The principles of CNC operation. Movement of X, Y, Z axis are controlled by a motor which supplies either Alternating current or Direct current. Movement of the machine is done by giving commands. All the operations are carried out by codes like speed, feed, depth of cut, etc. For each operation separate code is available.
face. An automatic grinding and polishing machine is shown in Fig. 4.1. Automatic grinding methodsteps are: 1. Symmetrically load three to six mounted specimens into the specimen holder of an automatic grinding-polishing machine, with the flat sur-face of the ceramic section downward. Most manufacturers provide a
Inside diameter grinding, also called as internal grinding, is used for grinding the inner diameter of tubular object. Workpiece or object will have already drilled hole and internal grinding process will be performed to finish the inner surface of workpiece with the help of small grinding wheel rotating at higher revolution per minute.

Working Principles, Capabilities & More. In short, CNC machining is a metal fabrication method where written code controls the machinery in the manufacturing process. The code determines everything from the movement of the cutting head and the part to spindle speed, RPMs, etc. CNC machining services use a subtractive fabrication method.
The grinding machine provides high accuracy and fine surface finish with minimum tolerances. The machining process is done by the abrasive action of the grinding wheel; the abrasives are embedded over the periphery of the rotating wheel. In Grinding machine grinding wheel is work as a cutting tool and responsible for all machining processes.
Grinding Machine. A grinding is metal cutting operation which is performed by means of a rotating abrasive wheel that acts as a tool.; These are mostly used to finish workpieces which must show a high surface quality, accuracy of shape and dimension. Mostly, it is finishing operation because it removes material in very small size of chips 0.25 – 0.5 mm.

The working principle of electrochemical grinding is When a metal surface is acted upon with an electrolyte under a high current, the metal surface gets oxidized to form an oxide layer (corrosive layer). This layer is removed with the action of a flowing electrolyte and rotating grinding wheel.
5. Move the grinding wheel down using the vertical table handwheel until it barely makes contact with the dresser. 6. Turn the machine off after making contact with the dresser. 7. Turn the machine on again. While the wheel is spinning, lower the grinding wheel down in the Z direction until it makes a small plume of dust. 8.
In this machine, the workpiece metal is removed during the return stroke of the Ram. Hydraulic Shaper: In this type of machine, the reciprocating motion of the ram is provided by the hydraulic mechanism. This Hydraulic shaper uses the oil under high pressure and the end of the piston rod is connected to the ram.

Precision grinding machines, as with all production machines, are subject to wear. This means there must be a program of planned maintenance or checking for sustained quality and output. Some machine designs are less prone to the effects of wear than others are, and this can be an important consideration in machine selection.
Cylindrical Grinding Machine: Types, Process & Working Principle :-Cylindrical grinders are employed to slice or cut very precise and subtle finishes on materials such as aluminum, carbide, steel or other metals. They are especially used to work on cylindrical surfaces, rods or other cylindrical work pieces.
The principle of selecting a grinding wheel during operation should choose the most suitable grinding wheel with different workpiece materials and hardness. A thin oil film should be applied to the spindle end of the grinding machine and the flange of the grinding wheel to prevent the generation of rust.
The working of a grinding machine: A grinder features an electric motor that supplies motion power to the grinding wheel using pulley and belt. For the portable grinder, the rotor is inside the grinding machine and the power switch is located beside the handle of a grinder. So, the switch must be pressed before the grinder works.
