In these machines, the tire is inflated using high volume, high pressure compressed air that flows into the tire around the tire bead rather than through the valve stem. When the tire has achieved the desired inflation pressure, the machine's inflation head moves away from the tire and the inflation process is completed. [7]
The machine is sometimes advertised as a "universal cutter-grinder", but the "universal" term refers only to the range of compound angles available, not that the machine is capable of sharpening the universe of tools. The machine is not capable of sharpening drill bits in the standard profiles, or generating any convex or spiral profiles.
While a cutter or spreader tool is designed for a particular application, a combination tool (also known as a combi-tool or spreader-cutter) combines cutting and spreading functions into a single tool. In operation, the tips of the spreader-cutter's blades are wedged into a seam or gap—for example, around a vehicle door—and the device engaged.
Tire factories start with bulk raw materials such as synthetic rubber (60% -70% of total rubber in the tire industry [2] [3]), carbon black, and chemicals and produce numerous specialized components that are assembled and cured. The tire is an assembly of numerous components that are built up on a drum and then cured in a press under heat and ...

Some companies such as Les Schwab claim that microsiped tires reduce tire friction heat and tire wear and extends the life of the tire. [7] Both Bridgestone and Michelin sell snow tires that are siped at the factory, while Saf-Tee Siping and Grooving sells machines that can sipe most standard vehicle tires. Siping can also be done by hand.
Linear cutting tools include tool bits (single-point cutting tools) and broaches. 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 ...
In the late 1970s, South Africa was involved in an international controversy over apartheid and the South African Border War in Angola. As a result, it was subject to an international arms embargo and had to, out of necessity, design and manufacture its own weapons. [1] The SS-77 was developed to replace the FN MAG. It was designed in 1977 by ...
