Different wood cutting boards on a store shelf. A knife edge is a delicate structure and can easily be blunted by a too abrasive surface. It can also be chipped if used on a surface that is too hard. A good cutting board material must be soft, easy to clean, and non-abrasive, but not fragile to the point of being destroyed.
The largest machines used in wood processing, often called "Tub or Horizontal Grinders", may handle a material diameter of 2.4 m (8 ft) or greater, and use carbide tipped flail hammers to pulverize wood rather than cut it, producing a shredded wood rather than chip or chunk. These machines usually have a power of 150–750 kW (200–1,000 hp).
For example, melamine foam can remove crayon, marker pen, and grease from painted walls and wood finishings, plastic-adhering paints from treated wooden tables, and adhesive residue and grime from hubcaps. [3] If the surface being cleaned is not sufficiently hard, it may be finely scratched by the melamine material.
