Jig boring machine is similar to milling machine. But the work produced by jig boring is quite precise. If spindle is rigid and machine itself is massive, therefore the defects, deflection, vibration etc. developed due to change in temperature is insignificant. More precise and high quality holes are required in drill jigs, fixtures and dies.

CNC milling is a specific form of computer numerical controlled (CNC) machining. Milling itself is a machining process similar to both drilling and cutting, and able to achieve many of the operations performed by cutting and drilling machines. Like drilling, milling uses a rotating cylindrical cutting tool.

MACHINE INTRODUCTION Milling is a machining process of removal of metal by feeding the work piece against rotating multipoint cutter. As the cutter rotate, each cutting edge removes small amount of material from the work piece. This process is used to generate flat surfaces or curved profile and many other complex shapes with great accuracy and having very good surface finish.

of Milling In milling machine, the metal is cut by means of a rotating cutter having multiple cutting edges. The work piece is fed against the rotary cutter. Metal is removed in form chips of trochoid shape. Machined surface is formed in one or more passes of the work. The work to be machined is held in a vice, a rotary table, a three jaw chuck, an index head, between centers, in a ...

A pharmaceutical ball mill is a type of grinder used to grind and blend materials while manufacturing various dosage forms. The size reduction is done by impact as the balls drop from near the top of the shell. Ball mills are used primarily for singlestage fine grinding, regrinding, and as the second stage in twostage grinding circuits.
