Heavy grinding machine platform

The invention discloses a heavy grinding machine platform, and belongs to the technical field of machine tool equipment. The platform mainly structurally comprises a base, an oil return groove, an oil injection sliding block and a guide rail. Wherein a pair of oil return grooves are formed in the top of the base in parallel in the length direction, oil guide rails are arranged in the oil return grooves, and the two guide rails are kept parallel. On the basis, a plurality of oil injection sliding blocks are installed on the guide rail in a sliding mode, the oil injection sliding blocks are used for being fixedly connected with a machining platform in a threaded mode, and therefore the machining platform can move back and forth along the guide rail. In addition, the bottom of the oil injection sliding block is embedded into the guide rail in a sliding mode, and an injection hole is formed in the top of the oil injection sliding block. When the machining platform moves, lubricating oil is injected from the injec
