The maintenance of the cnc horizontal machining center body mainly refers to the maintenance of the mechanical parts of the machine tool. Since the mechanical parts are in the process of motion friction, maintenance is very important to ensure the accuracy of the CNC machining center, such as the cooling and lubrication of the headstock, gear pairs, guide rails Clearance adjustment and lubrication of pair and screw nut pair, bearing preload, adjustment of pressure and flow of hydraulic and pneumatic devices, etc. Because of the difference in function, structure and system of cnc horizontal machining center, its maintenance content and rules also have their own characteristics, which should be based on the model system of cnc horizontal machining center.

Many users may not pay special attention to the operation points when using cnc horizontal machining center, and some detailed problems are often easily ignored.
1. Ensure that the machining content of the workpiece is completed within the stroke range of the spindle of the cnc horizontal machining center.
2. Try to complete all the processing content in one clamping. When it is necessary to replace the clamping point, special attention should be paid not to damage the positioning accuracy due to the replacement of the clamping point, and explain it in the process document if necessary. . The contact between the bottom surface of the fixture and the worktable, the flatness of the bottom surface of the fixture must be within 0.01-0.02mm, and the surface roughness is not greater than Ra3.2um.
3. The cnc horizontal machining center fixture should have as few components as possible and high rigidity.
4. In order to simplify the positioning and installation, each positioning surface of the fixture should have the coordinate size relative to the processing origin.
5. For a machining center with an interactive worktable, the fixture design must prevent spatial interference between the fixture and the machine due to the movement of the worktable, lifting, lowering, and rotation.
6. The fixture should be opened as much as possible, the spatial position of the clamping element can be lower or lower, and the installation fixture should not interfere with the tool path of the working step.
7. The cnc horizontal machining center 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 very short, the loading and unloading of the supporting fixtures cannot take up too much time.
8. In order to ensure that the installation orientation of the parts is consistent with the direction of the workpiece coordinate system and machine tool coordinate system selected in the programming, and directional installation.
cnc 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 processing procedures, and 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 function to complete the processing of multiple processes on multiple surfaces of the workpiece in turn. And there are a variety of tool change or tool selection functions, so that the production efficiency is greatly improved.
