With the continuous improvement of social productivity, people's performance requirements and use requirements for production tools are also getting higher and higher. In the past, metal processing was mainly based on ordinary machine tools . The machining accuracy of the workpiece was closely related to the operator. However, with the popularity of CNC machine tools , the machining accuracy of the workpiece does not depend on people, but on CNC machine tools . Let's share our experience with imported CNC machining centers and domestic CNC machining centers.
My company is mainly engaged in the processing and production of axle components for automobiles, which belong to gold processing. The equipment used is mainly CNC lathes and CNC machining centers. Three-quarters are imported CNC machining centers, and one quarter is domestic CNC machining centers. Some people may ask why not use the domestic CNC machining center and use more imported CNC machining centers. In fact, the company has chosen to import more and less domestically. Although China's equipment industry has made great progress in recent years, there are still big gaps in the design, assembly and installation of equipment, equipment processing precision and after-sales service with foreign manufacturers.
First of all, the ladder diagram of the imported CNC machining center system is very detailed. For example, when the machine fails, there will be as much information as possible to indicate the location of the fault point, and some will also prompt you how to deal with the fault. If you are used to import CNC machining centers, you will feel uncomfortable using the CNC machining centers. On the same problem, if the cable of one axis is worn out and a short circuit is generated, the fault alarm prompt of the imported machining center will be clearly displayed. However, many CNC machining centers in China do not have any fault prompts, just Where is the alarm light flashing. The same fault problem, the imported CNC machining center can find the fault point and eliminate it according to the fault alarm prompt for a few minutes, but you don't need to work hard to find the fault point, it is difficult to eliminate the fault point.
Secondly, the imported CNC machining center has a certain gap in terms of line orientation and protection compared with the domestic CNC machining center. The imported CNC machining center is generally standardized and protected, and it is relatively reliable and safe. It is difficult to find that the line assigned to each axis will be worn out and cause an open circuit failure. However, the domestic CNC machining center is worn due to the wear of the lines of each axis. Short circuit is more common, and there is no regulation of the trace. You want to improve it. On the one hand, space is not allowed, on the other hand, it is difficult to replace the worn line.
Trace of each axis of XH716E CNC machining center
The above is the trace picture of each axis of the domestic model XH716E CNC machining center. It can be seen from the picture that the line does not have any protection, the line is often worn out, and the maintenance personnel can't just connect the broken line and then put a layer of snake skin to make it easy to use. It is difficult to improve it, only when the snakeskin tube is worn out and then the snake skin tube is replaced. A similar failure did not occur once in the imported CNC machining center.
In addition, the protection of the imported CNC machining center is also relatively good. It is difficult to see iron filings or coolant leakage on the periphery of the machine tool . The peripheral piping and circuit direction are also relatively standardized and user-friendly. . The domestic CNC machining center leaking iron coolant leakage coolant is a difficult problem. The peripheral pipelines and lines are in a mess. For many years, the above problems have always existed whether it is the domestic CNC machining center or the domestic CNC machining center.
Protection and peripheral pipeline diagram of XH716E CNC machining center
The above is a picture of the protection and peripheral pipeline diagram of the domestically produced model XH716E CNC machining center. It can be seen from the picture that the coolant and iron filings are everywhere, and the pipes are dragged to the ground in a mess.
The above is a bit of a dip in the use of imported machining centers and domestic CNC machining centers. I hope that some domestic equipment manufacturers will be inspired to make domestic equipment more developed and improved in terms of quality and operation.
