A cutting machine particularly for cutting plates of plastic material and non-ferrous metal sheets, having a cutting blade rotating in such a direction that its cutting rim enters into a guard casing at the cutting place, said guard casing having a rim closely adjacent said cutting blade at least near the cutting place, and said rim being pressed against the material to be cut near said cutting place thereby preventing bending, deformation and splitting of said material by the cutting forces.
