I have to say the tool post grinder works extremely. The only change I would make is to have a totally enclosed motor to keep out the grit. As the feed is given automatic, 0.8 micron finish may be achieved. A pressure vessel is defined as a container with a pressure LearnMech.Com is a Mechanical Project-oriented platform run by Sachin Thorat who is a B-Tech Graduate in Mechanical Engineering.
