Milling Cutters Types, Definition, Uses & Applications

Milling cutters

Definition

The milling cutters are revolving tools having one or several cutting edges of identical form equally spaced on the circumference of the cutter. The cutting elements are called teeth.

Types of Milling Cutter:

Solid cutter

A solid cutter has teeth integral with the cutter body

Tipped solid cutter

A tipped solid cutter is similar to solid cutter, except that the cutter teeth are made of cemented carbide.

Inserted teeth cutter

In large milling cutter the teeth or blades are inserted or secured in a body of less expensive materials.

Profile relieved cutter

In this type of milling cutter a relief to the cutting edge is provide by grinding a narrow land at the back of the cutting edges.

Form relieved cutter

In this type of cutter a curved relief is provided at the back of the cutting edges.

Arbor type cutter

The arbor type cutters are provided with a central hole having a keyway for a mounting them directly on the milling machine arbor.

Shank type cutter

The shank type cutters are provided with straight or tapered shank integral with the cutter body.

Facing type cutter

The facing type cutters are either bolted or attached to the spindle nose

Right hand cutter

A milling cutter is designated as a right hand cutter which rotates in a counter clock wise direction when viewed from the end spindle

Left hand cutter

A left hand cutter is designated as a left hand cutter which rotates in a clock wise direction when the end of the spindle.

Parallel of straight teeth cutter

The parallel or straight teeth cutters have their teeth straight or parallel to the axis of the rotation of the cutter.

Right hand helical teeth cutter

These cutters have their teeth cut at an angle to the axis of rotation of the cutter. The cutter may be distinguished by viewing it from one of its end faces, when the helical groove or flute will be found to lead from left to right hand direction of the cutter body

Left hand helical teeth cutter

These cutters have their teeth cut at an angle to the axis of rotation of the cutter. The cutter may be distinguished by viewing it from one of its end faces, when the helical groove or flute will be found to lead from right to left hand direction of the cutter body.

Alternate helical teeth cutter

In some cutter the alternate teeth are provided with right and left hand helical angles.

Special milling cutter

Special milling cutters are designated to perform special operations which may be the combination of several standard operations.

Standard milling cutter

These cutters are conventional type of milling cutters whose dimension such as cutter diameter and width, diameter of center hole, width and depth of keys are standardized.
