A milling machine is basically used for shaping, routing, boring, and drilling metals and other solid materials. Generally there are two categories of the milling machine which include the vertical type and the horizontal type. In order to optimize the capacity of the milling machine, it is essential to identify the appropriate milling machine type for specific tasks.
Principle of Operation of the Shaping Machine 1. Shaper machine is used for generating flat surfaces. 2. Single Point Tool reciprocates on the job. 3. Job is fed across the tool. 4. Tool is moved downward after completion of cross feed. 5. The length of stroke and position of stroke can be changed.

Mar 04, 2016· There are two ways to cut the material from the work piece through milling machine. First one is named as conventional milling or Up milling and the other one known as climb milling or down milling. The main and basic difference between up milling and down milling is the direction of rotation of cutter to the feed.

Gelatinization occurs by mechanical means such as grinding, pressure, and by hot water. Soft feed at an environmental temperature of 25°C can be brought to a temperature of 85°C by the addition of 4 to 6 percent moisture from steam. Frictional heat due to passage of feed through the pellet mill adds 2 or 3 degrees of temperature.
