Demyelinating disease. A demyelinating disease is any disease of the nervous system in which the myelin sheath of neurons is damaged. This damage impairs the conduction of signals in the affected nerves. In turn, the reduction in conduction ability causes deficiency in sensation, movement, cognition, or other functions depending on which nerves are involved.
For other uses, see Reamer (disambiguation). A reamer is a type of rotary cutting tool used in metalworking. Precision reamers are designed to enlarge the size of a previously formed hole by a small amount but with a high degree of accuracy to leave smooth sides.
Coolant feeding reamers: Coolant induced thru the reamer should be utilitized when possible. Benefits include better finishes, superior tool life and the ability to increase speeds and feeds. Speeds and Feeds: Reaming is a finishing operation and the correct combination of speed and feed is critical to tool life.
