Q:Electric hammer drill killed what should take down
Electric hammer drill, is the "two function drill" and "hammer" handheld electric tool, "rotary cutting drill", with the impact of the impact mechanism of driving impact drill bit, drill driven in rotation at the same time, there is a direction perpendicular to the rotation of the rotary drill reciprocating hammer exercise. For concrete, brick, tile, marble and other materials drilling. "Hammer" to drive the impact force of drill rod, used for concrete, bricks and other materials on the slotting, holes or broken concrete etc..
Q:What's the difference between full mill and rolling twist drill?
The full grinding twist drill is made of Kunlun twist drill, which is especially high cost, especially durable, and can be used by 1 of them for more than 300 eyes! It is awesome, and playing is stainless steel.
Q:How do we drill a tile with a thickness of 5mm glazed, without a glass bit, only the impact bit? What's up? The brick is attached to the wall!
Slowly switch, carefully slow drilling tiles, and then force, this is a meticulous work, luck plus technology, but first of all to check whether the brick affixed to dense, if not dense, ninety-nine percent to break.
Q:How big are the 7 bits that have worked up?
8mm's expansion tube uses a drill with a diameter of 8mm. If it is 8mm's expansion screw, use a drill with a diameter of 12mm.
Q:The difference between left and right drills used to drill holes
The use of left-hand drill, mostly because the machine tool design can not meet the needs of the right-hand bit, as some spindle can not meet the right-hand thread, you must use the left-hand thread. The specific situation is not practical, it is difficult to say too clear.
Q:What size drills are we going to use to drill the holes in the M7 and with the larger twist drills?
The common thread M7 second series, not commonly used, the coarse thread pitch according to the national standard of 1mm, therefore, the bottom of the thread holes at the 6mm, actually should be: the bottom hole diameter of =7-1.06p, where p is the pitch, calculated 5.94mm, underport with 6mm drill bit, not too bad. After drilling, tap with M7 tap.
Q:Small bit drilling, drilling machine speed is fast or slow?
The two cutting edges should be the same length, and the cutting edge is usually between 8~12 degrees. Do not cut the cutting edge even lower than the back angle, so that the drill can not be drilled. In addition, the drill bit should be slightly sharpened so that the axial resistance of the bit during drilling will be reduced, so that the drill can save a lot of effort when drilling down.
Q:Angle action and characteristics of standard twist drill
Front angle gamma Om (since the front surface of the twist drill is a spiral surface, the front angles of the points on the main cutting edge are different. From the outside, the center angle decreases gradually. The rake angle at the nose point is about 30 degrees, and about -30 degrees near the cross edge. The front angle on the cross edge is -50 degrees to -60 degrees.
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:How about the speed of the drill bit and the feed of the cutter in the machining center?
1:S= (1000 x cutting standard value) / (3.14 * tool diameter)The cutting tool standard value is supplied by the cutter supplierF according to cutting tool standard value. Measurement of feed per turn. I usually give D13 1300 RPM feed 250,2: faster than the above3:R6 knife milling 45# steel can give 800-1200 rpm F to 200-400. According to the depth to addition and subtraction.In fact, according to the formula to calculate, the feasibility is not high, you are not programmed to bring the tool standard every time, or, according to experience, it is better
