Different Tools in Engineering

Shearing machine:

The main concept of this machine is accurate and distortion-free shearing at desired angle. 

Uses:

A shearing machine for cutting the strip to remove damaged turns at the end of a coil and a coiler for coiling the strip after rolling. To avoid wastage of sheet, the shearing machine has a movable shearing head and is positioned adjacent the strip path between the uncoiled and the rolling mill. The shearing head is movable across the strip path to effect cutting of the strip.     

 Power press machine:

        By making use of qualitative raw material power press has been manufactured. These are widely demanded in processing industry.

• Fly Wheel

• Frame

• Ram Slide

• Stroke

• Break

• Power Required

• Applications

Shaping machine:

Shaping machine is a machine or a tool for shaping metal or wood                    

Uses:

A shaping machine is used to machine surfaces. It can cut curves, angles and many other shapes. It is a popular machine in a workshop because its movement is very simple although it can produce a variety of work.

Lathe machine:

         A lathe machine is a tool which spins the work piece to perform various operations such as cutting, sanding, knurling, drilling, or deformation with tools that are applied to the work piece to create an object which has symmetry about an axis of rotation.

Uses:

A lathe can be used to:

Turn an ornate wooden spindle

Skim a cylinder head or other gasket-face

Put a screw-thread on a piece of metal bar

Drill a hole of almost any size in almost any material

Machine an intricate valve, collect or gudgeon

Put a screw-thread INSIDE a hole (Tap the hole)

Welding machine:

     Welding machines are usually classified as constant current (CC) or constant voltage (CV); a constant current machine varies its output voltage to maintain a steady current while a constant voltage machine will fluctuate its output current to maintain a set voltage.     

Bench grinder:

            A bench grinder is a type of benchtop grinding machine. This machine uses abrasive wheels to grind metal or ceramics. Bench grinders are found in home workshops and industrial settings and are primarily used for sharpening and shaping.

Uses:

Use to drive abrasive wheels

Used to hand grind cutting tools and perform other rough grinding. [1]

Depending on the grade of the grinding wheel it may be used for sharpening cutting tools such as lathe tools or drill bits. Alternatively it may be used to roughly shape metal prior to welding or fitting.

Spot welding machine:

      Spot welding is a process in which contacting metal surfaces are joined by the heat obtained from resistance to electric current flow. Work-pieces are held together under pressure exerted by electrodes.

     The attractive feature of spot welding is a lot of energy can be delivered to the spot in a very short time (approximately ten milliseconds).[2] That permits the welding to occur without excessive heating to the rest of the sheet.

Uses:

It is mostly used when welding particular types of sheet metal.

            There are many different uses of spot welding machines. Some of the areas where

it finds application are:

• Automobile industry

• Automotive manufacturing

• Metal working

• Shipbuilding

• Fabrication

• Casting
