- Q:How do you tell which materials are used in the test?
- The drill shall be selected according to the material properties of the material to be machined. For example, stainless steel uses cobalt cobalt drills. Use tungsten cobalt alloy bit when producing high heat when the bit is cutting
- Q:How do the drills grind?
- A formula: "edge on the wheel surface." This is the first step between the bit and the grinding wheel, and it is often the students who have not cut the edges of the blade, so they start sharpening on the grinding wheel. It must be hard to wear. The blade here
- Q:What are the differences between the center drill and the twist drill in its structure and use?
- Center drill: prefabricated, precise positioning for hole processing and central hole machining on end faces of shafts and shafts. Guide the twist drill to reduce the error.
- Q:What is the cause of the drilling mud bit?
- Bit selection factors: hydrophthalmia chip design can not meet the requirements; channel chip angle hindered the smooth out of bottom hole drilling.
- Q:What are the weight specifications of the drill pile when the bridge pile foundation is constructed?
- In terms of size, this depends on the size of the hole you want to play. Generally they are 0.8m, 1M, 1.25m, 1.5m, 1.8m.
- Q:Hammer can play with an electric drill steel, can you
- The disadvantage is that the vibration is large and has a certain degree of damage to the surrounding structures. The steel bars in concrete structures can not be passed smoothly. They can not be too close to the building because of the scope of work.
- Q:What drill holes are used to break the screw?
- The metal, its principle is to discharge at the moment, a sharp change of arc temperature and with pressure, so that the metal material of the point immediately melted, gasification, splashed liquid and explosive, condensed into solid particles is the working fluid. At this time, the metal surface is etched into a pit, so EDM can be easily processed on any metal workpiece, so it is convenient and quick.
- Q:What do you mean by 5 times diameter drill?
- The meaning of 5 times diameter drill:Drill depth is 5 times the diameter of the drill bit.Double diameter refers to how many times the diameter of the meaning, mainly refers to the length of the drill bit and bore ratio, is to measure the function of the drill an important indicator, that is, the larger the diameter, the greater the depth of drilling.
- Q:Drills, drills, heating drills, will they be annealed?
- When drilling cast iron, do not use or use 5% ~ 8% emulsion or kerosene. When drilling steel parts, use 3% ~ 7% emulsion. When deep hole machining or cutting speed is higher, feed amount should be large enough to supply enough cutting fluid to reduce the influence of thermal deformation on workpiece and improve the quality of machining.
- 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.
