Milling machines are very versatile. They are usually used to machine flat surfaces, but can also produce irregular surfaces. They can also be used to drill, bore, cut gears, and produce slots. The type of milling machine most commonly found in student shops is a vertical spindle machine with a swiveling head.

Guideline To Operate A Milling Machine. First of all, look carefully into the machine, you will see a handle. That's the handle that you've to move. You may also notice a rapid switch on the X-axis. On that axis, you can move the table while operating. Always remember, you can only move the table backward and forward on the X-axis.

Ball end mills produce a radius at the bottom of pockets and slots. Ball end mills are used for contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket.

machine can understand and convert into actual motion of the machine. The Control Computer reads the G - Code file line by line and commands the machine to do the movements. The language consists of a set of codes called G - Codes and M - Codes, each instruction have a specific function, for example to command a motion from one point to another.

machine, In practice this is not usually attainable. After instal- lation, the teeth of a girth gear of 7.5 diameter, for example, can be expected to have a radial run-out of 1-2 mm and more; Fig. 7. The resulting fluctuations in angular velocity mean additional load- ing on the teeth. B: No equivalent influence.

Jet mills operate in compressed air, gas or high pressure superheated steam. Jet mills have no moving parts, thereby eliminating contamination due to contact with external grinding media. It is also an ideal process to grind heat-sensitive and waxy material because no attritional heat is generated. Jet mill works on fluid energy.
