Turning and milling are two typical types of cutting operations. Cutting is a method of using tools to cut and machine various materials such as metals, plastics and wood into a desired shape. It is a processing method to remove chips from the base material and belongs to "removal processing".
Most of the workpieces with rotary surfaces can be machined by turning, such as internal and external cylindrical surfaces, internal and external conical surfaces, end faces, grooves, threads and rotary forming surfaces. The tools used are mainly turning tools. The "milling process" is to fix the blank and use the
What is 3+2 positioning machining 3+2 machining technology is also known as positioning 5-axis machines because the fourth and fifth axes are used to determine the orientation of the tool in a fixed position rather than for the duration of the machining process. The principle of 3+2 positioning machining is
Multi-axis CNC machining CNC milling involves the use of rotating tools to remove material. Either the workpiece remains stationary and the tool moves onto the workpiece, or the workpiece enters the machine at a predetermined angle. The more axes of motion a machine has, the more complex and faster the
Shafts are generally manufactured from rolled round steel or forgings by cutting process. Shafts with small diameters can be manufactured from round steel bars; for important, large diameters or shafts with large variations in step diameter, forgings are mostly used. To save metal and improve processability, large diameter shafts can
Characteristics of the part and processing difficulties. The number of gear teeth is 400, the modulus is 0.5mm, and the gear accuracy grade is 6. This part length-diameter ratio of up to 1:67, belong to the thin-walled parts, it has the following characteristics. (1) the part wall thickness is not
The programming regulations of CNC machining require not only the calculation of linear motion, but also the coordination of the stroke inspection of its rotation angle, the rotational motion of props or the error checking of non-linearity and other calculations related to it according to the production needs, and the
The operation and programming skills of 5-axis CNC machining are closely related, and if the user adds special functions to the machine, the programming and operation will be more complex. Only repeated practice, programming and operation personnel can master the necessary knowledge and skills. Experienced programming, the lack of operators,
Five-axis machining, as the name implies, is a mode of CNC machine tool machining. Using linear interpolation motion of any five coordinates in X, Y, Z, A, B, C, the machine used for 5-axis machining is usually called a 5-axis machine or 5-axis machining center. But do you really understand
CNC machine tools to complete the machining process has incomparable characteristics of ordinary machine tools, such as substantially improve productivity, with higher machining accuracy and automation, etc. With the rapid development of automotive, aerospace, aviation, national defense and other industries, as well as the application of new materials such as
In the machinery manufacturing industry, there are many special parts that need to be produced and processed, among which slender shaft parts are widely used in the petroleum machinery industry, automobile parts industry, and high-speed dynamic vehicle industry. Because of this kind of workpiece easy to bend, heat deformation, as
A shaft with a ratio of length to diameter greater than 25 is called a slender shaft. For example, screws and light bars on lathes. Due to the poor rigidity of slender shafts, cutting force, cutting heat and vibration during turning, it is easy to deform. And machining errors such
