Surface grinding machine HFS 60160 F NC

for large workpieceswith magnetic clampingNC

Description
This series of surface grinders machines large and heavy workpieces to tolerances required for precision surface grinding or for preparatory steps such as lapping or polishing. The machine uses a cross-bed design with a moving column to provide a long table guidance and optimal distribution of weight force. The unit can be operated automatically or manually, extending its use to sample production, repair and training.

• Moving-column (cross-bed) design for maximum stability
• Magnetic clamping plate with integrated demagnetizing function
• Siemens Smart Line PLC control with editable grinding cycles
• NC-controlled Y/Z axes driven by servo motors
• User-friendly HMI with touchscreen
• Electronic handwheel for Y/Z axes

Product details
Machine frame and general design

• Massive, heavily ribbed cross-bed frame with traversing column and horizontal spindle for high rigidity under heavy loads
• Large working area enables single large workpieces or several parts in one setup
• High-performance coolant system included as standard

Control

• Grinding cycles for automatic face and groove grinding accessible and editable via touchscreen
• Preloaded ball screws and powerful servomotors on Y and X ensure high precision and repeatability
• Electronic handwheel for Y and Z axes simplifies setup and manual positioning
• In Auto mode, user-defined roughing and finishing parameters, number of spark-out strokes and return-to-zero are processed automatically

Grinding spindle

• Large, dynamically balanced spindle, fully sealed with permanent lubrication
• Preloaded precision bearings for sustained performance and reliability

Hydraulics

• Quiet operation with minimal heat build-up for continuous use
• Hydraulic longitudinal table feed infinitely variable, maintaining constant speed and smooth direction reversals
• External hydraulic unit with oil cooler ensures temperature stability

Magnetic clamping plate

• Large magnetic chucks for torsion-free clamping across the work surface supplied as standard
• Modern control ensures reliable holding forces and high-quality demagnetizing
