Types Of Milling Machines

Introduction

In this article, we will learn about Types of Milling Machines. Milling is the name of the milling machine used for moving the material against the rotating multipoint cutting tool and the machine used for the milling operation. The milling cutter,

which has a multi-point cutting tool and rotates at high speed, can cut out much metal quickly. More than one milling cutter can work simultaneously. The milling cutter rotates in a stationary position and the work material is placed on the table and moved.

Types of Milling Machines

Depending on the layout of the machine, the following can be divided into several categories.

i. Plain milling machine
ii. Universal milling machine
iii. Vertical milling machine Bed type milling

i. Simplex milling machine
ii. Duplex milling machine
iii. Triplex milling machine

i. Rotary table milling machine
ii. Profile milling machine
iii. Planetary milling machine
iv. drum type milling machine

1. Column and Knee Type Milling Machine

These types of machines rotate where the arbor was. Arbor cannot be loaded down and down. Table loading or unloading machining is only done at the top. the machine.

i) Plain (or) Horizontal Milling Machine

It is a machine that can be used for common tasks. In which the vertical column face in the base Knee up and down in the guideways in the area. The saddle on Saddle and Saddle on Table. It can also be called Horizontal milling machine because the spindle in the machine is horizontal.

Base

The base made by Castiron bears the column section. The bottom is set up like a tank and stored in lubricating oil.

Column

Name the column for the nest-like area that is perpendicular to the base. Inside it will be the driving mechanism to drive the spindle, and the front and knee up and down Dovetail guideways. Spindle and overarm are located in the upper part of the column.

The guideways on the top of the Knee Saddle move the column in or out of the column.

Saddle

The saddle is in the upper part of the Knee. Moving back and forth across the Dovetail guideways. The table is mounted on top of it

Table

It is set on Saddles. The top of the table is precisely machined and the T slots are mounted to hold the machine vice or workpiece.

Spindle

The spindle is located at the top of the column. The rotating key of the motor is precisely obtained by driving gears. There is a driving mechanism that allows you to rotate at different speeds. At the tip of the spindle is a self-releasing taper. This is where the arbor comes in.

Overarm

This is the bearing frameset at the top of the column section. This can be moved back and forth as needed. The arbor bearing is supported by support called a yoke. Attachment When working on the attachment the overarm can be pushed back completely.

Arbor

The name of the arbor for the cutter bearing bar. A specially placed tip is inserted into the spindle and pulled. Using the sleeve s the cutter will be fitted where needed. In Arbor there is a key way to tighten the cutter with the key. At the other end of the arbor, the arbor is mounted on the yoke.

ii). Universal Milling Machine

The name of a universal milling machine is a machine that has the equipment and equipment to perform various types of milling operations. Like the planing milling machine, you can move the table in longitudinal and cross-wise, and move the table to the right and to the left by machining the table to 45 °.

By turning the table the object moves at a specified angle against the spindle axis. It is used for helical milling.

An indexing head, universal dividing head CUTTONTM attachments can accurately cut gears, helical groove, helical gear, bevel gear, drill bit, reamer. Most used in Tool Rooms.

Omniversal milling machine

It is specially designed to move the table in many directions. Usually, the table is moved and the table can be set at any angle to the vertical axis. You can also move the knee in a long way. The reamer and bevel gear can be easily cut.

iii) Vertical Milling Machine

Vertical milling spindle table axis is located perpendicular to the axis. This machine is in the vertical column on the base.

The front of the column will knee and move up and down the guideways. The crosswise saddle moves over the spindle axis in the horizontal guideways in the upper part of the Knee. The table moves in length along the guidelines at the top of the Saddle. The spindle head is at the head of the column. The spindle head has a swivel base.

This allows the head to be turned to the desired angle. This makes it easy to machining work surfaces at any angle. On some machines, you can move the spindle up and down, move the Knee vertically, saddle the crosswise, and move the table by hand or by power.

It is used for machining grooves, slots, etc. End milling and face milling cutters are commonly used.

2. Plano Miller

Plano miller’s layout is similar to a double housing planer. It works the same way the planner machine works. In the guideways in the upper part of the bed, the table moves in length.

Cross the rail in two vertical column guides on either side of the bed and move down. Two tool heads fitted in the guideways on the cross rail and move horizontally. There are two tool heads in each column to navigate through the guideways in the Column. These vertical and horizontal tool heads are operated by a separate motor.
