bevel gears are used in all-wheel-drive systems and rear-wheel-drive systems to transmit torque "from the transmission to the road." Due to increasing performance requirements, these drives must transmit outputs of over 300 kW in some cases. The bevel gears they use must be efficient, smooth-running, and low-maintenance.

Thanks to ongoing advancement of the vertical concept, the Oerlikon C 30 bevel gear cutting machine sets new standards in dry processing. All machines in this series are equipped with a thermostable, vibration-damping machine bed. An optimized axis arrangement also ensures reduced approach paths and thus significantly less load on the drive components — and a more rigid design of the overall system. Moreover, an integrated deburring tool enables maximum productivity and utmost process safety through the use of the PULSAR method.

According to the manufacturer, the Oerlikon C 30 bevel gear cutting machine sets new standards in dry processing.

Cutting Head Setting and Checking Device CS 200
The qualitiy of the gear cutting tools used is of major importance when producing spiral bevel gears. With dry-cutting in particular, a consistent cutter life and high quality can only be achieved if the cutter heads are precisely adjusted. The Oerlikon cutter head setting and checking device CS 200 enables quick and easy setup of these cutter heads, as well as allowing the position of the individual blades to be checked and documented.
