The vertical machining center is a kind of sheet metal fabrication Large Japan Mill Machine Enclosure that provides molds and shell parts. When completing drilling, milling, boring and other processing processes, but its high price, and processing consumption is much higher than traditional manually operated machine tools, so the need for machining centers can be significantly reduced with single-piece processing. Therefore, the design of a machining center has a deep relationship with its machining efficiency and quality. How to make the design of vertical machining centers more standardized?
1: Higher static and dynamic demeanor
The price of vertical machining technology centers is high, and the loss during processing is much higher than that of traditional machine tools. This requires machine tools to significantly shorten the processing time. Regarding this problem, there are currently two ways to go. One is that the change in the development model of tool materials has greatly improved the cutting speed and doubled the cutting time; the other is through research and use of automatic tool changing systems to achieve the effect of rapid tool change and fast clamping. The adoption of these important measures has greatly improved the company’s production efficiency, allowing machine tool owners to obtain good economic and environmental benefits.
2: Better static stiffness
For a machining center, the structural stiffness of its components such as bed, worktable, spindle box, guide rail, etc. is closely related to the accuracy of the machine tool, so these factors require the machine tool to have relatively high static stiffness. In DH2F CNC Milling+EDM+Slow Wire Plastic Mold Inserts, there will be inevitable vibration, which will affect the processing accuracy and surface quality, also reduce the tool life, and have a significant impact on production efficiency. The machining center works continuously for a long time, and the vibration reduction during processing cannot be eliminated through human intervention and adjustment. Therefore, the dynamic stiffness of the machine tool also needs to be improved.
3: Smaller thermal deformation.
When the cutting machine is executed, without exception, it will generate heat, which will affect the anti-machine and machine tools, causing the components to produce varying degrees of thermal deformation, which will affect the accuracy of the processed products. How to affect the heat dissipation problem caused by the processing products is a slow decline in accuracy that has to be considered. At present, what we can do to improve the structure of the machine is that the thermal deformation of the machine lacks deformation in the direction we can control. For example. Using a double-column frame structure, the horizontal machining center column is symmetrical in the translational lifting axis direction, and thermal deformation of the horizontal machining center column can also be compensated by correcting the coordinates to reduce heat generation and separate the extrusion host from the heat source as much as possible.
4: The friction between moving parts is small and the gap in the transmission control system is eliminated.
The movement of the machine tool working platform is measured in small units of pulse equivalent. When performing tool or other slow-speed operations, the workbench is required to respond accurately to instructions issued by the CNC system, which is related to the friction of moving parts.
5: Long life, good accuracy retention
For the development of vertical machining technology centers, having its own perfect lubrication management system design is a great guarantee for the life of the machine tool. Therefore, it should be used when selecting machine tool guide rails, spindle components, screw rods, etc. The relatively wear-resistant materials enable the enterprise’s processing service center to maintain good accuracy for a long time.
6: Humanized design
In order to save time on clamping and changing tools, machining centers usually use multi-tool holders and Wire Cutting And CNC Turning Of Iron Castings, so that more problems can be solved with one clamping. Therefore, during the tool clamping and tool changing processes, manual intervention is minimized to make the human-computer interaction interface cleaner and tidier. The improvement of interlocking capabilities with machine tools can also effectively reduce the occurrence of accidents. At the same time, the setting of emergency parking devices can effectively avoid accidents, and all operations are concentrated on one panel, which is more conducive to operation.
