Choose the right U drill model: make sure it matches the machining center

The U drill itself is used for roughing holes, and the tolerance is normal between -10--+10. If you want to control the error, there are two ways. First, provide the specific size of the finished hole before buying the knife, let the manufacturer help you try the knife, and use it for you after meeting the requirements. Generally, if I choose for my customers, I will choose a 15.9 U drill, and then let the factory try the knife, and it will be almost 16 when I come out. The second method is to buy a U drill with a higher precision, with a tolerance of -5--+5. Of course, the price of this kind of knife is much more expensive, because the scrap rate is too high, this part of the cost must be added in the factory. When choosing a U drill, choose the shortest tool while meeting the processing requirements, which can also reduce the error. The type of cutting fluid, the material of the blade, and the processing speed will all affect the accuracy. You must adjust it according to the actual situation.

Install the U drill correctly: follow the steps in the operation manual

The correct installation of the U drill is an important task, which is directly related to the use effect and life of the tool. Make sure you have read and understood the operation manual of the U drill, which is an indispensable reference during the installation process. The operation manual will list the various parts of the U drill and its installation sequence in detail. Be sure to follow these steps.

Before starting the installation, check whether all the parts of the U drill are complete, including drill bits, chucks, drive shafts, etc., to confirm that there are no missing or damaged parts. Follow the instructions in the operation manual and assemble the various parts of the U drill one by one. During the assembly process, pay attention to keeping the parts clean to avoid dust and impurities affecting the performance of the U drill.

When installing a U drill, special attention should be paid to the degree of fastening of the chuck. The chuck needs to be firmly fixed to the drill bit to prevent it from falling off during use. At the same time, make sure that the connecting part of the drive shaft and the U drill are closely matched to avoid loosening during use.

After completing the assembly of the U drill, conduct a trial run to check whether the U drill can work normally. If any abnormalities are found, stop using it immediately and check the operation manual for omissions or errors during the installation process. The correct installation of the U drill is the basis for ensuring its efficient and safe operation.
