Combination Square Set:

 Combination Square Set


The combination square set is employed for layout operations. The set consists of a blade (graduated rule), square head, protractor, and center head.

Parts of Combination Square Set:

Following are the main parts of Combination Square Set:

1.    Blade
2.    Square Head
3.    Center Head
4.    Protractor Head

Blade:

 The blade is meant to permit the various heads to slip along the blade and be clamped at any desired location. The groove within the blade is concave to eliminate dirt build up and permit a free and straightforward slide for the heads. By removing all the heads, the blade could also be used alone as a rule.

Square Head:

 The square head is meant with a 45° and 90° edge, which makes it possible to be used as a square and miter square. By extending the blade below the square, it is often used as a depth rule. The square head also can be used as A level.

Center Head:

The center head, when inserted on the blade, is employed to locate and lay out the middle of cylindrical workplaces.

Protractor Head:

The protractor head is provided with a revolving turret graduated in degrees from 0 to 180 or to 90 in either direction. It is wont to measure or lay out angles to an accuracy of 1°.

Vernier Caliper and Its Parts:   Vernier Caliper Vernier Caliper: The vernier caliper is a measuring tool wont to get precise linear dimension measurements. A vernier micrometer is particularly useful to live the diameter of cylindrical objects as its jaws can clamp either side to urge accurate measurements. Main Parts of a Vernier caliper:   1. Upper Jaws or Inside Jaws   2. Lower Jaws or Outside Jaws 3. Depth Rod   4. Main Scale 5. Vernier Scale 6. Lock Screw 7. Thumb Screw 1. Upper Jaws or Inside Jaws: The upper jaws are smaller in size and are attached to the upper portion of the vernier micrometer. Similar to the lower jaws, one of these jaws is fixed and the other is movable. The difference between them and the lower jaws is that the upper jaws are used for measuring inside dimensions of hollow objects such as inside diameters of pipes, lengths and widths of boxes etc. The jaws are placed inside the place to be measured and then opened

Micrometer and it's main parts

Micrometer and It's Parts:  Micrometer   Micrometer: The micrometer may be a precision measuring system, employed by engineers. Each revolution of the rachet moves the spindle face 0.5mm towards the anvil face. The object to be measured is placed between the anvil face and the spindle face. The rachet is turned clockwise until the thing is ‘trapped’ between these two surfaces and therefore the rachet makes a ‘clicking’ noise. This means that the rachet can't be tightened anymore and therefore the measurement are often read.   Main Parts of Micrometer: 1.      Main Frame 2.      Zero adjusts screw 3.      Anvil 4.      Spindle 5.      Anvil Face and Spindle Face 6.      Lock Nut 7.      Sleeve 8.      Thimble 9.      Rachet 1.      Main Frame: It’s a c shaped frame as identified within the figure, may be a rigid part that has both holding points for employment or object to be measured. Its size depends on micrometer measuring range so

Milling Machine

Milling Machine: Milling machine is one of the best machines in Mechanical World. Milling is that the process of removing metal by feeding the work past a rotating multipoint cutter. In milling operation the speed of metal removal is rapid because the cutter rotates at a high speed and has many cutting edges. Thus the jobs are machined at a faster rate than with single point tools and the surface finish is also better due to multi-cutting edges. Milling machine is one among the foremost important machine tools in a tool room as nearly all the operations are often performed thereon with high accuracy. The indexing head makes the machine suitable for therefore many purposes as exact rotation of job is feasible by its use. Milling machine augments the work of a lathe and may produce the plain and curved surfaces and also helical grooves etc. The miller could also be so arranged that the several cutters are mounted on the arbor at an equivalent time, thus increasing the metal rem
