The cutting blades of a small electric chipper. The blades can be removed, by loosening the bolt in the center, to facilitate sharpening or for replacement. Much larger machines for wood processing exist. "Whole tree chippers" and "Recyclers", which can typically handle material diameters of 60–180 cm (2–6 ft) may employ drums, disks, or a ...
A screw-type wood chipper contains a conical, screw-shaped blade {citation needed}. The blade rotation is set parallel to the opening so wood is pulled into the chipper by the spiral motion. Screw-type, also called high-torque rollers, are popular for residential use due to being quiet, easy to use and safer than disk and drum types. [15] [17]
Scratcher chain, like the teeth on a hand saw, simply uses a multitude of teeth to prevent individual teeth from sinking too far in without undue pressure on the bar. Chipper chain, and all subsequent designs, incorporate a depth gauge (also known as a "raker" [1]) on each cutter link to limit depth of cut on each tooth. This has two distinct ...

The NACA four-digit wing sections define the profile by: [2] First digit describing maximum camber as percentage of the chord.; Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord.
The first announcement of the Blade of the Immortal anime was in Kodansha's Afternoon magazine. The series aired from July 14, 2008 to December 29, 2008 on AT-X. Seven DVD compilation volumes were released by Pony Canyon between August 29, 2008 and February 27, 2009, followed by a DVD-box on November 11, 2010. [2]
The turbine blades have a golden colour in this engine cutaway. A turbine blade is a radial aerofoil mounted in the rim of a turbine disc and which produces a tangential force which rotates a turbine rotor. [2] Each turbine disc has many blades. [3] As such they are used in gas turbine engines and steam turbines.
