An Analysis of SeveralPointsin Horizontal Lathe
 1, horizontal lathe zero

   The origin of the horizontal lathe coordinate system is called the horizontal lathe zero point (X = 0, Y = 0, Z = 0). Horizontal lathe zero point is a fixed point on the horizontal lathe, determined by the manufacturer in advance. Horizontal lathe zero point M is the starting point of the zero point of the horizontal lathe coordinate system and other coordinate systems, such as the workpiece coordinate system, the programming coordinate system and the reference point (or reference point) in the horizontal lathe. The origin O of the horizontal lathe coordinate system (XOZ) of the horizontal lathe is generally located at the end of the chuck or at a distance from the end of the jaw or at the reference point of the horizontal lathe.
 
   The origin of the horizontal lathe coordinate system (X YZO) of the CNC milling machine is generally located on the upper left corner of the horizontal lathe reference point or the horizontal lathe table.

2, horizontal lathe reference point (reference point)

  Horizontal lathe reference point (R) is defined by the horizontal lathe manufacturer's artificial point, the horizontal lathe reference point (R) and the horizontal lathe zero (M) between the coordinate position relationship is fixed and stored in the NC The system of the corresponding horizontal lathe data, is generally not allowed to change. (R) limit position of the horizontal lathe reference point (R), but at the same time must be able to accurately measure the horizontal lathe reference point (R) relative to the horizontal lathe zero (M) Geometric size distance and stored in the corresponding CNC lathe lathe data, in order to ensure that the original design of the horizontal lathe coordinate system is not destroyed. After the control system is activated, all axes must be referenced once again to correct the travel measurement system. Most horizontal lathes can automatically return to the reference point, such as power loss caused by the control system to lose the existing coordinates, you can return to the reference point, and regain the exact location value.

    The position of the reference point R is precisely predetermined on each axis with the stopper and the limit switch. The reference point to the horizontal lathe zero point coordinates is a known number, the reference point is located in the processing area of the edge.

3, workpiece zero (programming zero)

   By the operator or programmer in the preparation of parts program, the workpiece to a fixed point for the establishment of the zero point of the coordinate system, known as the workpiece coordinate system (or programming coordinate system). The zero point of this workpiece coordinate system is called the workpiece zero (or programmed zero). The principle of selecting the workpiece zero is that the dimensions in the workpiece drawing are easily converted to coordinate values, as far as possible, using the pattern size as the coordinate value. The measuring system can be easily checked, clamped, adjusted, easily oriented, positioned.
    Horizontal lathe The workpiece zero is on the spindle axis of the right edge of the finished contour or the left edge. Milling machine workpiece zero part of the workpiece to select the outer corner, the workpiece zero after the selected (often relative to the reference point of the distance), in the start of the horizontal lathe into the CNC device to go.
