Processing of automotive oil pipe joints

The CNC machining spindle for automotive parts is a parallel machining center called a horizontal machining center. Generally, a horizontal machining center has 3-5 motion coordinate axes, while a horizontal machining center has three linear motion axes and a rotational motion coordinate axis. The worktable of a horizontal machining center is mostly square and can complete the machining of all sides of the workpiece. What I just said is the basic structure of horizontal machining centers. So how do CNC machining manufacturers classify the structure of horizontal machining centers? There are various methods for classifying its structure, and the position of the spindle box is divided into: spindle box front hanging and spindle box side hanging; According to column classification, there are two types: fixed columns and moving columns; According to the shape classification of machine tools: positive T and negative T; According to the Z-axis classification, there are three types: Z-axis worktable cutting, Z-axis column cutting, and Z-axis slider cutting; However, in the industry, columns are classified according to their structure. There are two types of columns, namely moving columns and fixed column horizontal machining centers.
