2. Lapping - Wikipedia

   en.wikipedia.org/wiki/Lapping

   Lapping machine. Lapping is a machining process in which two surfaces are rubbed together with an abrasive between them, by hand movement or using a machine. Lapping often follows other subtractive processes with more aggressive material removal as a first step, such as milling and/or grinding. Lapping can take two forms.

3. Precision glass moulding - Wikipedia

   en.wikipedia.org/wiki/Precision_glass_moulding

   Glass press production mould tool. Precision glass moulding is a replicative process that allows the production of high precision optical components from glass without grinding and polishing. The process is also known as ultra-precision glass pressing. It is used to manufacture precision glass lenses for consumer products such as digital ...

   This can be done, for example, with ring tools. Next, the lens surface is polished to its final form. Typically this is done by lapping—rotating and rubbing the rough lens surface against a tool with the desired surface shape, with a mixture of abrasives and fluid in between. Typically a carved pitch tool is used to polish the surface of a lens.

5. Abrasive machining - Wikipedia

   en.wikipedia.org/wiki/Abrasive_machining

   However, unlike conventional machining the grains are much smaller than a cutting tool, and the geometry and orientation of individual grains are not well defined. As a result, abrasive machining is less power efficient and generates more heat. [1] The grain size may be different based on the machining. For rough grinding, coarse abrasives are ...

6. Centerless grinding - Wikipedia

   en.wikipedia.org/wiki/Centerless_grinding

   A schematic diagram of the centerless grinding process. Centerless grinding is a machining process that uses abrasive cutting to remove material from a workpiece. [1] Centerless grinding differs from centered grinding operations in that no spindle or fixture is used to locate and secure the workpiece; [2] the workpiece is secured between two rotary grinding wheels, and the speed of their ...

7. Abrasive flow machining - Wikipedia

   en.wikipedia.org/wiki/Abrasive_flow_machining

   An abrasive flow machine normally includes two medium chambers equipped with hydraulic rams, a fixture for holding the workpiece, and a clamping system that holds all the components tightly together. [ 3 ] [ 1 ] Most machines allow for the loading of different types of abrasive medium, and include the capacity to adjust the pressure used in ...
