	The structural parts are manufactured from high quality cast iron, heat treated and stress relieved for maximum material stability without deformation. The grinding wheel spindle and the regulating wheel spindle are precision machined from Nickel Chromolybedenum alloy steel (SNCM-220). Both spindles are subject to various heat treatments, making the machine ideal for heavy duty machining and high precision grinding. The upper slide can be swiveled +5~-5 High precision micrometric feed adjustment in 0.001 mm. The feed screw employs high precision ball screws, normalized and high frequency heat treated for maximum wear resistance.   SC-18 Grinding diameter (standard) Ø1~Ø40 mm Grinding diameter (special) Ø30~Ø60 mm Grinding wheel size Ø445 x 205 x Ø228.6 mm Regulating wheel drive 2HP x 6P Gear Box     top SPECIFICATIONS SC-18S Grinding Wheel Standard grinding range (Die.)
