A machining center with parallel spindles is called a horizontal machining center. Generally, a horizontal machining center has 3-5 motion coordinate axes. Common horizontal machining centers are three linear motion axes plus one rotary motion coordinate axis. , The worktable of the horizontal machining center is mostly square, which can complete the processing of all sides of the workpiece by clamping the workpiece at one time. What I just said is the basic structure of the horizontal machining center, so how to classify the structure of the horizontal machining center? There are various structural classification methods. There are two types of headstock positions: front-mounted headstock and side-mounted headstock; there are two types of columns: fixed column and movable column; there are two types according to the shape of the machine tool. : There are two types of positive T and inverted T; there are three types according to Z-axis feed: Z-axis table feed, Z-axis column feed, and Z-axis ram feed; and in the industry, they are classified by column. The editor will introduce the structure classified by column today. I just said that there are two types of columns, namely, moving columns and fixed column horizontal machining centers. Let’s introduce their structure and characteristics below.
The structure and characteristics of the fixed column horizontal machining center
There are three types of horizontal machining centers with fixed columns. The column is fixed and the spindle box moves in the Y direction. The worktable moves in Z and X directions. The spindle box moves in Y and Z directions. The worktable moves in X direction. One kind; the spindle box moves in the Y and X directions, and the work table moves in the Z direction; this is the fixed column horizontal machining center. The horizontal machining center of this type of structure has good structural rigidity, high machining accuracy, and installation adjustment Convenience and other features.
The structure and characteristics of moving column horizontal machining center
There are many types of horizontal machining centers with moving columns. There are three types, all of which are moving columns. The workbench is fixed, the column moves in the X direction, and the headstock is hung on the side to move in the Z and Y directions; the workbench is moved in the Z direction, the column is moved in the X direction, and the headstock is moved in the Y direction; the workbench is moved in the X direction, and the column is moved in the Z direction. Movement, the headstock moves in the Y direction; these three types are the moving column horizontal machining center. The movable column horizontal machining center has high rigidity, large load capacity, and is suitable for heavy cutting and rough machining.
