Pulping is mechanical; the main method is the thermomechanical process, in which wood particles are steamed and then reduced to fibres by the action of special mills.
The study of the design and manufacturing of special milling processes is important in the development of a mold with complex curved surfaces.
A special milling machine working on toroidal coordinates was developed, tested and built in order to accurately mechanise the grooves in the monolithic frame.
Caryopsis, also called grain, specialized type of dry, one-seeded fruit (achene) characteristic of grasses, in which the ovary wall is united with the seed coat, making it difficult to separate the two except by special milling processes.
Milling machines are available in a variety of designs that can be classified as the following: (1) standard knee-and-column machines, including the horizontal and the vertical types; (2) bed-type or manufacturing machines; and (3) machines designed for special milling jobs.
Being CAD/CAM fabricated from special milling blocks, the design of the scaffold could easily be tailored to meet the demands of different fields.
The company buys tire scraps that are one-quarter to one-inch chips and freezes them using liquid nitrogen, then puts them through special milling machines that can operate at extremely low temperatures to produce the right size powder particles.
Aveeno has been formulating products with oatmeal since 1945, when the founders developed a special milling process to create colloidal oatmeal, and then launched the brand's first-ever product: Aveeno Soothing Bath Treatment.
In 1983 and 1984, a Toshiba subsidiary, Toshiba Machine Co., and a state-owned Norwegian arms firm, Kongsberg Vaapenfabrikk, secretly sold the Soviet Union special milling machinery and computer equipment that have allowed it to produce quieter submarines, making it more difficult for Western monitors to detect them.
In modern factories, it may be estimated that an effect of about 85percentt is attained at the first rasping; at these production levels, however, it is economical to submit the pulp to a second crushing process, either in a second rasper or in special mills where the pulp is ground between stones.
