Many people think that the portable CNC cutting machine is outdated and the cutting accuracy is not as good as the gantry cutting machine. Is it really? How accurate is the portable CNC cutting machine? Is the accuracy of the portable CNC cutting machine really not as good as the gantry cutting machine? With these issues in mind, Mingcheng shares a story with you.


In the field of metal CNC cutting, the precision of CNC cutting is 0.1mm, and the cutting precision is 0.5mm. This is related to the CNC cutting method. Compared with traditional manual cutting, the accuracy is already high, but compared with laser cutting, this accuracy is far from enough. The main difference is the cutting method. Of course, in order to ensure the accuracy of the equipment, the laser cutting machine needs higher frame technology.


Is the accuracy of the portable CNC cutting machine lower than that of the gantry CNC cutting machine? The answer is no. In fact, there are differences in the accuracy of CNC cutting machines. The difference is caused by external factors or human operation factors.

The first is the tool factor. Everyone knows that the gantry CNC cutting machine itself is relatively large, and each machine has a fixed cutting tool, so the material placement is relatively stable. However, portable CNC cutting machines can usually work directly in various environments. More than half of customers directly support the steel plate on the flat ground and work on site. Due to the flatness of the plate, the accuracy of the portable CNC cutting machine is not as good as the gantry.


The second is human factors. Gantry-type CNC cutting machines are generally full-page or large-slab operations.


Place the steel plate on the tool. Except for manual driving, forklifts or external tools, there is usually no displacement caused by human operation. The same is true for the cutting machine itself. Longmen will not change its trajectory due to external forces. However, due to the light weight of the portable, it may be affected by external factors (such as physical contact and wire harness pulling) in the normal operation of workers. The movement or vibration of the machine changes the accuracy of the cut parts.

The above two reasons lead to insufficient cutting accuracy of the portable CNC cutting machine in some cases, leading to the misunderstanding that its accuracy is not as good as the gantry accuracy. In fact, as long as the above external factors interfere with customer service, the cutting accuracy of the portable CNC cutting machine will not be worse than that of the gantry.


In the entire metal processing industry, various equipment has its suitable uses. The company will comprehensively select the appropriate products according to its own needs, environmental and economic factors, and the best that suits itself is the best.
