Tell you the operating points of the horizontal machining center:
1. Ensure that the machining contents of the workpiece are completed within the stroke range of the spindle.
2. Try to complete all the processing contents in one setup. When it is necessary to replace the clamping point, special care must be taken not to damage the positioning accuracy due to the replacement of the clamping point, if necessary in the process documentation. The bottom surface of the fixture is in contact with the workbench, and the flatness of the bottom surface of the fixture must be within 0.01-0.02 mm, and the surface roughness is not greater than Ra3.2um.
3. The fixture should have as few components as possible and high stiffness.
4. In order to simplify positioning and safety, each positioning surface of the fixture should have an accurate coordinate size relative to the machining origin.
5. For machining centers with interactive worktables, the fixture design must prevent space interference between the fixture and the machine tool due to movement, lifting, lowering, and rotation of the workbench.
6. The fixture should be as open as possible. The position of the clamping element can be low or low, and the installation fixture cannot interfere with the tool path of the step.
7. It can be disassembled in a short time and changed into a fixture suitable for new workpieces. Since the auxiliary time of the machining center has been compressed to a short extent, the loading and unloading of the supporting jig cannot take up too much time.
8. In order to ensure the consistency of the part mounting orientation and the selected workpiece coordinate system and machine coordinate system in the programming, and orientation installation.
The working principle of the horizontal machining center:
After the workpiece is clamped once on the machining center, the digital control system can control the machine tool to automatically select and replace the tool according to different machining processes, automatically change the spindle speed of the machine tool, the feed speed and the movement track of the tool relative to the workpiece and other auxiliary functions. The processing of multiple processes on multiple faces of the workpiece is completed. And there are a variety of tool change or knife selection functions, which greatly improve production efficiency.
Due to the concentration of the process and the automatic tool change, the machining center reduces the time for clamping, measuring and machine adjustment of the workpiece, 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 workpiece 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-sized batch production with complex parts, high precision requirements and frequent product replacement.
Compared with the vertical machining center, the  has a complicated structure, a large floor space, and a high price. Moreover, the horizontal machining center is inconvenient to observe during processing, and the parts are not easy to be clamped and measured, but the chip removal during processing. Easy, good for processing.
