The ACER SUPRA-618 series, including the SUPRA-618 and SUPRA-618H models, stands as a top-tier choice for high-precision surface grinding tasks. Built with a robust high-tensile Meehanite casting and a sturdy cast-iron base, the machine is engineered to absorb vibration, ensuring superior rigidity and stability throughout the grinding process. The machine boasts a generous 6-inch by 18-inch table size with a longitudinal travel of 20 inches and a cross-feed travel of 7 1/2 inches.

Accuracy is paramount, achieved through a waist-side down feed mechanism and a clear vertical graduation of 0.0001 inch via a direct dial for fine adjustments. The table system utilizes a smooth-operating ball rolling table design, while the cross-feed way features a double V Turcite-B construction to minimize friction and ensure long-term, precise travel. Powering the process is a 3 HP motor driving an 8-inch by 1/2 inch grinding wheel at 3,450 RPM. Standard features enhancing the operator’s experience and machine longevity include an automatic lubricator, a wheel balancing base and arbor, a diamond dresser, and a halogen work light, all integrated into a CE standard electric package.
