In the process of CNC machining , the selection of the tool is very important. The choice of the tool determines the quality of the workpiece, because there are certain requirements for the tool performance of CNC machining. Different machining parts and different batches determine the choice of tools. Let's take a look at the factors that affect the choice of CNC machining tools. cnc machining (1) Production batch From the processing cost, there is a certain influence on the selection of the tool. If it is a certain part of mass production, special tools are needed, which is relatively cost-effective. However, if the tool is used to produce a single piece or a small batch, the tool is relatively expensive, so it is more appropriate to use a standard tool. cnc machining (2) Machine type The effect of the CNC machine used to complete the process on the selected tool type. High productivity tools can be used to ensure the rigidity of the workpiece system an...

In the process of CNC machining , the deformation of the workpiece is very common. If the precision is not enough, it can be used for secondary processing. However, the deformation of the workpiece has to be rebuilt. The deformation of the workpiece is a difficult problem. The best solution is to eliminate the deformation of the CNC machining parts from the root. Let's take a look at how the deformation of CNC machined parts is caused. cnc machining  1. The influence of the material and structure of the workpiece on the deformation of the workpiece The amount of deformation and the complexity of the shape, the long width and the wall thickness are proportional to the rigidity and stability of the material. It is generally necessary to reduce the influence of these factors on the deformation of the workpiece when designing the part. Especially in some large parts and structures, it is necessary to make the structure reasonable. In the process of machining, it is necess...

CNC turning is on the lathe, using the rotary motion of the workpiece and the linear or curved motion of the tool to change the shape and size of the blank, and to meet the requirements of the drawings. CNC turning CNC turning is a method of cutting a workpiece on a lathe using a workpiece relative to the tool rotation. The cutting energy of CNC turning is mainly provided by the workpiece rather than the tool. CNC turning Turning is the most basic and common cutting method, and it plays an important role in production. Turning is suitable for machining rotary surfaces. Most workpieces with rotary surfaces can be machined by turning, such as inner and outer cylindrical surfaces, inner and outer conical surfaces, end faces, grooves, threads and rotary forming surfaces. The tools used are mainly turning tools. CNC turning Among all types of metal cutting machine tools, lathes are the most widely used category, accounting for about 50% of the total number of mach...
