Long Dowel Pins Knurled Shape Locating Alloy Metal Micro Machining

The long dowel pins inserted into receiving holes, pins hold together parts of an assembly with friction. They may also be used as location pins. These pins are common in the automotive and aerospace industries as well as in furniture making. Ever Hardware provides custom-made long dowel pins and customizable packaging.

Machining is a part of the manufacture of many metal products, but it can also be used on materials such as wood, plastic, ceramic, and composites. A person who specializes in machining is called a machinist. A room, building, or company where machining is done is called a machine shop. Much of modern-day machining is carried out by computer numerical control (CNC), in which computers are used to control the movement and operation of the mills, lathes, and other cutting machines. The three principal machining processes are classified as turning, drilling, and milling. Other operations falling into miscellaneous categories include shaping, planing, boring, broaching, and sawing.

Heat treating is a group of industrial and metalworking processes used to alter the physical, and sometimes chemical, properties of a material. The most common application is metallurgical. Heat treatments are also used in the manufacture of many other materials, such as glass. Heat treatment involves the use of heating or chilling, normally to extreme temperatures, to achieve the desired result such as hardening or softening of a material. Heat treatment techniques include annealing, case hardening, precipitation strengthening, tempering, normalizing, and quenching. It is noteworthy that while the term heat treatment applies only to processes where the heating and cooling are done for the specific purpose of altering properties intentionally, heating and cooling often occur incidentally during other manufacturing processes such as hot forming or welding.
