Complex curved surface stone and processing method

The invention relates to a complex curved surface stone and a processing method, belongs to the technical field of building decoration, and aims to solve the problems of difficulty in processing of a special-shaped stone model in a multi-curved surface stone model space, high transportation cost, low field installation precision and the like. The stone composite honeycomb plate comprises a stone composite honeycomb plate structure formed by a natural stone flat plate, a stainless steel wire mesh layer, a glass fiber reinforcing cloth layer and a honeycomb aluminum plate layer which are fixedly connected in sequence through a binder. The machining method comprises the steps that firstly, the natural stone flat plate is fixed to a machine tool with the back face upward; 2, machining the reverse side of the stone by adopting a single-head carving machine, and reserving temporary supporting legs; thirdly, the stone is fixed to the machine tool with the front face upwards; fourthly, the front face of the stone is
