cnc milling is one of the modern and specialized methods in the field of industrial and functional parts production and is used in many parts making industries. This machine performs milling on metal to plastic parts using a central computer with a pre-prepared work program.
CNC milling machine is an intelligent computerized device that can do without the intervention of human hands. perform all types of parts and cuts, from simple to complex, on all types of metal to plastic and wooden surfaces in the fastest time. According to the accuracy and fineness of the machine and the type of clean cut, all cutting and milling parts It can be ready to be sent to the market without the need for assembly steps. However, its application type is different in different parts making industries.
The operation of the milling machine is based on the basis and number. Based on the pre-prepared design with 3D software, the operator introduces the volumetric design to the machine, and the machine starts cutting and turning the piece in three axes X, Y, Z according to the given criteria and scale.
In the old manual milling machine, only the operator could cut and mill on one axis, and it was practically impossible to rotate and create steps. But in the CNC milling machine, due to all kinds of moving accessories, milling operations for grooving, threading and stepping can be easily performed on the desired part.
Principles of Working with CNC Filling Machine
Generally, the initial 3D modeling of the design is delivered by the design engineer on a CAD format. The component engineer prepares for the CNC milling machine based on the type of angle size, diameter or body design or any type of groove and screw and other specifications. It is ready to work and cut with a CNC milling machine. The execution of the milling operation varies depending on the type of design and model and the cutting that is done.
In the lathe, there are two X and Z axis manual models, in which the Z axis of the cutting machine has a rail to move to the left or right. And in the X axis of the lathe, three systems of spindle operation, or the same as chip removal, were performed. But the Y axis, which provides the ability to move forward and backward, was not there to design and carve a 3D model.
Types of CNC milling machine
Face milling machine
It is a modification of that machine (Face milling), which is called a state where the axis of rotation of the cutting tool works perpendicularly to the target piece. This method is used to create a cut on smooth and flat surfaces.
Simple milling machine
Its modification (Plain milling) is called flat milling. It is also called the level. In this method, the cutting machine performs the cutting operation completely parallel to the surface of the part. According to the type of cut and the field of application of the metal, the depth of cut and the size of the piece can be precisely milled. This method makes it possible to use for narrow and wide cuts. Angular milling machine is its modification (Angular Milling). It is used to create and cut parts that have angles and arcs. From this device, he made gear cutting, groove cutting to design and produce parts such as knives or surgical blades. The cuts of this machine are made with angles of 45 to 60 degrees. Form milling machine is its modification (Form milling). This machine is able to grind all irregular, lined and grooved surfaces even with curved and smooth body. The working form milling machine is capable of cutting and turning all kinds of convex, concave, round, roller and circular parts.
