They are 1. Austenitic stainless steel – austenite iron structure is stabilized when nickel is added with it. At low temperature such steel almost be low brittle and non magnetic due to this crystal structure. In stainless steel composition sufficient quantities of manganese has been added to preserves the austenitic structure in steel same as like nickel but cost is low. 2.
•The design of it produces drastically less jerking torque than more great traditional drills due to the fact the motor is geared in the direction of the pneumatic hammer. •The 1 and 1/8 inch of the rotary hammer product name refers back to the maximum diameter it spins. •This Bulldog Extreme Max is a more substantial choice that packs lots extra power with an progressed anti-vibration device that trumps other fashions. •Plus it has additionally progressed its heat dissipation talents, that means that it does not overheat as a great deal because of a plate placement that permits cooling and venting thru continuously forced air even as in operation. •Buyers say that it without problems punches thru concrete like a hot knife thru butter- with users, for instance, doing basement reworking drilling hundreds of holes to bust out concrete and 1/4-inch, three/eight-inch and half-inch hollow sizes.
For this reason gear is preferred over belt drive where constant velocity ratio is needed especially for precision machine. When friction between two tangentially mating wheels is sufficient the power transmitted is kinematically equivalent with the power transmitted by a pair of gears. For a mating tangential wheel, the driven wheel will rotate as long as driving wheel does not experience frictional force which exceeds
3.6 Competitive Position and industry attractiveness Garmco acquires arelatively low competitive position. This is because of their inability to compete with the Chinese manufacturers, the strength Alba has over them in increasing prices, the availability of substitutes especially in packaging and construction industry along with the aggressive competition worldwide. However, the aluminum industry apart from the high startup and fixed costs is attractive if the smelters entering have the capacity to enter and compete on a global scale especially with the Chinese
Therefore, we can use less force to lift a heavy object. There are many type of tools use created by this law of lever such as see-saws, crowbars, pliers etc. It is also applied in our body. One example is the joint between the head and the first vertebra. Another improvement is the changeable cutting edge.
Copper is widely used in the manufacture of important alloys such as brass and bronze. It is a ductile metal with very high thermal and electrical conductivity [6,7,8]. Deep drawing steel is more ductile than commercial quality and is suitable for producing deep drawn parts needing severe deformation. It is not as formable as the extra deep drawing steel, but it is less costly. This material offers more formability to produce parts with a moderate depth of draw .
• Drilling – it is the process used to create right circular cylinder by using a twist drill. It is one of the most common processes involved in machining operations. • Turning – It is a process by which a part of the material is removed outside the diameter by using a lathe machine. In this machine, the workpiece is kept stationary while the tool is rotated according to the required
Cost effectiveness only for soft rock is another criterion that this machine has.  some other pros of surface miners are the following: • less amount of stress and strain on trucks due to less impact of the excavated material. • Capacity for coal washing/preparation plant is reduced. The only drawback is the surface miners are used mostly in the extraction of coal, limestone and other soft to medium hard material. Cutting ability of surface miners depends on the unconfined compressive strength of rock which will be cut.
They also want to know if the alloy are better than other kinds of wheels. Alloy wheels are meant for the same function that normal wheels do, but there are some additional features which make the alloy wheels different and better than normal wheels. The normal wheels are made from steel, wherein the alloy wheels are made using magnesium or aluminum. This is why, alloy wheels are more duarble and stronger than steel wheels. In addition, alloy wheels are lightweight, stylish and better in terms of performance.
Based on the type of the metal which is being casted, either a hot chamber machine or a cold chamber machine can be used according to the task. The tools required for casting process and the metal dies stand for large amounts of capital expenses and this will tend to put limitations on the process against the production in a high volume. Manufacturing of different parts using the die casting system is comparatively much simpler, and it involves only four principal steps. This helps to keep the cost per item to a low level. It is particularly well matched for a huge amount of small to medium size castings.
