Numerical control lathe knife disturbance of preparedness

about nc lathe colliding of issue, if you don't abide by the lathe will attack the personal issue or equipment safety regulations. In machining process, due to the greatly are all with the security door, processing requirements closed door, the operator does not directly operation of machine tool, and the personal issue risk is small, but the chance of equipment trouble attack is much bigger than other machining, because the general machine tools is after the operator experience with its own operating manual machine tool for processing; Numerical control lathe active manipulation of the machine tool for processing after processing procedure, not direct manipulation, but by the manipulation of 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, operation of the machine tools will be formed through carelessness. In the process of nc lathe using if attacks hit knife phenomenon, not only can bring great pressure in the heart to the operator, also can form must be economic losses. So how to prevent and guard against? As a result of the numerical control equipment is expensive, difficult to repair, and processing parts of high precision, high power, high active first depend on, to ensure the precision of machine tool equipment, once the attack precision of machine tools will be serious decline. In fact, the outbreak of the colliding of the issue have rules to follow, because at the beginning of the nc machining for software to lock, by imitating the processing, when press the active button in imitating operation interface cannot visually see whether the machine has been locked. Imitate is often not the knife again, if the machine did not lock operation, easy to attack hit knife. Before the imitation process should be to confirm the machine tool operation interface is locked. Processing forget closed air switch. Due to the application to imitate, in order to save time will often switch on idle running. After idling imitate not to go back to the reference point. Numerical control lathe is locked in the calibration program without moving, and the cutting tool relative workpiece machining imitating operation ( Must coordinate and changes in relative coordinates) , then the coordinates of the does not accord with the actual bearing, must by return reference point, to ensure that the mechanical zero point coordinates are in accordance with certain and relative coordinates. When CNC lathe overtravel, should hold the distance release button, using hand or hand to move in the opposite direction, which can eliminate. But if from the direction opposite, will attack damage of nc machine tools. Because when the press distance from super routine maintenance will not effect of machine and routine maintenance of travel switch has been the end of the trip. There are may lead to work station to continue moving in the direction of distance, after all the bad screw, forming machine tool damage specified line operation, often starts down to perform the cursor location. Demand calls for lathe cutter knife used in partial value, if did not call the cutting tool, operation procedures section of cutting tools, tool may not be wanted is perhaps different cutting tool to the colliding of the issue. In processing center, CNC milling machine, of course, must call first coordinate system, such as G54 and the length of the cutter compensation value. Due to the length of each knife compensation values are not the same, if not call also have may form a knife. So we should grasp the nc lathe programming skills, using various methods to verify 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 prevent unnecessary mistakes, can be useful to prevent collision phenomenon of attack, better maintenance of CNC lathe.
