The High Precision CNC Vertical Grinders include the YHJMKG×2 Series and YHJ2M Series, both designed for high-precision and high-quality surface machining. The YHJMKG×2 Series is ideal for industries such as equipment, bearings, aerospace, and energy, targeting the machining of inner holes, outer diameters, grooves, tapers, and end faces of disc, ring, and sleeve-shaped parts. It achieves machining accuracy of IT3~IT2 and surface roughness ≤ Ra0.2. Equipped with left and right double grinding heads, it supports simultaneous operation through dual-channel functionality to enhance efficiency. Its CNC system handles wheel dressing, enabling precise grinding. Optional features like in-process measurement, dynamic balancing, an AE anti-collision system, and an automatic wheel magazine improve machining safety and quality. The YHJ2M Series specializes in grinding precision discs, rings, and bushings. It achieves comprehensive grinding of bores, outer diameters, end faces, tapers, and grooves in one clamping. Its CNC linkage ensures form dressing and grinding, supporting external, internal, and taper grinding through dual-channel functionality. Both series offer exceptional precision, versatility, and efficiency, catering to demanding machining applications.
