Granite surface plate has many advantages over cast iron surface plates: - Twice as hard as cast iron. - Free from wringing, so there is no interruption of work. Free from burrs or protrusions because of the fine grain structure and insignificant stickiness; this ensures high degree of flatness over a long service life and causes no damage to other parts or instruments. - Trouble-free operation for use with magnetic materials. - Long life and rust-free, resulting in low maintenance costs.
