Diamond turning

Diamond occurring in the blue ground of volcanic pipes as well as freshly pulverized diamond show hydrophobic behavior. This is used in its isolation by flotation. Diamond found in sediments is hydrophilic, however. According to Plaksin and Alekseev (154), hydrophobic diamond turns slowly hydrophilic on storing with exposure to air. Hofmann (155) reported that fine particle size diamond forms stable suspensions in dilute ammonia after treatment with calcium hypochlorite. It seems rather obvious that formation of surface oxides is responsible for the hydrophilic properties. [Pg.220]

A thermodynamic system is in thermodynamic equilibrium if none of its macroscopic properties is changing over time. (Note Some states that appear not to be changing may not be true equilibrium states because the changes are too slow to be observed, for example, diamond turning into graphite.)... [Pg.518]

Ultraprecision is defined as the state, quality, or condition of being extremely precise. Therefore, an ultraprecision machine is characterized by extremely accurate motion, dimensions, or machining capability. Technical terms with ultraprecision include ultraprecision machine tool, ultraprecision diamond turning machine, ultraprecision machining technology, ultraprecision metrology, etc. [Pg.1273]

The large optics diamond turning machine (LODTM), built at the Lawrence Livermore National Laboratory in 1970s, is famous in the field of ultraprecision machine tools. Structural stability is one of the most important issues in designing an ultraprecision machine tool. Figure 2 shows the basic design concept of a thermally and dynamically stable ultraprecision machine tool structure (e.g., Shinno et al. 1992). [Pg.1274]

Deterministic mechanical nanometric machining. This method utilizes fixed and controlled tools, which can specify the profiles of three-dimensional (3D) components by a well-defined tool surface and path. The method can remove materials in amounts as small as tens of nanometers. It typically includes diamond turning, miCTomilling and nano/microgrinding, etc. [Pg.214]
