The spindle ram and Z-axis are designed with 4-linear guideways (Roller type guideway, width 45mm) and a box-way construction. During heavy cutting vibrations are eliminated, and during fine cutting inert does not occur, resulting in higher surface accuracy.

SLG-1HS CNC High Precision Grinding Machine
1 grinding spindles, it could do one-surfaces grinding at the same time.

Machine Base
The X-axis linear guideways completed to support the table that maintains the highest precision at any position with zero overlay.
SIGMA CNC special design - Two columns distance from 2500mm to 3500mm that is equally supported with Three roller type linear guideways. Two columns distance 4000mm that is equally supported with Four roller type linear guideways. It’s for table’s positioning accuracy, loading balance and prevent heat deformation.

he spindle ram and Z-axis are designed with 4-linear guideways (Roller type guideway, width 45mm) and a box-way construction. During heavy cutting vibrations are eliminated, and during fine cutting inert does not occur, resulting in higher surface accuracy.
