Honing (metalworking)

Honing is an abrasive machining process that produces a precision surface on a metal workpiece by scrubbing an abrasive stone against it along a controlled path. Honing is primarily used to improve the geometric form of a surface, but may also improve the surface texture.

Typical applications are the finishing of cylinders for internal combustion engines, air bearing spindles and gears. There are many types of hones but all consist of one or more abrasive stones that are held under pressure against the surface they are working on.

In terms of sharpening knives, a honing steel does not actually hone knives, but simply realigns the metal along the edge.

Other similar processes are lapping and superfinishing.

Honing stones

Honing uses a special tool, called a honing stone or a hone, to achieve a precision surface. The hone is composed of abrasive grains that are bound together with an adhesive. Generally, honing grains are irregularly shaped and about 10 to 50 micrometers in diameter (300 to 1,500 mesh grit). Smaller grain sizes produce a smoother surface on the workpiece.

Chone Monastery

Chone Monastery (Tibetan: Wylie: ; Chinese: Jonê; Pinyin: Zhuōní), also Chone Gonchen Ganden Shedrubling, or Choni Monastery was originally a Sakya monastery. It is situated adjacent to Chone Town, Jonê County, Gannan Tibetan Autonomous Prefecture, Gansu Province, China, at an altitude of about 2,610 m (8,563 ft).

History

Chone Monastery was originally founded in 1269 by Drogon Ghogyel Phakpa (1235–1280) and his Mongol patron, Kublai Khan or (Qubilai Qan), in 1269 CE as a Sakya monastery.

Chone Monastery was part of a separate kingdom formed, according to legend, after its invasion by Chinese warriors who migrated across the mountains from Szechuan conquering the local tribes in 1404. The Yongle Emperor (May 2, 1360 – August 12, 1424) named one of them hereditary chief, bestowing the name of "Yang" and an imperial seal upon them and the prince established a palace on the north bank of the Tao River. The Yang family, continued to rule over 48 unruly Tibetan clans in Chon-ne as a semi-independent kingdom from the early 15th century for 23 generations, until 1928, when it was placed under the control of the Lanchow government.
