FAQ

How do you determine the size of the drill sleeve with a drill diameter of 6?. Thank you

The inner diameter of the general drill sleeve can be chosen by H9, but the deformation of the drill sleeve after the quenching has to be considered

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?

Tolerable。 T06 or T08 can, but should not wear very fast quenching, the inner diameter of H8, H9, such as the outer diameter with H8/n7 this can often remove.

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

Can the drill jig designed in mechanical processing be without drill bush?

Yes, the material is different. But after the hole is worn, it is difficult to reuse the drilling template, such as using a drill sleeve to replace the worn one, and the clamp still doesn't affect the concrete.

What kinds of drill sleeves are used? What are they used for?

2 types of fixed drilling sleeves; drilling and drilling sleeves;

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

Drill 4.2 holes, tap 5 thread, choose what kind of drill sleeve

5 of the drill bit where to drill ah, with a drill clip on it!

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
