He industrial sector it is currently advancing at breakneck speeds. This is why they arise new and increasingly innovative solutions and different production processes with greater use of resources. But there is a industrial machining method who has been in the sector for many years and came to stay. Today we tell you what is milling and why is it so important in the industrial sector in which we move in Talleres Mediavilla.
What is milling?
He milling is a surface machining process, which is carried out with the aim of obtaining a result with a specific shape in the chosen material. It is a procedure that It is done by cutting the material with a rotary tool, which combines several movements to obtain the necessary part design.
To perform the machining the part with a milling machine, depending on how the machine is designed, it can have different movements. Movement of the rotary tool, movement of the work table in which the material is arranged or combine the two movements. The main characteristic of the milling process is the elimination of excess material, turning it into a chip that will be discarded.
History of the milling machine
The first milling machine was born in 1818 with the aim of speeding up the missile construction process in Connecticut, with the help of Eli Withney. After the creation of this first milling machine, there were changes that incorporated great advantages to the milling process of the materials.
They started to generate milling machines with different tools and disposition of materials, until giving rise to 1894 to the universal head that is still used today. This head allows to make different machining of the part with varied positions of the tool, having a multipurpose milling machine.
From the moment this machine, capable of doing precision work on metal, was born, a remarkable evolution of industrial manufacturing and machining.
The types of milling
The three basic operations milling are the cylindrical milling, the face milling and the finish milling. Each one of them being a way of working oriented to a specific result.
Cylindrical milling
In this type of process, the bur is covered with teeth along its entire circumference, each tooth acting as a tool for cutting the material. This is arranged on the cutter rotation axis, Which is placed parallel to the material willing to make this cut. These types of burs can make orthogonal or oblique cuts.
Face milling
In this type of machining, cutting edges are arranged on the periphery and front of the cutter, and it is arranged in a perpendicular to the surface. In this case, the cutter is placed in a tool holder or in the spindle of the machine, having the axis of rotation perpendicular to the table.
Finish milling
Similar to face milling in the arrangement of the cutter and the part to be modeled, with the difference that the cutter can also be arranged together with the axis of rotation in an oblique position. This type of milling is often used to make conical shaped finishes. The teeth of the cutter are arranged on the front and periphery of the cutter.
Mediavilla workshops
On Mediavilla workshops are CNC milling specialists, but we always like remember the importance and history that the industry has had since its inception. Due to our long experience, we have been able to see through our eyes the evolution of our market and the improvements that have been implemented in the manufacture and machining of the parts.
