What is the difference between traditional milling and CNC milling

CNC milling refers to the use of rotating multi-edge tools to cut workpieces, which is a highly efficient machining method. When working, the tool rotates and the workpiece moves, and the workpiece can also be fixed, but the rotating tool must also move at this time.cnc turning service

Traditional milling is mostly used for milling simple shapes and features such as contours and grooves. It is suitable for processing planes, grooves, various forming surfaces and special shapes of molds, etc. It is mainly used for processing molds, gauges, and thin-walled complex curved surfaces. , Artificial prostheses, blades, etc.

When selecting the content of CNC milling, the advantages and key roles of CNC milling machine should be fully utilized.

Classification of common faults of CNC machine tools

1. Deterministic failure

Deterministic failure refers to the failure of the CNC machine tool if the hardware in the host computer of the control system is damaged or as long as certain conditions are met. This type of failure phenomenon is the most common on CNC machine tools, but because it has certain rules, it also brings convenience to maintenance. Deterministic failures are irrecoverable. Once a failure occurs, if it is not repaired, the machine tool will not Automatically return to normal. But as long as the root cause of the failure is found, the machine tool can be restored to normal immediately after the repair is completed. Correct use and careful maintenance are important measures to prevent or avoid failures.cnc machine service

2. Random failure

Random failures are accidental failures of exponential control machine tools in the working process. The causes of such failures are relatively hidden, and it is difficult to find out its regularity, so it is often called “soft failure”. Random failure analysis and fault diagnosis It is more difficult. Generally speaking, the occurrence of faults is often related to many factors such as the installation quality of the components, the setting of parameters, the quality of components, the imperfect software design, and the influence of the working environment. Random failures are recoverable. After a failure occurs, the machine tool can usually be restored to normal by restarting and other measures, but the same failure may occur during operation.

Strengthening the maintenance and inspection of the CNC system, ensuring the sealing of the electrical box, reliable installation, connection, and correct grounding and shielding are important measures to reduce and avoid such failures.

Are memory foam mattresses harmful to the human body?

What is memory foam? Is this material healthy? is it safe? Will it harm your health? For this reason, I deliberately collected a lot of information related to memory foam. Today we will have a good chat about this memory foam.

Memory foam was developed in the 1960s. In order to protect the safety of astronauts, this material was invented. Together with GPS, he is called the two great inventions of space technology. The greatest science in the 21st century will be life sciences, and space technology has made great contributions to the research of human life sciences. Used for the early 1990s, memory foam was once again developed as a civilian product, and was first widely promoted and applied in medical emergency and monitoring systems. Then it spread rapidly in developed countries, especially in health-conscious countries like Japan.

The memory foam material itself has many excellent characteristics, and the biggest advantage is called the slow rebound characteristic. It can effectively absorb the impact when lying on it. When lying on it, it feels like floating on the surface of the water or in the clouds, and the skin feels no pressure; also known as zero pressure, some people will have a “red mark” on a large area of ​​the body when they sleep, and use memory foam Materials will not. Memory deformation, using the body’s own heat to heat, causing material deformation, during use, it will fit the human body better than ordinary materials, bringing people a seamless experience. memory foam mattress sale  Anti-bacterial and anti-mite, slow-rebound sponge inhibits the growth of mold, repels the irritating odor caused by mold growth and growth, and becomes more prominent when there is sweat and saliva. Breathable and moisture-absorbing, since each cell unit is interconnected, it has excellent moisture-absorbing performance and is also breathable.

The most common use of memory foam is currently mainly used in household products, such as soft furniture such as pillows and mattresses. It is far ahead of other materials in performance, but it is not perfect. There are also problems such as high cost and poor heat dissipation. Therefore, some manufacturers will use gels with larger specific heat capacity to process memory foam materials to give memory foam materials that have poor heat dissipation properties with good thermal conductivity.

The toxic memory foam is a misunderstanding of the memory foam material. There is no relevant information to prove that the memory foam material is toxic to the human body. Moreover, memory foam has long been used in the home furnishing industry of various countries that value safety and health, and there has been no discomfort caused by the use of memory foam. Compared with the popular artificial latex with formaldehyde risk and allergy risk in China For natural latex, the material of memory foam is more environmentally friendly, safer and healthier.

So I hope this article can help you understand memory foam better, so that you can choose a more comfortable mattress that suits you when choosing a mattress.

How to choose a bottle for novice parents

After being a parent, I feel more and more that feeding children is not easy. Every baby is unique. No matter how successful the parents of other people’s families are, it is still necessary to take good care of their own children. To choose, here is a summary of several common types of milk bottles. You can choose one according to your own requirements.

Plastic baby bottle
Plastic baby bottles are the most common and the most popular on the market, because they are lightweight, hard to break, and cheap. It’s easy for mom and dad to hold it or take it out, and it’s very convenient for older babies to drink with their own bottles.
However, the plastic material is porous and easily absorbs odors and even bacteria, so it must be cleaned as soon as possible after use.
In addition, although most of the plastic baby bottles are BPA Free (without BPA), if the plastic is scratched, deformed, or discolored, harmful chemicals inside the plastic may be precipitated. In particular, parents often use boiling water or steam to sterilize plastic baby bottles. Prolonged exposure to high temperatures will make plastic materials more prone to problems. Therefore, parents who use plastic baby bottles should always check the condition of the baby bottles and replace them with new baby bottles when problems are found.

Glass bottle
Glass baby bottles are the most traditional baby bottles. Compared with plastic, glass is more environmentally friendly, can withstand high temperatures, does not precipitate harmful substances or odors, is easier to clean, is not easy to scratch, and is more durable under normal conditions.
However, the price of glass baby bottles is usually more expensive than plastic baby bottles, and is much heavier than plastic baby bottles. Mom and dad are easy to get tired when holding them, and it is not easy for babies to drink by themselves. In addition, if the glass baby bottle is accidentally dropped on the ground, it is easy to break, so when choosing a glass baby bottle, mom and dad should be equipped with a hand-slip and shatter-resistant cushioning protective rubber cover.

Stainless steel baby bottle
Stainless steel material can be regarded as a combination of the advantages of plastic and glass, moderate weight, environmentally friendly, durable, high temperature resistant, easy to clean, will not break, and will not precipitate harmful substances or odors. However, stainless steel is more expensive, and because it is opaque, it is difficult for parents who need to make milk powder to see the scale and grasp the quantity. On the other hand, studies have shown that breast milk stored in steel containers has a significant decrease in the number and cell viability of breast milk stored in plastic or glass containers. Therefore, if breastfeeding mothers choose to use stainless steel bottles, it is best not to leave breast milk in the bottle for too long.

Silicone baby bottle
Finally, there is a silicone milk bottle. The silicone material is as light as plastic, but it is not easy to scratch, easy to clean, and safer than plastic. Moreover, silica gel is soft. Squeezing the bottle slightly during feeding can also increase the flow rate of the milk. In addition to the soft silicone bottle body, its pacifier is designed to imitate the shape of a mother’s breast, and it is equipped with two air ducts that can reduce flatulence. silicone molds suppliers Because of the breastfeeding mode close to breastfeeding, it is easier to be accepted by breastfeeding babies and solves the problem. The problem of less breastmilk/bottle conversion, or mothers who want breastfeeding and bottle feeding at the same time.

I hope this article will be helpful for novice parents. Experienced parents are welcome to share their experience of using various bottles in the comments, and recommend more good things!
