Types of Vices and their Applications
What is vice?
Types of vices And Their Applications :- A vice is a mechanical apparatus that is used in securing an object to allow work to be performed on it i.e., to hold a work piece rigid at a stationary position. Vices consist of two corresponding jaws, one is static and the other can be moved in and out by a screw and a lever. It is used in multiple areas and fields such as a mechanical workshop, metalworking, woodworking etc.
The vice is attached to the bench, and therefore named as a bench vice or workbench vice. The bench vice are attached to a bench to give the operators comfort or ease while using the vice and to be easily accessible also.
If the working surface is stable a bench vice doesn’t need to be attached to the workbench. It can be attached directly to the surface or the side. A vice is entirely made up of metal because of this reason, the linings in the jaws are made with wood or some similar kind of materials. This assists the integrity of the work piece. Jaws are replaceable if worn out over time.
The complete construction of the bench vise is made up of cast iron. Both of the jaws of this vice are made of tool steel and the spindle handle of the vice is made up of mild steel. This vice has wide range of applications in a workshop.
bench vise parts and function
The parts of the bench vise are as follows:-
❏ Fixed Jaw
❏ Movable Jaw
❏ Jaw Plate
Construction of bench vise
The fixed jaw of the bench vice is cast along with the vice and the movable jaw is fixed with it. In both types of jaws, the tool steel plate is attached with a plate screw, which has dents in it. These dents are the reason for the grip of the job being very strong. If the jaw plate gets damaged it can also be replaced.
The spindle of the bench vice is fitted opposite to the movable jaw, which is fixed with the help of a spring and a pin. This spindle sets in the box-nut tightened in the fixed jaw. The holder of the round rod of the bench vice is settled in a hole made in the origin part of the vice. By revolving this handle of the vice the movable jaw moves ahead or backwards. The job is held between these two jaws (the fixed one and the movable one). The vice size is measured by its breadth. The Vice is tightened with two or three bolts on the round table.
Types of Vices and their Applications
1. Pipe Vice: ( Types of Vices )
The pipe vice is used in the plumbing work to hold the pipes in the vice to secure the tubing when cutting or threading is done. It is designed to hold the vice pipes which are as small as 3mm or as large as 200 mm. It may be fitted on a workbench or may be used with a mobile tripod stand. The mobile tripod stand is usually used for projects to be performed outside the workshop, they are portable, and are easy to transport. We can combine two or more for longer pipes.
2. Machine Vice: ( Types of Vices )
It is important to hold a job strongly for performing operations like milling, drilling, slotting or shaping. For doing the work for such operations machine vice is used. This machine vice is fixed on the table. The T bolts are used, which fasten the vice tightly and easily in the “T’” slot.
Types of machine vice
A) Plane machine vice
The plane machine Vice is used to fasten light jobs. It is also called the light-duty machine vice. Its fixed jaw is the one longer in the size. And the movable jaw moves ahead or backwards on revolving the spindle.
B) Flange machine vice
The flange machine vice is also known as the heavy-duty machine vice. For fastening the type of jobs that get frequent shocks at the moment of machining this type of machine vice is used. On one of the ends of the spindle, a square end is made which contains a box type handle fixed to it, to revolve it.
C) Universal machine vice
This is a machine vice that is highly useful and widely used. The quality of this machine vice is that with it job can be held in various positions such as
It is majorly used in tool-making.
D) Vertical machine vice
The next type of machine vice is vertical machine vice. This vice is different from all other kinds of vice. As the name suggests in this vice jobs are held in a vertical position. This vice consists of flanges instead of jaws. It is very easily operable.
E) Swivel machine vice
In construction and shape, the swivel machine vice is similar to a flange machine vice but it has a different kind of base, the vice can be revolved at any angle, with the help of this machine base. It has the quality which is that without separating the job from the vice straight or angular machining can be done.
