Valve grinding is traditionally not the most important repair process for some engine mechanics. Indeed, why grind them if you take more abrasive paste and lap whilst all not be erased. Meanwhile, high-quality grinding of the valve chamfer is extremely important, without it it is impossible to perform high-quality repair of the cylinder head. In addition, a machine for processing seats can only work in tandem with a machine for grinding valves, and if someone, through ignorance or thoughtlessness, decides to break this pair, then his next step will be a return to grandfather’s lapping technologies.
But this is not the entire list of problems that await those who want to use the right technologies, since valve grinding machines differ so fundamentally that not every machine can normally grind all valves in a row. Hence the traditional question of how not to get into trouble, not to fall into a puddle, not to get caught on a rusty lure or a beautiful wrapper, but to make the right choice from dozens of possible options, is still relevant when … …
