Processing characteristics and difference comparison between cnc horizontal machining center and vertical machining center


Author: MULAN -Plastic Molding Manufacturer

The cnc machining center is a high-precision machining equipment integrating automation, intelligence, compound machining and high speed. Among them, the horizontal and vertical machining centers are the most widely used models at present. So what are the advantages and disadvantages of the structural characteristics and technical performance of the two? Below, Hongweisheng Precision Technology will explain it in detail for you, let’s take a look together. 1. The characteristics of the machine tool of the horizontal machining center The horizontal machining center is relative to the vertical machining center. Its main shaft is a machining center in a horizontal state, and it usually has a rotary table with automatic indexing. It generally has 3 ~5 motion coordinates, the common one is three linear motion coordinates plus one rotary motion coordinate. After the workpiece is clamped once, it can complete the processing of the other four surfaces except the mounting surface and the top surface. The current horizontal machining center There is already a five-axis and five-linkage model, which can process the other five surfaces except the bottom surface, that is, the mounting surface at one time.

The horizontal machining center is most suitable for adding box parts. Compared with the vertical machining center, the horizontal machining center is easy to remove chips during machining, which is beneficial to the machining. Because the structure of the horizontal machining center is good, it can process some large and complex parts. It can be said that the vertical The workpieces that cannot be processed by the machining center can be processed on the horizontal machining center. But there are advantages and disadvantages. Compared with the vertical machining center, the horizontal machining center has the disadvantages of complex structure and high price.

2. Machine tool characteristics of vertical machining center Vertical machining center refers to the machining center whose main shaft is in a vertical state. , sets, and plate parts, it generally has three linear motion coordinate axes, and its X, Y, and Z three-axis servos are controlled by direct connection. It is a semi-closed-loop vertical machining center. It has a large guide rail load, a wide span, It has the advantages of high precision, compact and reasonable structure and external dimensions, etc. The main shaft is driven by a servo motor through a synchronous belt, which can realize one-time clamping of various discs, plates, shells, cams, molds and other complex parts, and can complete drilling and milling. , Boring, expanding, reaming, rigid tapping and other process processing, suitable for the production of multi-variety, small and medium batch products, and can meet the processing of complex and high-precision parts. And a turntable that rotates along the horizontal axis can be installed on the workbench, which is what we often call the fourth rotation axis, so as to meet the processing requirements of special parts and the processing of helical parts. The vertical machining center is easy to install, easy to operate, easy to observe the processing situation, and easier to debug the program, so it is widely used.

However, this type of machine is limited by the height of the column and the tool changer, so it cannot process parts that are too high. When processing a cavity or a concave surface, chips are not easy to discharge, and in severe cases, the tool will be damaged and the machined surface will be damaged. , affecting the smooth progress of processing, it can be solved by installing an automatic chip conveyor and an oil cooler.
