External cylindrical grinding machine M14 series

workpieceuniversalconventional

Overview
Structure: Left and right guide rails use a P-V structure, hand-scraped with high precision to ensure accuracy and stability. Front and rear feed guide rails of the grinding wheel are available in roller or wire-rail configurations. The control mechanism is classic, simple, safe and reliable. Models in the M1350, M1450 and M1363 series feature high-stability hydrostatic guide rails and high-rigidity dynamic/static pressure spindles. The universal workhead is adjustable up to +90° counterclockwise for chuck grinding of internal and external conical workpieces.

Features / Highlights

• P-V structure guide rails hand-scraped for high precision and stability.
• Front/rear grinding wheel feed rails available in roller or wire-rail configurations to suit application needs.
• Proven, simple control mechanism for reliable operation in production environments.
• Selected models (M1350/M1450/M1363) equipped with hydrostatic guide rails and high-rigidity dynamic/static pressure spindles for enhanced performance.
• Universal workhead adjustable to +90° (counterclockwise) for internal and external conical chuck grinding.

Applications & Buying considerations

• Suitable for external cylindrical and internal grinding of shafts, cones and precision cylindrical parts across small to very large workpieces.
• Choose model according to max O.D. length, center height and workpiece weight capacity required (M1420–M1463 range covers light to heavy-duty applications).
• Select roller or wire-rail feed guide configuration based on required stiffness and maintenance preferences.
• For highest static/dynamic accuracy and heavy-duty spindle work, consider variants with hydrostatic guide rails and dynamic/static pressure spindles.
• Provide workpiece dimensions, weight and required grinding tolerances to obtain the optimal model and wheel configuration.
