Conventional lapping technology can be divided into two basic categories: loose abrasive grinding (slurry lapping) or fixed abrasive lapping. In slurry lapping the abrasive is in the form of an aqueous slurry of abrasive minerals (typically alumina or silicon carbide) and the lapping surface is the machine platen (typically cast iron).

The fixed grain of a geometrically indefinable cutting shape acts like a plow (fig. 3) and material is removed by micro-grooving /-cutting (fig. 4). The chip formation occurs by exceeding the shearing strength. Fine Grinding vs Lapping Kinematics of the Fine Grinding Process. Fine Grinding generally follows the same kinematic principle as lapping.
A European Sales group initially operating from Slough, England, moved to a new facility in Plymouth, England in 1972 where manufacturing of lapping machines commenced and continues to grow with the additional supply of dual face, optical polishing, spherical equipment, consumables and service for .
Apr 27, 2004· Throughput averages between 200 and 300 parts an hour. Removing the typical 0.020 to 0.025 inches of stock from a tungsten carbide insert with a flat-lapping machine usually requires 2 to 3 hours because the material is so hard. But flathoning machines are unlike conventional fixed abrasive grinders used for sizing components.
Depending upon the application, fine grinding technology utilizes fixed abrasive diamond or CBN suspended in resin, metal, and vitrified bonds to grind a wide range of materials to very tight specifications. Fine grinding technology uses similar planetary machine designs and kinematics to traditional lapping technology, with several significant ...

Although the lapping process is less damaging than grinding, there are two regimes of lapping: free abrasive lapping and fixed abrasive lapping. Free Abrasive Lapping is when abrasive slurry is applied directly to a lapping plate (e.g. cast iron). This is perhaps the most accurate method for producing specimens and causes the least amount of ...
