With the rapid development of industry, we have a lot of CNC parts processing around us, which is enough to prove that the development prospects of this industry, or there will not be so much use, then in the process of operation. Many steps are very important. What are the effective ways for CNC processing to operate a knife?

1, click on the knife

The CnC processing equipment presses the point key on the control panel, touches the tip of the knife to the surface of the finished part, the counter is cleared, and then the initial position to be set is retreated, and then the zero is cleared to obtain the initial position of the knife. The initial position of each knife is determined in turn, and the design position is adjusted after trial processing. This method does not require any accessories and can be operated easily, but it takes a long time. In particular, every time a tool is polished, it must be readjusted.

2, the use of a knife instrument is now equipped with a knife instrument on many lathes, the use of a knife instrument on the knife can eliminate the error that is caused by the measurement, greatly improving the accuracy of the knife. Since the use of the knife instrument can automatically calculate the difference between the knife length and the knife width of each knife, and store it in the system, only the standard knife is required when processing other parts, which greatly saves time. It should be noted that there is generally no standard tool for the use of knife pairs, and the standard knife is first used when the knife is used. The disadvantage is that the use of knife instrument needs to add knife instrument auxiliary equipment, the cost is higher, loading and unloading is laborious.

3, adopt CNC tool

After the initial positioning of the CnC machining tool installation, after a period of cutting, it needs a blade grinding. The position of the knife tip reinstalled after the ordinary tool edge grinding has changed, and the knife needs to be re-aligned. The characteristic of the CNC tool is that the precision of the tool manufacturing high blade rotation is about 0.02 mm, which greatly reduces the time of the knife. At the same time, the metal layer on the blade greatly improves its durability, but this cost is also A little high.

4, use the knife block to the knife, use the self-made knife method

The simple positioning of the tool blade after grinding is easily achieved by using plastic and organic glass. However, the positioning accuracy is usually 0.2 to 0.5 mm. Single position is a fast positioning method, and then the adjustment can be used. It is very convenient quickly.
