HG - External grinding machine

Universal heavy-duty grinding with moving table
HG External grinding machine DANOBAT
HG External grinding machine DANOBAT

This horizontal cylindrical moving table grinding machine range has been designed to fulfil the requirements of a wide range of applications that combine external, internal, face and taper grinding of components such as transmission shafts, electric motor shafts, gas and wind turbine shafts, railway shafts, machine tools shafts, landing gear components, etc. Depending on the application corundum, CBN or diamond wheels can be used.

The machine base and sub-assemblies are made of stabilized pearlitic cast iron. HG grinding machines can be equipped with a wide range of wheelhead configurations: straight, angular and “B”-axis which is driven by an integrated torque motor. Wheels are assembled on hydrostatic bearing spindles, roller bearing or on DANOBAT designed electric-spindles.

In order to obtain the maximum machine performance, HG machines can be equipped with in-process measuring systems, automatic wheel balancing system incorporating gap and crash, axial positioning system and taper correction, etc.

Workpiece length: up to 5000 mm

Workpiece OD: up to 1040 mm

Grinding wheel diameter: up to 1060 mm
