Almost every CNC-related issue involves parameter settings. Indeed, if the machine has any wrong behavior, it may be due to incorrect parameter settings. Every CNC user should be aware of certain parameters related to safety, efficiency and ease of machine use.
Initialization state
Some code modes are automatically restored when the machine is powered up. Absolute or incremental; inch or metric; fast or linear motion; plane selection XY, XZ or YZ; and feed per minute or feed per revolution are code patterns that can be specified by parameters.
2. Fixed cycle
Most of these parameters control efficiency. For example: roughing and boring turning centers Multiple repeating cycles have a parameter that controls the distance the tool retracts between roughing passes.
3. Data input
The parameter controls whether the value without a decimal point is an integer or a fixed format. If set to an integer, the coordinate value 10 in inch mode will be treated as 10 inches. If set to a fixed format, it will be 0.0010 inches. This may affect program compatibility between machine and operator entries when sizing.
4. Communication and file loading
The parameters control the transfer method between the program and the CNC and the device/media used. Common choices include flash drives, memory cards, Ethernet or serial ports.
5. Program protection
For program protection, parameters can be used to prevent specified programs from being modified, deleted, and/or displayed. This allows you to protect important programs, such as probing programs.
6. User-defined G and M code
Use parameters to specify that the selected G or M code will execute the predetermined CNC program. This is important when developing custom macros for fixed-loop applications.
7. Inch conversion
When the parameter control switches the measurement system mode, the CNC only needs to move the decimal point to the right or left (no real conversion).
Knowing the parameters affects a given problem, which is the beginning of correcting the problem, and you must be able to find the parameter in question. Most CNC manufacturers record relevant parameters in a group, but because there are too many parameters, it is still difficult to find the parameters that are relevant to your particular problem. When you encounter this problem, although you can read it by getting a list of parameters, a better approach is to look at the documentation that describes the features that are bothering you.
Health and safety is the concern of every old man for children. It is also the expectation of children for the elderly. As the age increases, health problems become a common problem in society. As a child, because of long-term, you can't immediately know the health of your parents. If you have a smart device that can monitor your parents' health in real time.
Based on the concerns of children,Transtek provides a health monitor watch that can be used to monitor the health of parents. It is not only suitable for the elderly, but also for middle-aged people and children.

No matter how far away, children can know the health of their parents and elders in real time and care for their parents.
Facing the problems in trade, expanding domestic demand, stabilizing our customers, and ensuring the high precision and high efficiency of each batch of parts processing, this is what each of us should do. However, in the production of parts, there is often a high rate of scrap. It wastes raw materials and delays the delivery time of customers. Where is the reason? Below we analyze the process flow of CNC milling machine in the machining of mechanical parts:
First, the programming steps should be divided before programming, what is the process? The process of making raw materials into products is called a process. The entire process consists of several processes, which are cnc machining processes that are continuously performed by one or a group of workers at a work site. The process can be divided into several steps. For the CNC milling machine, one step refers to one continuous cutting.
Second, the cnc machining of the workpiece to the workpiece requires multiple processes, and sometimes it takes several steps in one process. For example, a template needs to be roughed, semi-finished, finished, drilled, reamed, and reamed. It can be arranged in one process and divided into several steps by a CNC milling machine.
Generally, the workpiece is machined on a CNC milling machine. The whole process should be completed in one setup as much as possible.
(1) Divide the process according to the principle of the first hole and the back hole. When machining a workpiece with a hole in the face, in order to improve the machining accuracy of the hole, the surface should be machined first and then the hole should be machined.
(2) Divide the process by roughing and finishing. For workpieces with high machining accuracy requirements, coarse and fine machining should be carried out separately, so that various deformations caused by roughing can be restored, and finishing should not be arranged immediately after roughing.
(3) Divide the process according to the tool used. CNC milling machines, especially CNC milling machines without a tool magazine, in order to reduce the number of tool changes, you can use the same process to process the same part on the workpiece and then use another knife. Processing other parts.
As a good helper for industrial manufacturing, CNC machining center use cutting fluids when working with parts. So what role does the cutting fluid play in processing :
First, cooling and cooling
Vertical Machine Center is high-speed working machines that cause temperature rise due to friction during use. Due to the liquid properties of the cutting fluid itself, it has the ability to cool and cool down. Its cooling function can significantly reduce the temperature generated when the workpiece is cut, reduce the wear of the tool and improve the life of the tool. At the same time, the temperature control can effectively prevent the workpiece. The effect of thermal expansion, warpage, etc. on machining accuracy is generated. At the same time, the cutting fluid can also cool the surface of the already processed surface to inhibit the generation of the thermal metamorphic layer.
Second, lubrication
In the process of high-speed Cnc Milling Center, the lubrication degree of each accessory needs to be controlled to a certain extent. The use of lubricant can reduce the damage caused by friction between components. In addition to cooling and cooling, the cutting fluid can also play a role in lubrication. During machining, the cutting fluid can reduce the friction, wear, fusion and adhesion between the rake face and the cutting, flank and workpiece surface. Ability. Under certain conditions, the use of high-quality cutting fluid can reduce the front and rear friction of the tool, thus achieving the effect of prolonging the tool life and obtaining a better surface quality of the workpiece.
Third, cleaning
The Cnc Vertical Milling Center will produce some debris, metal powder, or grinding wheel powder during the processing of the product. These things will adhere to the tool, or between the product processing surface and the machine tool moving parts. When it gets bigger, it will cause mechanical abrasion and wear, which will have a bad influence on the surface quality of the product, reducing the accuracy of the machine and the life of the tool. Therefore, when the cutting fluid is selected, it is required to have a cleaning effect, and it is pressurized at the time of use, so as to increase the flushing ability of the cutting fluid, and it is convenient to wash away the fines and powder in time.
Fourth, anti-rust
When using Cnc Milling Center, machine tools and workpieces are very susceptible to rust when they are exposed to moisture, sweat, oxygen, etc. in the surrounding environment. Especially in the summer when the temperature is high and the humidity is high, it is more prominent. Therefore, according to these actual conditions, when processing metal products and processing time is long, the cutting fluid must have the function of anti-rust, so that not only can the workpiece be rusted, but also the machine tool and the tool can be prevented from rusting. Troubled.
The cutting fluid plays a huge role in the metal cutting process. Therefore, it is necessary to select the most suitable high-quality cutting fluid when selecting the cutting fluid, so as to perfectly play the four functions of cutting, in order to extend the life of the tool and ensure the processing. Accuracy, rust prevention, improved cutting efficiency, lower cost of survival, and many other benefits.
Because the heat exchanger plate works for a long time, the surface of the heat transfer plate will produce different degrees of dirt or deposits, thereby increasing the flow resistance and reducing the heat transfer performance. These are mainly the pressure difference between the inlet and outlet pressure gauges and the temperature of the cold medium outlet. Reduced, so we have to clean it, we need to debug the experiment after the cleaning is completed to ensure the normal use of the product, then what are the things we need to pay attention to during the debugging process?
1. Reserve a certain inspection site around the location of the flat plate heat exchanger.
2. Before installing the apv plate heat exchanger, clean the pipeline connected to it to prevent sand, oil, welding slag and other debris from entering the plate heat exchanger, causing obstruction of the flow channel or damage to the plate.
3. When the plate heat exchanger is stopped and stopped in sequence, first close the high-pressure side medium solenoid valve, and then close the low-pressure side medium solenoid valve. When starting up, first open the low-pressure side medium plunger valve, and then open the high-pressure side medium plunger valve slowly after the medium fills the plate heat exchanger channel.
4. Check all clamping bolts for looseness before putting into use. If necessary, tighten them. In recent years, plate heat exchangers have replaced traditional shell-and-tube heat exchangers in airports, hotels, commercial buildings, etc., and have achieved good results.
5. Maintenance and maintenance:
If there is a large amount of muddy sand or debris in the medium, the supporting decontaminator produced by Weike should be placed in front of the plate heat exchanger. The gasket heat exchanger has a low fouling coefficient, and the fluid violently rolls between the plates to form a turbulent flow. The excellent plate design avoids the existence of a dead zone, so that impurities are not easily deposited and blocked in the channel, and a good heat exchange effect is ensured.
The above is all the things we need to pay attention to during the debugging process after cleaning. We only know these things to ensure the product usage rate.
Weike is a manufacturer of environmentally friendly plate heat exchangers. We believe that the company's technical design capabilities, manufacturing capabilities, enterprise scale and after-sales service will win your trust.
