The working principle is as follows:
(1) starting a machine tool, determining a machining mode of the machine tool, clamping a blank, measuring a size to be machined related to the blank by using a precision measuring instrument, determining machining allowance, starting machining a workpiece to be machined, and performing finish machining circulation until the precision requirement is met;
(2) when the single-tool machining mode is selected, the single-tool machining modes are three, the most suitable turning tool can be opened among the three turning tools according to the contour of the part and the machining precision requirement, the workpiece to be machined is machined, and different turning tools can be selected for machining according to the requirements during rough machining and finish machining;
(3) when a multi-cutter machining mode is selected, four multi-cutter machining modes are available, three-cutter machining or two-cutter machining can be selected according to the contour of a part and the machining precision requirement, three different modes are selected for the two-cutter machining, in addition, only three-cutter machining or two-cutter machining can be used in rough machining and finish machining, three-cutter machining or two-cutter quick machining can be selected in rough machining, and single-cutter machining can be adopted in finish machining, so that the machining requirements of high efficiency and high precision are met.
According to the processing method of the multi-cutter efficient synchronous dynamic balance turning processing machine tool, when a workpiece is processed, the cylinder 30110 is in an extending state under the default condition, namely the small bevel gear 30302 is meshed with the large bevel gear 30301, the machine tool is in a working mode of simultaneously processing three cutters, and because the three cutters 30102 are installed at intervals of 120 degrees, acting forces of the three cutters 30102 on the workpiece to be processed are mutually offset when the workpiece to be processed is processed, so that the stress deformation of the workpiece to be processed is reduced, and the processing precision is improved; and because the servo motor II 30303 drives the small straight gear 30304 to drive the large bevel gear 30301, and then the large bevel gear further drives the small bevel gear 30302 to rotate at the same time, the three turning tools 30102 can synchronously perform radial feed motion, so that synchronous cutting processing of the workpiece to be processed is realized.
When the machine tool is started for processing, firstly, a motor 30105 is started to adjust the turning tool 30102 to a proper position, and then a servo motor I611 is started to work to move the workbench module 3 to a specific processing area to wait for processing; the electric spindle 402 is started to rotate the workpiece to be processed at a set rotation speed, and the servo motor 30303 is started to enable the turning tool 30102 in a working state to move in the axial direction and the radial direction of the workpiece to be processed. Therefore, the machine tool can realize synchronous linear operation of the first tool rest feeding module 301, the second tool rest feeding module 305 and the third tool rest feeding module 306 along the axial direction of the workpiece to be machined and linear feeding motion along the radial direction of the workpiece to be machined, and additionally realize the rotation motion of the workpiece to be machined, so that the high-efficiency and high-precision machining of a complex curved surface can be realized.
In addition, because the first tool rest feeding module 301, the second tool rest feeding module 305 and the third tool rest feeding module 306 of the tool rest feeding system are mutually independent, the working state of the turning tool 30102 can be switched through the expansion and contraction of the cylinder 30110, when the cylinder 30110 extends out, the turning tool 30102 is in the working state, and when the cylinder 30110 contracts, the turning tool 30102 is in the non-working state, so that there can be 7 processing modes according to the number of the turning tools 30102 participating in processing and the position where the turning tool 30102 is located, wherein the single-tool processing mode is the processing mode of a traditional lathe, so that the turning processing has more flexibility, and the universality and the practicability of the lathe are improved.
