A milling machine is an equipment used during metal cutting to produce parts of various shapes and sizes. Milling machine follows certain steps, in which the different parts work in conjunction with one another, and the end product is a machined part. Are you intrigued to know what all steps are involved in the working of a milling machine? Read the following post to find out.
What is the Working Principle of Milling Machine?
Before you proceed with the working of the milling machine, it is important to understand the working principle behind it.
The workpiece is held firmly on the machine’s worktable. The feed of the workpiece against the rotating cutter is controlled by adjusting the working table. This rotating cutter revolves at a great speed and is generally attached to the arbor or spindle. The only motion that the cutter has is the rotary motion. The workpiece is advanced slowly, and the metal from its surface is removed by the teeth of the cutter. This helps achieve the desired shape.
How Does a Milling Machine Work?
Now that you understand the principle on which the milling machine works, it is easier to understand its working. Here are some important steps involved in the working of milling machines:
• Step 1: The Basic Set Up
Before starting any milling process, the most crucial thing that matters the most is a proper setup. Thus, as a first step, the cutting tool adjusted at the arbor. The arbor is further attached to the spindle.
• Step 2: Knee Adjustment
In the second step, the adjustment is done to the knee position by moving it downward.
• Step 3: Clamping the Workpiece
This is where the workpiece comes into the picture. The basic set up is ready, and it is time to clamp the workpiece on the table. This is done with the help of clamping screws.
• Step 4: Zero Adjustment
Prior to beginning with the milling process, it is important to ensure that all the controlling points, such as saddle position, knee position, and others are set to zero. This helps in machining parts to exact precision.
• Step 5: The Cutting Tool
This is where the actual working begins. The spindle starts rotating, and thus the cutting tool attached to the spindle also starts to rotate.
• Step 6: Moving the Workpiece
The cutting tool is rotating continuously at a high speed. The different parts of the machine, such as table, knee, and saddle are moved slowly as required to move the workpiece.
• Step 7: Shaping the Workpiece
This is the last step of the working of the milling machine. The workpiece is now moved by the controlling axis, and the desired shape is cut into it. In this step, the tool is in the rotary motion and remains stationary.
A milling machine goes a long way into increasing the overall productivity, along with saving a considerable amount of time. Especially for the manufacturing industry, the milling machines are a great boon. However, availing milling services from experienced service providers is always advisable to get good quality precision machined parts. One such experienced and reliable provider of milling services in the USA is BDE Manufacturing Technologies. It has a team of skilled professionals, who have a great knowledge of machining.
