Sensitive Drilling Machine Working Principle | Diagram and Parts |

Here, You will see about  sensitive drilling machine and working principle of sensitive drilling machine and today i clear your all doubt about this topic so, Just start reading from with full concentration. All information you will get about sensitive drilling machine. Sensitive Drilling Machine  Most drilling work is carried out on column drilling machines, so-called because the machine elements are arranged in a vertical column. Machines in the heavy duty range are powered, driven from the motor through a gear box, and have a steel drilling capacity of up to 50 mm in diameter. The smaller sensitive machines, shown in the figure below, have manual feed, which gives you sensitivity, are belt driven from the motor via pulleys, and have a maximum drilling capacity in steel that varies from 5 mm to 25 mm diameter. These machines can be bench or floor mounted Diagram and parts of sensitive drilling machine  Diagram of sensitive drilling machine and parts of sensitive drilling machine are

Hacksaw | Types of Hacksaw Blades | Definition and Uses |

We will see about  hacksaw used for which purpose and  hacksaw definition and uses So without wasting any more time move towards our topic.I already write about engineers files and types of files . you should have idea about this it will help you to enhance your knowledge about workshop technology. The hacksaw hacksaw is generally used for cutting of metals.Where large amounts of metal waste must be  removed, this is done more easily by hack sawing away from extra metal rather than by depositing. Hacksaw Definition  hacksaw is a hand tool which is used for cutting of metal. Construction and working of hacksaw If the work-piece is left a little too large, then a file can be used to obtain the final size and surface. The hacksaw blade fits into a hacksaw frame on two holding pins, one of which is adjustable to tension the blade. The frame of the hacksaw should be rigid, keep the blade in correct alignment, stretch the blade easily and have a comfortable grip.The blade is mounted on the

Engineers Files Explained | Types of file

Today we will learn about engineers files explained, as we know hand tools are used to remove small amounts of material, usually from small areas of the workpiece.   Do you know why hand tools are used ?Hand tools are used because of following reason: If no machine is available,  The workpiece is too large to go on a machine  The shape is too intricate or simply that it would be too expensive to set up a machine to do the work. As you know the necessity of a hand tools now we will know about a hand tool , engineer's files. Engineer’s files Files are used to perform a variety of tasks, from simple removal of sharp edges to producing complex shapes where use of the device is impractical.Files can be obtained in a variety of shapes and in lengths from 150 mm to 350 mm. Single-cut file: When a file has a single series of teeth cut across its face it is called  single-cut file ,Figure of single-cut file is shown below. double-cut file: When a file has double series of teeth cut across

Auxiliary Views | Drawing, Examples,Definition

Auxiliary Views An auxiliary view is one projected from the front elevation (not in the positions occupied by the side elevation or the plan) to illustrate more clearly some important feature not seen in the other views. It so happens that the important feature is usually a face whose true shape is required. Definition of auxiliary Views An auxiliary view is a views which is form from the front elevation is shown to illustrate some important features not seen in other scenes more clearly. Examples of auxiliary Views Example of auxiliary views is shown by the given figure of  Auxiliary Views and Projected True Shapes. A auxiliary View and True Shape. Difficult Auxiliary View and True Shape. A auxiliary Views and Projected True Shapes. To explain this point more fully let us first draw the front elevation, plan and side elevation to dimensions shown in given figure.  An auxiliary view can be projected from any viewpoint. However, the "true shape" of the sloping face can only be

Biasing of p–n Junction | Forward and Reverse-biased |

Biasing the p-n junction means applying some external voltage to both sides of the p-n junction. Reverse-biased junction and forward-biased junction are two types of biased junction. You should have also good understanding of  N-Type and P-Type Semiconductor before moving towards this topic. Biasing of p–n Junction  Biasing of a p–n junction  means uses of some external voltage across the two sides of the p–n junction. It is divided into two groups  Forward-biased junction :  When the p-side of junction  is connected to the positive terminal of a battery and the n-side of junction is connected to the negative terminal, the p–n junction is said to be a forward-biased junction.  Reverse-biased junction  :If the positive terminal of the battery is connected to the n-side of junction and the negative terminal on the p-side, the p–n junction is said to be a reverse-biased junction. Now we will see about forward and reverse-biased junction in detail.  Related Topic    Bonding in semiconduc

About N-Type and P-Type Semiconductor | Materials | Example |

Here you will know about  n type and p type semiconductor in details. You can already see about bonding in semiconductor . N type and P type semiconductor is used in electronic appliances.which is the basis of working of all the electronic devices.So lets discuss in this given topic in the details. N type and P Type Semiconductor When some impurities added to the pure semiconductor then it becomes extrinsic semiconductor and this process of adding impurities is known as doping.  Now it depends on the which type of impurities it added to the semiconductor (two types of impurities can be added to semiconductor pentavalent or trivalent). n-type semiconductor : If impurity that is added to the pure semiconductor is a pentavalent ( which has five valance electron ) then it is called n-type semi conductor. p-type semiconductor : If trivalent impurity is added to the semiconductor then it becomes p-type semi conductor. ( Note-List of  n type and p type semiconductor material is given below.

Bonding in semiconductors,Bond model

Today we will see about Bonding in semiconductors or Bond model of semiconductor . A semiconductor atom that has four valence electrons and four holes requires four more electrons to completely fill the outermost orbit (the total number must be eight). Atoms in a crystal they are arranged so closely that the electrons orbit in valence layers of two atoms. Each valence shell electron fills the hole of the neighboring atom as shown in the given figure. A semiconductor have how many valance electron ? A semiconductor has need of four valence electron ans also require four holes to complete outer most orbit. Bonding in semiconductors or Bond model  In the given figure, the atoms of the silicon material is shown. For simple understanding, only the outermost orbitals of atoms are shown. The exchange of electrons from neighboring atoms to satisfy the requirement of eight electrons in the valence shell on one atom is called a covalent bond. Due to the covalent bond, that is, the b
