Horizontal Milling Machine Basics: Definition, Features, Construction & How Does It Work | CNCLATHING


There are two main categories of milling machines in a common machine shop: vertical mill and horizontal mill, designed in different structures and for a variety of production use. In this article, follow us to learn about the horizontal milling machine definition, features, construction, and working.

What is Horizontal Milling Machine?

The horizontal milling machine is a type of machine tool with a spindle parallel to the worktable, used to process various planes, inclined planes, and grooves with cylindrical milling cutters, disc cutters, angle cutters, forming cutters, end mills, and more tools. When you need to cut one or more grooves in a material, create slots or work on multiple sides and several planes, as well as complete large projects with extremely heavy material, the horizontal mill is the best solution for your project. Click the guide below for the difference between horizontal machine and vertical machine.

Features and Advantages of Horizontal Milling Machines

– A horizontal mill is a better option for complex projects than vertical milling.

– Horizontal milling machines usually have short and thick cutting tools.

– The spindle sleeve can be fed in a micro amount manually and equipped with a limit device. The milling head can rotate 45 degrees clockwise or anticlockwise.

– The worktable can be manually or automatically fed vertically and horizontally, and move vertically.

– The main drive and feed adopt gear speed change mechanism, which has a wide range of speed regulation.

– The spindle bearing adopts tapered roller bearing with strong bearing capacity and energy consumption braking, which has large braking torque, quick stop and reliable braking.

– The rectangular guide rail has good stability.

– The worktable and guide rail are quenched by super audio frequency, the strength is greater.

How Does a Horizontal Milling Machine Work? - Working Principle of Horizontal Milling Machine

Horizontal milling machines do not use a fixed spindle, multiple cutters can be mounted on a horizontal spindle across the table when the horizontal arbor stretches across the entire length of the bed, the rotating cutting tool press against the workpiece and remove excess materials from the piece to produce the desired CNC milling parts. Some horizontal machines have a built-in rotary table that allows milling at different angles.

What are the Main Parts of a Horizontal Milling Machine? - Construction of Horizontal Milling Machine

A horizontal milling machine is consists of the following basic components. More parts like vertical knee traverse crank, cross feed hand wheel, table traverse hand wheel, vertical positioning screw, machine vice, cutting tool, and more are situated on it. With the development of machine tool manufacturing techniques and CNC machines, the construction of horizontal milling machines will differ from previous types to suit modern applications. 

1) Base: the main part of various types of milling machine, along with column, used to support the table and align, hold the machine.

2) Table: used to hold and secure the workpiece to be machined.

3) Column: along with the base, to hold, align and support the machine.

4) Knee: can move up and down to position the piece, supports the saddle and table.

5) Saddle: attached to the knee, provides in and out, or Y-axis table travel.

6) Spindle: mounted with the cutting tool, holds the tool and provides rotation.

7) Overhanging arm: align and support the arbor support.

8) Arbor support (bracket): attached to the overhanging arm, supports the end of arbor that is opposite the spindle. 

9) Arbor
