Horizontal machining center and vertical machining center are not just the difference in shape

In addition to the shape difference between the horizontal machining center and the vertical machining center, there are also some structural differences.

　　The selection of machining center type needs to consider factors such as the processing object, processing technology, processing scale and equipment price, etc., and proceed according to the selected part family (group). If your workpiece has the following characteristics, you should choose a horizontal machining center: machining parts with more than two sides or machining holes and faces arranged radially around, such as box and shell parts, etc. Horizontal machining centers should be selected; high-precision horizontal machining centers should be used for parts to be machined with higher azimuth accuracy requirements; when parts need to be processed on multiple sides in one clamping, a vertical-horizontal compound five-sided machining center can be selected. Of course, the above points are not true. On the one hand, the machining center is developing in the direction of compounding. On the other hand, when selecting the model, it is necessary to comprehensively consider factors such as output power, processing technology requirements, and equipment funds. The rationality of the type scheme.

The horizontal headstock is slidably connected to the movable column by a straight drive screw fixed on the movable column, and slides along the Y-axis direction by the straight drive screw. The fixed column is equipped with a vertical headstock. The straight drive screw fixed on the fixed column is slidingly connected with the fixed column, and the Y-axis direction slide is driven by the straight drive screw, the vertical machining center machine tool and the horizontal machining center machine tool are integrated, sharing the upper and lower working tables , It reduces the area occupied, reduces the processing auxiliary time, and improves the working power.

After the workpiece is clamped on the machining center once, the digital control system can control the machine tool to automatically select and replace tools according to different processing procedures, and automatically change the spindle speed, feed rate, and the motion path of the tool relative to the workpiece and other auxiliary functions, in turn Finish multi-process processing on multiple faces of the workpiece. And there are a variety of tool change or tool selection functions, so that the output power is greatly improved.

Due to the concentration of working procedures and automatic tool change, the machining center reduces the time for workpiece clamping, measurement and machine tool adjustment, so that the cutting time of the machine tool reaches about 80% of the machine start time (only 15-20% for ordinary machine tools); It also reduces the work piece turnover, handling and storage time between processes, shortens the production cycle, and has obvious economic effects. The machining center is suitable for the production of small and medium batches with complex shapes, high precision requirements, and frequent product replacements.

Compared with the vertical machining center, the horizontal machining center has a complicated structure, a large area, and a higher price. The horizontal machining center is inconvenient to investigate during processing, and it is inconvenient to clamp and measure parts, but it is inconvenient for chip removal during processing. Easy and beneficial to processing.
