The safety operation rules of the machining center must be followed: before work, you should wear protective equipment and tie your cuffs. Scarves, gloves, ties, and aprons are not allowed. Female workers should wear braids in hats. Before starting the machine, check whether the tool compensation, machine zero point, workpiece zero point, etc. are correct. The relative position of each button should meet the operating requirements. Carefully compile and input CNC programs. It is necessary to check the operation status of the protection, insurance, signal, position, mechanical transmission part, electrical, hydraulic, digital display and other systems on the equipment, and cutting can be performed under normal conditions. Before processing, the machine tool should be run for trial operation, and the operating conditions of lubrication, mechanical, electrical, hydraulic, digital display and other systems should be checked. Cutting processing can be performed under normal conditions. After the machine tool enters the processing operation according to the program, the operator is not allowed to touch the moving workpiece, tool and transmission part, and it is forbidden to transfer or take tools and other items across the rotating part of the machine tool. When the CNC machining center adjusts the machine tool, clamps the workpiece and tools, and wipes the machine tool, it must be stopped, and tools or other items must not be placed on electrical appliances, operation cabinets and protective covers. It is not allowed to remove iron filings directly by hand. Special tools should be used to clean it. If abnormal conditions and alarm signals are found, stop immediately. Please check with relevant personnel. It is not allowed to leave the work position when the machine tool is running. , put the worktable in the middle position, the tool bar is retracted, it must be stopped, and the power supply of the host machine is cut off.
CNC lathe machining center start-up processing: direct numerical control (DNC) operation, before DNC numerical control processing, the workpiece must be clamped, the zero position is set, and the parameters are set. Open the processing program to be transmitted in the computer to check, then let the computer enter the DNC state, and input the correct file name of the processing program. Press the TAPE key and the program start key on the machine tool, then the machine tool controller will flash the word LSK. Press the Enter keyboard on the computer to perform DNC data transfer processing. When executing each program, it must be carefully checked. Whether the tool specified in the programming guide is the tool specified in the programming guide. When starting processing, the feed speed should be adjusted to the minimum, single block execution, rapid positioning, tool drop, and tool feed must be concentrated. The hand should be placed on the stop button and stop immediately if there is a problem, pay attention to observe the direction of the tool movement to ensure safe feeding, and then slowly increase the feed speed to an appropriate level. It should not be too far away from the control panel. If there is any abnormal phenomenon, it should be stopped and checked in time. After roughing, pull the table again to make sure that the workpiece is not loose. If there is a side, it must be re-calibrated and touched, and the processing parameters should be continuously optimized during the processing to achieve the best processing effect. Because this process is a key process, after the workpiece is processed , It should be measured whether the main dimension values are consistent with the drawing requirements. If there is a problem, immediately notify the team leader or programmer to check and solve it. After passing the self-inspection, it can be removed and must be sent to the inspector for special inspection.
Looking forward to your consultation if there is anything unclear
