WT external grinding machine DANOBAT

The medium and heavy duty WT grinding machine range has a cross slide coniguration to optimise the machine foot print. Machine main groups like wheelhead, workhead and tailstock are designed to grind components weighing up to 8 ton and 1000 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 conigurations: 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 equiped 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 1000 mm
