The innovative solution for complete machining of rotationally symmetrical and cubic parts, based on proven designs. The modular concept allows the machine to be produced with 1 or 2 independent spindles and with one or two cross slides. The PV³ combines technologies such as turning, drilling, thread cutting, milling, skiving, grooving or grinding and gear hobbing as well as hard turning and grinding including integrated quality check in a monitored process, all in one machine. Unique, patented tool carriers allow this high application flexibility in the part diameter range from 400 to 1,600 mm.

 

The uFlex is a compact, inclined hard-fine machining center with a compound slide in the upper area, which is fitted with a swiveling multifunction rotary turret or with static tools.

The multifunctional head can be equipped with various tools and measuring devices as needed.

The lower left area of the machine features a tool spindle. A manually adjustable tailstock is located opposite the tool spindle in the Z direction.

The machine can be loaded in various ways:

• Manual loading
• Robot cell
• DVS shaft automation
• Ovalband
• Highway connection

Highlights:

01
Combination of hard turning and grinding in one machine

02
High flexibility, perfect for single parts and small batches

03
Easy operation and programming through Ucee

05
Optional automation solutions: The DVS UGrind also works fully automatically with our ULoad or a custom solution, such as from rbc robotics.

If you want to accelerate progress, you need better brakes.

Progress in automotive development always pushes the limits of what is technically feasible. Increasingly, however, there are also additional requirements today, such as efficiency, sustainability and environmental compatibility, as demonstrated by the new Euro7 standard.

Combining the demands of top technical performance with those of environmental compatibility is a challenge in itself. To implement the whole thing efficiently and economically is clearly a case for DVS UGrind.

• Double-sided machining in the double surface grinding process
• extreme dimensional accuracy due to in-process measuring method
• fast loading and unloading by robot systems
• high workpiece throughput at low tool costs

In order to machine the latest generation of brake discs using the double surface grinding process, we have equipped a DVS UGrind with two opposing grinding spindles. We ensure dimensional accuracy by means of in-process measurement. In the machine, the position in the Z-direction and the thickness of the brake disc are determined before machining. On this basis, the brake disc is ground to size on both sides.

The DVS UGrind 800 is designed for workpieces with tip widths of up to 1,200 mm, while the DVS UGrind 1500 is recommended for larger ones of up to 1,800 mm. Both workshop machines for universal hard finishing feature the same advantages and reduce machining times by up to 80%.

• Efficient complete machining with grinding, turning and measuring tools on a single multifunction head
• Ideal for small to medium batch sizes of shafts and chuck parts with a center width of up to 1,800 mm
• Machine bed made of natural granite for high dynamic and thermal rigidity
• Consistently precise machining results thanks to hydrostatically mounted tailstock
• Faster to target dimensions thanks to intuitive DVS UCee operating system
• Only 7 or 8.5 m² floor space including coolant system
• Optionally with universal ULoad loading unit

Buderus Schleiftechnik GmbH has developed an innovative machine platform for the high-precision machining of rotationally symmetrical axes with a diameter of up to 300 mm and a length of 1,000 mm so that its customers can meet the requirements for maximum quality, low unit costs and maximum adaptability in equal measure.000 mm: the 235VH.

The machines enable both combined and simultaneous machining processes. The flexible configuration options allow a wide range of machining technologies from grinding, hard turning and honing to the use of driven tools. This means that the 235VH can also achieve the shortest possible routing and machining times.

Buderus is also the specialist in the use of center drive technology. Our latest development is the center drive machine 235VM with an advanced drive head. This new head achieves a working speed of up to 2,500 rpm and therefore also enables the hard turning of components. The innovative machine platform of the 235 VM is specially designed for machining rotationally symmetrical workpieces with a workpiece diameter of up to 80 mm and a length of up to 450 mm. The 235 VM enables both combined and simultaneous machining processes using a center drive.

The major advantage of center drive technology is the ability to machine internal and external geometries in just one clamping operation, which has a positive effect on both the precision of the machining process and significantly increases its efficiency.

Highlights:


01
The unique sustainable machine bed made of natural granite ensures high process stability thanks to maximum rigidity, vibration damping and optimum thermal properties.

02
Simultaneous machining with up to 4 cross slides in a single clamping operation drastically reduces set-up and cycle times with the highest shape and position tolerances.

03
Individual automation concepts offer simple, pragmatic through to highly complex solutions.

04
The large 22" ergonomic operation panel not only has excellent haptic properties. It can also be operated intuitively and configured individually without additional displays.

05
The Buderus multifunctional head and the NS axis, which can be swiveled continuously up to 225°, allow the individual and flexible integration of different technologies.

The PRÄWEMA SynchroFine® XL gear grinding machine is laid out for profile grinding on internal and external gears, on disc and shaft-shaped parts. The machine is laid out in three versions and is suitable for generating gears for components up to Module 32 with an outer diameter of 2,200 mm. Naturally the machine offers an option for hobbing gears up to Module 8.The natural granite machine bed is your guarantee for the highest geometric precision as well as static and dynamic rigidity. The low heat expansion coefficient and high thermal capacity ensures maximum thermal stability. All values for long-term precision, rigidity and thermal stability are better than those achieved e.g. with steel, cast iron or polymer concrete.The motion stand (X1 axis) for the grinding unit also consists of natural granite. The Z1 axis (grinding stroke in axial direction of workpiece) is designed as a wear-resistant linear drive. This allows high feed rates with excellent precision. The pivot axis (B axis) for adjusting the workpiece helix angle is laid out as a wear-free torque motor. The axis can be clamped hydraulically for rough grinding. The stable shift axis (Y axis) allows optimum grinding wheel dressing, correction movements during the grinding process up to incorporation into five-axis grinding for corrections, scanning measurement of the teeth up to use of the grinding operation with revolving worm. The grinding spindle used for hob grinding has an automatic balancing system and structure-borne sound sensors for sparking in.
