WT external grinding machine DANOBAT

The medium and heavy duty WT grinding machine range has a cross slide configuration to optimise the machine footprint. Machine main groups like wheelhead, workhead and tailstock are designed to grind components weighing up to 15 ton and 10000 mm length. Gap bed option is available for large diameter swing components.

The machine base and sub-assemblies are made of stabilized perlitic cast iron. WT grinders 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. Depending on the application, corundum, CBN or diamond wheels can be utilised.

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

Workpiece length: up to 10000 mm

Workpiece OD: up to 1600 mm

Grinding wheel diameter: up to 1250 mm
