Types of lathe cutting tools

K-type cemented carbide by the tungsten carbide (WC) and cobalt (Co0 composition, bending strength and toughness, is used to process cast iron, hard bronze and other brittle materials or the impact of a large occasion. Low temperature (640 ° C or so) and steel friction, its wear resistance is poor.Therefore, can not cut steel, but difficult to machine in the cutting of materials or vibration of the larger special circumstances, due to the cutting speed is not high, Tool strength and toughness of the more prominent requirements, the use of K-type alloy more appropriate.
K-type alloy grades YG3, YG6, YG8, etc., the number of grades that the percentage of cobalt content, the rest of the carbide. Alloy containing more cobalt (such as YG8) its hardness is low, and good toughness, suitable for roughing. Cobalt less (such as YG3) its hardness, wear resistance and high heat resistance, suitable for finishing.
A variety of uses of the tool grinding method is not the same, in practice, continue to explore, in short, the brittle metal cutter angle small, tough mouth can be thicker, generally not grinding chip groove. Plastic metal to roll out the chip tank (also known as chip breaker) after the angle of the appropriate grinding to reduce friction.

The consequences of anabolic steroid abuse

The abuse of steroids can bring many side effects. It can cause acne, acne, male breast enlargement; serious life-threatening, such as heart and liver cancer. Most of the side effects can be reversed if stopped in time, but some side effects are permanent!
The vast majority of the data on the side effects of steroids on the human body comes from case reports. From these case reports can be seen steroids on human health hazards are not profoundly understood. From the animal study data, concluded: the use of steroids are not long life!
Steroids severely disrupt the body's hormonal system. Steroids seriously disrupt the body's normal production of hormones, causing irreversible or irreversible changes in the body. Reversible physical changes include the number of semen and testicular shrinkage; irreversible changes in the body, including the failure of male hormones and breast enlargement. In some male bodybuilders survey found that, because of their hormonal system is destroyed, most of the testicles are reduced and breast significantly increased; female bodybuilder survey found that they tend to masculine, mainly in the breast changes Small, body fat was significantly reduced, the skin becomes very rough, clitoris increased, the sound becomes low, increased body hair, hair less. If you continue to use, then, some side effects simply can not be saved!
Steroids severely disrupt the skeletal muscle system. Growing testosterone powder and other sex hormones can make a teen's body grow very fast. However, when the hormone to a certain level, it will stop the growth of bones, there will never be a change in height!

Leading Water Cooled Chillers Manufacturers & Suppliers in China

We all might have heard about the term Water cooled chillers or scroll chillers. But do we know what it actually is? The leading water cooled chiller manufacturer, AC+ explained here.
Chillers are cooled water air conditioning system that cools the air inside a space. This equipment can cool the water up to 6° C and is more efficient than the cooling tower. But its cost is higher.
The liquid chillers units or generators of ice water chiller are the ideal solutions to meet the needs of air conditioning in commercial buildings, hospitals, universities, hotels, government facilities, etc., as the cost of energy to generate cooling using other air conditioning systems on the same would be quite high. These teams have the advantage of bringing the chilled water to the CRAC at any distance by the suitable pump.
Uses and Applications of chillers
Some of the most common applications of chillers are: – The industry HVAC (heating, ventilation and air conditioning): A large scale air conditioning systems pump water cooled to serpentines in specific areas.
The water management systems for each area, open and close the water flow through specific areas keeping the air in the room at the desired temperature.
Cooling system works by Chillers
The chiller is placed on the outside of the building. Inside the building, the thermo-ventilated be placed units called fan coil which is similar to the indoor units of a direct expansion system. The only connections between the internal unit and external unit are a common hydraulic circuit closing a circuit.
The liquid treated in the outdoor unit cooled or heated and circulated by the pump included in the system, all fan coil units. Finally, the FAN-COIL uses water flowing through it, sending the resulting heat exchange (cold air or hot air), by a fan to the environment according to the demands of user comfort.
Advantages of Chillers
The main advantage of the chiller is being controlled electronically, provides water to the desired temperature more accurately, and the temperature can drop more water compared to other equipment such as cooling towers.
As a generally closed circuit, water pollutes less and this replacement is less due to no such loss by evaporation. Installation Is relatively small and generally chiller lot of pressure sensors, temperature, flow, voltage, current, which makes it very useful in terms of detecting problems in the system. Refcon chillers, reputed water cooled chiller suppliers says that “The application area of these devices is quite high and several industries use them for industrial and general applications. We provide a wide range of chillers for all kinds of needs at one place.”
