Q:How do the drills grind?
The drill shaft is slanting out of the front angle.." Here is the relation between the axis of the drill bit and the surface of the wheel. "Frontal angle", that is, the vertex angle of 118 degrees + 2O half, about 60 degrees, this position is very important, directly affect the top of the drillAngle size and main cutting edge shape and cross edge angle. To remind students to remember a commonly used 30 degrees, 60 degrees, 90 degrees triangular plate angle of 60 degrees, students easy to master. A formula and formula two refers to the relative position of the grinding beforeThe two should take overall consideration, and don't neglect to set the oblique angle in order to settle the edge of the blade, or ignore the edge of the blade in order to set the oblique axis. These errors are often present in actual operations. At this point the drill is in the correct position
Q:What kind of steel do you need to drill?!
A cemented carbide drill bit with an average size of 1 microns. This kind of drill not only has high hardness, but also improves the compressive and bending strength. In order to save the cost of many bits by welding handle structure, the original bit for the whole hard alloy drill, the back part of the handle adopts stainless steel, but the cost is greatly reduced due to the use of different materials and its dynamic concentricity is inferior to the whole hard alloy bit, especially in the aspect of small diameter.
Q:What drill does 42CrMo use to drill better?
Carbon structural steel 42CrMo, with ordinary high-speed steel drill bits can be larger, with 60 holes, first with a drill hole, then the reamer drill bottom hole expanding.
Q:Which material, gb1436 and 6542, has a good drill?
6542 refers to the content of various elements in this material. For example, 6542 is W (tungsten) content of about 6%, Mo content of 5%, Cr content of about 4%, V content of about 2%.
Q:Good or good tungsten cobalt steel drill bit.
Cobalt drill good impact resistance. For the machined material hardness, or vibration machining occasions.
Q:How do the new pros or cons drill the drill bit without the key?
This is the hand chuck chuck, is divided into two parts, the front end is used for elastic, rear end is fixed, you want to unload the drill, left to right back to the front to turn in the opposite direction can be loose, Anhui, Bozhou, great electrical firm opened, welcome patronage. Address is: Wanfu market, B building, No. 76-77, which is the general agent of broad brand. Cost-effective
Q:Tap 10 taps, what size drills do we use?
Brief introduction of tap:As a tool for machining internal thread taps, according to the shape can be divided into straight edge and screw tap tap, in accordance with the use of the environment can be divided into hand taps and machine taps, made in accordance with the specifications, and can be divided into metric, British tap, according to the origin can be divided into domestic and imported tap tap. Tap is the most important tool for operators to process thread.
Q:What kind of drill is drilled by 40Cr heat treatment with hardness above 40 degrees?
The products made from these materials are almost indestructible, and they pose new problems: how can they be processed into the final product in the most economical way?. It is gratifying to note that the tool suppliers have made new progress in developing milling and turning the blades of high hardness materials. At present, the coated carbide, metal ceramic, polycrystalline boron nitride (CBN), and polycrystalline diamond (PCD) material blades have been applied. The special shape of these advanced materials, the blade of the surface of the special coating attached to the process, can withstand mechanical impact and wear when the heat generated. However, the use of these blades requires additional external conditions, one of which is the close coordination of experienced tool suppliers.
Q:Construction drills, woodworking drills, high-speed steel drills, shapes and uses, what's the difference?
A construction bit, a carpenter's drill, has the same diameter as a shank and is longer than a bit of a high-speed steel.High speed steel drill stem generally 3.175mm diameter, see need, more than 6.5mm rarely.The drill bits in 3 are of different materials
Q:What drill is best?
The general drill is HSS high-speed steel, and if a good point is high-speed cobalt containing steel, black should be treated by blackening! Black Brown should be TIALN coated!! This drill is usually not custom-made, at most, take the standard drill bit to make a TIALN coating!!
