Q:What are the causes of internal bore runout in lathe reaming?
The tailstock is missing. Look at it
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:In the lathe, with a floating reamer machining material for cast iron, diameter of 55mm hole, leaving margin 0.1mm, lathe speed is appropriate!!
Reaming is actually the lower the speed, the better, but to balance with efficiency. So, according to the actual choice of 30-120
Q:When reaming with carbide reamer, there will be a spiral mark on the hole wall. What's the problem?
How many spirals do you have?Also, send out your parameters and the current process!!There are many factors that affect spiral lines!!
Q:Would you like to make a straight hole reamer with an outer diameter of 32, an inner hole of 12, and a tolerance of -0--0.02. The inner hole and reamer must be concentric. How can I do that?
Wire cutting, but the processing fee may be more expensive.
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:Use and do not use the threaded hole reamer reamer, what do you mean, how to choose the aperture
Use and do not use the threaded hole reamer reamer, refers to the different machining method of taper thread hole at. Machining taper thread hole, if you do not use the reamer, only in accordance with the minimum size of the taper thread bottom hole drill hole, then taper tap directly using reamer tapping; machining taper threaded hole machining taper thread hole, or the first in accordance with the small size of taper threaded hole drilled outlet, and then use the taper reamer with taper to wring then, the taper taps, so machining taper thread holes, cutting the amount of tap is smaller than the cutting amount without taper reamer reaming tapping more tapping is also easier.
Q:Reaming problem of integral carbide reamer for NC Machining Center
For you the double-edged cutter, S and F on the line four pin gear extrusion
Q:What about cutting edge of reamer?
We use Okazaki with HSSCO8 reamer. The workpiece material is sus304. Moderate speed. Chlorinated wax cutting fluid.
Q:Hole directly to 6mm big 2 wire with 6 reamer, after the hole is still too small, how should I do?
I do not know if you use the cooling fluid, and oil cooling, easy to cause shrinkage hole, cutting fluid cooling hole is normal, if the hole is 5.97, you can hinge again
