What is the location of the reference point of the CNC lathe manufacturer?

The position of the reference point of the CNC lathe manufacturer is adjusted by the CNC lathe manufacturer with a limit switch on each feed shaft, and the coordinate values have been input into the numerical control system. 

Therefore, the coordinate of the reference point to the origin of the CNC lathe is a known number. 

The disassembly and assembly of each shaft transmission machinery of the CNC lathe, the replacement of the feed servo motor and the repair of the position detection device will all lead to the inaccurate position of the reference point of the CNC lathe. The CNC lathe manufacturers need to adjust the return reference point of the CNC lathe.

There are four ways to adjust the reference point of CNC lathe manufacturers: 

1. When returning to the origin manually, the back-to-origin axis first moves to the origin at the fast movement speed set by the parameters; when the deceleration block presses the origin deceleration switch, the return-to-origin axis decelerates to the slower reference point positioning speed set by the system parameters and continues to move forward; when the deceleration switch is released, the numerical control system begins to detect the grid point or zero pulse of the encoder. 

When the system detects * grid points or zero pulses, the motor stops immediately, and the current position is the zero point of the CNC lathe manufacturer. 

2. The back-to-origin axis first moves to the origin at the fast moving speed set by the parameters; when the deceleration block presses the origin deceleration switch, the return-to-zero axis decelerates to the reference point positioning speed where the system parameters are set slowly, and moves in the opposite direction; when the deceleration switch is released, the numerical control system begins to detect the gate point or zero pulse of the encoder. 

When the system detects * grid points or zero pulses, the motor stops immediately, and the current position is the zero point of the CNC lathe manufacturer. 

3. The back-to-origin axis first moves to the origin at the fast moving speed set by the parameters; when the deceleration block presses the origin deceleration switch, the return-to-zero axis decelerates to the reference point positioning speed where the system parameters are set slowly, and the axis moves in the opposite direction; when the deceleration switch is released, the return-to-zero axis is reversed again. 

When the deceleration switch is pressed down again, the zero axis is returned to find the zero pulse speed, and the numerical control system begins to detect the grid point or zero pulse of the encoder; when the system detects * grid points or zero pulse, the motor stops immediately, and the current position is the zero point of the CNC lathe manufacturer. 

4. After the back-to-origin axis receives the zero signal, it moves to a fixed direction at a slower speed at the current position, and the numerical control system begins to detect the grid point or zero pulse of the encoder; when the system detects * grid points or zero pulse, the motor immediately stops rotating, and the current position is the zero point of the CNC lathe manufacturer.
