Q:Reaming Reaming hole diameter smaller, why processing material for ductile iron 500?
You first look at the surface of the processing hole is black and shiny, and if so, the following three cases are more likely:1. the reamer is blunt, or the reamer is too wide.2. reaming allowance is too large.3. reaming too fast.
Q:The reamer H7 and H8 are of high accuracy
H7 high, of course
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: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 hole is 9.97, 0.03 margin, but also with 10H7 reamer to hinge it?
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:Machining center reamer reaming holes, big head, small head, bell shaped, this is what is the reason?
You are using a high speed steel cutter, for hard alloy - increase the rigidity decreases beating!!
Q:CNC lathe reamer, how to hinge out 0.4 of the smoothness?
The knife should be sharp, low speed, and oil reaming. 0.4 is hard to reach
Q:Difference between milling cutter and reamer
The reamer has a certain taper, but the pattern of the reamer is vertical ~ the knife end is relatively flat,The pattern of the milling cutter is spiral, with a sharp blade in the cross section
Q:What are the causes of internal bore runout in lathe reaming?
The tailstock is missing. Look at it
Q:Hole directly to 6mm big 2 wire with 6 reamer, after the hole is still too small, how should I do?
What is your workpiece material? Is it a machine reamer? What are the requirements for the accuracy of the hole?If the material is not special and the requirements are not very high words, proper allowance again big, the margin is too small is reasonable in 10-15 wire, it is not easy to discharge cutting reamer, even if the first few can immediately lead to dull small hole!! Cutting fluid, of course, can have an effect, but that's pretty rare!!
