Working principle of grinding machine Generally, in a grinding machine, the grinding wheel is mounted on the spindle which is driven by an electric motor. During the process, a high speed revolving grinding wheel is brought in contact with the workpiece.
The abrasive grains on the ECG wheel serve three major purposes: 1. Act to wipe the oxide from the workpiece, exposing new metal and allowing the process to continue. 2. Spacer to keep the conductive media in the wheel from making direct contact with the workpiece and generating a short circuit. 3.

Forging Process Definition: Forging is a Metal Forming Process in which the workpiece is heated to higher temperatures and is placed on the die (work region). Now, a large amount of compressive force is applied to the workpiece with either similar die or hammers in a vertical direction so that the shape change (deformation) takes place.
Working Principle of Cylindrical Grinding Machine Within this machine, the workpiece is rotated between two centers on its axis. From a high-speed rotation, the grinding wheel grinds the two centers on its axis so as to produce a smooth surface. Parts of Cylindrical Grinding Machine There are following parts are used: Base Wheel Head
Working Principle of Drilling Machine: When the power is given to the motor, the spindle rotates, and thereby the stepped pulley attached to it also rotates. On the other end, one more stepped pulley is attached and that is inverted to increase or decrease the speed of the rotational motion.

As in the planer machine, the worktable is a movable part and the tool is a fixed part, therefore the worktable can be run by means of a hydraulic cylinder or by a pinion-gear mechanism. The upper surface of the worktable has T slots for clamping the workpiece and the sides of the worktable have a groove for planer reversing dogs.
A CNC machine tool always has a sliding table and a spindle to control the position and speed. The table of the machine is controlled in the X and Y-axis direction and the spindle is controlled in the Z-axis direction. 4. Driving System: The driving system of a CNC machine include of an amplifier circuit, drive motors, and ball lead screws.
There are basically two types of cylindrical grinding Process-. 1. External Cylindrical Grinding. External cylindrical grinding is very common grinding processes. This grinding is mainly employed for grinding rotationally symmetrical work pieces. There are different methods of external cylindrical grinding depending upon the type of work piece ...

From the diagram you can see that the beta angle is more than the alpha. So we can say that cutting strokes takes more time than returning strokes. Applications of Quick Return Mechanism: These are the following applications of Quick return mechanism: It is used in the shaper Machine for flattening the workpiece.
grinding machines, bufting machines. and reciprocating surface grinding machines. UTILITY GRINDING MACHINES The utility grinding machine is intended for offhand grinding where the workpiece is supported in the hand and brought to bear against the rotating grinding abrasive wheel. The accuracy of this type of grinding machine depends on the ...

Threading Working Principle of ultrasonic Machining: It consists of an electromechanical transducer connected to the AC supply. Velocity transformer which holds the tool firmly. An abrasive gun is used to supply an abrasive slurry, which is a mixture of abrasive grain and the water in between tool-workpiece interface under a definite pressure.
Chucking type internal grinder. Figure 29.16 illustrates schematically this machine and various motions required for grinding action. The workpiece is usually mounted in a chuck. A magnetic face plate can also be used. A small grinding wheel performs the necessary grinding with its peripheral surface.

1. Base: It gives support and rigidity to the machine and also acts as a reservoir for the cutting fluids. 2. Column: The column is the main supporting frame mounted vertically on the base. The column is box shaped, heavily ribbed inside and houses all the driving mechanisms for the spindle and table feed. 3.
WORKING PRINCIPLE PNEUMATIC CIRCUIT: Fig: Pneumatic circuit Since pneumatic circuit plays a vital role in this device, it is very necessary to explain the working of this circuit. Initially starting with air compresses, its function is to compress air from a low inlet pressure (usually atmospheric) to a higher-pressure level.
Types of Boring Machine These are the following types of boring machine:- 1. Table type boring machine 2. Floor type boring machine 3. Precision boring machine 4. Planer type boring machine 5. Multiple head type boring machine 6. Vertical turret lathe boring machine 7. Standard vertical boring machine 8. Vertical milling machine type boring machine
A combination of the cutting pressure and capability of the grinding wheel and the gravity acting on the workpiece ensures that the work maintains contact with the control wheel and the rest blade. The control wheel (or regulating wheel) is normally made from a rubber bonded material that offers a frictional surface that is constantly advancing.
The working principle is that cement is removed from the mill before over-grinding has taken place. The cement is then separated into a fine fraction, which meets finished product requirements, and a coarse fraction which is returned to mill inlet. Recirculation factor, that is, the ratio of mill throughput to fresh feed is up to three.
Milling Machine Definition: The milling machine is a type of machine which removes the material from the workpiece by feeding the work past a rotating multipoint cutter.The metal removal rate is higher very high as the cutter has a high speed and many cutting edges. It is the most important machine in the tool room as nearly all the operations can be performed on it with high accuracy.
Centerless grinding differs from centered grinding operations in that no spindle or fixture is used to locate and secure the workpiece;  the workpiece is secured between two rotary grinding wheels, and the speed of their rotation relative to each other determines the rate at which material is removed from the workpiece. 
This design provides the kinematic arrangement of forces, materials selection and proportion of parts to ensure maximum strength and functionality of the machine. To avoid failure of the...
Grinding this part reduces the intensity of the friction it will be subjected to. The shaft therefore becomes more durable and reliable. Cylindrical grinding is also used in areas with particularly high technical requirements. Many industrial machines have ground parts, as do the vast majority of engines.
Special types of grinders are grinding machines made for specific types of work and operations, for example: Tool and cutter grinders. These grinding machines are designed to sharpen milling cutters, reamers, taps and other machine tool cutters. The general-purpose cutter grinder is the most popular and versatile tool-grinding machine.
