- 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:What is the geometric angle of the drill bit?
- The commonly used bit, roughly divided into rolling twist drill, full grinding drill, is divided into straight shank drills, taper shank drill and 1/2 drill, double auger, single head, short drill center drill, six angle shank drill, electric hammer drill, impact drill, the material can be divided into 4241# and 4341#. 9341#, M35, M42, 6542#, and alloy etc..
- Q:What kind of drills are commonly used in CNC machining centers?
- The bit is divided into common drilling, shallow hole drilling, deep hole drilling, centering drilling and so on. The ordinary drill needless to say, is used to process common hole, using high-speed steel drill general processing 12 hole drill out may be 10 wire -20 wire, alloy drill generally will be larger, but generally small, of course, is in the machine tool spindle accuracy under good circumstances, if the machine bed the vertical beating is not good, what the bit will appear the phenomenon of large hole.
- Q:What are the brands of homemade twist drills?
- General twist drill rolling and grinding, high quality grinding, I used, there are good brands in the processing of steel parts on the whole: drill, drill Gongquan full amount, mine drill, drill the Far East
- Q:What kind of drill is used on the stainless steel countertop?
- Cabinets, doors, drilling, these two are wood, the use of hollow wood opener.
- Q:The maximum diameter of the hammer is fixed up? Can I open the hole? How does an electric drill screw in? How big is the drill bit?
- Put the drill will bite at the top of the hand claw loosen, the drill bit is put into a plug in the end, and tighten with the special wrench, if the old hammer, was struck with an iron wedge bite claw hammer with teeth to tighten the drill.
- Q:What measures can be taken to prevent the bit from breaking?
- In drilling, the pressure must not be too great for the drilling hole to avoid breaking the bit. Especially in the hole is drilled, the drill tip has been exposed to the bottom surface, the feed speed must be slowed down, feed pressure must be reduced. In addition, if the drill is not fast, do not force to continue to use, so that the most likely to break the drill bit.
- Q:How big expansion screw does the 6mm bit have?
- 6mm drills are generally equipped with 5mm expansion screws (the smallest specification).The relationship between the drill bit and the expansion screw is the drill diameter = the expansion screw diameter +2mm. For example, the expansion screw of 6mm shall be opened with 8mm drill bit.
- Q:8mm iron expansion bolts with few drilling drill mm?
- It's a gross mistake to say 8 mm punching. As with a hammer smashed bolt can not. Strictly speaking, 12 mm bit should be used, but if the expansion bolt is not standard, you need to drill 10 millimeters, then twist the hole, it is best to use caliper to measure the diameter of the bolt and then decide
- Q:Grinding the drill bit, how can grinding, and the method of quick crash is what ah?
- By the back edge grinding behind. This is the slow grinding of the entire flank from the edge of the bit. It is easy to dissipate heat and grind. Based on the stability of the consolidation of one or two of the formula, the drill can be gently contact for a relatively small amount of grinding wheel, grinding, grinding to observe the uniformity of the spark, to adjust the size of the pressure, and bit cooling. When the cooling start again after grinding, to continue to set the formula to the one or two position, it is often in the beginning is not easy to grasp, often can't help to correct change their positions.
