CNC Knowledge: U-Farling: one of the most commonly used tools for the treatment of holes.

Advantages of U-Diamond:

1. First of all, the difference between the U drill and the ordinary forest is that drilling U uses peripheral blades and central blades. and welding rotation tools. After all, the use of indexable blades is always saves materials than the overall hard drill, and the coherence of the blades is easier to control the size of the parts.

2. A close other laugh and a very headhole food mecipagne. Used due to the characteristics of the blade installation.

3. When you meet various materials, you just have to replace the blades of the same type and different notes, and hard drills are not so practical.

4. Compared to hard forests, the accuracy of the drill U hole is always higher, and the finish is better, especially when cooling and lubrication are not smooth, which is more obvious. The hole, but it will not work if hard drilling is hard.

Advantages of U-Drill use in CNC machining:

1. The drilling U can pierce holes on the surfaces with an inclination angle less than 30 ~ without reducing the cutting parameters.
2. Once the U-Frill cutting parameters are reduced by 30%, the intermittent cut can be obtained, such as the treatment of holes crossing, holes that cross and phase perforations.
3 and 3 US drilling can obtain a holes in several steps and can be bored, the chamfer and the eccentric drilling.
4. During drilling, drilling shavings are mainly short debris, and their internal cooling system can be used for the elimination of safe chips, without cleaning the chips on the tool, which is conducive to the continuity of Product treatment, without shortening treatment time and improving efficiency.
5. Under standard appearance reports, no need to remove the chips when drilling the holes with U drills.
6. U-Drill is an indexable tool, and the blade does not need to be refined after use.
7. The roughness value of the hole surface and the tolerance range are small, which can replace the work of certain boring tools.
8. It is not necessary to pre-dessize the central hole when using a forest U, and the lower surface of the blind holes products is relatively right, eliminating the flat-bottomed forest.
9. Use of drilling technology U can not only reduce drilling tools, but also because the U U uses a carbide insert mounted on the head, its lifespan is more than ten times that of a drill ordinary. Four cutting edges on the blade. . If you want to learn the UG programming, you can add WeChat Yuki7557 to learn

U Liaison Skills on CNC machine tools

1 and 1 When you use a U drill, the rigidity of the tooltip, the requirements of neutrality of the tool and the part are high, so that the drill U is suitable for use on CNC machines with a high power, high rigidity and high speed.
2 When you use a U-Drill, the central blade must be made of a hard blade and the surrounding blades must be made of a sharp blade.
3 and 3 when processing different materials, different inserts in the shape of a groove should be used. If the drilling length and the diameter ratio are low, choose a groove -shaped insert with greater cutting force.
4 When you use a U drill, be sure to consider the power of the machine, the stability of tightening of drill U, cutting the pressure and flow rate of the fluid and controlling the elimination effect Fleas of the U drill, otherwise it will considerably affect surface roughness and the size of the hole. Precision.
5 When you tighten the shelves in the U, be sure to have the center of U-Drills ride with the center of the room and be perpendicular to the surface of the room.
6. When you use U-Drill, select the appropriate cutting settings depending on the different part materials.
7 When cutting the UU exercises, do not arbitrarily reduce the food or do not reduce the speed of rotation due to caution, which will lead to damage the drill U or the damage of the Foret U.
8 When you use U-Frill treatment, when the blade is worn or damaged, carefully analyze the reasons and replace the blade with better tenacity or more resistant to wear.
9. When you use PRO holes in U to treat PAS holes, be sure to start treatment from large holes, then treat small holes.
10 When using a Foret U, be sure to have sufficient pressure on the cutting fluid to remove the shavings.
11 The blades used on the center and the edge of the U drill are different, so you should not use them incorrectly, otherwise the drilling rod U will be damaged.
12 During the drilling with a U drill, the rotation of the part, the rotation of the tools and the rotation of the tool and the part can be used simultaneously, but when the tool moves in linear power mode, The most common method is to use the partner’s rotation mode.
13. When processing on CNC trucks, tour performance must be taken into account and cutting parameters must be adjusted appropriately, which generally reduces low speed and power supply.

Problems that U-Drill often occurs in CNC machining:

1. The blade is damaged too quickly and is subject to rupture, which increases treatment costs.
2. A hard whistling noise is made during treatment, and the cutting condition is abnormal.
3. The Shake of the machine tool affects the machining precision of the tool-machine.

Key points to note when using U-Diamond:

1. When installing U U exercises, pay attention to the front and reverse directions, which blade is up, which blade is down, which faces the inside and facing the outside.
2. The central height of the drill U must be corrected and the control range is required depending on its diameter. If the central height is not good, the second side of drill U is it will wear, the opening will be greater, the lifespan of the blade will be shortened and it breaks easily if the little u-drill is used.
3. U requirements have very high requirements for coolant. Ensure pressure.
4. The U-drill Cutting parameters are strictly followed by the manufacturer’s instructions, but the power of the different brands of blades and machine tools must also be taken into account. .
5. U-Drill blades should be verified frequently and replaced over time.
6. Adjust the input volume as a function of the hardness of the part and the length of the overhang of the tool.
7. Do not use excessively worn blades.
8. Use sufficient and correct internal cooling liquid. The main function of the cooling liquid is the elimination and cooling of the fleas.
9. UTA stages cannot be used to treat softer materials, such as copper, gentle aluminum, etc.
