Accessories / Special features

A modern CNC control allows input of all relevant gearing data and dialog-assisted setup of the workpiece. Programming language switchable (German/English), and DNC interface for data import/export.
The machine operates in continuous generating grinding mode with automatic grinding cycles and in-machine automatic dressing of the grinding wheel.
Equipped with an automatic thread-in device for inserting the grinding wheel into the tooth gap – provides significant time savings, hydraulically swiveling.
About 10 years ago, BURRI retrofitted the profiling axis (V-axis) electronically, resulting in higher accuracy, simpler profile correction, faster dressing. Currently, a REISHAUER dressing unit Type SP-DR with a profile diamond disk is installed.
The workpiece swivel axis (A-axis) is also electronically controlled for fast, precise positioning and hydraulically clamped, allowing for quicker changeover and easier part loading.
Thanks to the shift grinding feature, the workpiece is tangentially guided along the grinding wheel during machining, ensuring a consistently uniform grinding wheel profile is in mesh.
DITTEL grinding wheel balancing unit
Hydraulic workpiece clamping with external collet and tailstock in the workpiece carriage
Complete working area enclosure with sliding doors and oil mist extraction
No original coolant system included (central supply), but a separate grinding oil centrifuge is available
Separate electrical and control cabinet, separate hydraulic unit in cabin, grinding wheel flanges
