machine description

CNC 235 H Hard machining center The CNC 235 H vertical hard machining center with horizontal workpiece spindle can be used for internal as well as external grinding. Moreover, these processes can be combined with one another as well as supplemented with other technologies such as hard turning or hard reaming. In addition to sequential machining, the machine can also be equipped for simultaneous machining, i.e. external and internal grinding at the same time or several simultaneous external grinding operations.

machine description

 

CNC 235 M Hard machining center The CNC 235 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.

machine description

<b/>

CNC 28 M, the two sided machine The CNC 28 M double sided, internal, external and surface grinding machine guarantees very short machining times and maintenance of high shape and position tolerances because up to 4 grinding wheels machine the workpiece simultaneously. This is made possible by the center drive with high precision hydrodynamic or hydrostatic workpiece spindle. The machine can process a wide spectrum of workpieces. This includes, among others, two sided machining of housings, drive shafts, hydraulic parts and many others.

CNC 635 A LP

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.
