TYPES OF MILLING CUTTER

One of the important component in Milling Machine are the Milling Cutter. There a few types of Milling Cutter. To get the desire shape, the machinist must choose the correct cutting tool. The common cutting tool in market as below:-


a) Face Mill Cutter

For roughing and finishing cutting in one pass. The material removed layer by layer. The function of insert at Face Mill cutter to remove the material. Usually, in one face mill cutter we have 4pcs to 8pcs insert. If the insert wear or damage just replace it.

b) End Mill Cutter

Can perform various types of shape, for example pocket, island, side mill, also finishing or roughing.

c) Centre Drill Cutter

Before we perform the drilling, we need to use the Centre Drill first as a guidance. The depth of cut for Centre Drill usually 2 to 3mm only.

d) Drilling Cutter

The drilling process to make a hole.

e) T-Slot Cutter

Make it the slot shape.

f) Ball Nose Cutter

This cutter almost same with End Mill Cutter but end of cutter have a radius. The process can be done by this cutter for example chamfer and fillet.

g) Counter Bore Cutter

To make a counter bore screw shape.

h) Counter Sunk Cutter

To make a counter sunk screw shape.

MILLING MACHINE

Milling Machine

Milling is a process in which a machine tool removes material from a work piece by rotating a cutter and moving it into the material along various axes with respect to the work piece. It is practically a very versatile process in conventional machining because of its capability to do various types of work using appropriate cutting tools. 


Types of Milling Machine:-

Milling machines has a rotating spindle for the cutter to be placed in and a table for fastening, positional and feeding the workpiece. Basically, the types of machines found are classified into horizontal or vertical.

Horizontal milling machines has a horizontal spindle, and these type of machines are well-suited for peripheral milling process. While, the vertical milling machines are more suited for face and end milling because of its vertical spindle.

There are also more complicated types of machines which are the knee-and-column, bed type, planer type, tracer mills and the CNC milling machines.
