Overview

Extended Swing PLC Grinding for Larger Workpieces

The R Series PLC MR and MD extend AMC-SCHOU’s PLC-controlled grinding platform to manufacturers who require larger swing capacity for oversized rubber rollers, heavy steel rollers and large industrial workpieces. Sharing the same travelling table design, hydrodynamic spindle, and European precision components as the standard R Series PLC, the MR and MD models are scaled to accommodate larger swing diameters while maintaining the same straightforward operation and low-maintenance characteristics.

Available Models

MR — approx. 900 mm swing: R 4000-MR / R 5000-MR / R 6000-MR

MD — approx. 1,200 mm swing: R 4000-MD / R 5000-MD / R 6000-MD

Applications

Designed for Large-Diameter Roller and Industrial Workpiece Grinding

Typical Applications

• Large-diameter rubber roller grinding
• Heavy steel roller and industrial roller grinding
• Crowned and tapered roller grinding
• Large-format flexographic sleeve grinding
• Large industrial cylindrical workpiece grinding

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

Ideal For

• Rubber roller manufacturers handling large-format rollers
• Steel and industrial roller producers requiring larger swing
• Paper, textile and printing industry roller suppliers
• Workshops requiring larger capacity with straightforward PLC operation

Performance

Consistent Grinding Performance at Larger Scale

PLC Control Reliable control system for straightforward machine operation — easy for operators to learn and use in daily production, with simple maintenance requirements.

Larger Swing Capacity MR models offer approx. 900 mm swing over table; MD models offer approx. 1,200 mm swing over table — accommodating larger diameter workpieces beyond the standard R Series PLC.

Travelling Table Design Stable and accurate table movement ensuring consistent grinding results across the full workpiece length.

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

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

High-Quality Cast Iron Construction All main components cast from well-established foundries and specially processed to eliminate internal stresses — free of vibrations with long-term dimensional stability.

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