Types of Industrial machinery which enhances the efficiency and productivity by Jayesh K
Industrial machinery with its advancement in engineering are the tools used and applied in the industries and factories to enhance the proficiency and efficiency in terms of overall production.
A machine which cuts away knots and loose yarn ends from the surface of cloth after it has been woven, to give the cloth a smooth surface.
A machine press, commonly shortened to press, is a machine tool that changes the shape of a work piece
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.
The shaping machine is used to machine flat metal surfaces especially where a large amount of metal has to be removed. Other machines such as milling machines are much more expensive and are more suited to removing smaller amounts of metal, very accurately. The cutting tool removes the metal from work which is carefully bolted down.
The shaping machine is a simple and yet extremely effective machine. It is used to remove material, usually metals such as steel or aluminum, to produce a flat surface. However, it can also be used to manufacture gears such as rack and pinion systems and other complex shapes. Inside its shell/casing is a crank and slider mechanism that pushes the cutting tool forward and returns it to its original position.
A lathe is a machine 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.
Examples of objects that can be produced on a lathe include candlestick holders, cue sticks, table legs, bowls, baseball bats, musical instruments (especially woodwind instruments), crankshafts and camshafts.
A welding power supply is a device that provides an electric current to perform welding. Welding usually requires high current (over 80 amperes) and it can need above 12,000 amps in spot welding. Low current can also be used; welding two razor blades together at 5 amps with gas tungsten arc welding is a good example. A welding power supply can be as simple as a car battery and as sophisticated as a modern machine based on silicon controlled rectifier technology with additional logic to assist in the welding process.
A bench grinder is a type of bench top grinding machine used to drive abrasive wheels. A pedestal grinder is a larger version of a bench grinder that is mounted on a pedestal, which is bolted to the floor. These types of grinders are commonly used to hand grind cutting tools and perform other rough grinding.
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.
Press brake machine:
A press brake is a special type of machine press that bends sheet metal into shape. A good example of the type of work a press brake can do is the backplate of a computer case. Other examples include brackets, frame pieces and electronic enclosures just to name a few. Some press brakes have CNC controls and can form parts with accuracy to a fraction of a millimetre. Bending forces can exceed 4,000 kilonewtons (900,000 lbf)
Automated perforated punching machine:
Automatic Paper Punching Machines.Paper punch for automatic and continuous punching of each binding perforation for loose leaf binding, such as spiral binding, double wire binding, plastic comb binding, filing hole systems and other edge perforations. It is composed of compactness and heavy duty construction to punch paper, cardboard and mixed material.
