Case of vitrified CBN grinding pins for turbocharger workpiece grinding
What is turbocharger ?
A turbocharger works by taking power from exhaust gases that pass through another turbine that draws in air from a compressor, whereas in a conventional engine the exhaust would be expelled into the atmosphere. More air intake means better mixing of air and fuel during combustion, producing more power with each stroke of the engine.
