💚 MILLING MACHINE: Types, Brands and Prices

How Does It Work, And What is a Milling Machine ?

The milling machine basically consists of a motor-driven spindle, which mounts and rotates the milling cutter, plus an alternative adjustable work table, which mounts and feeds the work piece. With them it is possible to machine milling work on flat, curved or irregular surfaces, by feeding the workpiece against a rotary cutter containing a multiple cutting edge.

Types of Milling Machines in United State and Canada

Horizontal Milling Machine

The spindle’s axis of rotation is horizontal to the table. And because of the horizontal spindle axis, it is called a horizontal milling machine.

The column of the horizontal smooth milling machine contains the drive motor and gearbox and a fixed position horizontal milling spindle. An adjustable upper arm containing one or more spindle supports projects forward from the top of the column.

Vertical Milling Machine

A milling machine in which the spindle axis is perpendicular to the table is called a vertical milling machine. Flat vertical machines are characterized by a spindle located vertically, parallel to the face of the column, and mounted on a sliding head that can be raised and lowered by hand or with power. Modern vertical milling machines are designed so that the entire head can also rotate to allow work on angular surfaces.

Knee-type Milling Machine in United State

The milling machine that has a knee-shaped projection in the center is called a knee-type milling machine. It features a vertically adjustable work table that rests on a knee-holding saddle.

Ram Type Milling Machine

A milling machine that has a ram at the top of the column is called a ram-type milling machine. Generally, the ram is used in a vertical milling machine. It can be moved in the column in a transverse direction.

Manual Milling Machine in Canada

This is the most common milling machine, which has 5 basic components, they are the work table, the saddle, the head, the knee and the arm. Considered to be the simplest type of machine, its cutting device is vertically suspended to enable metal drilling. This is generally used when creating automotive parts because it is small and practical.

Universal Milling Machine

It is the addition of a rotating table housing between the table and the machine seat. This allows the table to swing up to 45° in any direction for angle and spiral milling operations.

Milling Machine for Metal

It is a machine used to remove metal from the workpiece with the help of a rotary cutter called a milling cutter. It is used to machine flat, rough and irregular surfaces and this is done by feeding the workpiece against a rotary cutter.

Industrial Milling Machine

Industrial milling machines are one of the most versatile machines you will find in any machine shop. It is an essential machine that all manufacturers need in their shop because it helps to complete projects easily. They have a rotary table that is attached to the saddle that can be rotated (turned) horizontally in any direction.

Mini Milling Machine

The mini-milling machine can be clamped or screwed directly to the workpiece being machined or manufactured. Configuration templates and parallel mounting accessories can be used to position it in difficult conditions in the work area.

Asphalt Milling Machine

Also known as asphalt grinding, it is carried out by heavy-duty construction equipment known as milling machines or cold planers. Inside the milling machines, there is a large rotating drum that extracts and grinds the asphalt surface.

This rotating drum holds the carbide cutters that actually cut the pavement. The carbide cutters are positioned so that after they are cut, the milled pavement is automatically moved to the center of the drum.

Types of Drillers for a Milling Machine

The Slitting Mill

It’s essentially a very thin flat strawberry. It is ground slightly thinner towards the centre to provide lateral clearance. These cutters are used for cutting and milling operations in narrow and strait slots.

Side Mills

They are essentially simple burs with the addition of teeth on one or both sides. When the teeth are added to only one side, the cutter is called a half-side cutter and is identified as a right or left cutter.

Helical Cutters

The twist drill is similar to the flat drill, but the teeth have a helix angle of 45° to 60°. The steep helix produces a cutting action that produces smooth, vibration-free cuts. This type of twist cutter is particularly useful for milling elongated slots and for light cuts in soft metal.

End Mills

The end milling cutter, also called end milling machine, has teeth at the end and on the periphery. End mills can have either straight or spiral grooves. Spiral end mills are classified as left or right hand cutters depending on the direction of rotation of the flutes.

The T-Slot cutter

Used for machining T-slot slots on work tables, fixtures and other clamping devices. The cutter has a flat or side milling cutter mounted on the end of a narrow shaft.

Angle Milling Cutters

The angle cutter has peripheral teeth that are neither parallel nor perpendicular to the cutter axis. Common operations performed with angle cutters are cutting V-notches and sawing. Angle cutters can be either single-angle cutters or double-angle cutters.

Concave and Convex Cutters

Concave and convex cutters are toothed cutters formed to produce concave and convex contours of 1/2 circle or less. The cutter size is specified by the diameter of the circular shape the cutter produces.

Corner Rounding Cutter

The corner milling cutter is a toothed cutter formed to mill rounded corners in pieces up to a quarter of a circle. It can also be used to cut ratchets and slotted shafts.

Accessories for the Milling Machine

Vertical Spindle Attachment

This accessory converts the horizontal axis of a horizontal milling machine into a vertical axis. It is fixed to the column and driven from the horizontal axis. It incorporates provisions for positioning the head at any angle, from vertical to horizontal, in a plane at right angles to the machine axis.

Universal Milling Attachment

This device is similar to the vertical axis accessory, but is more versatile. The cutting head can be rotated at any angle in any plane, while the vertical axis attachment only rotates in one place from horizontal to vertical.

Rotary Table or Circular Milling Attachment

This accessory consists of a circular worktable containing T-slots for the assembly of workpieces. The circular table rotates on a base attached to the milling machine work table.

Milling Machine Table

When clamping a workpiece on the milling machine’s worktable, the table and the workpiece must be free of dirt and burrs. Workpieces that have smooth machined surfaces can be clamped directly to the table, as long as the cutter does not come into contact with the table surface during milling.

When clamping workpieces with unfinished surfaces in this manner, the table face must be protected from damage by using a wedge under the workpiece.

Parts of a Milling Machine

Column and Base

  • The column that includes the base is the main molded part that supports all other parts of the milling machine.
  • The column contains an oil reservoir and a pump that lubricates the spindle.
  • The column rests on the base and the base contains a coolant reservoir and a pump that is used during the machining operation that requires coolant.

Knee

  • It’s a casting that supports the saddle and the table. The entire gear mechanism is locked inside the knee.
  • The knee is supported and adjusted by a vertical positioning screw (lifting screw).
  • The lift screw is used to adjust the knee up and down by raising or lowering the lever with the help of the hand or feed.

Saddle and Rotary Table

It’s present on the knee and holds the table. It slides on a horizontal dovetail at the knee and the dovetail is parallel to the axis of the spindle

Power Supply Mechanism

It is the knee that contains the power supply mechanism. It is used to control the longitudinal (left and right), transversal (entry and exit) and vertical (up and down) feeds.

Table

  • It is a rectangular mold that is present in the upper part of the saddle.
  • It is used to hold work or work holding devices.
  • It contains several T-slots to hold work and work holding devices (i.e. templates and accessories).

Shaft

  • This is the axis used to hold and drive the cutting tools of the milling machine.
  • The shaft is mounted on the bearings and supported by the column.

On the arm / Protruding Arm

It is a horizontal beam present on the upper face of the column. It can be a single molded part that slides over the dovetail shapes present on the top face of the column.

Tree Support

  • It is a mould with a bearing that supports the outer end of the shaft. It also helps to align the outside end of the shaft with the shaft.
  • The shaft support has an oil reservoir that lubricates the bearing surfaces. It can be attached anywhere on the axle.
  • The protruding arm on the vertical machine is called a ram. One end of the ram is mounted at the top of the column and the other end is fixed to the milling head.
  • The ram can be moved transversely (in and out) on the column with a hand lever.

How to Make a Home Wood Milling Machine

  • It is common the use of materials and pieces in disuse of old cars and other devices for the manufacture of home tools, which help us to perform our carpentry work at home, in this specific case we will review the construction of a home milling machine
  • It consists of a wooden base on which the frame is mounted; a mechanism comprising the main shaft; a ring and pinion gear taken from an old car, and an emery wheel about 19 cm in diameter.
  • The frame is made of a steel plate, cut according to the pattern, drilled in the places indicated, and bent at right angles along the dotted lines, the legs are screwed to the base, threads for nuts are transferred to the main shaft, and it is assembled on bearings and strong bronze washers.

History of the Milling Machine

  • A milling machine is a wheel cutting machine, dating from the 1700s and used by watchmakers, were the forerunners of industrial milling machines.
  • Although it is not clear who invented the first real milling machine – a lathe-like device featuring a rotating cutting tool instead of a rotating workpiece – evidence supports its existence in 1818 in the United States.
  • Whitney produced the machine, along with several others, with the goal of mass producing pistol parts. In 1798 he contracted with the federal government to produce a large order of muskets. Whitney remedied this by building a semi-automated machine tool factory.
  • In 1867, the American engineer Joseph R. Brown (1805-1870) presented his universal milling machine at the Paris Exhibition. Brown’s machine emerged after tests in 1861 of one designed to solve the problem of producing spiral lathes.
  • This machine proved to be incredibly versatile, and led to Brown’s important addition in 1864 of a shaped cutter. Since then, milling machines have competed with lathes as the most widely used industrial machine tool.
