1. Before editing and inputting the workpiece program, the workpiece processing and machining program should be analyzed and programmed first, if the machining program of the workpiece is long or complicated. Do not program on a CNC machine, but use a programming machine or computer programming, and then back up to the CNC system of the CNC machine through a floppy disk or communication interface. This can avoid increasing the auxiliary time of machining when the machine is occupied.
2. Generally, the main power supply is turned on first, so that the CNC machine tool has the booting condition. The CNC system with the key button and the machine tool are powered on at the same time. The CRT of the CNC machine tool system displays the information, and at the same time checks the hydraulic pressure, pneumatics and each of the machine tools. Connection status of the intake and exit axes and other auxiliary equipment.
3. The fixed reference point machine establishes the movement reference of each coordinate of the machine before machining. For machine tools that increase the control system, this step should be performed first.
4. The input of the machining program is called according to the medium (tape, disk) of the program. It can be input by the tape drive, programming machine or serial port. If it is a simple program, it can be directly input on the CNC control panel by keyboard, or input by segment in MDI mode. Remote processing. Before processing, you must also input the butt origin, tool parameters, offset, and various compensation values ​​in the gamma program.
5. If the program edited by the program needs to be modified, the work mode selection switch should be placed in the edit position. Use Edit Jian to add, delete, and change.
6. The inspection and debugging of the program first locks the machine and only runs the system. This step is to check the program, if there is an error, you need to re-edit.
7. Installation and alignment of the workpiece The installation of the lower part to be processed is corrected and a reference is established. The method uses manual incremental movement, continuous movement or hand wheel to move the machine. Set the starting point to the beginning of the program and benchmark the good tool.
8. Starting the coordinate axis for continuous processing Continuous processing is generally done by using a program in the memory. The feed speed in CNC machining can be adjusted by the feedrate override switch. During the machining, the feed hold button can be pressed, the feed motion can be paused to observe the machining condition or manual measurement. Press the cycle start button again to resume the processing. The correct procedure for the bowl guarantee is correct. You should review it again before adding it. In the case of milling, for the flat curve, the pencil can be used instead of the tool to draw the contour of the workpiece on the paper. This is more intuitive. 'If the system has a tool path, the simulation function can be used to check the correctness of the program.
9. After the shutdown is completed, before turning off the power, pay attention to check the status of the CNC machine and the position of each part of the machine. Turn off the machine's power, then turn off the system's power, and finally turn off the main power.
KNBL1-32 Residual Current Circuit Breaker With Over Load Protection
KNBL1-32 TWO FUNCTION : MCB AND RCCB FUNCTIONS
leakage breaker is suitable for the leakage protection of the line of AC 50/60Hz, rated voltage single phase 240V, rated current up to 63A. When there is human electricity shock or if the leakage current of the line exceeds the prescribed value, it will automatically cut off the power within 0.1s to protect human safety and prevent the accident due to the current leakage.
leakage breaker can protect against overload and short-circuit. It can be used to protect the line from being overloaded and short-circuited as wellas infrequent changeover of the line in normal situation. It complies with standard of IEC/EN61009-1 and GB16917.1.
