Descrição:	Melchiorre 600 máquina nova Copper plate for lapping machine. Dia 600mm, NEW, make: Melchiorre, Mimu Machine Tools Gussago BS Italy, Lapping is a [machining](https://en.wikipedia.org/wiki/Machining) process in which two surfaces are rubbed together with an [abrasive](https://en.wikipedia.org/wiki/Abrasive) between them, by hand movement or using a machine., This can take two forms. The first type of lapping (traditionally called [grinding](https://en.wikipedia.org/wiki/Grinding_machine)), involves rubbing a brittle material such as [glass](https://en.wikipedia.org/wiki/Glass) against a surface such as [iron](https://en.wikipedia.org/wiki/Iron) or glass itself (also known as the lap or grinding tool) with an abrasive such as [aluminum oxide](https://en.wikipedia.org/wiki/Aluminum_oxide), [jewellers rouge](https://en.wikipedia.org/wiki/Jeweller%27s_rouge), [opticians rouge](https://en.wikipedia.org/wiki/Cerium(IV)_oxide), [emery](https://en.wikipedia.org/wiki/Emery_(mineral)), [silicon carbide](https://en.wikipedia.org/wiki/Silicon_carbide), [diamond](https://en.wikipedia.org/wiki/Diamond), etc., between them. This produces microscopic [conchoidal fractures](https://en.wikipedia.org/wiki/Conchoidal_fracture) as the abrasive rolls about between the two surfaces and removes material from both., The other form of lapping involves a M536876 softer material such as [pitch](https://en.wikipedia.org/wiki/Pitch_(resin)) or a [ceramic](https://en.wikipedia.org/wiki/Ceramic) for the lap, which is charged with the abrasive. The lap is then used to cut a harder materialâthe workpiece. The abrasive embeds within the softer material, which holds it and permits it to score across and cut the harder material. Taken to a finer limit, this will produce a polished surface such as with a polishing cloth on an automobile, or a polishing cloth or polishing pitch upon glass or steel. seller offer No. resale 2180
