MICRO FLAT 48" X 60" MANUAL LATHE

Technical Description

The MICRO FLAT 48" x 60" Manual Lathe Surface Plate is a precision metrology instrument engineered for industrial measurement and inspection applications. Constructed from high-quality granite with a pink grade designation, this expansive work surface measures 48 inches by 60 inches and features a substantial thickness of 10 1/2 inches, ensuring exceptional rigidity and thermal stability during precision measurements. The surface plate achieves the flatness specifications required by national and international standards for Grade B precision work, making it suitable for complex geometric accuracy verification and machine tool calibration. The granite material provides superior hardness, typically ranging from 5.6 to 7 on the Mohs scale, delivering outstanding wear resistance and surface durability for extended operational life. Mounted on a heavy-duty cart equipped with casters, the complete assembly reaches an overall height of 38 inches with a ledge height of 2 3/8 inches, facilitating ergonomic operator access and convenient mobility throughout the workshop. The approximately 3000-pound mass provides the necessary stability and vibration damping critical for maintaining measurement accuracy during prolonged use. The smooth, jewel-like quartz bearing points inherent to granite surfaces protect dimensional integrity and surface finish of precision components being inspected. This configuration is ideal for aerospace, automotive, and precision manufacturing environments requiring reliable, repeatable surface plate performance for inspection, gauging, and squareness testing operations.
