Q:Specific depends on what number you are cone sets, you can compare:0 1:19.212 9.0451 1:20.047 12.0652 1:20.020 17.783 1:19.922 23.8254 1:19.254 31.2675 1:19.002 44.3996 1:19.180 63.348
Not enough detail ah, a few cones are not aware of their comparison, followed by cone sleeve diameter0 1:19.212 9.0451 1:20.047 12.0652 1:20.020 17.783 1:19.922 23.8254 1:19.254 31.2675 1:19.002 44.3996 1:19.180 63.348
Q:How do you determine the size of the drill sleeve with a drill diameter of 6?. Thank you
The bore size of drill sleeve is determined according to F7 tolerance. That is: 6F7,6 deviation: +0.022. deviation +0.010.
Q:I wonder if it works Because of the large number of drilled holes, the wear of common steel is relatively large. But T10 steel needs quenching. I don't have any specialized equipment here. Usually it is heated by oxygen acetylene, and then it is quenched by oil. I wonder if T10 steel is good. What about the deformation? Outside diameter 15mm, inner hole 8.6MMIf not, what is the best way to do it? Or what to replace?
As the drill material set is the first choice of bearing steel GCr15, the quenching temperature is 835 ~ {850 cooling medium: oil, the tempering temperature is 150 ~ 170 hardness can reach 61 ~ 65}, GCr15 bearing steel with good hardenability, high abrasion resistance, high fatigue life. In general industry, this material is commonly used as drill sleeves. Carbon tool steel T10 drill can also set {the quenching temperature is 780 cooling medium: water or oil, the tempering temperature is 200 ~ 250 hardness of 60 ~ 64} in the use of performance is far better than GCr15 bearing steel. If there is no professional heat treatment equipment should pay attention to the quenching temperature and tempering temperature, especially the quenching temperature is 835 ~ 850 and I hope to help you.
Q:What kinds of drill sleeves are used? What are they used for?
Drill sleeve is divided into fixed drilling sleeve and fast change drill sleeve two kinds. A fixed drill sleeve is used for drilling only. Quick drill bushing, is generally the first to remove the drill sleeve on the drilling, reaming and reaming.
Q:I have seen many drilling techniques in practice, and I find that drilling jigs do not have guiding elements (i.e. drill sleeves). Why do not they use drill sleeves in actual production? And I have seen in many books drilling jig, need drill sleeve of the statement, how is this matter?Reaming in our company is also done by drilling machines. Change the drill bit to the reamer. Do you want reaming?I asked the master of the workshop why the drilling fixture does not need to drill, they do not even know what the drill sleeve is, as if they are in the design of drilling machine clamp, there is no drill sleeve concept.I really don't understand why the drilling jig is using drill sleeves If it is for the tool, you can put on a processed product, and then the tool is ok. Why?
In the actual drilling process, the drilling machine fixture should have guiding elements (drill sleeve).The role of drill sleeve is mainly used to determine the location of the drill bit, reamer, reamer and other fixed size tools, and the structure and size of the drill bush have been standardized. According to the characteristics of the use, the drilling sleeve has four types of fixed drilling sleeve, replaceable drill sleeve, fast change drill sleeve and special drilling sleeve. Moreover, the drill sleeve is inserted into the drilling template by "interference fit".The significance of drill sleeves is that they can locate and guide the machining of the cutting tools so as to improve the machining accuracy.
Q:Drill 4.2 holes, tap 5 thread, choose what kind of drill sleeve
Look at your drill sleeve material is what, if it is rotating drill sleeve, the direct selection of about 0.02 larger than the drill can, if they do need a kind of drilling quenching, will put a bit into the hole position accuracy -- mainly depends on your workpiece hole
Q:How should the drill bit of the 4mm bit be calculated?
Mm to 4 mm, the drill is a straight shank, and the drill chuck is equipped with it. Drills that can be fitted with drill sleeves are all taper shank unless nonstandard.As for the drill sleeve is divided into 0# to 6 # Morse MorseAh ~ problem layman, too lazy to answer
Q:Can the drill jig designed in mechanical processing be without drill bush?
Less quantity can be without drill sleeveThe drill sleeve is used for drilling, hardening and tempering, and the hardness is improved
Equipped with excellent equipment, strong technique force and completed test facilities, the company is a first-level supply member of Chinese Petroleum and Natural Gas Consortium, as well as the member of China Petrochemical Material Resources Market. We have obtained the Production License issued by the nation.we believe that our company will usher in a new takeoff in the near future.
