Press to Shape: Typically when referring to ceramic parts that are pressed to shape we are talking about parts that have their net shape coming off of the tooling. The only additional work required by the customer is what is necessary to fit them into your application. Most of our customers add value to our product via metallization or some type of assembly.

Green Machining: Green machining is a term used for machining ceramic material prior to firing. This operation allows us to add additional configurations to a part that has been either dry pressed, iso-pressed, or extruded that you normally could not obtain by these operations directly. They could be in the form of multiple stepped I.D.’s and O.D.’s as well as notches, cut outs, holes, or some type of shape on the sides of these already formed green parts.

Post Firing Grinding: This refers to grinding after the firing process. Once this material is fired, the only thing harder is diamond. The only way to change the shape or sizes of a fired part is to grind it, ream it, or hone it with some type of impregnated diamond tools (i.e., wheels, reamers, or hones). Ceramic parts can be reamed or ground after firing to achieve a closer tolerance than what can normally be achieved prior to firing.

O.D. / I.D. Grinding: ACCI has several centerless grinders that allow us to hold tighter tolerances on the O.D. We also have an O.D. I.D. grinder that also allows us to accomplish this same task on the O.D. and I.D. We have also reamed numerous I.D. holding tolerances to ± .0005.
