contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket. The most common options are 2, 3, or 4 flutes. The more flutes, the more cutting edges but the

Milling micro-EDM is a comparatively newer process, which eliminates the need for complex-shape electrodes usually required in die-sinking.In this process, usually tubular or cylindrical microelectrodes are employed to produce the desired complex shape by scanning. A cylindrical electrode rotates around its axis (Z-axis) with the scanning movements in X and Y directions.

Micro-milling — also known as fine milling and surface planing — is one of the best ways to restore the age-old, oxidized asphalt pavements. It is considered a better alternative to standard milling, as it produces finer results. While traditional milling leaves the surfaces rough, micro-milling provides a smoother and plainer surface to ...
