PALMARY high precision cylindrical grinders are unmatched in structural rigidity and stability, grinding accuracy and operational convenience. 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.


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.


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.


Various grinding application

One grinder allows straight plunge grinding, shoulder grinding, traverse grinding, end face grinding, taper grinding & internal grinding (optional) functions for different machining purpose.
