Stihl was founded in 1926 by Andreas Stihl, an innovator in early chainsaw production. Stihl says it is the world's best-selling brand of chainsaws and the only chainsaw manufacturer to make its own saw chains and guide bars. [4] Andreas Stihl AG is a privately held company owned by the descendants of Andreas Stihl.
The saw chain, or cutting chain, is a key component of a chainsaw. It consists of steel links held together by rivets , and superficially resembles the bicycle -style roller chain , although it is closer in design to a leaf chain.
So, the most-used method of cutting is plunge-cutting, by pushing the tip of the blade into the material. With this method, square cuts as small as the blade width can be achieved. Pushback can occur if a block shifts when nearly cut through and pinches the blade, but overall, the machine is less dangerous than a wood-cutting chainsaw.
The chain has to be properly matched to the guide bar and the saw. Chainsaw manufacturers specify a selection of suitable chains for each model of saw. Best safety requires that the chain is properly sharpened. One key sharpening parameter is the depth gauge setting. The depth gauge is the small steel protuberance in front of each cutting tooth.
Some troops leave the battlefield injured. Others return from war with mental wounds. Yet many of the 2 million Iraq and Afghanistan veterans suffer from a condition the Defense Department refuses to acknowledge: Moral injury.
To achieve optimal surface speed and cutting conditions, burrs are rapidly rotated at high speeds, often in the range of thousands or tens of thousands of RPM, which is typically the maximum speed supported by a given spindle. The cutters depicted in the image, being made of tungsten carbide, can withstand and operate at these elevated speeds.
Rotary cutting tools include drill bits, countersinks and counterbores, taps and dies, reamers, and cold saw blades. Other cutting tools, such as bandsaw blades, hacksaw blades, and fly cutters, combine aspects of linear and rotary motion. The majority of these types of cutting tools are often made from HSS (High-Speed-Steel).
