The ACER SUPRA-1428AHD is a high-performance, fully automatic hydraulic surface grinder engineered for demanding industrial environments requiring large capacity and exceptional precision. This machine boasts a substantial 14-inch by 28-inch grinding capacity, making it ideal for a wide range of medium to large workpieces. The foundation of its stability and accuracy is a heavy-duty Meehanite casting that effectively absorbs vibrations, ensuring consistent results.

Both the longitudinal and cross-feed movements are guided by double V ways coated with Turcite-B, which provides smooth, low-friction travel and significantly enhances machine longevity and precision. Powering the grinding process is a robust 7-1/2 HP spindle motor that drives a 14-inch by 2-inch grinding wheel at 1,800 RPM. The auto downfeed mechanism enables precise, repeatable vertical increments from 0.0001 to 0.001 inches, allowing for automated roughing and finishing cycles. The table’s hydraulic drive system ensures smooth and consistent longitudinal travel. Standard features include an automatic lubricator, a wheel balancing base and arbor, a diamond dresser, and a halogen work light, all integrated within a CE standard electrical system, making the SUPRA-1428AHD a comprehensive solution for automated, high-volume precision grinding.
