Parts of Shaper Machine:


 Shaper Machine


Following are the common parts of shaper machine:

1.     Base
2.     Column
3.     Cross-rail
4.     Table
5.     Ram

1. Base:

The base is the necessary bed or support required for all machines tools. It is hollow casting made of cast iron to resist vibration and on which all parts of the shaper are mounted. It is so designed that is can take up the entire load of the machine and the forces set up by cutting tool over the work.



2. Column:

The column is made of cast iron, which is a box-like and is mounted on the base. Two accurately machined guideways are provided on the top of the column on which the ram reciprocates. The column acts as a cover to the drive mechanism and also supports the reciprocating ram and the worktable.



3. Cross-rail:

Cross rail is mounted on the front vertical surface of the column on which saddle is mounted. The vertical movement is given to the table by raising or lowering the cross rail using the elevating screw and the horizontal movement is given to the table by moving the saddle using the crossfeed screw.

 

 

4. Table:

The table is bolted to the saddle and receives crosswise and vertical movements from saddle cross rail. Here T-bolts are used for clamping on top and sides. It can be swiveled at any required angle. In a universal shaper, the table may be swiveled on a horizontal axis and the upper part of the table may be fitted up or down. In heavier type shaper the table clamped with table support to make it more rigid.



5. Ram:

The ram reciprocates on the column guideways and carries the tool head with a single-point cutting tool. The tool head is in the clapper box, which causes cutting action only in a forward stroke of the ram and sliding movement of the tool in the reverse stroke of the ram. The depth of cut or feed of the tool is given by down feed screw. The tool head has swivel base degree graduations, which helps to move the tool head to any desired inclination for machining inclined surfaces on the workpieces.

Definition and Parts of a Vernier Caliper

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
