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

The speed is related to the material of the workpiece, the size of the reamer, the allowance for machining and the roughness requirements. General steel with high speed steel cutter cutting speed is 20 meters per minute speed N=1000*v (cutting speed) / PI D, such as the 10 reamer in 20 meters cutting speed speed of N=1000*20/ (3.14*10) = 640 rpm, feed F= feed (MM/) such as *N (speed), reaming feed is 0.2/, then F=0.2*640=128MM/. From the above formula, we can choose the most economical parameter as much as possible under the premise of meeting the quality requirements.

Q:What are the major brands of reamers I?

Domestic CRM, slightly higher accuracy

Q:Difference between milling cutter and reamer

Besides they say, the most intuitive is that the blade part of machine reamer is very short, while the neck is very long, so it looks like a long dumbbell.The end mills have longer cutter teeth, accounting for 1/2~2/3 of the overall length of the tool, and the neck is short. The cutter tooth is spiral and has fewer teeth. It looks sharp.People who don't know much about knives do so.

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: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.

Q:Can the machine reamer be installed on the milling machine?

Look at what milling machine you use and what knife clips, such as my milling machine can be. You can ask the old man and try it yourself

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:If you want to drill out 20 of the hole with a reamer, what size drill should you use first?

Because some of the drilling bit out of the hole is too large, such as drilling 19 of the drill hole is often 19.1/19.2, this situation should be more often encountered. If the reamer you use for machining is of good quality, it is recommended that the drilled hole be 19.9. Usually, the allowance for the reamer is 0.1-0.2mm. As to how large the drill is, it depends on how large the hole you drill out of. You can try using the 19.5 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:In mechanical engineering materials, what are the materials of the reamer?

General hand long edge reamer reamer and material for machine tool steel, machine reamer high speed and large machining allowance for hard alloy, including the use of hard alloy reamer to do some non-standard materials with complex shape machine.
