3 Types of Marking out Tools used in Fitting:

The Detailed Explanation of Marking out Tools used in Fitting are shown below.

1.Scriber:

  • A scriber is a steel tool, used to scribe or mark lines on metal workpieces.
  • It can be used in conjunction with a try square.

2.Dot Punch:

  • It is used to specify the path of cutting.
  • Firstly, the path is to be marked with a scriber and then with the help of dot punch,the path is hitted by a hammer.
  • For this purpose, the punch is ground to a conical point having 60 degrees included angle.

3.Center Punch:

  • This is similar to the dot punch, except that it is ground to a conical point having 118 degrees included angle.
  • It is used to mark the location of the holes to be drilled.

  • The Parts of Bench Vice are

a. Jaws

      – Fixed Jaw

      – Movable Jaw

b.Body

c.Handle

Parts of Bench Vice-Explanation:

1.Jaws:

The Jaws are used to hold the workpiece by rotating the handle. In that, one jaw is fixed and the other is movable.

2.Body:

All the parts like a handle, jaws etc.are connected to the body of a bench vice.

3.Handle:

  If the handle is rotated in CW direction, then the workpiece is fixed between two jaws.

  If the handle is rotated in CCW direction, then the workpiece is loosened from the jaws.

3.Pipe Vice:

  • It is similar to Bench Vice but here the Circular/Cylindrical components are to be placed in between the upper and lower jaws due to the curvature of existing jaws.

  • The Parts of pipe vice are handle, screw spindle, movable and fixed jaws, etc.

4.Hand vice:

  • A hand vice is a tool which is designed to hold the workpieces in between the jaws.

  • The wingnut is tightened in CW direction to hold the w/p and loosened in CCW direction.

5.Tool maker’s vice:

  • The screw-driven movable jaw for applying clamping force.

  • Made from hardened alloy steel.
  • Single piece construction with V-grooved Jaws.
  • All surface including Jaws and Base are precision ground square and
    parallel.

1. Cross-peen hammer:

  • It has a cast Steel body and a wooden handle.

  • The body has two parts. They are: face and Peen.

  • In cross peen hammer, the peen is in the form of narrow round edge used to remove the unwanted material from the workpiece.

2.Claw hammer:

  • It is used for striking as well as for pulling the nails from the wood.

  • The claw face is used for pulling out the nails and the head face is used to drive the nails.

  • It is made up of cast Steel.

3.Mallet:

  • It is used to strike the chisel on a wooden component.

  • It is made up of hardwood and is round or rectangle in shape.

    These are the different Striking Tools used in Engineering Workshop.
