CNC Knowledge: How to avoid problems with U in CNC machining

First of all, the difference between the Drille Bit in U and the ordinary forest is that U-Drill uses peripheral blades and central blades. Tools and welding of turning 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.
So, you diamond is your good choice
▲ U drilling can pierce holes on the surfaces with an inclination angle less than 30 ~ without reducing the cutting parameters.
▲ Once the U -drill U -drill cutting parameters are reduced by 30%, an intermittent cut can be obtained, such as the treatment of holes crossing, holes that cross and phase perforations.
▲ U drilling can make the drilling of the holes in several steps and can be bored, the chamfer and the eccentric drilling.
▲ The boreholes are mainly short debris during drilling U, 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 treatment product, without shortening treatment time and improving efficiency.
▲ In the standard appearance ratio, no need to remove the fleas when drilling the holes with a U drill.
▲ U the drill is an indexable tool, and the blade does not need to be sharpened after its door, which makes it more practical to replace and is cheap.
▲ The roar value of the hole surface and the range of small tolerances are treated using drilling U, which can replace the work of certain boring tools.
▲ It is not necessary to pre-dessize the central hole when using U U drills, and the lower surface of the blind holes products is relatively straight, eliminating the flat-bottomed forest.
▲ Use the U drilling technology not only reduces the 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 an ordinary forest. The edges on the blade and insertion.
FAQ U-Drill
❶ The blade is damaged too quickly and is subject to rupture, which increases the cost of treatment.
❷ There is a hard -boiling noise during treatment, and the cutting state is abnormal.
❸ The Shake of the Machine-Outtil affects the machining precision of the machine tool.
Points to note when using U Foret
▲ When installing the U exercises, pay attention to the front and inverted directions, which blade is up, which the blade is down, which faces the inside and facing the outside.
▲ The central height of the drill U must be corrected and the control range is required depending on its diameter. The central height is not good, the two sides of the drill U will be so worn, the opening will be larger, the blade will be shortened and it will be easy to break if it is small.
▲ U Perceur has very high requirements for cooling fluid, and it is necessary to ensure that the coolant is issued by the center of the drill. Ensure pressure.
▲ The cutting parameters of the drill U 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. Generally, high speed and low power supply are used.
▲ U-Drill blades should be verified frequently and replaced in time.
▲ Adjust the input volume as a function of the hardness of the part and the length of the overhang of the tool.
▲ Do not use excessively worn blades.
▲ Use the right and correct internal cooling fluid. The main function of the cooling liquid is the elimination and cooling of the fleas.
▲ U-Drills cannot be used to treat softer materials, such as copper, gentle aluminum, etc.
D drill skills in 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 U-Drill, be sure to consider the power of the machine’s pin, stability of tightening in U-Frill, reduction in pressure and flow rate and will control the effect of elimination of U-Drill chips, otherwise this will considerably affect the roughness and size of the surface of the hole surface.
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 exercises in U, do not arbitrarily reduce the food or do not reduce the speed of rotation due to caution and fear, which will lead to damage the drip u or the damage of the drill in 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 you use a U drill, 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.
