Applications Cylinder Bore Gauge

Applications bore gauge is not measuring application inside micrometer, because bore gauge has a long stalk tool holder and a dial gauge to read the measurement results, so in places that can not use the narrow bore gauge, for example, is a bore for camshaft bushing. Cylinder Bore gauge is widely used to measure the diameter of the cylinder liner, ...

Electrical Grounding Function

Electrical relating to the nature of the flow of electric current / electrons. Naturally, the nature of the flow of electric current in a conductor or conductors of electricity such as the flow of water coming from upstream (the mountains) to downstream (the ocean). Water that is at higher altitudes always will flow to a lower place. Water will always ...
