MULTI-DIAMOND CUTTING TOOL ASSEMBLY FOR CREATING MICROREPLICATION TOOLS

摘要

In one embodiment, a cutting tool assembly (10) used for creating grooves in a microreplication tool (72a) is described. The cutting tool assembly includes a mounting structure (10) and multiple diamonds (12, 13) mounted in the mounting structure (14). For example, first and second tool shanks having first (17)and (18) second diamond tips can be positioned in the mounting structure (14) such that a cutting location of a diamond cutting tip of the first tool shank is a defined distance from a cutting location of a diamond cutting tip of the second tool shank. The defined distance (y) may correspond to an integer number (x) of pitch spacings, and may be accurate to within a tolerance of less than 10 microns.
