  The commonly used CNC cutting services are mainly divided into flame cutting services and plasma cutting services, each of which has its own advantages. What is the main difference?   Flame CNC cutting service   Principle of CNC cutting service Flame cutting is the oldest form of thermal cutting. It raises the temperature of the flame through the combination of gas and oxygen. When the temperature is beyond the point of ignition or melting of the metal, cutting can be achieved. The process is accompanied by melting.   Oxygen CNC cutting service CNC flame cutting is also called flame gas cutting. After preheating the cutting place of the workpiece to a certain temperature by the heat energy of the gas flame, the cutting flow is ejected at a high speed to make it burn and give off heat. Then cutting can be achieved. Plasma CNC cutting service 1.Working principle of Plasma CNC cutting service The plasma equipment we use now is mainly air plasma. It is composed of elec...

  CNC Numerical Control milling machine in the CNC engineering services  is controlled by digitizing signals with an electronic meter.   Numerical control milling machine is a kind of automatic machining equipment developed on the basis of general milling machine. Both of them have the same processing technology and similar structure. Numerical control milling machine is divided into two categories: no - strip and strip. CNC milling machine with cutter library is also known as machining center.   Functional features of CNC engineering services In addition to the characteristics of ordinary milling machine, CNC milling also has the following characteristics: CNC engineering services are with good adaptability and flexibility of parts processing. It is able to process parts with complex contour shape or difficult to control size, such as mold parts and shell parts; CNC engineering services can process parts that cannot be processed or difficult to be processed by ordin...

  Forging is a processing method that uses forging machinery to pressure the metal blanks, which obtains certain mechanical properties, certain shape and size of forgings by the plastic deformation of the metal blanks. It is also one of the two major components of forging (forging and stamping). Forging can eliminate defects like loose as cast condition that produced in the smelting process of metal and optimize the microstructure. At the same time, the mechanical properties of forgings are generally better than the same material castings because of the preservation of a complete metal flow line. Most of the important parts with high load and severe working conditions in the related machinery use forgings except some simple shape parts can use rolling plate, profiles or welding parts.   Deformation temperature   The starting recrystallization temperature of steel is about 727 ℃. However, 800℃ is widely used as the dividing line: the hot forging is higher than 800 ℃; the f...

  As versatile a material as the copper-zinc alloy brass can be processed in just as diverse ways. Of course, it depends on the form in which it is present as a basic material and what should arise from it.   The processing of precision brass services   Among other things, the brass processing is possible in the following way: mill Rotate Drill To bend To cut Due to the material properties of brass, it is generally ideal for machining .   Precision brass services materials   1. Milling brass Nowadays, brass milling often involves the use of a  CNC milling machine , which offers very high flexibility and manufacturing precision in the production of milled parts made from this copper alloy. This is not least due to the coordinate-based computer control. With multi-axis CNC milling, significantly more complex parts can be produced with almost all workpiece geometries than would ever be possible with conventional milling. From the machining of rotationally symm...

  Stainless steel CNC machining service materials   Stainless steels are often referred to as problem materials in the field of machining. Above all, the great toughness of stainless steels and their tendency to stick is causing difficulties for many users. Stainless steels, for example, are increasingly prone to build-up edge with increasing nickel content. Also important for the assessment of machinability is the chromium content. Stainless steels are divided into three main groups: austentia, ferritic / martensitic and duplex steels. The steels of the first two groups are significantly better to cut than the latter (see Figure 1).   The largest share is held by the austenites; here can again be divided into 4 groups: In optimized for machining so-called "prodec" steels, as they are z. B. Sandvik steel under the trade name "Sanmac" and in normally machined materials, such as 1.4401 or 1.4436. In addition, there are two particularly demanding material classes in ma...

  CNC  turning china  is one of machining process. Same as other machining processed, during the cutting, part of the initial material is removed. The machinery that carry out this process is called turning machine or lathe.   Ningbo Hewcho offers metal precision CNC turned parts including carbon steel, stainless steel, aluminum, brass, and copper. This capability utilizes state of the art vertical turning machines and lathes that utilize advanced features, which allow us to turn complex, precise, geometries. We can accommodate work pieces up to 60mm in diameter and 120mm in length with tolerances to ±0.01mm. What is turning and how the production done?   What are CNC turned parts?   Turned parts are important functional components for products and can be found in many areas of today's era. Thus, with the introduction of CNC technology, the application possibilities of these turned components could be further extended. Whether the smallest micro parts for t...
