Horizontal Machining Center Manufacturer: Introduces the operating points and working principle of the horizontal machining center
Release Time:
2021-05-11
When using horizontal machining center Many users may not pay special attention to the key points of operation, and some detailed issues are often overlooked:
1. Ensure that all processing of the workpiece is completed within the travel range of the spindle.
2. Try to complete all machining operations with one clamping. When it is necessary to change the clamping point, special attention should be paid to avoid damaging the positioning accuracy due to the change of the clamping point, and make a statement in the process document if necessary. In order to make the bottom surface of the fixture contact with the worktable, the flatness of the bottom surface of the fixture must be within 0.01-0.02mm, and the surface roughness should not be greater than Ra3.2um.
3. The fixture should have as few parts as possible and high rigidity.
4. In order to simplify positioning, each positioning surface of the fixture should have coordinate size relative to the machining origin.
5. For machining centers with interactive worktables, the design of the fixture must prevent spatial interference between the fixture and the machine tool due to the movement, lifting, lowering, and rotation of the worktable.
6. The fixture should be as open as possible, the spatial position of the clamping element should be as small as possible, and the installation of the fixture should not interfere with the tool path of the work steps.
7. After a short period of disassembly, it can be replaced with a fixture suitable for the new workpiece. Because the auxiliary time of the machining center has been compressed to a very short time, the loading and unloading time of the support fixture will not be too much.
8. To ensure the consistency of the workpiece installation position with the workpiece coordinate system and machine tool coordinate system direction selected in programming and directional installation.
horizontal machining center Working principle:
Once the workpiece is clamped on the machining center, the numerical control system can control the machine tool to automatically select and change the tools, automatically change the spindle speed, feed speed and movement path relative to the tool according to different processing programs. Workpiece and other auxiliary functions, complete the multi-faceted processing of the workpiece in turn. And has a variety of tool change or tool change functions, greatly improving production efficiency.
Due to the centralized process and automatic tool change, the machining center reduces the time of workpiece clamping, measurement and machine tool adjustment, so the cutting time of the machine tool reaches about 80% of the machine tool starting time (normal machine tool is only 15-20%); At the same time; it also reduces the turnover, handling and storage time between workpieces and processes, shortens the production cycle, and has obvious economic effects. This machining center is suitable for small and medium batch production with complex parts, high precision requirements and frequent product changes.
