Overview

Heavy-Duty CNC Cylindrical Grinding for Large and Heavy Workpieces

The R Series Heavy Duty CNC is AMC-SCHOU’s largest capacity cylindrical grinding platform — designed for manufacturers who require full Siemens 840D CNC programmability combined with the structural capacity to handle extremely large and heavy workpieces. With 1,100 mm swing over table and workpiece capacity up to 15,000 kg, the HD series handles demanding rubber roller, steel roller and industrial workpiece grinding requirements. Available in three bed lengths up to 6,000 mm grinding length.

Available Models R 2000-CNC HD / R 4000-CNC HD / R 6000-CNC HD Swing over table: 1,100 mm Max. workpiece weight: 15,000 kg / 33,000 lbs

Applications

• Heavy steel roller and industrial roller grinding
• Complex surface contour grinding — parabolic, crowned, convex, concave, taper
• Heavy-duty grooved roller grinding (with optional grooving system)
• Large-format flexographic and printing roller grinding
• Heavy industrial cylindrical workpiece grinding up to 15,000 kg

Roller Materials Supported Rubber, silicone, polyester, urethane, nylon, photopolymer sleeves, fiberglass sleeves, polyurethane sleeves

Ideal For

• Large-format rubber roller manufacturers
• Steel mill and heavy industrial roller producers
• Paper, board and textile industry large roller suppliers
• Manufacturers requiring the widest possible swing and workpiece weight capacity

Performance

Maximum Capacity with Full CNC Precision

Siemens 840D CNC Control Full programmability for all surface contours — cylindrical, parabolic, sine curves, crowns, convex, concave, radius, tapers, angles and multiple diameters. Siemens Simodrive motors power both the headstock and grinding wheel spindle.

1,100 mm Swing Over Table The largest swing in the AMC-SCHOU R Series — accommodating workpiece diameters significantly beyond the standard and MR/MD models.

Up to 15,000 kg Workpiece Capacity Maximum workpiece weight between chucks: 15,000 kg / 33,000 lbs.

Up to 6,000 mm Grinding Length Three bed lengths available — R 2000-CNC HD (2,000 mm), R 4000-CNC HD (4,000 mm), R 6000-CNC HD (6,000 mm).

WEISS Hydrodynamic Grinding Wheel Spindle Vibration-free rotation with runout less than 0.001 mm — the spindle rotates on an oiled film for smooth, consistent stock removal even on heavy workpieces.

Heavy-Duty SKF Bearings SKF bearings in heavy-duty design in head- and tailstock ensuring smooth and trouble-free rotation of extra heavy workpieces.

SKF & Deutsche Star Rexroth Ball Screws High-precision ball screws for X- and Z-axis ensuring smooth, accurate and trouble-free movements of the antifriction covered table and wheel slide.

Heavy-Duty Cast Iron Construction All main components cast from well-established foundries and specially stress-relieved — delivering long-term stability and sustained precision under heavy production demands.

Optional Grooving System 4-programmable-motor grooving attachment for a wide range of groove profiles — milling up to 17,500 rpm; grinding up to 9,000 rpm.

Optional X-2 Axis Additional rear-of-bed axis for a second grinding wheel for rough grinding or polishing unit installation — integrated with CNC controls.

Simple, Low-Maintenance Design Very few movable components. Maintenance limited to cleaning and lubrication alone.
