The difference between U drill and ordinary drill


Ningbo Rongke Maite NC Tool Co., Ltd. is wholesale deep hole drills manufacturers. Company has been concentrating on researching and producing hole making tools, we have technology cooperation with many universities.

.
  1. First of all, the difference between U-drill and ordinary drill is that U-drill uses the peripheral blade and center blade of the blade. From this point of view, the relationship between U-drill and ordinary hard drill is actually similar to the relationship between machine-clamped turning tools and welding turning tools , the blade can be replaced directly without regrinding after wear. After all, using indexable inserts saves material over solid hard drills, and insert consistency makes it easier to control part size.
  2. The rigidity of the U-drill is better, and a high feed rate can be used, and the processing diameter of the U-drill is much larger than that of the ordinary drill, and the maximum can reach D50~60mm. Of Of course, the U-drill cannot be used due to the characteristics of the insert. is too small.
  3. When the U drill encounters various materials, it only needs to replace the blades of the same type and different grades. The hard drill is not so convenient.
  4. Compared with the hard drill, the precision of the hole drilled by the U drill is still higher, and the finish is better, especially when the cooling and lubrication are not smooth, and the U drill can correct the position accuracy of the hole , but the hard drill will not work. Now, you can use the U-drill as an over-the-top rifle.

 

The advantages of U drill in CNC machining:

  1. The U drill can drill holes on surfaces with an inclination angle less than 30~ without reducing cutting parameters.
  2. After the cutting parameters of the U drill are reduced by 30%, intermittent cutting can be realized, such as machining intersecting holes, intersecting holes, and intersecting perforations.
  3. The U-drill can realize the drilling of multi-step holes, as well as boring, chamfering and eccentric drilling.
  4. Most of the drill chips are short chips during U-drill drilling, and the internal cooling system can be used for safe chip removal, without the need to clean the chips, which is beneficial to the processing continuity of the product, shortens the processing time, and improves the efficiency.
  5. Under the condition of standard aspect ratio, there is no need to remove chips when using U-drill.
  6. The U-drill is an indexable drill. No sharpening is required after the blade is worn out. The replacement is convenient and the cost is low.
  7. The surface roughness value of the hole processed by the U drill is small and the tolerance range is small, which can replace the work of part of the boring tool.
  8. There is no need to pre-drill the center hole when using the U-drill, and the bottom surface of the processed blind hole is relatively straight, eliminating the need for a flat-bottom drill.
  9. The use of U-drill technology can not only reduce the number of drilling tools, but also because the U-drill adopts the method of inserting carbide inserts on the head, and its cutting life is more than ten times that of ordinary drills . At the same time, there are four cutting edges on the insert. When the blade is worn, the cutting can be replaced at any time. The new cutting saves a lot of grinding and replacement time, and can improve the work efficiency by 6 -7 times on average.
