RS CMX CB

The precision cylindrical grinding machine with a practical CB cycle control system, specifically designed for large components. All guideways are based on the proven, hand-scraped V-flat principle. With an extended center distance of 4,000 mm and a grinding wheel measuring 600 x 80 x 304.8 mm, this model processes spindles and shafts weighing up to 800 kg with absolute warpage-free precision down to the micrometer level.

    Hardware

    Robust Base Structure: The heavily ribbed, heavy-duty cast machine bed guarantees excellent static and dynamic rigidity as well as optimal vibration damping during continuous operation.

    Precision guideways: All linear guides are designed as V-shaped flat slideways. The ground and hand-scraped cast surface, combined with a TURCITE-B® coating, ensures maximum vibration damping and the highest surface finish during cylindrical machining.

    Ball screws (X/Z) & glass scales (X): The feed and longitudinal axes are equipped as standard with high-precision ball screws, and the X-axis features optical, linear glass scales for direct, high-precision position feedback (Z-axis optional).

    Manual Axis Extension (B-Axis): Flexibly expandable with a manually swiveling B-axis (spindle head for external, face, and internal grinding spindles) for precise and flexible adaptation to various grinding tasks.

    Automatic Central Lubrication: A fully automatic circulating lubrication system continuously supplies the guideways and moving elements of all axes with lubricating oil, ensuring low-maintenance operation.

    Safe Full-Enclosure: The standard enclosed cabin effectively contains emissions, ensures clean air in the workshop, and makes a significant contribution to maximum workplace safety during daily operation.

    Flexible satellite handwheel: During setup, all axes can be moved with extreme precision using a mobile handwheel (selectable increments: 1 µm, 10 µm, or 100 µm).

    Software

    Proprietary G+H software: The dialog-driven control system is based on a high-performance industrial PC. Entering all data is extremely straightforward and menu-driven via direct dialog—no knowledge of DIN code programming is required.

    Advanced cycle chaining: In fully automatic operation, up to 8 grinding operations per workpiece can be conveniently linked, managed, and copied. A detailed breakdown of all available processes can be found below in the technical specifications.

    Integrated workpiece and profile database: Ensures clear management and storage of process data for up to 50 workpieces, 10 grinding wheels, and 10 dressers. This guarantees minimal setup times for recurring jobs.

    Automatic Dressing & Compensation: Program-controlled dressing is performed directly from the workpiece headstock or tailstock, with the respective dressing amounts being compensated fully automatically by the control system.

    Constant Peripheral Speed (V-constant): The integrated control system continuously adjusts the spindle speed as the grinding wheel diameter decreases to guarantee a consistently uniform grinding pattern.
