Q: Woodworking drills, classification, woodworking drills are those categories, the more specific the better: At present, the international woodworking drill popular three awl auger drill bit, drilling ladder.Three sharp woodworking drill easy to locate, high-speed cutting, the wood powder, usually used to process small holes.

Q: Relationship between pump pressure and bit pressure drop: Classification and nomenclature. For example, according to the drive method can be divided into electric pumps and water turbine pumps; according to the structure can be divided into single-stage pumps and multi-stage pumps; according to the use of boilers can be divided into feed water pumps and metering pumps; according to the nature of the transmission fluid can be divided into pumps, pumpsAnd mud pumps, etc.. In accordance with the non axial structure, can be divided into linear pumps and traditional pumps. It adopts the principle of magnetic suspension and the hydraulic structure of spiral ring to realize liquid propulsion, that is, to cancel the shaft, to cancel the shaft connection, and to cancel the seal structure of the shaft. After starting, the electric current is transformed into a magnetic field, and the magnetic field force drives the spiral ring to move, namely, the spiral ring promotes the liquid advance.

Q: How do you determine the speed of the drill? Is there any standard?: Large hole processing speed is not too fast, too fast, easy to make the head color (coke), resulting in turn annealing, eventually scrapped;Small rotor speed should be fast forward to the amount of slow, fast, easy to break, turn around, pay attention to crumbs.

Q: What method should we pay attention to when drilling small holes and long holes in plain drills?: Coolant added a lot, although the cooling effect is good, but it will make drilling cuttings are not easy to row out. Just use a brush with a coolant, and when the drill is lifting the cuttings, brush some of the coolant on the drill. Each time the drill is drilled down, do not enter too much at once. Especially in the hole drilling more and more deep, but also frequently drill bits, cleaning up drilling chip.

Q: Angle action and characteristics of standard twist drill: The main deviation angle is RM, and the main angle is the angle between the tangent of the main cutting edge and the feed direction of the m. The base surface of the twist drill is the plane at which the main cutting edge is selected, including the axis of the drill bit. The bit is not the main cutting edge through the axis line, so each point on the cutting edge of different base, the main angle points are also different. When the angle of grinding, the main angle can be determined. The main deflection angle and the vertex angle are two different concepts.

Q: How can the 1 millimeter drill be worn?: Less grinding, orifice in three edge or pentagon, look carefully, really half a certain degree of difficulty, teachers see the grinding action, do not blindly grinding, students often have yet to settle on the edge by grinding the start on the wheel, too large angle drill in drilling look, all kinds of grinding defects of twist drill. The students have not mastered the sharpening skills and techniques, according to the methods and skills of practice summed up in simple formulas form explanation and demonstration, students tend to understand, the other main blade drill was destroyed, is less grinding in better control of miss the point, size, angle of the diagram. Look calmly. And after sharpening the edge of the blade.

Q: What is the geometric angle of the drill bit?: The commonly used bit, roughly divided into rolling twist drill, full grinding drill, is divided into straight shank drills, taper shank drill and 1/2 drill, double auger, single head, short drill center drill, six angle shank drill, electric hammer drill, impact drill, the material can be divided into 4241# and 4341#. 9341#, M35, M42, 6542#, and alloy etc..

Q: What brand of drill iron?: There are many kinds of drill bits, mainly based on their different uses, which is what to drill and what kind of drill bits to use.

Q: For 25 bit is much with the expansion screw: Fastener consultant Yu Wenlong believes that their best related information, come online is always false, meet the random response, smatter, is simply false or deceptive directly mislead you, even hurt you. Light product quality is not qualified, serious person should be fined. Of course, the fastener consultant Yu Wenlong believes that if the strength of a fastener, please refer to your technical consultant, to grasp the direction of enterprise development, product positioning, customer orientation is a good choice.
