Q:Would you tell me if there is an approximate range of speed required for machine reamers in reaming?

With my experience:The next thing we can do is to reduce the amount of stay as much as possible.I think the lower the speed, the better the roughness.The slower the feed, the better the roughness.Enough cooling water must be added.

Q:What is the machining accuracy of the reamer?

The fine hinge can reach Ra0.63 Rz3.2

Q:Why reaming with reamer is the workpiece of ductile iron 500, the aperture will be smaller, and the aperture requirement is 9. After reaming, the reamer will not enter the hole. What is the reason why the hole is too small for the reamer to go in?

The precision can not reach. BECK-AUGUST world's top producer of precision cutting tools. BECK has 90 years of production experience and the most advanced production equipment, with its excellent product design and manufacture in the world leading drilling tool production, the non-standard cutting tools with the characteristics of high quality, precision has been widely used in automotive, aerospace and other fields.BECK single blade hinge adhering to the clamping tool not grind all the advantages, when the cutting tool wear or failure, as long as the replacement of the knife, a slight adjustment can be put into production. The fine adjustment mechanism can precisely and flexibly control the diameter of the blade and reverse the cone to meet the processing requirements. The whole process guide bar made of hard alloy, metal ceramic or artificial diamond can effectively control the treatment accuracy. I suggest you try some of your homemade reamers.

Q:The problem of poor chip removal, special reamer scraps can not be found out. What's the main problem?

Reaming is not large, resulting in little chip; most of the reamer is a straight edge, even with a spiral angle reamer is not in order to chip (although there is a certain chip removal effect). It's usually artificial chip removal.

Q:What causes shrinkage hole after diamond reamer machining?

Large deformation of aluminum, increasing width of tool edge!

Q:What is the higher accuracy of phi 25H8 reamer and phi 25H9 reamer?

The 25H8 reamer is more accurate than the 25H9 reamer. The so-called, refers to the hinge hole of high precision H8 H9 high precision hole hole.

Q:When reaming with carbide reamer, there will be a spiral mark on the hole wall. What's the problem?

It depends on what material you are working on.

Q:Diameter 4.2, depth 12, roughness 0.8, tolerance 0.02., cutting, each edge 0.02. material is stainless steel. Carbide reamers are used, with a 45 degree reamer at the beginning and a crack at the tip! Then change to 30 degrees, the middle of the place or collapse! Either the size is too bad! In the gloom!

We use Okazaki with HSSCO8 reamer. The workpiece material is sus304. Moderate speed. Chlorinated wax cutting fluid.

Q:Hit a circle, beating is 2-3 wire, reaming 16 holes should be little problem. 20-30 spare margins are left, and the reamer is new. But why does this problem arise? Ask the teacher for help!!!

Your situation is generally high speed (this time our customers use our reamer also met), then you have allowance is big, then the machining center normal left margin on the line 0.15MM. Finally, this knife is also a bit of a problem, otherwise it won't be a new knife and there will be such a problem. Also ask, you this workpiece material is stainless steel?

Q:How can the reaming of stainless steel extend the life of the reamer and allow Kong Guangliang to help with various problems?

Must work card reamer, oil tapping oil, black thick oil
