Q:What are the causes of internal bore runout in lathe reaming?

Workpiece runout error is too large

Q:What a few general tolerances reamer level holes to machining, such as phi 10H7, the high precision hole boring

1. mechanical processing, general IT7 and IT8 reaming can be used as the end of the process.2. the boring can eliminate the machining deviation of the front process to a certain extent.The 3. reamer is a sizing tool, and the final bore diameter is mainly determined by the cutter.4. cutter diameter is adjustable, adjustable aperture is by the skills of staff to ensure the.5. reamer is a multi edge cutter, it has higher machining stability, higher work efficiency, easier to obtain good surface effect of workpiece.6. do not take measures, larger hole boring cutter to shock.7. boring is not suitable for the processing of smaller diameter holes.

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

Require bright words, need to use two cutter, rough fine twisted twist. Slow down. Add oil. And the best use of the spiral reamer.

Q:Why are the dimensions of the reamer larger than the size of the hole?

This is certainly bigger than hole cutting tool, the key is you choose how much allowance, allowance is processed in your material, to see if he had deformation like, generally with a diameter of 0.1 to about 0.15mm, is relatively good. Thank you

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

The reamer used for machining is of good quality and 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. 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 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. The structure of the reamer is mostly composed of the working part and the shank part. The main part of the work is cutting and calibration functions, the calibration Department has inverted taper diameter. The shank is used for clamping by the clamp and has a straight handle and a taper handle.

Q:What is CNC reamer?

Generally refers to the single indexable blade reamer (currently only international companies only), such as Sweden and Germany is MAPAL indexable single edge reamer, cutting smoothly without vibration, high machining accuracy, reaming allowance, high cutting speed, shape and position error is small, long tool life;But some people put the reamer in the NC machine tool called NC reamer, the scope is big, a reamer, common straight shank machine machine reamers with adjustable pressure, expansion reamer, reamer taper and taper shank reamer etc..

Q:Machine is a horizontal machining center Huakai, machining hole size is 14mm through hole, the first with 13.5 bits, then the 14 hinge reamer, reamer is 120 speed 320 feed speed, casting hardness is HB170 ~ 241, made out of the hole often bell shaped, reamer blade also day after day grinding, grinding or not, sometimes for a new reamer like bell. Who can help me analyze the reasons?.

I said you are so talented! Leave 0.5 of the remaining material! More than 13 of the drill bit is taper shank drilling, 0.5 mm a specification. But our experience shows that all the following 4MM are left in excess of 0.1MM. 4MM more than 0.2MM remaining material. To help you develop the process; hit the center drill - with D8 drill THR through; - 13.5 drill reaming - using D8 milling round processing, inverted 13.8THR (through) - with D8 milling round processing, DEP (depth) 8MM as a guide. Dimensions are guaranteed to be around 13.95 with 14 reamer G81 instruction S120F100 plus coolant. Not in place, you cut me. There are reamer, you do not go grinding; kill you do not rub; 14 of the reamer should be welded machine reamers? You see, the front bevel is not a chamfer. It's a cutting edge. It's a guiding role. After grinding, it's almost useless. We can use a reamer for a long time. And did you see the deflection of the reamer on the tester? Machine reamers, yaw, no-load control in 0.02, you can easily guarantee to +0.01 to +0.015. Reamer S320, when used as a milling cutter? The reamer must not be twisted at high speed, while the iron is cut at high speed without enough time to remove it. Cause extrusion deformation; twisted holes are generally large and small. Generally speaking, you don't have any big problems with 1000/D. D is the reamer size
