Bench model version with central grinding head and horizontal movable specimen platform. These practices specify procedures for laboratory rock core test specimen preparation of rock core from drill core and block samples for strength and deformation testing and for determining the conformance of the test specimen dimensions with tolerances established by this practice.

Suitable to grind up to satm mm concrete astm d4543, 2x x mm concrete astm d4543, 2x or 4x rock For curatorial issues that should be followed before and during specimen preparation refer to Practices D and to the specific test standards in 2.

Best effort in surface preparation refers to the use of a well-maintained surface grinder, lathe or lapping machine by an experienced operator in which a reasonable number of attempts has been made to meet the tolerances required x4543 this procedure.
