Speed and feed of 5 axis CNC machining

The speed and feed of 5 axis CNC machining is a highly professional problem. The actual processing parameters of CNC mainly include spindle speed, tool diameter, feed (divided into XY and Z), and feed rate. Many factors affect processing parameters. The machine bed structure, spindle size (BT30, BT40, BT50, etc.), the tool material used, the coolant method, and the appearance requirements of the workpiece will all affect the actual processing parameters.

The bed of 5 axis CNC machining consists of rigid rail and linear rail. The stern rail has good rigidity and is suitable for steel parts. However, the linear rail is specialized in processing aluminum parts. The linear rail has a fast-moving speed, but the rigidity is not as good as the handrail. Therefore, the hard-track machine tool processing aluminum parts has an advantage over the linear track in the amount of back-grabbing (XY-direction) and bottom-grabbing (z-direction) and the feed rate.

The spindle taper hole of 5 axis CNC machining is divided into BT30, BT40, BT50. Among them, BT30 is the smallest, and BT50 is the largest. The taper hole of the spindle determines the size of the spindle and the rigidity of the spindle, and the outer diameter of the tool holder. The spindle taper hole determines the size of the tool's XY direction and Z direction. The larger the spindle taper hole and the larger the tool holder, the better the rigidity and the larger the feed parameters.

The processing cooling system of 5 axis CNC machining is not complicated. According to the cooling effect, it is divided into oil cooling and water cooling. Oil cooling is the best, but the cost is high, and water cooling is inferior, but the cost is low. Only some unique processes require air cooling. It also has an impact on processing parameters.
