Cylinder Honing and Surface Finish Analysis

bonnet hood whatever you want to call it to the ca so we have a lot of room to play in there that's freaking sweet it's gonna be nasty man it's gonna be really nasty so we're to uh if we jump back to the assembly process yep what happens after we go here once we come out of this machine going to go over to the cylinder hone [Music] so going to the cylinder hone this block just got finished up but you can see here very consistent cross hatch we [Music] put a lot of focus on the surface finish as we were talking about earlier i mean that's uh you've got your geometry of the cylinder bore how round and straight it is and then you have the surface finish that you're actually achieving so with this it's basically a cnc hone it can auto dwell so it can sense taper in the cylinder and and dwell in those areas to help get it as straight as possible and then kind of by default this honing head has a diamond abrasive which creates just a very consistent and round cylinder again we can we can get it round and straight out to four decimal places we've got our different torque plates for different applications this simulates the cylinder head being torqued onto the block when you torque the when you torque the torque plate or a cylinder head onto the engine block it actually distorts it'll distort the cylinder in a certain way that's and then we want to hone it straight and round in that distorted state so when we bolt the cylinder head on it goes back to around so when we take the torque plate off it goes out of round then when we bolt the cylinder head back on it distorts back to a round condition round and straight talking very very minimal and you know fractions of an inch but all that matters the prophylometer that we were talking about earlier is just this guy right here so this little ruby head at the end of this deal here we put that onto the clean cylinder wall and that allows us to get different parameters of the
