螺纹对刀方法(国外英文资料) For the high precision worm, we usually use two car knives, namely a rough lathe and a fine turning tool. After rough turning worm in CNC lathe tool change fine cars, often because of knife, make turning cannot continue, to limit the application of the numerical control lathe in the worm turning. In the past for a period of time, we in solving the problem of numerical control lathe finish turning worm of cutter has made some attempt to find a kind of effective method, is to configure FAUNC 0 tc system CK7815D nc lathe turning Archimedes worm (ZA) as an example are briefly introduced as follows. 1, the processing principle of The basic principle of the worm turning is the same as the threading of the thread, so on the CNC lathe, we can use the threading tool to cut the worm. In general, threading is the process of repeatedly cutting through the same path along the same path. When cutting thread on CNC lathe, to ensure that the turning of the lathe is not buckled, it is always used to start threading when the main shaft encoder sends a signal. So clamping at the same time, the same tool, machining parameters at the same time, the thread starting point is always a fixed point, the workpiece on the tool passes through the trajectory is a constant. It is important to note that the spindle speed cannot be changed from the screw to the fine car, otherwise the starting point of the thread will change, thus causing the confusion. In addition, on the CNC lathe, lathe tool is located along the axial offset parts, turning and turning the spiral along the axis direction of the corresponding parts will also shift. According to this principle, we can locate the starting point of the shaft of the part of the car to the side of the gearbox. 2, operation steps, (1) to determine the processing parameters according to the drawing of the parts: the lead (the number of PI x), the cut length, the spindle speed and the rotation. (2) to identify the specific processing equip
