PALMARY - GU32X100NC

Features

• PALMARY's high precision cylindrical grinders are unmatched in structural rigidity, stability, grinding accuracy and operational convenience. Having maximum operational flexibility allows for various grinding operations.
• The spindle runs on precision bearings, assuring maximum spindle stability. It guarantees outstanding accuracy for external and internal diameter grinding and end face grinding.
• The grinding wheel spindle is precision machined from high quality alloy steel, it is then normalized, tempered, carburized, sub-zero treated and lastly precision ground and mirror-effect treated.
• Special hydrostatic bearings ideal for precision grinding work, allows for high speed with no friction between metals, no heat generation, deformation-free to maintain extra high accuracy for continual use.
• One grinder with various grinding applications such as straight plunge, shoulder, traverse, end face, taper grinding and internal grinding function (included option).
