Milling | Overview, Characteristics, Types [Explained with Image]
miling machines are maybe the most generally utilized in assembling after machines.
Notwithstanding, processing machines use multi point cutting instrument however machine machines utilize single point cutting device.
What is milling?
A processing machine utilizes a shaper with a numerous teeth, these teeth (one by one) connect with the work piece for a little measure of time. This outcomes in a little chip size and variety in chip thickness. The surface complete acquired by the processing procedure is by and large of good quality.
To perceive how processing really occurs, it would be ideal if you see connected video toward the finish of this article.

Types of milling
Up Milling (traditional processing)
This is a sort of processing in which course of pivot of haggle of workpiece is inverse. You can allude beneath picture to comprehend the idea and the contrast between up processing and down processing.
Down Milling (climb processing)
In this sort of processing the course of pivot of haggle of workpiece is same.
With this outline appearing and down processing you can comprehend the procedure betterly.
Up and Down Milling
Points of interest of down processing
Reasonable for thin and difficult to hold machine parts
Work require not to be braced firmly
Consistency kept up extraordinarily for thin parts
Requires 20% less power than up processing
Utilized in processing profound and thin openings
Weaknesses of down processing
It can’t be utilized except if the machine has kickback eliminator
It can’t be utilized for processing hard materials, since it can harm shaper
