Numerical control lathe nine basic steps The nc lathe turning center processing center Shandong numerical control lathe numerical control lathe numerical control lathe manufacturer price 1. The part of the program to edit and input processing before should first analysis and establishment of artifacts and the kernel technology and processing procedures, if the workpiece processing program is long or complicated. Don't in nc lathe programming, and adopts programming machine or computer programming, and then through a floppy disk or backup communication interface to numerical control lathe numerical control system. This can avoid take up machine, increase the auxiliary time of processing. 2. The boot General is to open the main power supply first, so that CNC lathe with the boot conditions, starting with a key button and the lathe numerical control system at the same time to electricity, information is shown on the CRT of nc lathe system, at the same time check hydraulic lathe, pneumatic, each into the clam shaft connection state and other auxiliary equipment. 3. The fixed reference point lathe processing before establishing lathe coordinate shift
