Accessories / Special Features:

A modern CNC controller enables the input of all relevant gear parameters and workpiece setup in dialog with the control system. Programming language (German/English) selectable, and DNC interface for data import/export.
The machine operates using a continuous generating grinding process with automatic grinding cycles and in-machine automatic dressing of the grinding wheel.
Equipped with an integrated automatic device for threading the grinding wheel into the gear gap, resulting in significant time savings; device is hydraulically pivotable.
About 10 years ago, the profiling axis (V-axis) was retrofitted electronically by BURRI, providing higher accuracy, easier profile correction, faster dressing; currently fitted with a REISHAUER dressing device type SP-DR with a profile diamond disk.
The workpiece swivel angle (A-axis) is also actuated electronically, quickly and precisely, and hydraulically clamped; this allows for faster setups and simplified workpiece loading.
The shift grinding device guides the workpiece tangentially past the grinding wheel during grinding, ensuring a consistently uniform engagement of the grinding wheel profile.
DITTEL grinding wheel balancing system
Hydraulic workpiece clamping with external chuck and tailstock in the workpiece slide
Complete working enclosure with sliding doors and oil mist extraction
No original coolant system present (central supply); however, a separate grinding oil centrifuge is available
Separate electrical and control cabinet, standalone hydraulic unit in cabinet, grinding wheel flanges
