D-honer engineers [india] provides face lapping machine for connecting rods. There are two configuration are like : the first type of lapping [traditionally called grinding], typically involves rubbing a brittle material such as glass against a surface such as iron or glass it self [also known as the "lap" or grinding` tool] with an abrasive such as aluminum oxide, emery, silicon carbide, diamond, etc., in between them. This produces microscopic conchoidal fractures as the abrasive rolls about between the two surfaces and removes material from both. The other form of lapping involves a softer material for the lap, which is "charged" with the abrasive. The lap is then used to cut a harder material the work piece. The abrasive embeds within the softer material, which holds it and permits it to score across and cut the harder material. This will results a polished surface such as a polishing cloth on an automobile, or a polishing cloth or polishing pitch upon glass or steel.
