The Main Axis Of The Horizontal Machining Center Is Set Horizontally

The main axis of the horizontal machining center is set horizontally. The general horizontal machining center has three to five coordinate axes, often equipped with a rotary axis (or rotary workpiece table), the spindle speed is within 10 ~ 10000r / min, the minimum resolution is generally lμm, and the positioning accuracy is 10μm— 20μm. The tool magazine capacity of horizontal machining centers is generally large, and some tool magazines can store hundreds of tools. The structure of the horizontal machining center is more complicated than that of the vertical machining center, with a larger volume and area, and a higher price. Horizontal machining center is more suitable for processing box parts. As long as it is clamped on the rotary table at a time, the four sides of the box (except the top and bottom surfaces) can be processed by milling, boring, drilling and tapping. In particular, some holes and cavities on the box parts have position tolerance requirements (such as the parallelism between the hole system, the perpendicularity of the hole and the end surface, the perpendicularity of the end surface and the bottom surface, etc.), as well as the holes and cavity If it has strict dimensional accuracy requirements with the reference surface (bottom surface), it is easy to be guaranteed by one-time clamping processing on the horizontal machining center, which is suitable for the processing of batch workpieces. When debugging a horizontal machining center program, it is not as intuitive and easy to observe as a vertical machining center. It is also inconvenient for inspection and measurement of workpieces, and the debugging time for machining procedures of complex parts is several times that of normal processing, so the more workpieces processed On average, the less time each piece of machine tool takes up, it is therefore cost-effective to use a horizontal machining center for batch processing. However, it can achieve precision and quality requirements that are difficult to achieve with ordinary equipment, so some precision requirements are high, and other equipment cannot meet its precision requirements. Especially for some spatial curved surfaces and complex shapes, even single-piece production can be considered. Processing on a horizontal machining center. It can be seen that the machining center is not only an efficient and high-quality automated production equipment, but also an equipment to overcome technological difficulties.

The coordinate system of horizontal machining center is different from the coordinate system of vertical machining center, that is, the three axes X, Y and Z in space. Moreover, the cooling condition of the horizontal machining center is not as good as that of the vertical type, especially for deep hole boring, milling, drilling, etc., the coolant is difficult to reach the depth of the cutting, so the speed and feed of the machine tool must be reduced and the production efficiency is reduced . Compared with the vertical machining center, the horizontal machining center has many functions. Workpieces that cannot be processed on the vertical machining center can generally be processed on the horizontal machining center. In addition, some of the rotary worktables of the horizontal machining center are numerically controlled and some are indexed. The workpiece can be processed in multiple stations by clamping at one time. Generally speaking, the horizontal machining center has its advantages and disadvantages.
