In the field of machining industry, CNC machining is often mentioned, which is divided into three-axis CNC machining and four axis CNC machining. There are also five axis CNC machining. At present, it is widely used in the three-axis and four axis markets.
Three axis CNC machining: generally refers to three different directions of linear motion axis, such as up and down, front and back, left and right. Three axis can only process one face at a time, which is suitable for processing some plane parts. The technology of parts is simple and small batch parts processing.
Four axis CNC machining: add a rotation axis on the three axis, generally 360 ° Spin. But it can’t rotate at high speed. It can make the product multi-faceted processing by rotating, greatly improving the processing efficiency and reducing the clamping times. In particular, the processing of cylindrical parts is more convenient. And it can reduce the repeated clamping of the workpiece, improve the overall processing accuracy of the workpiece, simplify the process and improve the production efficiency. It is suitable for machining some box and complex precision parts.
The above is the difference between three-axis and four axis CNC processing. You may ask why five axis CNC processing is not mentioned. Although five axis CNC processing has outstanding advantages over four axis and three-axis CNC processing, not all products are suitable for five axis CNC processing, and those suitable for three-axis CNC processing are not necessarily suitable for five axis CNC processing. If the original three-axis products can be processed by five axis CNC processing, Not only will it increase the cost, but the effect is not necessarily good. Only reasonable arrangement, for the product to develop the appropriate machine tools, so as to play out the value of the machine itself.
