Gussago BS Mimu machine tools, Lapping is a
[machining](en.wikipedia.org/wiki/Machining) process in which two
surfaces are rubbed together with an
[abrasive](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](en.wikipedia.org/wiki/Grinding_machine)), involves rubbing
a brittle material such as [glass](en.wikipedia.org/wiki/Glass)
against a surface such as [iron](en.wikipedia.org/wiki/Iron) or glass
itself (also known as the lap or grinding tool) with an abrasive such
as [aluminum oxide](en.wikipedia.org/wiki/Aluminum_oxide), [jewellers
rouge](en.wikipedia.org/wiki/Jeweller%27s_rouge), [opticians
rouge](en.wikipedia.org/wiki/Cerium(IV)_oxide),
[emery](en.wikipedia.org/wiki/Emery_(mineral)), [silicon
carbide](en.wikipedia.org/wiki/Silicon_carbide),
[diamond](en.wikipedia.org/wiki/Diamond), etc., between them. This
produces microscopic [conchoidal
fractures](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 softer material such M51236876
as [pitch](en.wikipedia.org/wiki/Pitch_(resin)) or a
[ceramic](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., Diameter: 600
