Types of Jigs and Fixtures:
There are several types of Jigs and Fixtures available in the market. Also, you can create a Jig and Fixture by yourself to do an operation easily. it is up to you. Although these are some available Jigs and Fixtures in the market.
Types of Jigs:
Here are some simple drill jigs:
Angle plate jig
You can check this slide to get an idea about this.
Types of Fixtures:
These are some Fixtures available in the market:
Angle plate fixture
Difference between Jigs and Fixtures:
Here is the difference between Jigs and Fixtures:
It holds and locates the work as well as guides the tool.
It holds and locates the work but does not guide the tool.
These are lighter in construction and clamping with the table is often unnecessary.
These are heavier in construction and bolted rigidly on the machine table.
Used for holding the work and guiding the tool in drilling, reaming or tapping operation.
Used for holding the work in milling, grinding, turning or planning operation.
Gauge blocks are not necessary.
Gauge blocks may be provided for effective handling
The cost is more.
The cost is less as compared with the jigs.
Their designing is complex.
Their designing is simple as compared to jigs.
Why should we use Jigs and Fixtures?
Let's see some advantages of Jigs and fixtures:
It eliminates the setting time required before machining.
It increases the machining accuracy and also increases production capacity.
Requires less skilled operation.
They reduce the production cost.
Increases machine and labor utilization.
They simplify the work handling.
Increases the quality of production in the industry.
They enable the quick setting of a tool and the proper positioning of the work.
Although there are so many advantages by using Jigs and Fixtures, but also there are some disadvantages too.
Disadvantages of Jigs and Fixtures:
Can wear away over time.
Another one is the high initial set up costs (and time).
And can use a lot of material and be bulky.
Applications of Jigs and Fixtures:
There are various fields where we can use Jigs and Fixtures and those are:
Mass production of automobile parts.
Inspection of parts in continuous production in manufacturing industries.
Cutting the ingots in the steel plant.
In the refrigeration industry.
Pump assembling process
For drilling the flanges and drilling holes to any required angles.
For multi-spindle machining.
Jigs used for mass drilling, reaming and tapping.
For guiding the tools for machining contours.
Fixtures used for milling, mass turning, and grinding operations.
The Material used for Jigs and Fixtures:
These are the following material is used for making Jigs and Fixtures:
Grey cast iron
Low melt alloy steels
Jigs and Fixture is an essential element in Manufacturing Technology. There are several factors you should consider to make jig and fixtures. By using these you can save a couple of production time.
Here in this article, I covered all the important points regarding Jigs and Fixtures. I hope you understand everything.
