While the price of CNC vertical lathes is low, the processing efficiency is 2 to 3 times higher than that of traditional machine tools, and the performance has reached the international first-class level, showing a very high cost performance. The successful development of this project has led to the continuous innovation and development of large-scale CNC vertical lathe production technology, which has improved the manufacturing capacity of large-scale CNC vertical lathes in my country. At the same time, after this project has occupied the domestic market, this product will drive the overall market price of gear machine tools to drop. In this way, machine tool users will save the cost of purchasing equipment while using better performance and higher precision machine tools. Improved efficiency and development speed, and at the same time enhanced the enterprise’s confidence in domestic machine tools, and promoted the development and growth of local machine tool enterprises.
The working principle of the CNC vertical lathe tool magazine: pre-install the turning tool on the tool holder, and then place the tool holder on the radial position of the tool holder frame in turn. When the tool needs to be changed, the CNC system issues a command to drive the servo The motor drives the large ring gear to rotate the corresponding angle through the anti-backlash gear to rotate the corresponding tool to the tool change position. At this time, the vertical tool post enters the tool change position, removes the tool holder, and returns to the workpiece position to continue processing the next process. The rotational movement of the grinding wheel of a CNC vertical lathe generally does not require speed adjustment, it can be driven by a three-phase asynchronous motor, and only one-way rotation is required. When the capacity is large, it can be started by Y-triangular depressurization. In order to ensure its processing accuracy, make it run smoothly, and ensure that the inertia of the worktable is small and no impact when the reciprocating movement of the worktable is reversed, hydraulic transmission is adopted to realize the reciprocating movement of the worktable and the grinding wheel. The box feeds horizontally.
Straight shank round bar to knife. This method is to mount and clamp a straight shank round bar on the spindle of a CNC vertical lathe. Suppose the X-axis is centered: move the main shaft to slowly approach one side of the workpiece. When approaching, use a parallel block to insert the gap between the round bar and the machined surface of the workpiece. When it feels easy to advance, take out the parallel block and continue Move the spindle, and then insert the parallel block. If it is still easy to insert or cannot insert, move the spindle again, reciprocating until it can just be inserted, and then reset the relative coordinate X axis to zero; then move the CNC vertical The multi spindle of the lathe is moved to the other side of the workpiece, and the total value of the X axis is obtained by the same operation method, and the coordinate system is set after moving the spindle to half of the total value (in the middle of the workpiece). The advantage of this method is simple operation and low value of the tools required; the disadvantage is that the operation steps are many, the process is cumbersome, and the accuracy of tool setting is not high.
