Factors affecting the price of CNC engraving machine
As we all know, the configuration of various engraving machines produced and sold by different CNC engraving machine manufacturers is very different, and the price of CNC engraving machine is also very different, so what factors will affect the price of CNC engraving machine? Here are five points for your attention:
1. Is the structure of engraving machine reasonable?
According to the structure, carving machine can be divided into column type and gantry type, while gantry type can also be divided into fixed gantry type and mobile gantry type, in which the rigidity of column type and fixed gantry carving machine is much better. According to the material, it can be divided into aluminum alloy, steel plate, cast iron and other materials. Its weight is increased in turn, and its rigidity is also increased in turn. As long as steel is not milled, wood, jade, copper, aluminum and other materials are carved, or soft metals such as copper and aluminum are milled in light weight, the aluminum alloy frame can fully meet the requirements.
In addition, the motion structure is also very important, whether it is ball screw or T-shaped screw, circular rail or square rail. If it is circular rail, it depends on whether it is linear bearing or self-lubricating bearing, and the screw does not need to use ball screw, which depends on whether it is domestic or imported. The approximate price is such self-lubricating bearing circular rail = twice the price of domestic linear bearing circular rail, domestic square rail = twice the price of self-lubricating shaft Price of bearing round rail, unit production square rail = 2 times of domestic square rail price, daily production square rail = 2 times of unit production square rail price; unit production ball screw price = 2-3 times of domestic ball screw price.
2. Is the electrical performance of the system stable?
The electrical performance of the system mainly depends on the anti-interference ability of the electric control part. Generally, the electric control is divided into Mach3 control and Viagra card control. Relatively speaking, the performance of Viagra card is very stable, but the USB version of Mach card is also very stable, and the carving deformation often seen is mostly controlled by the parallel port Mach3. The performance of the parallel port Mach3 is the most unstable, and it may be OK to change a computer, maybe In addition, the wiring of the electric cabinet is reasonable and the shielding is well done, which is also a necessary condition for anti-interference. The simple test is that if the stepping motor slightly moves at the moment of power on, it is not well done in anti-interference.
3. Does the effective travel meet the demand?
It depends on the length, width and height of the largest piece you need to carve, but don't go for a long journey, just enough.
4. Is the performance of the spindle motor good?
If you are making goods, then you must use water-cooled spindle. If you do more work, you'd better use 4-bearing water-cooled spindle, otherwise the service life is relatively low.
5. Is the carving speed of the carving machine fast?
Speed often determines the efficiency of the work forming. Generally, on the premise that the carving effect can meet the requirements, the faster the carving speed is, the better. Speed is not simply linked to F value, but depends on the acceleration of motor and the acceleration value can be set up. The actual carving speed can be closer to F value. The starting and ending of running line is influenced by acceleration, the middle section is F value, the lower the F value is, the better the carving quality is. The higher the acceleration value, the more precise the transition section is, the premise is that the machine is strong enough, and the stepping motor and driver are awesome enough. 。 If the complexity of the set fine engraving code view case is between 100000 and 300000 lines, it will not be slow after two hours.
