workpiecewith magnetic clampingconventional

Overview
The HFS F Advance series by KNUTH is a conventional surface grinder range combining a cast-iron machine frame with Siemens-based controls to deliver automated operating functions without full CNC complexity. Intended for workshops that require advanced conventional grinding capabilities.

Key features

• Magnetic clamping plate with integrated demagnetizing function
• Vertical axis with ballscrew and servo motor for precise positioning
• Siemens PLC with touchscreen and easy auto-mode programming
• Comprehensive standard equipment (magnetic chuck, automatic central lubrication, coolant and suction system, wheel dresser, balancing tools, LED lamp, operator manual)

Product details

• Machine frame: Cast-iron construction providing rigidity and torsional stiffness
• Lubrication: Central automatic lubrication for all guideways
• Workspace protection: Easily accessible enclosure to contain coolant and grinding debris
• Cooling and extraction: Powerful coolant pump combined with vacuum exhaust to remove grinding dust and aerosol
• Grinding spindle: Large, dynamically balanced, fully sealed spindle with permanent lubrication and preloaded precision bearings
• Programming: Preloaded ball screw and servo on Y-axis; electronic handwheel for manual setup; auto mode processes roughing/finishing parameters, spark-out strokes and return-to-zero
• Hydraulics: Hydraulically driven longitudinal table movement with soft reversal; external hydraulic unit with oil cooler for temperature stability
• Magnetic clamping plate: Large fine-pole magnetic chuck with integrated control for fast clamping and degaussing
