Each machine provides maximum operational flexibility thereby allowing for various grinding operations. You will get extra value when putting a PALMARY cylindrical grinder on your production line.

 
FEATURES
work-spindlejpg

Stable and rigid spindle head

The spindle runs on precision bearings, assuring maximum spindle stability. It guarantees outstanding grinding accuracy for external dia., internal dia. (optional) & end face.

wheel-spindlejpg

Special hydrostatic bearing

The wheel spindle runs by using a special hydrostatic bearing and is especially ideal for precision grinding work. It features high speed, no friction between metals, no heat generation, deformation-free, extra high accuracy and continual use.

Precision wheel head

Precision wheel head

The grinding wheel spindle is precision machined from high quality alloy steel, normalized, tempered, carburized and sub-zero treated, precision ground and mirror-effect treated.
