Feature of vertical milling cutter

Milling machine: A mulling machine is a power driven machine that cut by means of multitooth rotating cutter.
The mull is constracted in such a manner that,  The fixed workpiece or tooth frrd to Againest ride to the cutter or job.
Verities of cutter and holding devices allow a wide range of cutting possibilities.

Main parts of a vertical milling machine

1.Base: Base and colony mn are originally one fixed parts. This parts is integrally made by casting operation.
The front of column is a machined face which provides the way to vertical  movement of nee.

2.knee: knee is holder of working table & all of the operating gear keys.

3.Saddle: The saddle slides in dovetaild groves into the away from the machine.
providing the mill with it's y-axis movements.
On the top of the saddle sits the table.



4.Head: In a vertical milling machine, Head is main parts of milling machine.
in a milling head contains,
♦ The motor drive switch and on/off switch.
♦Drive belt, gear train, and range lever selector.
♦Quill, spindle, draw ber.
♦in z axis feed, lock, digital depth read out.

5.working table: In working table, job is be attached. Fixed by fixure or Machine vice.

6.Fixure & table vices: Fixure and table vices are to catch workpieces for operation.  Fixure in attached to a platform inside the milling machine.



7.cutting tool: The cutter is a metal cutting tool with sharp teeth. This is also secured in that milling machine and rotates at high speed.



8.Arbour: An arbour is consider as an extension of the machine spindle on which cutters are securely mounted and roted.
The arbours are made with tapper shanks for proper alignments with machine spindle having tapper hole on their tapper nose. The tapper shanks of the arbor confirms the Morse tapper or self release tapper.

9.spindle: the spindle of the milling machine is locate in the upper parts of the column and receive power from motor by belt or gears and clutches and transmit to the arbor to the front end of the spindle from the column face and it is provided with a tapped hole into too which verious cutting tool and arbor may be insided.

♦ Construction of vertical milling Machine :
Milling machine may be defiened as the type of machine in which the metal is removed by rotational cutter,  where the job is to be feed against revolving cutter or cutting tool.  Which has one or more cutting blades or edge.

        And also have several parts.
i just try to do designate main parts of Vertical milling cutter.
