Our large WBM 221 twin-spindle surface grinding machine is a great success.

Ever since it was first developed, WENDT has delivered more than 300 units

worldwide. The continuously enhanced machine has two 500 mm grinding wheels.

While the lower wheel is fixed in axial direction, the upper wheel is lowered

to the required size. Four waisted-shank bolts pre-tension the three-section

cast iron base with great strength, thus providing excellent rigidity. The

grinding spindles have a hydrostatic bearing, which makes for excellent

damping behaviour. A hydraulic system that is completely integrated in the

machine base helps to achieve high thermal stability. The eccentric in-feed

system of the upper grinding spindle lowers the feed rate once the set size is

reached. With the automatically adjustable fixed stops, workpieces can be

positioned with very high precision.
WBM 221 applications
