Q:How does the CNC lathe drill center to detail?
First use the center drill, the first smooth, the second pull, the Dutch, and the drill to the center of the workpiece drilling a small hole! The center drill is a CNC machining center tool used for drilling end faces, in the center, CNC drill hole clamping workpiece in NC lathe lathe, and then it will be used in drill hole slowly close to this method can be used to do, this method is much higher than the first kind of precision tool.
Q:Can twist drills drill through wall tiles?
A drill bit (Drills) is a tool used to drill through holes or blind holes in solid material and to expand existing holes. The commonly used drills are mainly twist drills, flat drills, center drills, deep hole drills and casing drills. Reaming drill and countersink drill is not in solid material drilling, but it is also customary to put them in a bit.
Q:How big is the smallest bit?
A drill bit (Drills) is a tool used to drill through holes or blind holes in solid material and to expand existing holes. The commonly used drills are mainly twist drills, flat drills, center drills, deep hole drills and casing drills. Reaming drill and countersink drill is not in solid material drilling, but it is also customary to put them in a bit.
Q:Grinding the drill bit, how can grinding, and the method of quick crash is what ah?
Deviation angle of drill shaft." Here is the relation between the axis of the drill bit and the surface of the wheel. "Frontal angle", that is, the top angle of 118 degrees + 2O half, about 60 degrees, this position is very important, directly affect the drill point size and the main cutting edge shape and cross blade edge angle. Often. One and two refers to the relative position of the drill before sharpening, and the two should take overall consideration, not to set aside the edge of the knife and ignore the angle of setting or to lay the oblique axis and ignore the blade. These errors are often present in actual operations. At this point, the drill is ready for contact with the wheel in place of the correct position.
Q:What brand of drill iron?
The key of the bit selection is not the brand, but the choice of the drill bit.
Q:Why is the drill angle 118 degrees?
It is the projection angle of the two main cutting edges in the middle section. The smaller the vertex angle is, the longer the main cutting edge is, the load on the cutting edge of the unit decreases, and the axial force decreases, which has a strong axial stability to the bit. And the knife edge at the outer circle is increased, which is beneficial to dissipate heat and improve the durability of the cutter.
Q:What causes the drill bit to break at the end of the hole?
Small bit not used high speed, with small feed amount.A small drill can withstand torque is small, the use of high speed with a small amount of feed, can reduce the small rotating cutting output, so as not to drill to bear large torque.
Q:What's the difference between a deep hole drill and an ordinary bit?
Ordinary drills are of relatively low hardness, impact resistance and wear resistance. The drilling accuracy, drilling speed and the drilling speed of conventional drills can not be compared with those of deep hole drilling.
Q:When tapping M4, M5, M6, M8 and M10, how big bits of drill (ordinary steel) are used?
Extrusion tap:Screw - pitch: D=d1-0.49P P = 2. In the case of M10x1.5, hole size D=10-0.49 * 1.5=9.27. (recommendation 9.3)Screw - pitch: D=d1-0.42P P = 0.8. In the case of M3x0.5, hole size D=3-0.42 * 0.5=2.79. (recommendation 2.8)Therefore, cutting tap hole were recommended as follows: 3.3, 4.2, 5, 6.8, 8.5
Q:M3 threaded hole. The bottom should choose large diameter drill bit
The bottom of the thread hole of the above M3 is the standard diameter of the drill bit made of ordinary materials. Of course, the actual production operation because the M3 screw mechanical properties of various materials is not the same as the processing of the material properties through appropriately adjusting, processing, such as M3 stainless steel threaded hole, must be to increase the diameter of the bottom hole processing, because the mechanical properties of stainless steel and ordinary materials are not the same. Stainless steel material hardness high, heat dissipation is poor, the reason of higher plastic, bottom diameter with a diameter of 2.7 bits. So in the actual operation, the operator should be through different material properties, adjust the threaded hole diameter of M3, so as to prepare for the next tapping.
