Principle of As-300 Hall Flowmeter

Principle of As-300 Hall Flowmeter

Hall Flow Rate of 50 g metal powders AS-300 Hall Flowmeter Funnel determines flow rate by measuring the time taken by 50 gram of a metal powder to flow through a calibrated hall flowmeter funnel/orifice of standardized dimensions(0.1 inch/2.5 mm) according to International Standards.



Apparent Density of free-flowing powders AS-300 Hall Flowmeter determines the apparent density by permitting a volume or certain quantity of powder in a loose condition to flow from a hall flowmeter funnel orifice Diameter 0.1 inch/2.5 mm into a specified density cup of definite volume(25 cm³) under controlled conditions.  The mass of powder per unit volume (the ratio between the mass and the volume) is recorded and reported as apparent density.



Apparent Density of non-free-flowing powders AS-300 Hall Flowmeter determines the apparent density by permitting a volume or certain quantity of powder in a loose condition to flow from a Carney funnel diameter 0.2 inch/5.0 mm into …

Milling process information

Milling


Introduction:-Milling is a process performed with a machine in which the cutters rotate to remove the material from the work piece present in the direction of the angle with the tool axis. With the help of the milling machines one can perform many operations and functions starting from small objects to large ones.
                        Milling machining is one of the very common manufacturing processes used in machinery shops and industries to manufacture high precision products and parts in different shapes and sizes.

types of milling machines
1) Vertical Milling Machines:- The vertical mill has a vertically arranged spindle axis and rotate by staying at the same axis. The spindle can also be extended and performing functions such as drilling and cutting. Vertical mill has got two further categories as well: turret mill and bed mill.
                        The turret mill has got a table that moves perpendicularly and parallel to the spindle axis in order to cut the material.The spindle is, however, stationary. Two cutting methods can be performed with this by moving the knee and by lowering or raising the quill.
                          The other is the bed mill in which the table moves perpendicular to the axis of the spindle and the spindle moves parallel to its axis.

2) Horizontal Milling Machines:-The horizontal mill is also the similar cutter but their cutters are placed on a horizontal arbor. A lot of horizontal mills have got rotary tables that help in milling in various angles. These tables are called the universal tables. Apart from this all the tools that are used in a vertical mill can also be used in the horizontal mill.

Adavantages of milling machine :- 1) Metal is removed at a high speed it can be controlled and rotated also..
2) it is a possible to cut metal with more than one cutter.
3) it can be movable in different angles while cutting.
4) it gives wide range of applications due to its cnc involvement.
5) it is give more accuracy..

Limitations of milling machine :-1) cost of milling machine is high.
2) as milling cutters cost high, the investment  for procuring  tools is more.
3) the production cost will increase if we carry out the operation performed in a shaper or a drilling machine with a milling machine.
