The one workpiece (5) is ground with the grinding worm (4), while on the other spindle (6b) a ground workpiece (8a) is exchanged for an unmachined part (8b) using a loader (10).

Additionally, the strength of the ground surface is enhanced after processing.

The opposite, second surface of the substrate is then ground and polished until it is substantially transparent.

At least one of the extremities of the discarded winding core is internally ground on a predetermined grinding distance to remove the crimping portion and provide a ground portion thereon.

During manufacturing the higher surface of the top surface is ground to a precision height.

The second side is background and secured to a dicing tap.

The recess (2e) is formed by turning, and the inner surface of the recess (2e) is cut or ground after the hardened layer (20) is formed.

They may be convex, and when inserted into a milled concavity, are immediately mechanically stable.

A top surface of the molded compound is abrasively ground and then deposited with an adhesion layer (123, 124, 224).

The first fluid channel (12) passes axially through the first flange (10) to open into the ground surface (18).

It is definitely better to place it on a prepared natural tooth.

A casing exit joint with an easily milled and low density barrier.

Optionally, tension is applied to the ground strip to enhance material handling and control.

The portion (P) is cured, and the surface ground and polished to provide a plurality of cutting edges (18).

The ground strip may be treated with acid to remove ground surface material and to condition the strip.
