The comfortable solution
for profile and contour grinding

The BLOHM operator interface with graphical operator guidance for
the CNC control Siemens 840D with PCU 50 assists the operator in
combining parametric grinding and dressing cycles to a part program.
Process parameters can be easily adjusted which leads quickly to an

                                                                              CNC control
optimal grinding process.
Additional options are available to adapt programs even faster and
with greater flexibility.

BLOHM profile generates automatically grinding and dressing
programs with complex contours. The software simulates program
sequences as well.

The Software option single piece and batch production for the
Siemens 840D permits that programs are easily set up to meet individual
grinding tasks.

The main focus as it relates to dressings cycles is to support the operator
at the machine to CNC profile dress the wheel fast with great flexibility.

The grinding part of the software supports three different grinding
cycles, i.e. plunge, surface and creep feed grinding. Each cycle has
two individual input screens, one for the part geometry and one
for the grinding technology. The clear software structure makes it
very user friendly.

The specialties of the new software are related to many manual                Selection out of six pre-defined profile   Profile parameters

- Push button to start dressing on demand while the program is running
- Manual downfeed via handwheel to make part contact and continuing
   in automatic program mode
- Program interruption with automatic lift-off and continuation of the
   program are possible at any time (e.g. for measuring)
