how to classify different cnc router?
what are the different type of cnc router classify! follows information let to know more cnc router technique information!
most these type of cnc router Spindle is not big which are used roundness rail for cutting and engraver acrylic,wood,plastic.and price is cheap.)
these type of cnc router has very big spindle to engraver strong stone,and also has water channel for cooling knife when the machine working.
if you want to be fast speed and plus automatic adsorption function for working everday on wood, so you choose this type of machine, this type of machine is very expensive including all optional function.
these machine all other specification same with other cnc router,only one differece is the spindle, the machine table has more one spindle working togerther, so it has upgrade the machine speed.
is a metal sculpture on a graphic capable machines. General mechanical engraving, laser engraving, electrochemical carving. Mechanical engraving machine, laser engraving machine we should be more familiar with. So, here I introduce a "multi-functional high-speed electronic metal engraving machine," which is a kind of electrochemical electric engraving machine engraving machine in addition to a metal engraving machine functions, it also has a metal marking machine, gilding machine, electroforming machine, metal marking machine, metal color machine, electroplating machine, copper (steel) plate painting machines, electrophoresis machine, brush plating machines, pile of gold, electromechanical polishing machine and aluminum and aluminum oxide and other coloring All functions of the machine. (this type of machine has good driver and good spindle with water channel on the machine)
has very big and strong power and Resolution, and also working no any noise.
(different between step motor cnc router and servo cnc router):
( 1 ) Different frequency torque characteristics .
For torque , the need to add that there is no holding torque servo itself , but there is holding torque stepper motor . The difference is that the so-called stationary servo motor is actually a balancing process , the motor does not really stop at the specified location ( so AC servo reproducibility feedback to be given to the resolution of 3-5 times , and step reproducibility into the motor can be higher than the resolution ) .
( 2 ) Control of different accuracy.
Obviously , the landlord does not know stepper motor drive has " broken down " concept. Two-phase stepper motor step angle is 1.8 degrees right, but now drives 64 segments are also common. Note that this time, the motor is 200 * 64 = 12800 pulses revolution . The common market AC servo encoder but a 2048 or 2500 lines. Of course , there are 17 motor encoder , however , stepper drives also have 256 segments . From the resolution , the AC servo or higher, but far from the landlord written so exaggerated. And, since it is said to control the precision , then used the servo people should know that the servo dynamic reproducibility is how many times the resolution . On conventional designs, the selection, should reproducibility index multiplied by 5 as the servo feedback resolution. In this way, the control precision servo servo really better than okay ?
( 3 ) Different overload .
This has nothing to say , but for the moment the waste argument , or a little advice . Many stepper drives provide a semi- streaming capabilities , without the need for full torque output , they can reduce the current, reducing torque.
( 4 ) Different operating performance.
Lost step stepper motor is indeed a fatal flaw , but it can not consider the servo deceleration curve it? You really try to give a step signal , the motor will be much jitter. But go shake shake , will eventually stop in the correct position , it is indeed stronger than stepping . If you are positioning control , the jitter does not matter if it is process control , who would be so used ?
