Q: Drill 4.2 holes, tap 5 thread, choose what kind of drill sleeve: Tapping 5 of the thread, drilling 4.2 of the hole, you need to drill sleeve, indicating that the screw hole distance, position tolerances, usually is + 0.1.In general, the tolerance of the drill hole to the choice of F7 is 4.2F7, that is, Phi 4.2 (+0.022 / +0.01).Drill sleeve material, you can choose T8, T10, etc., more than HRC60 quenching.Drill sleeve form can be chosen by oneself (fixed drilling sleeve, quick change drill sleeve, etc.).

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?: Drilling holes can not use drilling sleevesReaming will not use reaming, and when the diameter of the hole is large, the method of boring is often used

Q: Can the drill jig designed in mechanical processing be without drill bush?: You can drill without a drill sleeve, but that is a special and rare case. The drill sleeve is designed to prevent rapid wear and tear, and the clamp is seldom made of hard material, so most of the cases are made of drill sleeves.Don't set the diamond for example:1. folder specific very small, and simple structure, once in the diameter of 20 of the aluminum rod drill holes, I directly with a piece of Cr12 material made drilling mold, simple and fast2., the production of a single or very small number of cases, in order to save costs, then basically do not consider the amount of wear, you can not drill sleeves.

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: How should the drill bit of the 4mm bit be calculated?: Drilling sets play the role of drill guide and support, they should be coordinated with precision oriented, but also can not drill and drill sleeve between too much friction, usually with H7/g6 G7/h6

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: 0∶19.212 9.0451∶20.047 12.0652∶20.020 17.783∶19.922 23.8254∶19.254 31.2675∶19.002 44.3996∶19.180 63.348

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 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?: I analyze your accuracy requirements are not high, no problem. The heating temperature is not too high, oil cooling, then take the gun fire roast, return fire, file inspection for hardness
