Precision Surface Grinding With A Ded-Tru Machine
Over the years I have used a variety of machines to make round cores and core pins, but the Ded-Tru is probably the best inexpensive toolroom precision grinder. I am sure there are high-end CNC grinders available that can do the job faster and maybe better, but, for the money, the Ded-Tru is a great machine.
Not that I like running it, in fact, I really don’t! However, you gotta do what you gotta do to get the job done, right? The reason I don’t really like using it is because you have to just stand there and do the same procedure over and over again, without ever varying the method.
On the other hand, this grinder can do some very impressive work. It also requires a high degree of skill and patience in order to be used efficiently. Not just anybody can walk up to it and figure out the proper set-up procedures; as well as the endless subtleties of form grinding and concentricity.
