This equipment is an Engine Block and Head Surfacing Grinding Machine (Surface Grinding Machine) produced by AMC-SCHOU (Model SG 1400). Primary Function: This machine is used in lathes and engine rebuilding workshops to perform a "milling" or "grinding and smoothing" operation on the engine's metal surfaces to ensure their complete and precise flatness. Key Uses: 1. Surfacing the Cylinder Head: When a vehicle is exposed to high heat, the bottom surface of the cylinder head can warp or distort. This machine removes a very thin layer of metal to restore the surface to perfect flatness. 2. Surfacing the Engine Block: Used to smooth the top surface of the engine block where the cylinder head attaches. 3. Ensuring a Tight Seal for the Head Gasket: Provides a high degree of smoothness and flatness, preventing oil from mixing with coolant or combustion pressure from leaking after engine overhaul.
