Numerical control lathe knife accident prevention measures
Numerical control lathe colliding of accident prevention measures release date: 2019 - 11 - 30 author: click: for CNC lathe colliding accidents, such as not complying with lathe safety operation rules in personal injury or equipment accidents will happen. In machining process, because most of them are configured with the security door, close the safety door process requirement, the operator does not directly operation of machine tool, so personal injury probability is very small, but the equipment accident probability is much bigger than other machining, because ordinary machine tool by the operator with his experience in operating manual machine tool for processing. By machining process automatic control machine tool CNC lathe processing, not directly under the control of the people, but is controlled by the program. Technical personnel in the operation of the machine tool tend to program is wrong, wrong and correction, coordinate system or the cutting tool compensation into error, the carelessness of the operation of the machine tool are colliding accidents. If there is a bump in the process of nc lathe using knife phenomenon, not only can bring large pressure in my heart, to the operator can also cause economic losses. So how to avoid and prevent? As a result of the numerical control equipment is expensive, difficult to repair, and machining parts of high precision, high efficiency, high automation is mainly rely on the accuracy of machine tools to ensure that, in the event of equipment accident, precision machine tools will be severely reduced. In fact, the colliding accidents have rules to follow, because of the nc machining using software to lock, when in the simulation process, when the run button in the simulation interface is not intuitive to see whether machine tool has been locked. Simulation is often not the knife again, if there is no lock machine tool operation, easy to occur through. So before the simulation processing should confirm the machine is locked to the running interface. Forget to switch off air when processing. Due to the process simulation, in order to save time will often empty switch operation. Not to go back to the reference point after empty running simulation. CNC lathe is locked in the calibration program without moving, and the cutting tool relative workpiece machining in the simulation run, Absolute and relative coordinates in the change) , then the coordinates of the do not tally with the actual location, must use the method of return reference point, ensure the mechanical zero point coordinates are in accordance with absolute and relative coordinates. When small CNC lathe overtravel, should hold the overtravel remove button, using hand or hand in the opposite direction, which can be eliminated. But if the direction of the lift opposite, will damage to machine tool. Because when press the distance to lift, machine tool does not make sense to distance protection, distance protection of travel switch is at the end of the trip. Could lead to a table at this time continue to move in the direction of overtravel, pull the bad screw, machine tool damage specified runtime, often starts down the cursor location. Used for lathe, need to call value cutter knife, if there is no call tool, run the program section of the tool may not have to tool, likely the colliding accidents caused by different cutting tools. On the processing center, CNC milling machine, of course, want to call first coordinate system, such as G54 and the length of the cutter compensation value. Because the length of each knife compensation values are not same, if not call may also be caused by knife. So we should grasp the small CNC lathe programming skills, use various methods to test the program, coordinate system and the length of the cutting tool radius compensation, compensation set up correctly, be careful in the process of operation, to avoid unnecessary mistakes, can effectively avoid colliding phenomenon, better protection for CNC lathe.
