R 4000-CNC MR
Available Models: R 4000-CNC MR/MD · R 5000-CNC MR/MD · R 6000-CNC MR/MD
- The R Series CNC MR and MD extend AMC-SCHOU's proven CNC cylindrical grinding platform to larger swing diameters — for manufacturers handling oversized rubber rollers, heavy steel rollers and large industrial workpieces.
- MR: approx. 900 mm swing — MD: approx. 1,200 mm swing
- Siemens 840D CNC — full surface contour programmability
- Same proven AMC-SCHOU platform scaled for larger workpieces
Overview
Extended Swing for Larger Roller and Industrial Workpiece Grinding
The R Series CNC MR and MD are AMC-SCHOU’s large-swing CNC cylindrical grinding machines — built for manufacturers who need the full programmability and precision of the standard R Series CNC platform, but require capacity for larger diameter workpieces. Both models are equipped with Siemens 840D CNC control and share the same travelling table design, hydrodynamic spindle, and European precision components as the standard R Series CNC, scaled to accommodate larger swing diameters.
Available Models
MR — approx. 900 mm swing: R 4000-CNC MR / R 5000-CNC MR / R 6000-CNC MR
MD — approx. 1,200 mm swing: R 4000-CNC MD / R 5000-CNC MD / R 6000-CNC MD

Performance
Precision and Flexibility at Larger Scale
Siemens 840D CNC Control Full programmability for all surface contours — cylindrical, parabolic, sine curves, crowns, convex, concave, radius, tapers, angles and multiple diameters. Siemens servomotors deliver variable speed, high accuracy, low vibration and large torque even at low speeds.
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 CNC.
Travelling Table Design Stable and accurate table movement ensuring consistent grinding results across the full workpiece length.
Hydrodynamic Grinding Wheel Spindle WEISS spindle ensures 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.
Optional Grooving System and X-2 Axis All optional equipment available on the standard R Series CNC is equally available on MR and MD models.
Simple, Low-Maintenance Design Very few movable components. Maintenance limited to cleaning and lubrication alone.
