With the rapid development of industry, there are many CNC parts processing around us, which is enough to prove that the development prospect of this industry is still OK, otherwise there will not be so many in use. So in the process of operation, many steps are very important. What are the effective methods of CNC machining tool setting operation?
- Jog the tool setting hair
Press the zero point (z) of the initial tool, and then press the zero point and Z key on the surface of the designed tool to clear the initial position of the workpiece, and then press the zero point and Z key to get the initial position of the tool. Determine the initial position of each cutter in turn, and then adjust to the accurate design position (starting point) after trial processing. This method can be operated easily without any auxiliary tools, but it takes a long time. Especially, the tool must be readjusted once every grinding.
- Tool setting instrument
Now many lathes are equipped with tool setting instrument. The error caused by measurement can be avoided by using the tool setting instrument, which greatly improves the accuracy of tool setting. Because the tool setting instrument can automatically calculate the difference between the length and width of each knife, and store it in the system. When processing other parts, only the standard tool is needed, which greatly saves time. It should be noted that there is no standard tool for tool setting with the tool setting instrument. When setting the tool, first set the standard tool. Its disadvantage is that the tool setting instrument needs to be equipped with auxiliary equipment for tool setting instrument, which has high cost and laborious loading and unloading.
- Use CNC tools
After the initial positioning of CNC machining tools, wear occurs after cutting for a period of time and needs to be sharpened. After grinding, the position of the re installed tip of the common tool has changed, and it needs to be re aligned. The characteristic of CNC tool is that the manufacturing accuracy of the tool is high, and the repeated positioning accuracy after the blade is rotated is about 0.02mm, which greatly reduces the tool setting time. At the same time, the blade is coated with metal layer (SiC, tic, etc.) greatly improves its durability, but the cost is also a little high.
- Use the tool setting block to set the tool, and use the self-made tool setting method
The simple tool block made of plastic and plexiglass can easily realize the repeated positioning after tool grinding, but the positioning accuracy is poor, which is usually 0.2 ~ 0.5mm. Single tool is a fast positioning method, and then it can be adjusted quickly and conveniently.
