- 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?
- 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: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: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: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.
