1. First, consider the processing order of parts. Drill first and then flatten (this is to prevent shrinkage during drilling); Rough turning first, then fine turning (this is to ensure the accuracy of parts); Process large tolerances first and then small tolerances last (this is to ensure that the surface of small tolerance dimensions is not scratched and prevent parts from deformation).
2. Then according to the hardness of the material, we choose a reasonable speed, feed rate and cutting depth. Carbon steel materials choose high speed, high feed rate and large cutting depth. For example: 1Gr11, choose S1600, F0.2, cutting depth 2mm; cemented carbide chooses low speed, low feed rate and small cutting depth. For example: GH4033, choose S800, F0.08, cutting depth 0.5mm; titanium alloy chooses low speed, high feed rate and small cutting depth. For example: Ti6, choose S400, F0.2, cutting depth 0.3mm. Take the processing of a certain part as an example: the material is K414, which is a special hard material. After many tests, S360, F0.1, and cutting depth of 0.2 were finally selected to process qualified parts.
Tool Setting Skills:
Tool setting is divided into tool setting instrument tool setting and direct tool setting. Some lathes in my previous work did not have tool setting instruments, so they were directly set. The tool setting skills mentioned below are direct tool setting. First, select the center of the right end face of the part as the tool setting point and set it as the zero point. After the machine tool returns to the origin, each tool that needs to be used is set with the center of the right end face of the part as the zero point; when the tool touches the right end face, enter Z0 and click Measure, and the tool compensation value of the tool will automatically record the measured value, which means that the Z-axis tool setting is done. The X-axis tool setting is a trial cutting tool setting. Use the tool to turn the outer circle of the part less. Measure the outer circle value (such as x is 20mm) and enter x20. Click Measure, and the tool compensation value will automatically record the measured value. At this time, the X-axis is also well set.
This tool setting method will not change the tool setting value after the machine tool is powered off and restarted. It can be used for mass production of the same part for a long time. There is no need to re-set the tool even if the lathe is turned off during the process.
Debugging skills.
Complete the Processing of Parts:
After the first trial cutting of the parts is completed, they will be produced in batches, but the qualification of the first piece does not mean that the whole batch of parts will be qualified, because in the process of processing, the tool will be worn due to the different processing materials. The processing material is soft, the tool wear is small, and the processing material is hard, the tool wear is fast. Therefore, during the processing, it is necessary to measure and check frequently, increase and decrease the tool compensation value in time to ensure the qualification of the parts.[Take the previously processed parts as an example: the processing material is K414, the total processing length is 180mm, because the material is very hard, the tool wears very quickly during processing, from the starting point to the end point, there will be a 10~20mm slight deviation due to tool wear, so it is necessary to add a 10~20mm slight deviation in the program manually, so as to ensure the qualification of the parts.
In short, the basic principle of processing: first rough processing, remove the excess material of the workpiece, and then fine processing; vibration should be avoided during processing; avoid thermal denaturation of the workpiece during processing. There are many reasons for the vibration, which may be excessive load; it may be the resonance of the machine tool and the workpiece, or it may be the lack of rigidity of the machine tool, or it may be caused by the passivation of the tool. The following methods can be used to reduce vibration; reduce the lateral feed rate and processing depth, check whether the workpiece is clamped firmly, increase the speed of the tool or reduce the speed to reduce resonance, and check whether it is necessary to replace the new tool.
Prevent Machine Tool Collision:
Machine tool collision is a great damage to the accuracy of the machine tool, and the impact on different types of machine tools is different. Generally speaking, it has a greater impact on machine tools with weak rigidity. Therefore, for high-precision CNC lathes, collisions must be absolutely eliminated. As long as the operator is careful and masters certain anti-collision methods, collisions can be completely prevented and avoided.
The main reasons for collisions are:
First, the diameter and length of the tool are entered incorrectly;
Second, the size of the workpiece and other related geometric dimensions are entered incorrectly, and the initial position of the workpiece is incorrectly positioned;
Third, the workpiece coordinate system of the machine tool is set incorrectly, or the machine tool zero point is reset during the processing process, resulting in changes. Machine tool collisions mostly occur during the rapid movement of the machine tool. The harm of collisions at this time is also the greatest and should be absolutely avoided. Therefore, the operator should pay special attention to the initial stage of the machine tool in the execution of the program and when the machine tool is changing the tool. At this time, once the program is edited incorrectly, the diameter and length of the tool are entered incorrectly, then it is easy to collide. At the end of the program, the sequence of the tool retraction action of the CNC axis is wrong, then a collision may also occur.
In order to avoid the above collisions, the operator should give full play to the functions of the five senses when operating the machine tool. Observe whether the machine tool has abnormal movements, sparks, noise and abnormal sounds, vibrations, and burning smells. If an abnormal situation is found, the program should be stopped immediately, and the machine tool can continue to work after the machine tool problem is solved. In short, mastering the operation skills of CNC machine tools is a gradual process and cannot be achieved overnight. It is based on mastering the basic operation of machine tools, basic mechanical processing knowledge and basic programming knowledge. The operation skills of CNC machine tools are not static. It requires the operator to give full play to the organic combination of imagination and hands-on ability, and is innovative labor.

Gas detection technology has a wide range of applications, in which a typical gas leak detection system is used to detect the tightness of the workpiece to be inspected. The external structure of the existing gas leak detection system includes several main components, such as an organic frame, a tracer gas source, a tracer gas inflation valve, a pressure sensor, a detection chamber, a leak detection valve, a return valve and a gas leak detector.
One of the detection methods is the chamber type gas leak detection system. The chamber type gas leak detection technology generally uses halogen gas, hydrogen or helium as the tracer gas, fills the tracer gas into the workpiece to be inspected, and uses the gas leak detector to detect the concentration of the tracer gas outside the workpiece to be inspected. If the detected tracer gas signal exceeds the set value of the gas leak detector, it indicates that the workpiece is leaking.
Chamber type gas leak detection system can be divided into vacuum chamber type gas leak detection system and atmospheric chamber type gas leak detection system. The working principle and structure of atmospheric chamber type gas leak detection system include tracer gas source, tracer gas inflation valve, detection chamber, leak detection valve, return valve and gas leak detector. The workpiece to be inspected is placed in the detection chamber, and the workpiece to be inspected is connected with the tracer gas source through the connecting pipe. During detection, after the door of the detection chamber is closed, the tracer gas inflation valve connecting the workpiece to be inspected is opened, and the tracer gas is filled into the workpiece to be inspected. The pressure sensor detects that after the inflation pressure in the workpiece to be inspected reaches a certain value, the tracer gas inflation valve is closed, and the leak detection valve and return valve are opened at the same time. If the workpiece to be inspected leaks, the gas in the workpiece to be inspected will overflow from the leak hole and enter the detection chamber under the effect of differential pressure. The gas leak detector samples from the detection chamber and judges whether the workpiece leakage exceeds the standard according to the size of the tracer gas signal obtained.
For the vacuum chamber type gas leak detection system, there is a vacuum pump and a vacuum valve connected to the detection chamber. Before the tracer gas is filled, there is no need to vacuum the detection chamber for the atmospheric chamber type gas leak detection system.
The main features of the chamber type gas leak detection system are high leak detection accuracy, fast production rhythm and simple operation.
The sampling space of the chamber type gas leak detection system is the space of the detection chamber and the relevant pipe space connected with the gas leak detector. Before the tracer gas is filled in the chamber type gas leak detection system, the gas in the clean sampling space is the reference background, and the tracer gas signal left in the sampling space after detection is called background noise. The tracer gas in the background noise may leak into the sampling space from the gas leak detection system itself, or it is the residual accumulation of the previous detection. The background noise of the tracer gas will increase with the repeated operation of the system. When the background noise exceeds a certain level, it will lead to the failure of the leak detector to operate normally, and even lead to false judgment of the detection results. The existing technology cannot effectively eliminate the residual accumulation of tracer gas, and it is usually necessary to eliminate the impact of background noise through repeated empty machine operation. The equipment operation efficiency is low, resulting in energy waste.

One of the detection methods is the gas hood type gas leak detection system. The gas hood type gas leak detection system uses halogen gas, hydrogen or helium as the tracer gas, fills the tracer gas into the detection chamber (i.e. the gas hood), and uses the gas leak detector to detect the concentration of the tracer gas in the workpiece to be inspected. If the tracer gas index is detected to exceed the set value of the gas leak detector, it indicates that the workpiece to be inspected has leakage.
The working principle and structure of the above gas hood type gas leak detection system include a tracer gas source, a tracer gas inflation valve, a detection chamber (i.e. a gas hood), a workpiece connecting pipe, a leak detection valve, a return valve, and a gas leak detector. The backflow valve is connected with the gas leak detector, and the detection chamber is connected with the tracer gas source through the connecting pipe. After the door of the detection chamber is closed, the tracer gas inflation valve is opened, and the tracer gas is charged into the detection chamber. When the pressure sensor detects that the inflation pressure of the detection chamber reaches a certain value, the tracer gas inflation valve is closed. Open the leak detector and return valve. If the workpiece to be inspected leaks, the gas in the detection chamber (i.e. the gas hood) will overflow from the workpiece leak hole into the workpiece to be inspected under the effect of differential pressure. The gas leak detector samples from the internal space of the workpiece to be inspected, and judges whether the workpiece leakage exceeds the standard according to the size of the tracer gas signal obtained.

When we want to do a structural integrity verification and bubbling point test for hydraulic filters, we may want to do it by a machine automatically. Then a test stand complying with ISO 2942-2004 may be suitable for doing the test.
It specifies a bubble-point test method for confirming the manufacturing dependability of your filter factor or figuring out the localization in the most significant pore in the filter factor by figuring out the first bubble point. Verification of manufacturing dependability specifies the acceptability in the filter aspects for additional use or tests. The first bubble noint is recognized throuah continuation in the manufacturing intearity testIt is under no conditions an operating sign of a filter element in specific. It cannot be employed for extrapolation for the ideas of purification ranking, performance or maintenance capacity and really should be used for details only.
