Q: Can twist drills drill through wall tiles?: To use the electric drill tile or impact drill with drill, drill bit to use glass with water, careful operation, drilling speed from slow growing fast.

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: What is a square hole drill and can be machined square hole?: The three vertices of an equilateral triangle as the center, edge radius at the apex on the side arc, get leelo triangle. As it is easy to prove that the triangle leelo properties, its width is equal to the structural length of the equilateral triangle. The length of the triangle leelo width within the square rotates, each corner of the path traversed basically is a square.

Q: What's the difference between a drill bit and a drill bit?: That bit, drill iron is generally the middle point (force, wear to feed); wood drilling is generally three sharp edge, high in the middle and low on both sides (soft wood, such as drill faster, on both sides of the edge can also make the drill mouth flat appearance, also known as plate drilling).

Q: CNC machine tools I use 6.5 bit drilling out is 6.7, what method can be solved?: Also, bit clamping and grinding will also affect the drilling size to varying degrees.Remedy is:1, the size of the hole strict requirements of the workpiece, you can drill after the hinge.2, the hole size requirements are not too strict, with 6.5 or 6.6 drill directly drilling. In mass production, the first workpiece must be measured and checked.

Q: Deep hole refers to the diameter of drill bits more than times, called deep hole: In machining, the hole with a hole ratio greater than 6 is usually called a deep hole. In deep hole drilling, it is difficult to get rid of heat and chip, and it is easy to bend and vibrate because of the poor rigidity of the drill rod. Cooling and cooling systems are usually used to solve cooling and chip removal problems. The classification of deep hole drilling is divided into two types according to chip arrangement: chip and chip. There are 3 kinds of chip removal drill, deep hole flat drill and deep hole twist drill. The internal chip removal is divided into BTA deep hole drilling, jet drilling and DF deep hole drilling.

Q: What steel blade drill bit, hardness above 60: A diamond bit is a drill bit for cutting edges. The drill bit is an integral bit, the whole drill bit has no moving parts, the structure is relatively simple, with high strength, high wear resistance and impact resistance, it is one of the three new drilling technologies in the world in 1980s. Field use shows that the diamond bit in the soft - hard strata drilling, have the advantages of high speed, more footage, long service life, stable operation, less accidents, downhole wellbore quality etc.. The diamond bit not only can be used for a long time, but also can be reused. The diamond bit recovered from the factory can be used almost as well as the diamond bit produced by the factory. It can save drilling cost in large amount.

Q: How do you drill a drill?: 2, drill clockwise in the same direction, drilling tail down about 10 degrees angle, sharpening;3, drill once rotated 30 degrees angle or slightly larger, pay attention not to sharpen all other cutting edge, grinding two or three times;The 4 supporting point does not change, and the drill rotates 180 degrees, with the same method sharpening all other cutting edges;5, after grinding, the drill will be vertical (to make it natural droop), and hold it in hand, check whether the grinding bit is symmetrical with its center line;In case of asymmetric grinding, the angle between the cross blade and the cutting edge should be 50 degrees --55 degrees;

Q: How much bit should we use to punch the M5 hole? Tapping with Duodasi attack? Why use 8.3 drill bit in the hole of M10? How do you know how big it is to punch and tap?: If the material soft bottom be slightly smaller, so hard to be slightly larger. As the aluminum tapping hole to drill small, alloy steel tapping will be slightly larger. M5 has a pitch of 0.8, so use 5-0.8=4.2's drill. The pitch is 1.5 M10, normal use 8.5 bit, if 8.3 words may be used as the material of soft, normal bit will lead to larger hole.

Q: Drill hammer type matching specifications: Hard alloy electric hammer drill body made of high quality alloy steel, the knife head is welded with hard alloy. Matched with various electric machine, concrete, brick and other building materials for hard drilling. The utility model is a drilling tool with wide use and high efficiency in the construction and installation industry.
