MICRO DNC 3A is an equipment used for replace for the old transfer data by using computer. When using computer to transfer data to CNC machine, it will have some disadvantage: the connection will not stability, waste the acreage. Then MICRO DNC 3A device has improved these advantages to make the transfer data become more easier, faster and more convenient. Most older CNC machines have very small memory, which will make loading the program into memory often to use different small programs, or have the option to drip the program "DNC function" . The transmission of the program to the CNC machine is through the RS232 port on the CNC machine The traditional DNC solution uses a computer with specialized DNC software installed (such as CimcoEdit, DosteskDNC, ProDNC?) to stream the machining program to the CNC machine. This solution has some disadvantages as follows: - Placing a set of computers near the CNC machine occupies the workshop area. Power cord rs232 cable will be very troublesome for CNC machine work place - Manipulating the computer takes a lot of time and many stages (starting the computer, starting the software, installing, selecting ...). - Computers sometimes malfunction or are attacked by viruses, causing work interruptions, reducing productivity. With the above disadvantages of the traditional solution, we have researched to integrate the most necessary functions with the goal of compact product and optimized operation, in order to improve productivity and economy in the future. In the process of using CNC machines, the product DNCdevice ? The transmission program for CNC machines was born. MICRO DNC 3A can connect to a computer via wireless LAN (wifi) to control transmission, copy program between DNC DEVICE and computer MICRO DNC 3A has 4GB internal memory, has 2 USB 2.0 ports to read programs in USB stick transfer program into CNC machine memory transmit DNC drip program (works in TAPE mode) receive program or PC / PARAMETER from CNC machine Package includes 1 DNC 3A, 1 ADAPTER 12VDC, 1 RS232 cable DP9(female)-DP25(male) We have a long-term customer care regime, throughout the operation of the device. and can help you set up the device to work on cnc machines
