Take stock of 7 common machining methods, let's take a look!

The form of machining varies according to the requirements of different material workpieces and products. The traditional machining method is the car, pliers, washing, planing and grinding that we often hear. With the development of mechanical technology, in terms of machining, electroplating, wire cutting, casting, forging and powder processing have also appeared.

So what are the forms of machining?

1. Turning

Turning is mainly due to the rotation of the workpiece, and the workpiece is cut into the required shape by the turning tool. When the tool moves along the parallel axis of rotation, the inner and outer cylinders can be obtained. The formation of the cone is that the tool moves along the diagonal line intersecting with the axis. The formation of a rotary surface is a copying lathe or CNC lathe that controls the feed of the tool along a curve. Another kind of rotary surface production, is the use of forming tool, transverse feed. In addition, machining thread surface, end plane and eccentric shaft can also be turned.

2. Milling

The milling process mainly relies on the rotation of the tool. Milling is divided into horizontal milling and vertical milling, and the plane of horizontal milling is formed by the edge of the outer circular surface of the milling cutter. The end mill is formed by the end edge of the milling cutter. In order to obtain a higher cutting speed and improve productivity, you can increase the speed of the milling cutter. However, due to the cutting and cutting of the cutter teeth, the impact is formed, and the cutting process is easy to produce vibration, thus limiting the improvement of the surface quality.

3. Planing

Planing is mainly the cutting tool to do reciprocating linear motion to cut the workpiece. As a result, the speed of planing is relatively low, resulting in lower productivity. However, the accuracy and surface roughness of planing are more stable than the results of milling.

4. Grinding

Grinding processing mainly relies on the grinding wheel and abrasive tool to process the workpiece, and relies on the rotation of the grinding wheel. When grinding wheel is grinding, the abrasive particles on the grinding wheel mainly have three functions of cutting, cutting and sliding on the workpiece surface. The abrasive particle itself is gradually blunted from sharp, so that the cutting effect becomes worse and the cutting force becomes larger. Therefore, after grinding for a certain time, it is necessary to use diamond turning tools to trim the grinding wheel.

5, tooth surface processing

Tooth surface processing is a new processing method, which is divided into two categories: one is forming method, and the other is developing method. The forming method mainly uses the ordinary milling machine for processing, and the tool is the forming milling cutter, which requires the rotary motion and the linear movement of the tool. The commonly used machine tools for generating tooth surface processing are gear hobbing machine, gear shaper machine, etc.

6, complex surface processing

For the processing of complex surfaces, CNC machine tools come in handy. The cutting of three-dimensional surface mainly adopts the method of contour milling and CNC milling or special machining method. Copying milling must have a prototype as a model. During processing, the ball head copying head always contacts the prototype surface with a certain pressure. Focus on us: Mechanical engineers, focusing on the mechanical industry, professional, career information sharing, serving millions of engineers in the manufacturing industry. The motion of the copying head is transformed into inductance, and the motion of the three axes of the milling machine is amplified to form the trajectory of the cutter head moving along the curved surface. Milling cutters are mostly ball-end milling cutters with the radius of the contour. The appearance of numerical control technology provides a more effective method for surface machining.

7, special processing

Special processing is different from traditional machining machining, special processing can use physical (electrical, acoustic, optical, thermal, magnetic), chemical or electrochemical methods to process the workpiece material, so that the workpiece into the shape we need.

In the selection of machining methods, we must consider many aspects and choose the right method, so that the production of both precision and quality can be guaranteed. With the continuous development of science and technology, the form of mechanical processing is also increasing, in addition to the several common ways introduced in the article, there are many processing methods.
