Q:How about the speed of the drill bit and the feed of the cutter in the machining center?: 1, if I first drill with D13 bit (S600, F80, Q5), and the rest of all milling cutter hole2, casting and steel parts almost turn, the speed can be faster. After 28 of the hole points, use 28 bit S300, F50, Q3. directly3, 35r6 direct spiral down, layer below 0.5-0.8, S1500, F2000-3000

Q:Bit grinding, hair and technical requirements: There is now a knife grinding machine YN-01A+ drill grinding machine grinding twist drill on the market, SG fast drilling, DG long short blade edge deep hole drilling, in the processing of 3D within the hole, the ordinary twist drill into fast drilling, without positioning, direct drilling, hole position accuracy and the efficiency on the use of ultra fast; DG to the mill, if it is less than 10D or above according to the processing of materials and machine tools and other site by cutting and grinding method when less than 3D above 5D; worn by YN-01A+ zzm-a drill bit to meet the basic situation the essence of drill bit efficiency 2-3 times, the service life of the drill bit can provide 3-5 times; this machine operation is simple and fast, without experience in technology, one minute can grind a bit.

Q:Carbide drills and high speed steel drills, which are suitable for working stainless steel?: Easy sticking knifeBoth austenitic stainless steel and martensitic stainless steel exist in the process of chip toughness, cutting temperature is very high. When the tough chip flows through the rake face, the bonding, welding and other sticking phenomena will occur, which will affect the surface roughness of the machined parts.

Q:For 25 bit is much with the expansion screw: For 25 bit is much with expansion screws, fasteners consultant Yu Wenlong think for 25 bit M20 with expansion screws.

Q:What is the maximum diameter of the drill bit 1500W heavy hammer: The input power is 1500W, the maximum bit diameter is 50mm (2 "), and the maximum hollow drill diameter is 160mm (6-1/4).

Q:How do you drill a bit?: Less grinding, first of all, "do not rub", get the drill, that is, grinding, certainly blind grinding. This is a very important step to lay a solid foundation for grinding the next step only when you put a good position before sharpening. The teacher in the demonstration process, according to the methods and skills of practice summed up in simple formulas form explanation and demonstration, students often listen to understand, to do the normal operation demonstration, step by step action demonstration, slow motion model, so that the students easy to accept. Here the use of four formulas to guide the grinding process. Better effect.

Q:By drilling with a bit, why is the hole drilled straight 2 larger than the diameter of the drill?: The drilling depth - to determine the guiding edge and drilling parameters of the drill: shallow ordinary drill, a set of parameters, if more than 10 long deep hole diameter ratio, cooling the drill bit will choose to guide blade, and soon after the first slow step feed, with 2 sets of parameters, the other through hole, then reduce the parameters in the proposal through;

Q:What's the difference between a drill bit and a drill bit?: There are many differences. For example: different materials; drill design structure (tip, blade, groove, handle, etc.) different; processing methods, processes, etc..Turn left and turn right |

Q:My drill iron chuck is missing. How else can I take the drill bit off?: In any section along the bar, the flutes are located are diametrically opposed to each other's position in the flat tube, flat tube and two common edge edge in the pipe on both sides of the belt plane (F F) 90 degrees extension, wherein the knife rod has a maximum in the rigid plane. The orientation of the second plane (E E) of the center cutting edge is approximately 90 degrees with respect to the main rigid direction (F F) of the blade plane or the bottom of the cutter bar.

Q:Tap is M14-H2, drill with big bit: In practice, the thread material is different, the bottom diameter is different: Iron and steel parts are different, coarse and fine teeth are not the same, the habit of hand tapping and drilling tapping are not the same. Standard pitch M14 thread is 2, so the threaded hole diameter of 12, to select 12.20 pieces of steel, there are two kinds of specifications of fine teeth: a pitch of 1.50 or 1, the corresponding threaded hole diameter is 12.60 and 13.10.
