Q:What's the difference between a bore cutter and a reamer?

In general, a reamer is fixed size tool, cutter is adjustable size tool.

Q:In mechanical engineering materials, what are the materials of the reamer?

Mainly tool steel and hard alloy

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 speed is not fast, generally more than 300400 on it. What is your tolerance?There are scratches generally have to squeeze the squeeze, the margin is large, generally 5 silk on it.

Q:The difference between the reamer and tool?

Each reamer is distributed on the same cylindrical cylinder with many knives and many blades, each reamer has only a fixed aperture processing range, and is used for separating and using.Although there are many boring cutter blade, but only a knife, it can not limit the size range of processing.

Q:The drill holes to make reamer reaming little what method is solved, (drill reaming to hit Phi 8.5, Phi 9)

The bottom is too small. Hinge 0.5 at once, aren't you afraid to damage the reamer? The general rough hinge margin is 0.15~0.35mm, and the precision joint margin is 0.1~0.2mm.

Q:Machining center with 4MM and 6MM white steel reamer, 45 steel material, spindle speed and feed speed settings how much ah!

Reaming speed can not be high, there are generally dozens of turns on it, especially after the material has been quenched and tempered, itself has a certain degree of hardness. When reaming, it is best not to use automatic feed, that is easy to make the hole out of the hole to form regular spiral lines, just like thread. When reaming, add some daily vegetable oil, so that the hole will be very light. The margin of the hole generally has a 0.1~0.2mm on the line, the margin is too large, it is easy to break the reamer, twisted out of the hole is not only light.

Q:What drill and reamer are used to process an empty diameter of 8mmH7?

Drill with a small bit 2.8mm-4.2mm first, and then use 7.8mm to expand the hole. Then machine reamer 8mmH7. Reaming speed should be slow, small and uniform, add oil lubrication cooling. It can be machined into a qualified 8mmH7 hole.A rotary tool with one or more cutter teeth for removing thin metal on the surface of a machined hole; a rotary finishing tool having a straight or spiral blade; used for reaming or trimming.A drill, comprising a cutter rod, a cutter rod tip, tip two is located in a main plane (C - C) on the cutting insert (5, 5 '), the cutting blades (5, 5') have in common second planes (E - E) on orientation the short cutting edge center. The blade forms a point like center, the cutting edge is used to enter the workpiece, and thereby the bit is aligned. Two chip grooves (6, 6 ') are arranged on the cutter bar, and the chip removing slots (6, 6') extend from the tip to the end. In any section along the bar, the flutes are located are diametrically opposed to each other's position in the flat tube, flat tube and two common edge edge in the pipe on both sides of the belt plane (F F) 90 degrees extension, wherein the knife rod has a maximum in the rigid plane. The orientation of the second plane (E E) of the center cutting edge is approximately 90 degrees with respect to the main rigid direction (F F) of the blade plane or the bottom of the cutter bar.

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

This is not a problem of higher accuracy, but a problem of tolerance and fit.

Q:What is the machining accuracy of the reamer?

The fine hinge can reach Ra0.63 Rz3.2

Q:Mr. Cui, Kong is 9.97. I want to use my 10H7 reamer to reaming the hole with my hand. The book said that small or excessive margin will affect the reaming accuracy, then 0.03 of the margin can also be reaming to hinge it? I don't quite understand why the small margin affects the accuracy of reaming If so, what else would be done with thick hinges and precision hinges?.

Each knife distribution margin will be not the same, you are asked to assign allowance Oh, recommended by electroplating diamond reamer, you do not know the accuracy is not high, if the demand is high, is recommended by electroplating reamer, it can be divided into coarse and fine reamer to hinge, to consult Henan stone diamond reamer.
