Metal milling: about the process technology, types and methods

The creation of metal parts requires the use of special equipment that changes the shape of the raw material. A modern company uses many metalworking methods, and one of the most popular is milling.

You can order milling work in Dnipro at TD TAM by calling the phone numbers listed on the website.

Regardless of the complexity of the milling machine design, the main element of the machine is a cutter – a wheel with sharp teeth that rotates at high speed.

Metal machining in the form of milling is used to create asymmetrical parts with a complex structure. Metal milling is used in many areas of manufacturing. Milling is sometimes performed for secondary processing of the product when it is necessary to correct defects or make additional recesses.

This process depends on the orientation of the main element of the equipment. There are several types of processing of this type.

Types of milling

Milling can be done horizontally or vertically. The choice of method depends on the straightness of the spindle and the method of fixing the material. Today, many milling companies now have machines for milling, where the position of the spindle can be changed. This makes it possible to wrap the material under different tufts.

The cutter is available as an end cutter, end cutter or shaped cutter.

Tortsev needs to work with large-area material. In this type of cutting the metal occurs in the plane of the wrapping of the cutting element and directly in the wrapping of the cutter.

With a special end mill, you can create slots, openings, gutters and other folding elements. This method allows you to remove obstructions from the folding structure.

The shaped milling cutter is used for the production of bevels of folding geometric shape. This method can also produce gears, worms and other parts. To achieve this type, it is necessary to install special shaped milling cutters with a fine guard.

The peripheral method makes it possible to create a cutting edge along the cutter stake. This technology is used for cutting a folding groove or using a power milling method.

Milling method

Directly wrapping the cutter means the milling method, which is incidental and sharp.

The sintering method is characterized by excellent productivity and high processing accuracy. The only downside is that the surface of the part may be a bit rough. This technology itself will be introduced at the stage of rough processing of metal material.

The finishing process is completed using additional milling. In this case, you have prepared something to “pass” under the cutter. This approach makes it possible to obtain a perfectly smooth surface.

The process of metal processing using the technology described can be divided into several stages:

1. Fixed and released to the virus. The triviality of this stage lies in the dimensions of the virus.
2. The hour required for cutting. It is possible to recover time expenditures by dividing the contribution according to the speed of supply of material.
3. I’ve been idle for an hour. Vikonuє dii, not related to the vikoristannya of milling equipment.
4. Replacing the cutter. Some cutters must be replaced if they have lost their effectiveness.

What is chemical milling?

If the master wants to apply the scale, the scale is written on the surface of the virobe, you can use chemical milling technology. This method is also suitable for changing the diameter of cylindrical components and the thickness of the walls of metal parts.

The chemical method makes it possible to create convex and small spots on the outside of the workpiece. To create a curved image, a special varnish is used, and to form a curved image, a crimping method is used.

Chemical milling is carried out using vicoristic concentrated acid or water. To prevent etching of aluminum, you can use sodium hydroxide.

It is important to understand that milling metal using additional chemicals takes a lot of time. After processing, it is necessary to carry out cleaning, polishing, rinsing and other activities. In any case, this technology is characterized by efficiency.
