How to avoid U-drilling problems in CNC machining, here are a few tips for you

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 perspective, the relationship between U drill and ordinary hard drill is actually similar to the relationship between machine clamp turning tool and welding turning tool. The blade can be replaced directly without regrinding after wear.

After all, the use of indexable inserts saves material than solid drills, and the consistency of the inserts makes it easier to control the size of the parts.

SO, U drill is your good choice

   ▲ The U drill can drill holes on the surface with an inclination angle of less than 30~ without reducing the cutting parameters.

   ▲ After the U drill's cutting parameters are reduced by 30%, intermittent cutting can be realized, such as machining intersecting holes, intersecting holes, and intersecting holes.

   ▲ The U drill can realize the drilling of multi-step holes, as well as boring, chamfering and eccentric drilling.

   ▲ U-Drilling When drilling, the drilling chips are mostly short chips, and its internal cooling system can be used for safe chip removal without cleaning the chips on the tool, which is conducive to the continuity of product processing, shortens the processing time, and improves efficiency.

   ▲ Under the condition of standard aspect ratio, there is no need to remove chips when using U drill to make holes.

   ▲ The U drill is an indexable tool, and the blade does not need to be sharpened after the blade is worn, which is convenient to replace and low in cost.

   ▲ The surface roughness value of the hole processed by the U drill is small, and the tolerance range is small, which can replace part of the work of the boring tool.

   ▲ 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-bottomed drill.

   ▲Using U drill technology can not only reduce the drilling tools, but also because the U drill adopts the head inlaid cemented carbide insert method, its cutting life is more than ten times that of ordinary drills. At the same time, there are four cutting edges on the insert. The cutting can be replaced at any time when it is worn. The new cutting saves a lot of time for grinding and changing tools, and can improve work efficiency by 6-7 times on average.
