What about manual return reference points for CNC lathes and CNC machining centers?

According to the classification of the mechanical structure of CNC lathes, they are generally divided into two types: vertical CNC lathes and horizontal CNC lathes. Specifically, you can learn about the CNC lathe of Shanghai Jiatai CNC machine tool ****, which is still good, affordable, good quality, and good after-sales service, I hope it can help you. Address:

Building 2, No. 669 Zhongde Road, Songjiang District, Shanghai **:

1；The reference point of the CNC lathe and the machining center are the same theoretically set at **, but the general ones are located on the maximum stroke away from the side of the workpiece, 2;Generally, most of the CNC machine tools need to leave the reference point for a distance before returning to the reference point, which is necessary to learn CNC to understand, but now the new machine tools also do not need, very few.

3；30mm is just a reference value, it is not necessary to have 30mm, but it is best to be greater than this number, not less than 30mm, if it is less, it is easy to overtravel the alarm.

I'm not familiar with machining centers, so I'll explain it with a CNC lathe.

1.CNC lathes are generally composed of two stoppers near the guide rail, away from the chuck, the farthest one is generally the stroke stopper, which controls the stroke of the lathe, and the one next to it is the zero stopper, and the two stoppers are staggered and not in the physique slot. When the corresponding contact of the travel switch touches the zero return iron, the zero return is completed.

2.The shape of the stopper is shaped, when the contact touches the left side of the stopper, it slows down, but continues to the right, and when the contact is released to the right, the return to zero is completed. That is, there must be 3 processes to return to zero:

1.Didn't touch the stopper 2Press to the stopper to slow down 3

Leave the stopper. If the contact is pressed against the stop at the beginning, there will be no pulse signal, no deceleration process, and no return to zero. Therefore, it is required to leave the reference point 30mm in the direction of the chuck, and return to zero when leaving the stopper.

3.This is actually very simple, you just walk in the direction of the chuck, 30mm, very small, hehe.

1.In fact, the reference point mentioned in the book is also the "mechanical origin" that is commonly referred to

Machine tool manufacturers generally set the origin of the machine at the limit point of the stroke of each axis.

2.Basically, it's all suitable.

3.Just look at the "mechanical coordinates" in the coordinate system. If you go back to square one, it's zero. See if the inner value is less than 30mm, but generally large machine tools are 50mm. That is, the "pos" button on the control panel.

1.The lathe is set at the extreme point farthest from the origin of the machine.

2.Generally, yes.

3.Just a reference. The key is to practice.

You can go to the CNC China Forum. Learn about it.

Calibrating the coordinate system, back to the mechanical origin, the origin of the machine tool is set at the factory, each axis is controlled by the position switch, and the switch is back to the zero point when it is touched in the process of going back, and the machine tool coordinate system is automatically corrected to 0

The coordinate system of the machine tool is also called the external coordinate system of the machine, and the coordinate system set during programming is the workpiece sitting system, which is established inside the coordinate system of the machine tool and determined by the data in the memory.

In the case of data unchanged, whether the external coordinate system (machine tool coordinate system) accurately determines the position of the workpiece coordinate system, because the mechanical part may change, so the reference point is very important, of course, if the operator determines that the mechanical part does not change, it can not be 0.

1. No one requires you to go back to the reference point, if you don't process it, you can't go back.

3. The motor of the absolute position encoder of the CNC machine tool does not need to go back to the reference point, and can remember the position.

Summary. 1.When manually returning to the origin, the axis of the return to the origin first moves to the direction of the origin at the ** movement speed set by the parameter; When the deceleration stop depresses the origin deceleration switch, the return to the 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 CNC system begins to detect the grid point or zero pulse of the encoder; When the system detects * grid points or zero pulses, the motor immediately stops rotating, and the current position is the zero point of the machine tool.

2.The return to the origin axis first moves to the origin direction at the speed of ** movement set by the parameters; When the deceleration block depresses the origin deceleration switch, the return to zero axis decelerates to the reference point positioning speed where the system parameters set slower, and the axial moves in the opposite direction; When the deceleration switch is released, the CNC system begins to detect the grid point or zero pulse of the encoder; When the system detects * grid points or zero pulses, the motor immediately stops rotating, and the current position is the zero point of the machine tool.

How to return to the origin operation of CNC lathes.

The way of returning the reference point of the CNC machine tool can generally be divided into several kinds such as acres of socks and socks: 1When manually returning to the origin, the axis of the return to the origin first moves to the direction of the origin at the ** movement speed set by the parameter; When the deceleration stop depresses the origin deceleration switch, the return to the 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 CNC system begins to detect the grid point or zero pulse of the encoder; When the system detects * grid points or zero pulse rapid impulse, the motor immediately stops rotating, and the current position is the zero point of the machine tool.

2.The return to the origin axis first moves to the origin direction at the speed of ** movement set by the parameters; When the origin deceleration switch is depressed in the good section of the deceleration block, the return to zero shaft is decelerated to the reference point positioning speed set slower by the system parameters, and the axial moves in the opposite direction; When the deceleration switch is released, the CNC system begins to detect the grid point or zero pulse of the encoder; When the system detects * grid points or zero pulses, the motor immediately stops rotating, and the current position is the zero point of the machine tool.

3.The return to the origin axis first moves to the origin direction at the speed of ** movement set by the parameters; When the deceleration block depresses the origin deceleration switch, the return to zero axis decelerates to the reference point positioning speed where the system parameters set slower, and the axial moves in the opposite direction; When the deceleration switch is released, the zero shaft is reversed again; When the deceleration switch is pressed down again, the zero axis is returned to run at the speed of blocking the code to find the zero pulse, 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 pulses, the motor immediately stops rotating, and the current position is the zero point of the machine tool. 4.

After the return to origin axis is connected to the zero letter Qihu, it moves to a fixed direction at a slower speed at the current position of Gao Hengxi, and at the same time, 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 immediately stops rotating, and the current position is the zero point of the machine tool. When the CNC machine tool returns to the reference point and fails, first check whether the deceleration block is loose and whether the deceleration switch is fixed firmly or damaged. Check the length of the speed brake block and whether the installation position is reasonable; Check the pulse encoder or grating ruler, etc.

Hello, I'll help you solve this problem! The operation steps are as follows: 1. When manually returning to the origin, the axis of the return to the origin first moves to the direction of the origin at the fast moving speed set by the parameters; When the deceleration stop depresses the origin deceleration switch, the return to the 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 lack of grid or zero pulse of the encoder; When the system detects the first grid point or zero pulse, the motor immediately stops rotating, and the current position is the zero point of the machine tool.

2. The axis of return to the origin first moves to the direction of the origin at the speed of rapid movement set by the parameters; When the deceleration block depresses the origin deceleration switch, Fu Huibi decelerates back to the zero axis to the slower reference point positioning speed set by the system parameters, and the axial moves in the opposite direction; When the deceleration switch is released, the CNC system begins to detect the grid point or zero pulse of the encoder; When the system detects the first grid point or zero pulse, the motor immediately stops rotating, and the current position is the zero point of the machine tool. You can follow my steps to try it, and if you have any questions, you can give me feedback in time!

When the original system does not have an absolute encoder, it is a method to establish a mechanical coordinate system, mainly to let the system know the position of the mechanical parts of your saddle and skateboard in the machine tool, and the process is some standard processes stipulated by the operating system: in fact, as long as the zero position is started before the zero collision block. After the system receives the address signal triggered by the zero-return collision block, it waits for the next appearance of the zero point of the servo motor, and the system receives the zero-return end.

The machine has a buffer distance in the process of referencing the point, just like a car brake, which has to be advanced by some distance. Therefore, before returning to the reference point, it is necessary to move each axis in the opposite direction of the return reference point for a certain distance, and then perform the return to zero operation, and the instant speed of returning to zero is very fast. Too close is easy to overtravel.

Manually adjusting a value is equivalent to a reference point.
