Today there are many ways to process metal, but it is milling that is used most often.
The reason for this situation is that it is this method of metal processing that is the most reliable. Milling work is the processing of parts on specially provided milling machines. Milling work on metal is performed as on manual machines, and on a special vertical CNC machining center.
The milling machines are equipped with special cutters. The cutter is a multi-edge tool. Milling work is carried out with different types of surfaces, among which one can distinguish: vertical, inclined, shaped, horizontal and others. Milling work can be performed in two ways, passing or counter. The difference lies in the way the workpiece is fed. For example, if you use the downhill cutter motion to match the workpiece motion, this method helps to reduce wear on the machine and provides a smooth surface after milling.
If you use the counter method, the workpiece moves in the opposite direction to the edge of the cutter. The counter method can generate vibrations that can degrade surface quality, but this method has worked well for workpieces.
Depending on which tool is used for milling work, there are such types of milling as: end, shaped or face. End milling is used when machining pockets, grooves, windows, wells, undercuts, grooves. Shaped milling is used in profile processing. Face milling is used when machining large parts with large surfaces.
Among the materials available for processing on milling machines are such as: iron, stainless steel, duralumin, aluminum, bronze and others. Milling work on iron processing is less labor intensive than work on processing polymer, stainless steel, bronze or aluminum. On milling machines, you can carry out such work as: milling surfaces, ledges, grooves, helical surfaces and cutting off the workpiece.
Among all methods of metal processing, milling is the most highly productive. Milling is one of the oldest, but also the most time-tested, processing methods. Therefore, in our time it is the most demanded.
