Miniature Ground Ball Screw Processing
ALM miniature ground screw threads are manufactured by an abrasive process that typically occurs in a horizontal setup,the material blank rotates on a long axis between two machining centers,while extremely hard abrasive cutters that are designed to cut a few threads at a time,carve out the threads from the cut blanks.
