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

Q: CNC lathe reamer, how to hinge out 0.4 of the smoothness?: Coarse hinge and precision hinge,The reamer must be correct,When reaming, lower the allowance, add kerosene or vegetable oil.If my answer is helpful to you, please accept it as the best answer in time. Thank you!

Q: Can we use milling cutters instead of reamer to process holes, the accuracy of holes H7: With the milling cutter hole processing, smoothness, wear resistance and hole verticality without reamer processing is good, so if only a small amount of processing holes, or the requirements of the hole is not very high, then use the milling cutter will also go.

Q: With a machining center, the diameter of the hole is 28, and the cutting amount of the reamer when reaming: Such a big hole, why not boring.

Q: What drill and reamer are used to process an empty diameter of 8mmH7?: You can refer to the relevant mechanical processing manual, should have an introduction, I think it should be 7.8 of the drill, 8 of the reamer

Q: The edge of the reamer and drill bit can cut metal, one is only oriented, and why?: Reduce the cutting heat caused by friction during processing, prevent the bit and reamer from overheating and change the tool material, affecting the service life of the reamer and drill bit.

Q: Hole diameter requirements 30, 0-4 wire, what specifications of the reamer?: This is to use the corresponding D30 (H7) reamer, of course, D30 (H8) can also choose. These will take longer.

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 is the machining accuracy of the reamer?: Generally can reach H8, Ra3.2. You can also reach H7, Ra1.6, and a little bit of effort".

Q: What's the result of the reaming of the inside hole of the reamer?: You are using manual reaming Reaming, or drilling reaming? General artificial hand reaming, as long as the hands evenly twisted out of holes is not elliptic, if two handed force is not uniform, then wring out the hole could be elliptical; if you are using drilling reaming, drilling machine main shaft the hole is not concentric with the workpiece, the reamer reaming when leans to one side with Jin twisted down hole was wrung may be ellipse.
