We all have heard about a machine process called milling. We suppose that you have already heard that different details are produced with milling and they have a wide application.
But if you want to learn more about the milling process, then sit down comfortably to read because we have interesting things to explain to you.
What is detail milling?
Milling is processing different matеrials and it involves the removal of some amount of material from detail with the purpose of changing the shape of the detail. This method for processing details is widely used in different industry manufacturing processes, especially in industry spheres such as machine production, car industry, building construction, spaceship construction, etc.
The details processed with milling are called milling details. And the machines used for the milling process are called milling machines.
A few words about milling machines
Let’s start this way…Milling machines are used in the processing of hard materials with a reduction of scrap material. Depending on their technical characteristics milling machines can perform different complex operations such as cutting, threading, punching,matchboard production, and others.
The methods in which a given detail can be processed with a milling machine depend on the desired final result and also mainly on the type of the milling machine and its technical characteristics.
The machines that are currently used for processing milling details have different technical specifics. There are machines that are designed for making channels, grooves, etc., there are machines that allow us to perform different operations on large surfaces, and there are machines for creating profiles that are applied in the production of cogwheels, worms, PVC windows, etc. There are also such milling machines that are used for cutting fragments or elements from the detail that is being processed.
Applied technologies in the production of milling details
There are different types of milling machines that are used today and each type is used for different operations. There are machines that can perform one operation and machines that can perform several operations in processing milling details. Milling machines have different characteristics but depending on the applied technologies they use in detail processing they divide into two types- conventional milling machines and CNC machines.
Conventional technology (manual)
This technology has been used for many years and it’s called conventional. We call conventional those milling machines that require constant attention and the presence of an operator who is going to watch the detail processing operation.
The process of detail processing following this technology requires some preparational activities, the first of which are setting the billet and fixing it to the mandrel in a stable way, moving the detailto the processing tools, setting the parameters of the operation, changing the processing tools, etc.
Different processing tools can be used in detail processing and this allows us to perform several detail processing operations. This reduces the time needed to process the milling details. However, the manual method of processing milling details characterizes by a much slower speed and low efficiency, and it can also lead to some mistakes in the processing of details.
CNC control
CNC control enables us to operate milling machines with computer programs. With this type of control, the mechanical operator turns into an operator who can control detail processing with special digital software.
CNC control not only makes the operator’s work easy, speeds up the processing, and increases the efficiency, but it also increases the precision of the processing and reduces the amount of scrap. In other words, the CNC control systems of milling machines allow them to process a large number of details with complex geometric shapes whose processing requires excellent precision and high speed.
Application of milling details
It’s completely logical for milling machines to have a wide application in machine production. Why? The answer is pretty simple! All machines regardless of what industry they are used in consist of numerous metal details. And every detail (part) of a machine is made with a milling machine. Depending on the machine milling details can have simple or complex structures so that they will meet the specifications of the milling machine model we want to create. The most commonly used milling details in machine production are cogwheels, hemispherical and spherical details, cones, distributors, and many others.
Milling details have a wide application in construction where they are used for the production of different types of construction pipes, perforated stripes, flat sheets, thick rods (rectangular, hexagonal, cylindrical, and others), the production of special profiles, etc.
These details are widely used in our daily lives as well. Do you know that a large part of the garden decorations on the market (fences, summer-houses, railing, etc.) is made from milling details? The same is true for many of the decorations we place in our homes to spice up our interior.
The furniture that makes our homes comfortable also consists of milling details. And when it comes to the production of PVC windows (which is a thing that every home needs) milling machines and milling details are once again used.
Thanks to milling machines we can process titanium details which are very important for the progress of astronautics and more specifically for the construction of spaceships and space shuttles.
The truth is milling details can be found in almost every industry sphere. Milling details are everywhere- in grocery store products, in household appliances such as the washing machine, the refrigerator, the dishwasher, or some other white goods. They can also be elements of the machines that manufacture household products and items. There are milling details in our cars, in the structure of homes, in our PVC windows, and in our furniture, and they are also used in the processing of wooden lanes, concrete, and stone blocks.
Advantages and disadvantages of milling details
In fact, it will be difficult for you to find what are the disadvantages of these details. The production of milling details follows a modern method that is precise. The details are manufactured exactly according to the given set of parameters and getting an imperfectly processed detail is something that rarely happens. And if this happens by accident it’s usually a result of an incorrect material setting by the operator or a wrong choice of processing tools. But these mistakes are possible only when we are manually processing a detail with a mechanical milling machine.
The details that are manufactured with milling machines that operate with CPU control systems are manufactured with extremely high precision, high speed, and very high quality.
The mistakes we have mentioned above aren’t possible when using CNC systems because numerical control is used for the entire operation of processing a certain detail- from the placement of the billet to the feeding of the processing tools and achieving the final result.
What is the price of milling details production?
Usually, after learning about all these positive sides of milling details everyone is likely to think: „It’s amazing that milling details have such a wide application, but what is the exact price of a product made with milling details?”
If you also ask yourself this question, we will tell you the following:
The price of processing milling details depends on many things, the main ones of which are the number of details we want to process, what material they are made of, and the complexity of their processing method.
You can realize that no manufacturer of milling details can tell you the exact price for a product if you don’t tell them in advance what are the main parameters of the detail that you want to process.
All we can say is that the prices for manufacturing milling details are completely acceptable and reasonable (unless you want some complex milling operation for a material that is difficult for processing).
Let’s end up with a couple of historical facts
If you think that milling machines are a modern creation, then you are wrong. Despite the fact that you will hardly find an industry sphere where milling machines aren’t used, the creation of milling machines didn’t happen in our century or in the last century.
The first evidence of the use of a milling machine dates back to the 1700s. Back then watchmakers started using a machine, or to be more exact-a device, that looked like a lathe machine. This device had a cutting tool that rotated. It’s not completely clear who was the creator of this first milling machine, so all around the world, Eli Whitney was recognized as the first inventor of the predecessor of the milling machine.
In 1798 Eli Whitney signed a contract with the American government about gun (musket) production for the American army. Until this moment these guns were manufactured only manually and their parts weren’t replaceable. This made the process of gun production slow and difficult.
To change the situation Whitney settled down to work and constructed a prototype of the first milling machine. In this way, he managed to reduce the production times for the muskets and created a semi-automated firearm production.
Whitney’s invention was a good one but the universal lathe machine of the American engineer Joseph Brown that was presented at the Paris exhibition in 1867 in fact marked the start of the production of milling machines. Since then both milling and lathe machines have held their position as the most used machines in the production industry.
