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?: 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?: 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?: 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: 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?: Drill sleeve can be divided into four kinds, namely: fixed drilling sleeve, interchangeable drill sleeve, fast change drill sleeve, special drill sleeve.Fixed drill sleeve: drill sleeve is directly pressed on the drilling template. The fixing drill sleeve is simple in structure and high in drilling accuracy, but it can not be replaced after wearing. Fixed drill sleeves are suitable for small batch production in a single drilling process.Replaceable drill sleeve: drill is sheathed in the Bush, bushing is pressed on the drilling template, and the drill sleeve is pressed by screw to prevent the drill bush from rotating or withdrawing. When the drill sleeve is worn, loosen the screws and replace them quickly. A single drilling procedure suitable for mass production.Quick change drill sleeve: its structure is similar to interchangeable drill sleeve. When the workpiece in one process has the same hole to be processed by various methods (such as drilling, reaming, reaming, tapping, etc.), the drill sleeve with different apertures can be quickly replaced. When replacing, the drill sleeve gap is turned to the screw and can be taken out.Special drill sleeve: when the structure of the workpiece is not suitable for the use of standard drill sleeve, it can design a special drill sleeve adapted to the workpiece. The height of the drill sleeve is increased by H, the guiding performance is good, the tool rigidity is improved, and the machining accuracy is high, but the abrasion of the drill sleeve and the cutter is intensified, and the H= (1 to 2.5) d is generally taken. The chip space H increases and the chip removal is convenient, but the tool rigidity and the machining accuracy of the hole will be reduced. Cast iron for drilling easier to remove chips, h= (0.3 ~ 0.7) d; drilling difficult to chip out of the steel parts, h= (0.7 ~ 1.5) d.

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
