Q:What drill can be used to break through high strength stainless steel plates?
Hard alloy, such as tungsten carbide and the like, or the surface of hard coating, such as titanium carbide can be, high strength stainless steel, hardness is not very high, a lot can be.
Q:What drills are used in stainless steel drilling?
Stainless steel cutting drill martensitic stainless steel 2Crl3, just wear E-E chipbreaker; while drilling of lCrl8Ni9Ti austenitic stainless steel, but also need additional A-A chipbreaker.The characteristics of S type carbide drill is: chisel edge can reduce the axial force of 50%; a former angle is positive, sharp edge; web thickness increases, increase the drill rigidity; two jet cutting fluid hole; arc cutting edge and the chip distribution is reasonable, easy cutting into pieces. In order to facilitate discharge.The characteristics of transposition of cemented carbide drill for shallow holes is equipped with two front end of the drill bit is asymmetric convex triangular blades, different parts of the chip removal hole, automatic centering, straight hole, and the cutting length is short; blade rake face is provided with a plurality of pit groove cutting, good performance especially reliable chip breaking, the chip is consistent with the broken chip cooling; the cutting fluid is directly sprayed to drilling surface, improve the cooling effect, chip very smooth; especially according to the hard alloy blade with different grades of workpiece materials, cutting speed is 80 ~ 120m/min, drilling is very brisk.
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.
Q:How do we calculate the length of a drill for a bored pile drill?
There are two main types of drilling rigs: rotary drilling machine and impact drilling machine. The bit of rotary drill is divided into three kinds of scraper drill: suitable for quicksand and silt layer. Only the diameter and weight limit, no length limit cone drill: suitable for soft stone and hard soil. There is no length limited hob drill: suitable for hard rock layers. There are weight limit and hob arrangement, hardness requirements above, there is no drill length requirements. Impact drill: it is to use the weight of the drill to squeeze the soil into the hole, and the hole of the rock is also to use the bit itself to destroy the rock structure surface into holes. Only the weight on bit (according to the requirements of classification of rock hardness determine bit weight, diameter of 2-2.5 meters in the drill hole, the weight of at least 10 tons; 1.5-2 meters, bit weight of about 5 tons, 1.5 meters below 3 tons. For impact drilling, the length of the drill has a certain requirement, usually 1.8-2.5 meters high. Because the longer the drill bit, the stronger the impact drilling guidance function, the smaller the possibility of partial hole, hammer and hammer, the higher the standard of drilling. There are no rules and regulations, and you can succeed by experience.
Q:Is there a standard for drilling errors due to machine tool shaking?
Is the drill drill a positive or negative deviation, or is it bigger or smaller?. Bit wear is not serious, the drilled hole is a positive deviation. If the drill is used for a long time, the ligament is worn badly and the drill is worn out too, and the hole drilled is a negative deviation
Q:How do I take out an electric drill bit
This kind of electric drill in your picture makes the end of the drill (zigzag) and the electric drill connect to the direction of the electric drill, then you can take it out
Q:What are the main points of drill grinding?
Grind back from the edge of the blade. When the blade is in contact with the grinding wheel, it should be drawn back from the main cutting edge, that is, contact the grinding wheel from the edge of the drill bit and then slowly grind down the whole flank. Gently contact wheel bit penetration, advanced for less grinding, and observe the uniformity of discharge, timely adjustment of the size of the pressure on the hand, but also pay attention to the drill bit cooling, can not be allowed to wear too much, causing the edge to edge discoloration, annealing. When the blade temperature is high, the drill bit should be cooled in time.
Q:The maximum diameter of the hammer is fixed up? How does an electric drill screw in? How big is the drill bit?
If the opening is often marked with the vertical line, then along a circle hole, knocking out the middle can.
Q:Which is better, a white drill or a black drill?
Black becomes nitrided and can be used to drill aluminum products, i.e., soft materials, after improved propertiesThere are 3 processes for producing drills, black for rolling and worst for rolling. White for clean edges and ground. Because, unlike rolling, no high temperature oxidation, the steel grain structure is not damaged, used to drill a slightly higher hardness workpiece.The yellowish brown drill, called cobalt cobalt drill in the industry, is the unspoken rule of the drill. Cobalt containing drills were originally white, produced by grinding, and when they were atomized at the later stage, they were made of yellow brown (commonly called amber), which is the best in circulation. M35 (Co 5%)
Q:Can an electric drill bit a wall
Electric shock: rotation, and hammer is different single hammer, but the hammering force is its strength. Hammer hit is out of the hole, and the hammer is empty irregular.
