850 machining center is one of the most common CNC machine tools. It is easy to have taper problem when using 850 machining center boring. The following after-sales maintenance engineer of Dongyue in Shaanxi will share the solutions. 1. First remove the tool, CNC program failure. If the tool is worn and the program is not correct, the work will not be done. 2. Check the verticality of Z-axis and worktable. This is the main factor that leads to the taper in the boring of 850 machining center. You can use a dial indicator to draw a circle on the worktable. Generally, you can draw a circle with a diameter of 300 mm, and the error is within 0.02 mm. 3. Check the horizontal accuracy of the machine tool. The level of the machine tool is not good also affects the boring accuracy. Generally, the horizontal error of the machine tool within one meter is less than 0.02mm. 4. Check the reverse clearance of Z axis. You can press the dial indicator, and then turn the first round to see if the first round goes 0.01mm, and the dial indicator also goes 0.01mm. If not, parameters can be used to compensate. As long as according to the above method, step by step to check and deal with, believe that 850 machining center boring taper problem can be successfully solved.
