In addition to the difference in form, there are some structural differences between the horizontal machining center and the vertical machining center.
The selection of the type of machining center needs to consider factors such as the processing object, processing technology, processing range and equipment price, 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 the circumference, such as box and shell parts, etc. Choose a horizontal machining center; the position accuracy of the processed parts is required to be high, and a high-precision horizontal machining center should be used; when the parts need to complete multi-face machining in one clamping, you can choose a vertical-horizontal compound five-sided machining center. 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, the production efficiency, processing technology requirements and equipment funds should be considered when selecting the model. The selection should be measured by cost performance. The rationality of the type scheme.
The horizontal headstock is slidably connected to the movable column by a vertical drive screw fixed on the movable column, and is driven by the vertical drive screw to slide along the Y axis. The fixed column is equipped with a vertical headstock. The vertical drive screw fixed on the fixed column is slidably connected with the fixed column, and the vertical drive screw drives the Y axis to slide. The vertical machining center machine tool and the horizontal machining center machine tool are integrated, sharing the upper and lower working tables , Reduce the floor area, reduce the processing auxiliary time, and improve the work efficiency.
After the workpiece is clamped on the machining center once, the digital control system can control the machine tool to automatically select and change tools according to different processing procedures, automatically change the spindle speed, feed speed, and the motion path of the tool relative to the workpiece and other auxiliary functions, in turn Complete multi-process processing on multiple surfaces of the workpiece. And there are a variety of tool change or tool selection functions, so that the production efficiency is greatly improved.
Due to the concentration of processes and automatic tool change, the machining center reduces the time of workpiece clamping, measurement and machine tool adjustment, so that the cutting time of the machine tool reaches about 80% of the machine start time (normal machine tool is only 15-20%); at the same time; 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 small and medium batch production with complicated parts, high precision requirements, and frequent product replacement.
Compared with the vertical machining center, the horizontal machining center has a complicated structure, a large area, and a higher price. In addition, the horizontal machining center is inconvenient to observe 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.
