machine description

 

 

 

 

The BV hard machining center was developed for complete final processing of large parts. The modular machine design allows realization of all technologies required for final machining such as internal, external, surface and conical grinding, turning, drilling, reaming and milling.  This makes it possible to finish parts with diameters up to 5,000 mm. Workpieces can weigh up to 40 t, depending on the size of the workpiece spindle

Modular BV machine design Our philosophy of complete processing with one single clamping operation, along with consistent orientation to customer requirements, has led to compact machines with modular design offering maximum flexibility. These machines are used everywhere complex machining processes with minimum cycle times are required and minimum shape and position tolerances are necessary. Optionally the machines can be equipped with one or two compound slide rests. In addition to complete finishing, equipping with a number of compound slide rests allows simultaneous machining. For example internal and external cylinder grinding operations can be performed simultaneously in this manner, significantly reducing the machining time without decreasing the quality. With machining diameters up to 1600 mm it is possible to equip the machine with two workpiece spindles. This makes it possible to decouple the charging and discharging times from the actual machining time.

machine description

 

CNC 245 Hard machining center The CNC 245 vertical hard machining center with vertical workpiece spindle can be used as a single purpose machine for

  • Internal grinding
  • External grinding
  • Hard turning

Moreover, these processes can be combined with one another as well as supplemented with other technologies. In addition to sequential machining, the machine can also be equipped for simultaneous machining, i.e. external and internal grinding at the same time. Use of a consistent module design also allows the possibility of equipping the machine with two main spindles, i.e. two workpieces can be machined simultaneously or the front and back can be machined at the same time.

building set

The module system starts with the machine bed.
Sizes are available starting at 1,920 mm in increments of 450 mm.
This results in small compact machines with only one machining station right up to simultaneous machines with two main spindles,
which are then larger, but nevertheless still compact
in consideration of the possibilities offered.

Naturally, in addition to welded designs, Buderus also offers the machine bed in natural granite. We offer standard machining and handling modules for

Internal grinding

Additional data

Simultaneous grinding with CNC 245
Buderus has specialized in simultaneous grinding for more than 20 years. On the CNC 245, it is possible to use one additional X axis and one additional Z axis to simultaneously perform external and internal grinding operations.
This shortens the main time by the machining time for the shortest grinding operation.

 

CNC 245 DH with two main spindles
One control, one conveyor belt, one machine bed, one chip conveyor and one housing suffice for two main spindles. So why not integrate two machines in one? This allows twice as many parts to be produced in the same time or makes two-sided machining possible.

machine description

The CNC 245 M is a vertical grinding machine with center drive allowing machining of parts from two sides. This makes it possible to machine the inner and outer diameter, as well as enabling surface grinding on a workpiece sequentially or simultaneously in one clamping operation. This achieves high concentricity of the ground diameter and surfaces in relation to one another while reducing cycle times. Various hydrostatic bearings are available for the center drive.

machine description

CNC 635 external grinding center The CNC 635 external grinding center is available in two size versions. One version is designed for workpieces with a grinding length of up to 500 mm and the other for workpieces with grinding lengths up to 1000 mm. The machine is suitable for straight plunge cut and angular plunge cut grinding as well as for rough and thread grinding. It can be equipped with one, two or even three grinding supports, so that it is usually no longer necessary to reclamp on other cylindrical surface grinders.

machine description

CNC 635 G Male thread grinding machine In addition to metric, Whitworth, trapezoidal threads and special profiles, the CNC 635 G also allows grinding of worm gears with shapes ZK, ZN, ZE and ZA with one or multiple starts. The cylinder correction can be programmed with the control. The pitch can also be programmed variably over the thread length. The machine can be supplemented with a female thread grinding unit with high frequency grinding spindle. The tools are profiled by means of plunge cut dressing on a profile roller or path control via the machine axes on a universal diamond roller.
