Knuth 5.4HP HFS 40100 F Advance Surface Grinder 124930

Description

The HFS F Advanced series is the latest development of Knuth’s tried and tested surface grinding machines, which have proven themselves in many companies for decades. Although surface grinding is a widespread machining process, the machines in this series, with their extensive standard accessories, set a high standard as a turnkey solution. The advanced operating functions implemented with Siemens technology are new. These machines are the best choice for customers for whom conventional is too little and CNC is too much.

Features

• Magnetic table and built-in demagnetization feature
• Vertical axis with ball screw and servo motor for high precision
• Easy auto-mode programming with Siemens PLC and touchscreen
• Extensive standard equipment package
• The cast-iron machine frame features superior rigidity and torsional strength, precision guideways and excellent machining quality
• All guideways are lubricated reliably via a central lubrication system
• The workspace is protected by an easily accessible enclosure
• A powerful coolant pump is combined with a vacuum exhaust unit to clear grinding dust and aerosol during machining operations

Grinding spindle

• Large grinding spindle, dynamically balanced, completely sealed with permanent lubrication
• Preloaded precision-bearings ensure maximum grinding performance and high reliability over many production hours

Programming

• The high-quality preloaded ball screw and a powerful servo-motor ensure high precision and repeatability of positioning on the Y-axis
• The machine features an electronic hand-wheel for configuration tasks and manual movement of the grinding spindle
• If set to Auto mode, the user-defined roughing and finishing parameters, number of spark-out strokes, and return to zero are automatically processed

Hydraulics

• Superior quiet operation and low heat build-up ensure optimum work results in continuous operations
• Hydraulically operated linear table movement, infinitely variable, high consistency, and soft reversal of direction
• The external hydraulics unit with oil cooler ensures perfect temperature stability

Magnetic clamping plate

• Large magnetic chuck allows for torsion-free clamping and is included in standard equipment
• The control unit is integrated into the electric system to simplify operation, allowing quick clamping and degaussing for maximum production efficiency
