The reference point of a small CNC machine tool for CNC machining is a fixed position point used for detecting and controlling the movement of the machine tool.
The position of the reference point for small CNC machine tools is accurately adjusted by the machine tool manufacturer on each feed axis using a limit switch, and the coordinate values have been input into the CNC system. Therefore, the coordinate of the reference point to the origin of a small CNC machine tool is a known number.
Usually, on small CNC milling machines, the machine tool origin and reference point coincide; On small CNC lathes, the reference point of the machine tool is the farthest limit point from the machine tool origin.
After disassembling and assembling the transmission machinery of each axis of a small CNC lathe, replacing the feed servo motor, and repairing the position detection device, the reference point position of the machine tool will be inaccurate. The CNC lathe manufacturer needs to adjust the return reference point of the machine tool.
