Steel fabrication is a complicated process. There are different types of steel alloys that are described in the market and they’re different in composition and nature. Therefore, when you’re talking about the steel fabrication, you’re actually thinking about a range of options. Often, the austenitic stainless steel is regarded as the best option because it has the higher work harden rate and therefore, it can be really useful. Also, this alloy has less sulphur and other non metallic elements that thereby, this is ideal option to be employed in the corrosive atmosphere. machine tool orders -rush order and quotes.
However, one of the problems associated with the austenitic steel is that it isn’t suitable for machines. Well, there are free machine versions of this alloy available in the market. But, there are some problems with these versions. First of all, these versions have higher amount of sulphur in them. Therefore, they just become more corrosive. Also, the high amount of sulphur makes these versions difficult to be used in tight radius situations.
So, what does that mean?
Anyways, a welcome alternative has come out of late. This is called the improved machinability. The version includes the 304 and 316 Grades. The good thing with this version is that it’s manufactured by proprietary steel melting technologies. There is enough chip breaking features that improve the machinability of the steel considerably, as a result. At the same time, they retain the good qualifications of the austenitic steel. Therefore, you can still weld these alloys, and they’re considerably corrosion resistant. This version is initiated in the market with different names. However, they have 20% better machine speed which is still a considerable improvement. AVSmachineandtool.com – quotes for custom machine work.
The next important point is the difficulty of machining the alloy. Generally, the austenitic stainless steel is a problem for the majority of operators. In fact, the difficulty of using machine on this type has given rise to the grade 303 which is a free machine version. Well, there are plenty of similar options for the martensitic and Ferritic steels as well. In most of the cases, these machine free versions include manganese sulphide. They act as the chip breakers and thereby improve the outcome of using machines on them.
However, one must note in this respect, that the free machine grades have low corrosion resistance when in relation to the other versions. This is because these versions include non metallic elements in them and therefore, these alloys should never be used in corrosive environment like marine exposure. Also, the free machine grades have high level of sulphur that reduces the ductility of the alloy. So, you cannot bend them around a tight radius. They also become very difficult to weld. So, they shouldn’t be chosen for welded fabrication as well.
Anyways, machining the stainless steel is very important in the case of achieving the type of effect that you want to include in your fabrication. So, there are several techniques that the professionals must follow to make sure that the machining produces something strong, useful and aesthetically pleasing. For that, they generally follow a number of the rules.
CNC Machine shop: The CNC milling department has state of the art technology. It can machine any machinable material like stainless steel, carbon steels, alloy steels, delrin, G10, polycarbonate and nylon, ABS, and the likes. CNC machining uses only the best software program and high-end equipment.
The most important factor which they are required to check out is that the means that they’re using is firm and in working condition. They shouldn’t create vibration and the tip of the machine should be sharp. The operators is required to ensure that the blades are sharpened as soon as the sign of blunt edges are identified. Grinded wheels too, should be carefully maintained. Ideally, the professionals should use large tools as that will dissipate the heat. The tool shouldn’t keep on rubbing the work and constant feeds must be provided.
The plasma cutting process includes the consumption of a plasma torch to cut metals and steel of different thickness. Plasma cutters have become very popular in the world as an excellent tool for metal cutting. This wide popularity has resulted in various manufacturers conducting extensive research to enhance the functionality of the plasma cutters. Hypertherm plasma cutters is the results of this research, and includes all the characteristics of an advanced plasma cutting device. home machining and tooling.
Scientists have proved that aside from the three states of matter which are known to them, namely solid, gas, and liquid, there is a fourth type known as plasma. It doesn’t exist naturally on earth. When a gas is heated to very high temperature, tremendous amount of energy is moved to the atoms which ionize into its basic components, nuclei and electrons. Plasma is known to be an excellent electric conductor.
Adding to this discussion.
Plasma cutters work by passing a gas through a narrow opening and bringing this in contact with an electric arc. The gas used can be nitrogen, oxygen, compressed, or argon air. This causes the temperature of the gas to rise astronomically resulting in the manufacture of plasma. This high energy released is passed to the metal under operation by the electrical conductivity property of plasma. Since the plasma is essentially a fluid, it has the potential to clear the metal surface free of the residue produced from the cut.
The main drawback of conventional gas cutters were that they weren’t able to cut metals with good conductivity. This disadvantage has been overcome with the new plasma cutter. The cutter can be used in order to cut mild steel, aluminum, copper, cast iron, and stainless steel. Therefore they it is widely employed in industries where such operations are involved.
The new plasma cutters are relatively cheaper than conventional gas cutters which gives them preference over the older type of cutters. They have the advantage of being user friendly and ensure economic advantages like minimized energy consumption. Since they don’t require flammable constituents, the risk factor involved is much lesser. They can be operated on electric power or gas. There are cases where Nitrogen or highly pressurized air can be used.
Plasma cutters are considered to be more effective than traditional oxy fuel cutters because they complement the work quickly and efficiently. Plasma cutters generate heat which is about 22000 degrees whereas the oxy fuels generate a mere 3150 degree Celsius. They can easily burn through most surface coatings such as paint and rust and still impart excellent cutting results.
Easy on the pocket, plasma cutters are more economical. Plasma cutting costs are about half than that of the oxy fuel.
It is important to have an idea how thick the metal is that you are going to cut with the equipment. The thickness of the metal will play a direct affect on the extent of the equipment required. For operations where cutting thin metals are involved, a smaller machine will be sufficient whereas to cut thick metals, heavier equipment is required.
Vitamin a is the first vitamin that was found by the doctors and that’s why it is named with the first letter of the alphabet. It is really important for the skin, hair, teeth, bones and good sight. Without enough vitamin A human organism is prone to infections.

What is it??
During the first trimester of the pregnancy, a woman experiences episodes of nausea and vomiting which are collectively known as morning sickness. It may also be known as emesis gravidarum.
What is the cause?
the causes include:
- High estrogen levels
- Low blood sugar
- Increased progesterone levels in the blood (may cause gastroesophageal reflux)
- Increased levels of HCG (hormone) which may stimulate estrogen release
- Increased bilirubin levels
- Increased sensitivity to odors
It is absolutely normal to have morning sickness and it causes no harm to the mother or baby unless too severe. No metabolic derangements are seen.
Most of the people call this condition as the first sign of pregnancy.
What will you experience?
Most of the women report that they are unable to enjoy sensory stimuli related to vision, taste, smell and touch.
A morning sickness may present at any time of day and not only specifically morning.
A few women may lose pounds and become dehydrated.
The condition usually improves as the pregnancy progresses.
No medical is required treatment is required if the condition is normal.
What should be done:
- Smaller meals should be taken
- Weak tea and biscuits to kill cravings
- Drink loads of water (up to 6-8 glasses per day)
- Eat when hungry only
- Do not skip meals and don’t keep yourself starving
- Ginger tea or a lemonade may be a good as drinks
Morning sickness is considered to be a kind of defense mechanism, which protects the fetus against any toxins that have been ingested by the mother.
What is sickle cell anemia??
Normal red blood cells have a biconcave shape that guarantees their pliability. The human body has blood vessels of different diameters; and the pliability with a biconcave shape of an RBC, makes it easy for them to pass through the narrowest vessels (like capillaries with a diameter less than an RBC itself) easily.
Sickle cell disease is a disease of RBCs that gives them the shape of a sickle. This debilitating genetic disease renders the sufferer with RBCs of crescent shape that lose their flexibility and become sticky and stiff.
Usually, even the affected people carry normal RBCs in their blood. As the normal oxygen concentration of the body falls due to certain reasons (e.g moving towards high altitude), the blood cells lose their normal shape and resemble a crescent.
So why do RBCs acquire a crescent shape? It’s because they have a defective hemoglobin which in low levels of oxygen forms solid chains in RBC that resemble a crescent with poor oxygen carrying and circulating ability.
The disease comes when both the parents give their defective genes to the offspring. One defective gene will only give what’s called a “sickle cell trait”
Signs and symptoms:
– Anemia (with associated symptoms)
– Delayed growth
– Vision problems
– Enlarged spleen
– Frequent infections
– Severe sudden abdominal pain
– Hand and feet swelling
– Shortness of breadth
The sickle cells block blood vessels and cause decreased blood flow which means damage, to the organ.
Mainly, oxygen therapy.
Hydroxyurea- a drug that stimulates production of fetal hemoglobin prevents sickling.
Pain killers and antibiotics.
A bone marrow transplant may also work.
Teenagers especially girls are always very conscious about their weight and shape which is why, eating disorders are quite common among them. Statistics show a very high rate of occurrence of anorexia nervosa, which is a mental eating disorder in juvenile women.
How is anorexia represented?
Anorexia shows the following manifestations:
Extreme loss of weight
Severe loss of appetite
Imagine a girl with anorexia. You will see a very lean person who has lost considerable amount of weight but still considers herself overweight. She is in a self-starvation state an because of this, the body has started using her body fat as a source of energy.
Just like this girl who is suffering from anorexia, anorexia patients show the following symptoms:
• Many pounds of weight is lost
• The patient fails to maintain the weight that is ideal for them
• The patient is afraid of gaining weight
• The patient becomes weak and very lean
• The patient assumes themselves as overweight and becomes sad on this thought
• They become sadder and feel bad about themselves because the way they look affects how they feel.
How anorexia nervosa affects the body?
Think of your body getting no nutrient from diet because you are not eating as much as you should. What will happen? The body has to get energy and nutrient from somewhere and so it starts breaking down your fat stores. So in this energy saving mode, the normal functions of the body are hampered. That person comes with:
Slow pulse rate
Low Blood Pressure
Loss of muscles
Getting easily fatigued
If you see any person around you with this eating disorder, you should report this to a doctor immediately.
The signs and symptoms of hepatitis B could range from mild to severe depending on the severity of the disease and the time of exposure or infection by the hepatitis virus. These symptoms could appear in about a couple of months after exposure to the infection. These are some of the signs and symptoms of hepatitis B virus;
Abdominal pain; this is usually one of the accompanying signs and symptom of the disease and the pain intensity could from mild to severe abdominal pain.
Dark urine; the urine color usually gets darker in the course of the infection which, is one of the signs and symptoms of the disease.
Loss of appetite; anorexia is another symptom as a result of hepatitis B infection.
Nausea and vomiting; Nausea is another accompanying symptom that could be accompanied by vomiting.
Generalized body weakness and fatigue; as a result of this infection, the human body becomes very weak and malaise would follow.
Jaundice; at severe cases your skin gets yellow and the whites of your eyes get yellow as well.
Sometimes you will never see any visible symptoms and could only be detected via some blood tests.
Chronic hepatitis is a progressive disease that could cause hardening of the liver cirrhosis and if not treated liver cancer could occur. So it is very important for one to know and be able to recognize the signs and symptoms of the same such that early detection and interventions could be facilitated.
Summer is just about here and families are beginning to head outdoors for sports, hiking, swimming and of course, picnics! Whether it’s a simple family picnic at the park or a romantic event for two there is something magical about finding that perfect spot underneath a shady tree, spreading out the blanket and enjoying a meal outside with a nice cool breeze, the sounds of children playing and your bare feet in the grass.
Enjoy the outdoors this summer safely by making sure that your picnic foods are kept cold and properly stored. Food left out, particularly foods containing mayonnaise can spoil quickly, resulting in food poisoning, which is no fun at all. When bringing home leftovers be aware that if the ice you kept your food cold with is melted, the food should not be eaten and should be thrown away.
Make sure you pack sunscreen and a first aid kit if you are going to be trekking anywhere and possibly insect repellent. Stay hydrated by drinking plenty of water and remember to keep any fruit juices cold and out of the sun. Better yet, freeze them; they will stay cold longer and help keep other foods chilled.
Avoid sticky, messy foods if possible, they attract bees and create more cleanup. Opt for low-mess finger foods and sweets that won’t melt or go bad quickly. Opt for lightweight cutlery and containers, especially if you have to hike to where you are going. While picnic baskets look nice they are bulky and heavy, try using insulated totes that can fold up after you are done with them. Don’t bring too much food; you don’t want to have to carry it back!
With a little planning and imagination, you can enjoy the perfect outdoor feast, creating fond summer memories for you and your family.
One question I hear a lot of new parents ask is when they should start feeding their baby solid foods. There seems to be conflicting information depending on what generation you are posing that question too. My Mother insists that I had to start eating solid foods by the time I was two months old because the bottle was not enough for me. I had similar advice from other Moms in that age group, that solid foods should start being introduced at two to four months old or the baby would be hungry and not get enough calories.
On the opposite end of the spectrum were Moms that insisted a baby has no need for solid foods until at least nine months of age and that it should be put off for as long as possible, and that starting solids too early could cause obesity and food allergies. Talk about confusing! Of course I asked my pediatrician for the answer and was told that four to six months is a reasonable time to introduce solid foods to a baby. Some babies are ready for food earlier than others.
If your baby is showing interest in what you are eating and is able to take a bite without pushing the food out with his or her toungue and has doubled birthweight then it is probably time to start solid food.
Families are busier today than ever before, whether both parents are working or a single parent family, not to mention afterschool sports and other activities, life is hectic. It seems there are just not enough hours in the day to get everything done. Corners are often cut and one of the things that suffer is mealtime. Eating is no longer the leisurelysit down event that it once was. Often times a family will go days or even weeks without sitting down and eating together. Some families schedules are so conflicting that they have done away with the family meal altogether. Even when families do manage to sit down and eat a meal together, there are often distractions such as the television, phones ringing or texting. It can be hard to connect and focus on one another.
Research has shown that families who share regular meals together report feeling closer and more connected. Children of families who have sit down meals together throughout the week get better grades in school and have fewer problems such as drug use and depression. It may be hard to believe that such a simple thing as just sitting down and eating dinner together a few times a week can have such an impact but it has been shown that it does.
If you are in the habit of eating on the run, or in front of the television you may want to consider a mealtime makeover. Sit down with your schedule and see if you can find an hour or two a couple times a week where everyone is home and can eat a meal together. It does not even have to be dinner, it can just as easily be breakfast or lunch. If your children are gone at sports or other activities every single night you might want to consider the fact that they are overscheduled. It may not seem like it, but simple, quality time with their parents is more important than participating in every extracurricular activity possible. Look in to the option of scaling down and slowing down.
Your first few family meals may feel awkward at first, even tense. This will pass as your family gets in the habit of doing it. If you can enlist your children in the meal preparations, so much the better. The kids may resist at first (and so might you) but keep at it. The benefits of this simple activity are proven. It doesn’t cost extra money or anything fancy. It doesn’t matter what the meal is, what matters is that your family is together in one place at one time.
