Peripheral grinding machine series RFT

The CNC-controlled peripheral grinding machine is designed for grinding surfaces, cutting edges and contours on circular knives, saw blades or circular blanks. It works in a pendulum or plunge-cut process and is equipped with six axes. The grinding wheel is moved horizontally via an AC servomotor with a preloaded ball screw. In conjunction with an additional grinding axis, subsequent grindings can be carried out in one clamping operation. The workpiece is held by a mechanical clamping device via a permanent magnet or electromagnet. With the Marposs measuring system, it is possible to machine an interrupted grind.

• Horizontal grinding wheel, positioning by AC servo motor driven by pre-loaded precision ball screw
• Automatic compensation of workpiece plunge travel after each dressing cycle and maintenance of selected rotational wheel speed (by frequency variation)
• Simple workpiece oriented programming with parameter entries
• Grinding of multiple bevels on one clamping with additional grinding axis
• Blade diameter of up to 1,200 mm
• Circular knife blade held on a rotational fixture by permanent magnet, magnetic chuck, or mechanical clamping
• Rotational speed of workpiece adjustable with frequency converter or servomotor
• Different dressing systems, interval controlled or permanent
• Processing of intermittent grinding by means of the measuring system Marposs
