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: 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 element (drill sleeve), why does your company not use drill sleeve in actual production?There may be several reasonsThe 1 bit and the products to be machined are fixed, and the drill bit has sufficient positioning for steel2 the shape tolerance of the hole to be drilled has no requirementThe 3 bit has a self - located cutting edgeReaming generally does not require additional positioning, the pre drilling itself plays a guiding role. In particular, there are positioning

Q: Can the drill jig designed in mechanical processing be without drill bush?: May not。 The drill sleeve is the guide of the drill bit, reamer and reamer. The tool is of high hardness. If it is not drilled, it will lose its guiding effect very quickly. Drill sleeve materials such as T8A, T10A, is the high quality carbon steel, general file, ordinary drill, scraper, are made of it, high hardness after quenching, can reach HRC60.

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?: The drill bit for the 4mm is generally larger than the drill sleeve about 4 or 0.03Such coordination is more accurateSpecific access to relevant GB requirements

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: What kinds of drill sleeves are used? What are they used for?: 2 types of fixed drilling sleeves; drilling and drilling sleeves;

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
