Amtech Tool and Machine offers both CNC and Manual Milling Machines. They can process a wide range of parts from small individual to large, heavy-duty gang milling operations. The mills use rotary cutters, often with multiple cutting points, to remove material from a workpiece. As the milling cutter enters the workpiece, the cutting edges repeatedly cut into and exit from the material, shaving off chips from the workpiece with each pass. There are two different classes of milling, first is face milling, the cutting occurs primarily at the end corners of the miller cutter. It’s used to cut flat surfaces into the workpiece or flat-bottomed cavities. The second class is peripheral milling which cuts primarily along the circumference of the cutter so the cross section of the milled surface ends up receiving the shape of the cutter. With this class the blades of the cutter appear to be scooping out material from the workpiece. This is best used in cutting deep slots, threads and gear teeth.
