Knuth NC controlled Surface Grinder HFS 31125 NC

High efficiency and unsurpassed precision combined with an intuitive control

Heavy machine frame in a rigid design ensures torsion-proof operation and optimum absorption of peak loads during table direction reversals
Large table offers space for workpiece sizes up to 1250 x 320 x 400 mm (LxWxH)
Preloaded ball screws on Y and Z axis ensure high precision during grinding operations
Machine features modern servo-drives, low vibration, and precise control
Automatic dressing reduces down-times and increases accuracy
Servo-drives allow dynamic feed adjustments and rpm control resulting in drastically improved surface quality
Automatic shut-down of electromagnetic clamping plate upon power outages
Machine setup can be accomplished via an electronic hand-wheel, which is directly coupled with the X- and Y-axis drives, reducing tooling time to a minimum
Work table feed speeds are variable and can be selected quickly
11 kW main motor provides ample power reserves for larger feeds
