- Q: What steel blade drill bit, hardness above 60
- It is recommended to use steel bit, two hundred to three hundred RPM (8mm below the hole, more than 8mm, and then reduce speed), pay attention to cooling, the amount of feed should not be too large. For reference only, I hope it will help you.
- 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 the difference between steel and high-speed steel?
- In alloy steel series can't seem to find what it is, "tungsten steel" are a class of materials called hard alloy tungsten steel, this is a commonly known.
- Q: M6 threads need to drill much bottom?
- M6 need to drill 4.8mm hole thread. Calculation method:Generally, the diameter of the Gong bolt multiplied by 0.86 is the diameter of the hole to be drilled.M6 thread refers to the nominal diameter of 6mm coarse teeth, ordinary thread.
- Q: Do you have any special drill for aluminum alloy?
- Aluminum alloy, copper, stainless steel, the hardness of these materials are not high, aluminum alloy, copper soft, frequent drilling process, easy to cut, and there will be a lot of burr. The best choice for some Aluminum Alloy drill bits for different materials when drilling drill main cutting edge angle will be different, the best selection of aluminum cutting angle of 120-135 degrees, the feed is not too high, due to the low, if the best friend can understand the material selection of M42, M35 or 6542, not bad bit a few drill does not move. The bit is divided into a rolling bit and a full grinding drill, and the whole grinding drill is 30% more expensive than the rolling mill, but the effect is much better than that of the rolling mill.
- Q: Deep hole refers to the diameter of drill bits more than times, called deep hole
- DF deep hole drilling: this kind of drill absorbs the advantages of BTA deep hole drilling and jet drilling, and uses single pipe, chip removal, pushing and suction to improve the chip removal ability, and can drill holes at the depth of 8 millimeters or more. Gun drills are usually made of high speed steel or hard alloy. Various kinds of inner chip removing deep hole drilling can be welded or mechanically clamped and indexable carbide inserts according to size. The guide block on the deep hole drill has the function of guiding and centering to reduce the deflection of the drill hole and the vibration during cutting. The arrangement of cutter teeth and guide blocks in deep hole drilling mainly considers the balance of radial forces during chip separation and cutting. The cutter body and the drill rod can be welded or square threaded.
- Q: How big is the screw hole at the back of the torch chuck? Is it a rebound?
- Screw head, some cross flower, six angle, etc.. Generally, the thread is covered with a lock gum.If you want to remove it, it should turn clockwise.
- Q: How can the 1 millimeter drill be worn?
- The "cutting edge" here is the main cutting edge, and students often turn the top and bottom of the mill into "up and down" when they are grinding. The workers who have been working for more than ten years have been working for more than ten years." This action is also important in the sharpening of the drill, and confidence determines power. When drilling. To master the methods, repeatedly "less grinding" test drilling and the appropriate grinding on the horizontal edge, chip is normal, this is very important, must let students stand in automatic hand grinder, is reading books on the knowledge, otherwise it will make the blade blunt, more understanding. The common standard twist drills only have two main flank surfaces, a grinding edge, a transverse edge, an oblique angle, and two main cutting lengths. In a stable consolidation formula, grinding twist drill is also a lot of bad. Students will find that sharpening a certified standard twist drill is not difficult and much more analytical. To remind students to remember a commonly used piece of 30 degrees." This is the slow grinding of the entire flank from the edge of the bit. A formula and formula two refers to the relative position of the grinding before, to adjust the size of the pressure. You can use a large angle bit and another small angle drill students in the test bench drill drill, the drill bit in drilling process of quick cutting, students can quickly grasp the right edge of the twist drill grinding method, 60 degree students, easy to master. It is easy to dissipate heat and grind. After mastering the methods and techniques, but after sharpening, you must ensure the vertex angle
- Q: Twist drill 200mm deep bore, what does the drill grind?
- The drill bits can also be opened with a plurality of chipping grooves to narrow the iron filings. Methods and techniques for sharpening the standard twist drills are described
- Q: When tapping M4, M5, M6, M8 and M10, how big bits of drill (ordinary steel) are used?
- Stainless steel, titanium alloy, steel and other materials hard to be machined: D=d1-0.95P. Still in the case of M10x1.5, hole size D=10-0.95 * 1.5=8.575. (recommendation 8.6)
