BROACHING

BROACHING:-

Broaching is a machining process that uses a toothed tool, called a broach, to remove material. 

There are two main types of broaching: linear and rotary.
In linear broaching, which is the more common process, the broach is run linearly against a surface of the workpiece to effect the cut.

Linear broaches are used in a broaching machine, which is also sometimes shortened to broach.

In rotary broaching, the broach is rotated and pressed into the workpiece to cut an axis symmetric shape. A rotary broach is used in a lathe or screw machine. In both processes the cut is performed in one pass of the broach, which makes it very efficient

What is difference between Welding and Brazing?



Ans. In Welding concentrated heat (high temperature) is applied at the joint of metal and fuse together.

In Brazing involves significantly lower temperatures and does not entail the melting of base metals. Instead, a filler metal is melted and forced to flow into the joint through capillary action.
