What is the reason why the size of the CNC lathe is wrong when it is turned on 10

1. Whether the gap of the screw rod is too large or too tight.

2. Whether there is a problem with the rotation and tightening of the tool holder, whether there is garbage in the tool holder, and whether the positioning is accurate, that is, whether the magnet and magnetic sensing element (Hall element) in it are loose and poor.

3. Whether the cutting force during processing is appropriate.

4. The gap compensation in the system parameters and the parameters such as the rotation speed of the tool holder are reasonable.

CNC lathes and turning centers are a kind of high-precision and high-efficiency automatic machine tools. Equipped with a multi-station turret or a driven turret, the machine tool has a wide range of processing performance, can process linear cylindrical, oblique cylindrical, circular arc and a variety of threads, grooves, worms and other complex workpieces, with linear interpolation, arc interpolation various compensation functions, and in the mass production of complex parts play a good economic effect. CNC machine tools automatically process the processed parts according to the pre-programmed processing program.

The processing process route, process parameters, motion trajectory, displacement, cutting parameters and auxiliary functions of the parts are compiled into a processing program sheet in accordance with the instructions and program format specified by the CNC machine tool, and then the content in the program sheet is recorded on the control medium, and then input into the CNC device of the CNC machine tool to direct the machine tool to process parts.

This whole process from the analysis of the part drawing to the production of the control medium is called the preparation of the numerical control program. The difference between CNC machine tools and ordinary machine tool processing parts is that CNC machine tools automatically process parts according to the program, while ordinary machine tools are operated by people, as long as the program that controls the action of the machine tool can be changed to achieve the purpose of processing different parts. Therefore, CNC machine tools are particularly suitable for processing parts in small batches and complex shapes that require high precision.

Because the CNC machine tool needs to process parts according to the program, the programmer enters the CNC device to direct the machine tool after the program is prepared. The input to the program is through the control medium.

It may be that the machining accuracy of the machine tool is, especially the domestic machine tool, the accuracy is poor. This is also the fundamental reason why China's industry lags behind Japan, Europe and the United States, and it is impossible for you to eliminate this error, which means that you can't drive a BYD as fast as a Ferrari. Unless you can buy a better CNC (numerical control machining center) I think it's ** should be something you can't afford, and it's hard to buy, it's not that you can buy it if you have money, and you need the support of policies and overseas relations.

Positive and negative two wires are the processing standards of many ordinary domestic CNC lathes, and the standard of Japanese ordinary machine tools is plus or minus a wire, don't underestimate this silk, this silk often represents the rise and fall of a nation. You can take good care of your lathe and maybe get better. But shaft runout is present in all lathes, milling machines, machining centers, and your machine itself is so standard, you can only take some orders of plus or minus two wires.

I don't quite understand how you got here? Is the machine new or old?

Is there a running position phenomenon after start-up, or is there sometimes, or does it occur from time to time during processing?

I suggest looking at the gap compensation in the system parameters, as well as whether the parameters such as the rotation speed of the turret are reasonable.

Whether the cutting force during your machining is inappropriate.

Is there a problem with the rotation and tightening of the knife holder. There is no trash in the knife holder. Whether the positioning is accurate or not is whether the magnets and magnetic inductive elements (Hall elements) in it are loose and defective.

Is the clearance of the screw too large or too tight?

Anyway, there are many related problems, and the problem needs to be found out little by little by using the elimination method.

CNC lathe outer circle, diameter 35, s1200 how the car feels not smooth and convex, but with the dial gauge along the processed outer circle Z detection error only What should I do? Is it a machine problem? I've just run into this problem.

Check the axial thrust bearing in front of the Z-axis screw on the left side of the operator, the clearance may be too tight, the rotation is not smooth, and it is not a few days after buying. It is a fine turning knife with a knife tip.

Do you perform a mechanical zeroing operation after powering it on?

Hello dear, <>

1. The result of the mechanical clearance and the influence of the knife together. If the size is large and the size is small, it is likely that this is the reason. 2. The cutter is not tightened, and some parts on the transmission chain are loose.

If the size keeps getting bigger or smaller all the time, it could be this reason. 3. The drive module is aging, resulting in step dropping. If the feed motor is a servo motor, it will alarm when it drops I hope my answer will help you, Finally, I wish you good health and a happy mood!

This is a typical unstable phenomenon, which will be big and small. That is to say, the accuracy of your workpiece has exceeded the existing accuracy of the machine tool, and the scrap rate is relatively high.

This situation is usually due to excessive force on the x-axis, perhaps caused by the impact of the machine tool, or the machine tool is too old. The backlash of the machine tool is too large, and so on. The solutions are:

Adjust the backlash of the x-axis. If necessary, it needs to be done by a mechanic. By changing the path of the program and using the method of eliminating the gap (the same as the path of the general car), the phenomenon of scrapping due to dimensional instability can be greatly reduced.

Classification of CNC lathes:

CNC lathes can be divided into two categories: horizontal and vertical. There are two kinds of horizontal lathes: horizontal guide rail and inclined guide rail. High-grade CNC horizontal lathes generally use inclined guide rails.

According to the number of tool holders, it can be divided into single tool holder CNC lathe and double tool holder CNC lathe, the former is two coordinate control, and the latter is four coordinate control. Most of the double turret sleeper cars use inclined guide rails.

Daily maintenance of CNC lathes:

Here are a few examples of routine maintenance that are of a general nature.

1.Do a good job of cleaning and lubricating the guide rail surface every day, and the machine tool with automatic lubrication system should regularly inspect and clean the automatic lubrication system, check the amount of oil, add lubricating oil in time, and check whether the oil pump starts and stops regularly.

2.Check whether the automatic lubrication system of the headstock is working properly every day, and change the lubricating oil of the headstock regularly.

Hello dear, according to your question, what is the reason for the automatic reduction of the size of CNC machine tool processing, the answer to Hu Zhao for you to inquire about the following possibilities: 1. Thermal deformation of machine tools. If it is caused by thermal deformation of the machine tool, it will only change for a period of time after the pants are turned on, and then it will stabilize.

2. The tool is not clamped. The tool is not clamped, which can be confirmed or ruled out by simply checking it. 3. The screw rod in the X direction is too tight, causing the step to drop.

After ruling out 1 and 2, it is suspected that it is caused by a step drop and can be checked with a dial gauge.

Summary. Hello dear, the reasons for the automatic reduction of the size of CNC machine tool processing are as follows: What is the reason for the automatic reduction of size in CNC machine tool processing.

Hello dear, the reasons for the automatic reduction of the size of CNC machine tool processing are as follows: 1. The result of the mechanical clearance and the influence of the knife together. If the size is sometimes large and sometimes small, it is likely that this is the reason for the confusion. 2. The cutter is not sharpened, and some parts on the blind transmission chain are loose.

If the size keeps getting bigger or smaller all the time, it could be this reason. 3. The drive module is aging, resulting in step dropping. If the feed motor is a servo motor, it will alarm when the step is dropped.

Summary. Hello, I have seen your question and am sorting out the answer, please wait for a while What is the reason why the size of the CNC lathe is not right when it is turned on.

The gap compensation in the system parameters is also related to whether the parameters such as the rotation speed of the turret are reasonable. Three: whether there is a problem with the rotation and tightening of the tool holder, whether there is garbage in the tool holder, and whether the positioning is accurate may be caused by these reasons.

I'm sorry I don't understand, but can you elaborate on that?

In response to this problem, we can say that the startup size of the CNC lathe may be wrong, this is because the accuracy of the CNC lathe is affected by the temperature change, and when the temperature changes, the size of the CNC lathe will also change. In addition, the accuracy of the CNC lathe is also affected by vibration, and if the vibration is too large, it will also affect the size of the CNC lathe. In addition, the accuracy of the CNC lathe is also affected by the lubricating oil, if the lubricating oil is insufficient or the oil cover is not of good quality, it will also affect the size of the CNC lathe.

In addition, the accuracy of the CNC lathe is also affected by the tool, if the wear of the tool is too large, it will also affect the size of the CNC lathe. Therefore, in order to ensure the accuracy of the CNC lathe, we should pay attention to the change of temperature, reduce vibration, ensure the quality of the lubricating oil, change the tool regularly, and check the size of the CNC lathe regularly to ensure the accuracy of the CNC lathe.

Every time the CNC lathe is turned on, the X-axis size always changes.

Every time the CNC lathe is turned on, the X-axis size change may be caused by the following reasons:1System Setup Error:

It may be due to the wrong parameter setting in the CNC system, which leads to the size change of the x-axis. This can be solved by rechecking the system code and making sure the parameters are correct. 2.

Machine tool wear: Prolonged use can lead to wear and tear on machine parts, especially those involving the X-axis. If the guide rails, lead screws and other components of the machine tool are severely worn, it may lead to changes in the size of the x-axis.

In this case, the machine needs to be serviced or worn parts replaced. 3.Electrical Issues:

Sometimes poor electrical connections or power supply problems can lead to unstable movement of the CNC lathe, which in turn will cause changes in the size of the x-axis. This can be resolved by checking the electrical connections and making sure the power supply is stable. 4.

Programming errors: If there is an error while writing the NC program, it can lead to an error in the distance traveled by the x-axis. This procedure needs to be rechecked and corrected.

For these possible reasons, you can investigate them one by one and find solutions to ensure the stability of the X-axis size mu Lu after each boot of the CNC lathe.
