Find the main cause first and then reduce the original error<\/h2>\n<\/p>\n
In March 2025, a heavy machinery factory in Jinan conducted an investigation and found that the thermal deformation of the workbench was the main reason for the deviation of plus or minus 0.03 mm.<\/p>\n
After that, the factory installed temperature rise sensors and adjusted the cutting depth and spindle speed. After a week, the error was suppressed within the range of plus or minus 0.01 mm. As a result, the scrap rate of this batch of products was directly reduced by 60%.<\/p>\n
Never blame the tool directly when you encounter processing quality problems. In a factory in Luoyang, in the ninth month of 2024, the boring hole size exceeded the deviation for three consecutive batches. The master who operated the machine tool repeatedly changed the boring bar and adjusted the feed speed, but the problem was still not solved.<\/p>\n
Later, after in-depth investigation, it was discovered that the root cause of the problem was that the positioning of the T-slot was offset by 0.05 millimeters. After the staff realigned the fixture, the production process returned to normal in just one shift.<\/p>\n

Human error offsets original error<\/h2>\n<\/p>\n

When the error on the workbench appears to be a negative value, the operator needs to add a positive value for calibration. When the error appears to be a positive value, a negative value should be added to offset it. The purpose of this is to try to make the numerical values \u200b\u200brepresented by the two equal.<\/p>\n
Specifically, during this time period in 2024, a workshop in Dalian used a 3D laser scanner to perform measurement operations, and the results showed that the actual deviation data was -0.02mm. In response to this situation, the staff added a compensation amount of +0.02mm to the CNC machining tool path for correction. The final technical effect achieved was that the flatness index was strictly controlled within the qualified range of 0.005mm.<\/p>\n
Calculations can only be carried out after the actual measurement is completed. Do not rely on feeling to estimate.<\/p>\n
The Shijiazhuang No. 1 factory uses the S8210 three-dimensional coordinate measuring equipment to perform a scanning operation on each batch of products, and then stores the distribution of these errors in the CNC system, and then performs automatic corrections during each cut. This eliminates the troublesome steps of manually repeatedly finding the tool position and performing test cuts, and the entire processing rhythm time is shortened.<\/p>\n

Throw the error in an insensitive direction<\/h2>\n<\/p>\n
<Strong>A boring machine factory in Xi'an discovered in 2025 that radial vibration has an impact on surface roughness. Therefore, the clamping angle of the clamp was adjusted from 90\u00b0. Finally the angle was adjusted to 85\u00b0. In this way, the direction of vibration is shifted.<\/p>\n
Let the vibration go in a specific direction that does not affect the critical flatness. After such optimization, the Ra value has been significantly reduced. The specific value is reduced from the original 1.6\u03bcm to the current 0.8\u03bcm. Ultimately, the appearance quality of the product reaches directly qualified standards.<\/p>\n
The so-called transfer cannot be performed casually. The factor of error sensitivity must be carefully considered here. Methods to ensure boring processing accuracy.<\/strong> Methods to ensure boring processing accuracy<\/strong> . There is a shipyard in Jiangyin. The shipyard wanted to try to transfer the axial error in 2023. However, the actual situation shows that the length of the workbench is the most critical tolerance item in the entire equipment. Because of this, adjustment in the axial direction becomes simply unfeasible. That is to say, what we often say is that the axis cannot rotate at all. The final result can only be to choose to go back to the original method and use compensation methods to solve this problem.<\/p>\n \n Harbin Factory No. 1 had 240 workbench blanks in 2024, with a total deviation of 0.12 mm. The actual size was divided into four groups, each group was controlled within 0.03 mm, and four sets of different tool heights were set up for processing respectively. In the end, they all fell within the tolerance of 0.02 mm, and the first pass rate increased from 72% to 95%.<\/p>\n When doing grouping, it does not mean that the more groups, the better. For the batch of work in Harbin, four teams were just enough to process it. If one more set is added, the additional labor costs required for changing fixtures and clamping will be even higher than the cost saved due to the reduction in fine boring processing volume.<\/p>\n When we carefully calculate these accounts, we will find that adding another group is not cost-effective at all. So when we decide how many groups to divide into, the key is to look at the overall cost-effectiveness.<\/p>\n \n In 2024, a precision machine tool factory in Changzhou adopted a processing method in which two worktables were used as benchmarks for each other and cross-bored. After three rounds of iterative improvement processes, the flatness parameter of a large table with an area of \u200b\u200bfour meters by three meters was finally adjusted from the original 0.05 mm to 0.008 mm, reaching the standard specified by the factory acceptance. The customer passed the inspection in one go.<\/p>\n When performing homogenization processing, the first trimming often fails to achieve the final standard. Specifically for the batch of products in Changzhou, after three rounds of grinding, the error value of approximately 0.015mm was eliminated, and it was not until the third round that it finally reached the qualified requirements.<\/p>\n When the workshop receives a production task and proceeds to the production scheduling and planning stage, sufficient time must be reserved for possible subsequent repeated repair processes. The deadline for delivery to the customer must not be set too urgently, because this matter must not be rushed.<\/p>\n In the workshop under your jurisdiction, regarding the workbench part of the floor-standing boring machine, in the precision control link, which specific direction error is the most difficult to suppress and solve?
