Solution for the machine tool not working properly due to encoder battery failure
The CNC machine does not operate normally after the encoder's backup battery is exhausted and the encoder's backup battery is powered down or lost. In this case, it is necessary to re-set the reference point or the origin to correct the coaxiality. The spindle of the machine tool is moved to the proper position so that the spindle of the CNC machine tool is coaxial with the corresponding drill sleeve. That is, to find the position of the workpiece processing part.
The method of correcting the coaxiality will be connected to the M port of the machine tool as follows. At this time, the CNC machine tool can be jogged in the corresponding coordinate axis mode in the mode, and the speed of the CNC machine tool can be adjusted by the magnification. Insert the special measuring tool with the head or the insert into the inner hole of the spindle. The inserting part of the tool should be matched with the inner hole of the spindle or the corresponding axis of the handwheel to adjust the position of the CNC machine tool or the cnc machining center. Slowly push the probe into the mold, and stop paying attention after avoiding the stylus or the equipment in the place where the probe is rusted or worn.
Then slowly rotate the spindle one or several times, and record the swing of the lower needle (for horizontal machine tools, there are four positions of up and down, left and right, for vertical machine tools, there are four positions before, after, and so on), if coaxiality The requirements of the coaxiality within the required range can be referred to the static accuracy of the machine tool according to the swing condition, jog the corresponding axis of the machine tool, and re-adjust the position of the machine tool until the coaxiality meets the requirements, that is, the position of the workpiece processing part is consistent. At this point, the coaxiality is corrected.
From the above conditions and the machining program, the center coordinate of the hydraulic tappet hole whose coordinates are the center of the hydraulic tappet hole is known. Connect and press the key on the operation panel, then press the soft key to display the screen, the parameter will be rewritten at this time. Call the parameter to disconnect the machine from the position and position according to the information prompt, then re-open the machine power and return to the reference point. The reference point found at this time may not meet the requirements of the position of the workpiece.
Move the CNC machine tool to one or the above-mentioned known conditions. When the CNC machine tool is at this position, the data of the coordinate axis in the program is the position or position. Use the above method to find the coaxiality to find the coaxiality. The coordinate data is used to move the CNC machine tool back to the coordinate data by obtaining another coordinate data. If an overtravel alarm occurs during the movement, the data of the corresponding axis of the parameter is modified to eliminate the overtravel alarm.
