Double Column NC Series

This series is designed for productions which demands speed, accuracy, rigidity and very large grinding area. These machines are perfect for grinding medium to large size parts for aircraft, wind turbine, automotive, power generation, oil exploration, mining and heavy machinery.
The machine base features hardened and ground double “V” longitudinal slideways for optimum straightness and smooth table movement.

LOW-FRICTION COATED SURFACE

LOW-FRICTION COATED SURFACE

Most of the slideways consist of one cast iron precision scrapped surface in contact with a specially designed anti-friction coated surface. The combination of these two precision flat surfaces in contact with each other minimizes the friction dramatically lowering stick/slip. Smooth fluid motion and high wear resistance are added benefits.

PERFECT SCRAPED SURFACE

PERFECT SCRAPED SURFACE

The surface of longitudinal table ways and saddle ways are all hand scraped by experts to get the perfect contact pattern between the machining surface and to ensure high accuracy.

GUARANTEED STABILITY

GUARANTEED STABILITY

A specially designed hydraulic system results in extra smooth table movement, prevent excessive heating of hydraulic oil, and reduces table reversal shock. Coins can be kept on saddle standing balanced on edge during grinding operations attesting to the outstanding smooth operation of PROTH Grinders.

CASTING COMPONENTS

CASTING COMPONENTS

Massive one piece casting design provide a rock solid platform for years of accurate performance. All the main machine casting components, such as base, table, saddle, column, etc., are all annealed twice with particular attention to removing all metallurgical stress.

GRINDING SPINDLE

GRINDING SPINDLE

The precision high rigidity spindle is of cartridge type design. This provide for easier accessibility and service when maintenance is needed. Multiple hi-precision anti-friction axial and radial bearings are utilized specifically designed for absolute minimal play and run-out. Spindles are quiet and vibration free.

LONGITUDINAL TABLE WAYS

LONGITUDINAL TABLE WAYS

The sliding ways of the table are designed to be much longer than the actual working surface of the table top. This keeps the table free from torsion and deflection.
