? A lathe with a diameter of 4.5m is reformed by using the x and z axes linked with the spindle CNC machining method, and then according to the design of the folding reel, the CNC machining of the rope groove of the folding reel is started.
Here is introduced x, z two axes with the spindle linkage CNC machining method, the principle is shown in the following figure. The principle is basically the same as the principle of Z-axis CNC machining with the spindle, the difference is that the system adds the X-axis motor and the driver to the tool holder and the tool to realize the X-direction automatic feed movement, so as to realize the X-direction automatic feed function in the machining process.
During processing, the reel rotates under the drive of the spindle motor of the original machine tool. The CNC system obtains the position of the reel on the circumference through the spindle encoder and the spindle zero switch according to the corresponding CNC program. At the same time, the z axis and x axis motor are driven to realize the differential linkage of the x and z axes with the spindle angular displacement, and the CNC machining of the folding reel rope groove can be realized.
This method has a high degree of automation, can realize the X-direction automatic feed and rewind control, no manual control is needed, and realize the automatic CNC machining of the folding line groove. The equipment transformation is simple and the cost is low.
