Brazing

It is the process of joining metals by heating base metals at a temperature of 800°F after which a nonferrous filler metal with a melting point well below the base metal is added to form a strong joint by capillary action. When brazing is done, flux is used as it prevents the oxide formation while the metal is heated.

The Gas Turbine Engine for cars

The turbine engine has been independently researched and developed by most of the major car manufacturers including Rover , Fiat , General Motors and Chrysler. The working of a turbine engine is simple compared to that of an IC reciprocating engine . Basically it involves the pulling in and compressing of air to the engine in relatively large quantities and then expanding this air and using it to drive a power turbine. The power turbine is connected by a common shaft to the compressor turbine . About 10% of the power generated is used to turn the compressor turbine

Single Slider Crank Chain

A single slider crank chain is a modification of the basic four bar chain. It consist of one sliding pair and three turning pairs. It is,usually, found in reciprocating steam engine mechanism. This type of mechanism converts rotary motion into reciprocating motion and vice-versa.

Significance of Ball Screws in Machine tool industry

Ball screws are a highly efficient way of converting rotary to linear motion.

This is due to the ball screw's high reliability, precision and efficiency compared to more traditional power transmission components such as belt or chain drives, which we also distribute

WHY PETROL ENGINES ARE MORE POWERFUL THAN DIESEL ENGINES FOR THE SAME CUBIC CAPACITY?

Due to greater compression ratios and higher burning temperatures the diesel engine has a thermodynamic cycle that is basically more efficient than that of the gasoline engine. Then it uses less fuel per unit of power produced, but in order to do this it needs more space inside the cylinders to make the best 

Heavy construction equipment

Excavators are heavy construction equipment consisting of a boom, stick, bucket and cab on a rotating platform (known as the "house"). The house sits atop an undercarriage with tracks or wheels. A cable-operated excavator uses winches and steel ropes to accomplish the movements. They are a natural progression from the steam shovels and often called power shovels. All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid, with hydraulic cylinders and hydraulic motors. Due to the linear actuation of hydraulic cylinders, their mode of operation is fundamentally different from cable-operated excavators.

Laser Beam Machining (LBM)

It removes, melts, or thermally modifies a material by focusing a coherent beam of monochromatic light on the workpiece. The LBM process does not involve mass material removal, but does provide rapid material removal with an easily controlled, non-contact, nonwearing tool. The LBM process also places minimal demands on workpiece fixturing in cutting operations and performs a variety of other metal processing functions such as drilling, welding, marking, and heat treating

First law of thermodynamics

The first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic systems. The internal energy of an isolated system is constant and energy can be transformed from one form to another, but cannot be created or destroyed. The first law is often formulated by stating that the change in the internal energy of a closed system is equal to the amount of heat supplied to the system, minus the amount of work done by the system on its surroundings.

Electrochemical machining (ECM)

It is a method of removing metal by an electrochemical process. It is normally used for mass production and is used for working extremely hard materials or materials that are difficult to machine using conventional methods. Its use is limited to electrically conductive materials. ECM can cut small or odd-shaped angles, intricate contours or cavities in hard and exotic metals, such as titanium aluminides, Inconel, Waspaloy, and high nickel, cobalt, and rhenium alloys. Both external and internal geometries can be machined.

ECM is often characterized as "reverse electroplating," in that it removes material instead of adding it.

hydropower plants

Dam - Most hydropower plants rely on a dam that holds back water, creating a large reservoir. Often, this reservoir is used as a recreational lake, such as Lake Roosevelt at the Grand Coulee Dam in Washington State.
Intake - Gates on the dam open and gravity pulls the water through the penstock, a pipeline that leads to the turbine. Water builds up pressure as it flows through this pipe.
Turbine - The water strikes and turns the large blades of a turbine, which is attached to a generator above it by way of a shaft. The most common type of turbine for hydropower plants is the Francis Turbine, which looks like a big disc with curved blades. A turbine can weigh as much as 172 tons and turn at a rate of 90 revolutions per minute (rpm), according to the Foundation for Water & Energy Education (FWEE).
Generators - As the turbine blades turn, so do a series of magnets inside the generator. Giant magnets rotate past copper coils, producing alternating current (AC) by moving electrons. (You'll learn more about how the generator works later.)
Transformer - The transformer inside the powerhouse takes the AC and converts it to higher-voltage current.
Power lines - Out of every power plant come four wires: the three phases of power being produced simultaneously plus a neutral or ground common to all three. (Read How Power Distribution Grids Work to learn more about power line transmission.)
Outflow - Used water is carried through pipelines, called tailraces, and re-enters the river downstream.
The water in the reservoir is considered stored energy. When the gates open, the water flowing through the penstock becomes kinetic energy because it's in motion. The amount of electricity that is generated is determined by several factors. Two of those factors are the volume of water flow and the amount of hydraulic head. The head refers to the distance between the water surface and the turbines. As the head and flow increase, so does the electricity generated. The head is usually dependent upon the amount of water in the reservoir

Annealing process

Annealing

It is a heat treatment process done to induce ductility in the metal. Material is heated above its recrystallization temperature and then it is cooled down which relieves its internal stresses and refines the structure.

A special link on a chain that can be opened by flexing a plate, removing a screw, or some other means besides driving out a rivet. This allows a convenient way of separating the chain
