Discussion of the influence of machining process on the machining accuracy of parts and control

Overview of machining process Based on the mechanical parts as well as workpiece manufacturing period, the relevant machining process method is taken to change the blank, and processing is carried out to further process the fit between the blank and the part. From the practical work point of view, based on the implementation of mechanical machining process during the processing of the rough grinding as well as parts processing accuracy requirements are very demanding. Analysis of the impact of machining processes on the machining accuracy of parts Intrinsic influencing factors …

What are precision machined parts

Have you ever wondered how a machine shop makes precision machined parts, such as engine parts? These parts are certainly not produced by hand. In fact, machine shops use a process called “precision machining”. Precision machining produces critical components for almost every piece of equipment we use in our daily lives. Precision machined parts have transformed industries such as aerospace, automotive, power transmission equipment and other manufacturing industries. If you need some precision machined parts? Then you better know know what precision machining is and how to use it to …

What is the difference between a lathe and a milling machine?

Lathe is generally processing shaft, sleeve, disk, pad and other parts, generally horizontal lathe is the main, of course, large lathes also have vertical and other forms, lathes generally have tool holders, used in accordance with the tool, processing form is generally tool feed movement, the main motion for the workpiece rotary motion Turning used to process rotary parts. The parts are clamped on the spindle of the machine tool by three gripping chucks and rotated at high speed, then the turning tool is used to follow the bus line …

What is the difference between CNC milling machine and CNC lathe? What are the advantages?

　CNC milling machines and CNC lathes are two of the most commonly used CNC machines today. When machining, the process of milling and turning looks very similar (i.e. metal removal). However, there is actually a big difference between the two. 　Turning means machining on a lathe. The machining principle is that the workpiece is rotated and the tool is fixed. During machining, the blanks or workpieces are first fixed to the rotating spindle with a fixture. As the spindle rotates, a turret containing the tool controls the movement of the …

The difference between 3+2 positioning machining and 5-axis cNC machining

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 essentially the implementation of a three-axis function at a specific angle (i.e. “positioning”). Simply put, when the machine is rotated at an angle, machining is performed in a normal 3-axis fashion. What is 5-axis simultaneous machining According to ISO regulations, …

What are the selection requirements for the shaft machining process?

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 also be made hollow and with welded or forged flanges. For complex shaped shafts, casting can be used. Shaft blank selection For self-locking nut light shaft or shaft section with little change in diameter and less important shaft, rolled round …

What makes 5-axis machining?

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, is a major resistance to the popularity of five-axis CNC technology. Many domestic manufacturers from abroad to buy five-axis CNC machine tools, due to technical training and services are not in place, five-axis CNC machine tools inherent functions are difficult …
