Overview

Built for Precision Cylindrical Grinding Across Industries

The R Series CNC cylindrical grinding machine is AMC-SCHOU’s standard CNC solution for high-precision rubber roller and steel roller grinding. Programmed through the Siemens 840D controller, it handles everything from simple straight cylindrical grinding to complex surface contours including parabolic, sine curves, crowns, convex, concave, radius, tapers, angles and multiple diameters — all in a single setup. Available in four bed lengths to match your workpiece requirements, the R Series CNC combines rigid cast iron construction with European precision components for long-term stability and sustained accuracy in daily production.

Performance

Precision, Flexibility and Siemens CNC Reliability

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.

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 — resulting in machines free of vibrations and with long-term dimensional stability.

Optional Grooving System 4-programmable-motor grooving attachment operated through the Siemens 840SL controller. Programs for a wide range of groove profiles provided as standard. Milling up to 17,500 rpm; grinding up to 9,000 rpm.

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

Simple, Low-Maintenance Design Very few movable components resulting in minimal mechanical downtime. Maintenance limited to cleaning and lubrication alone.
