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

With my experience:The next thing we can do is to reduce the amount of stay as much as possible.I think the lower the speed, the better the roughness.The slower the feed, the better the roughness.Enough cooling water must be added.

Q:What are the major brands of reamers I?

Auguste of Germany. Beck (under the German MAPAL group);Dihat (Swiss membership KOMET);Swiss tungsten horse;American APT;Cobalt cobalt germany;German Ruibiege;Spain JMC;American SGS;Okazaki;

Q:The problem of poor chip removal, special reamer scraps can not be found out. What's the main problem?

Reaming is not large, resulting in little chip; most of the reamer is a straight edge, even with a spiral angle reamer is not in order to chip (although there is a certain chip removal effect). It's usually artificial chip removal.

Q:I want to lay 17 hole diameter, valve hole of steering pump, recently the old material is out of order, gray cast iron, which has two cross the oil window, leaving 30 wire end hinge margin, to reach 17 by 5 wire with diamond reamer reaming finally reached 17+0.008mm, but sometimes twisted lax that is the total crude hinge traces, do not know why. Master, tell me why? How to choose the cutting amount, how high the speed, what choice to do cutting fluid? The speed of feed and retract? We use emulsion, right? Thank you

The reaming should not be done with vegetable oil or animal oil, oil or cutting fluid. With the drill hole cutter can not play automatically, because it will form a knife regularly, just like the same thread. Your thick left margin, 30 wire a little big, usually a maximum hinge 20 silk on quite a lot. Reaming general speed to low, dozens of turn, up to 100. High speed, large vibration, affecting smoothness. Take the knife a little faster than the knife at the hole. It is better to use manual feed, steady and uniform feed. Add more oil, usually with soybean oil or vegetable oil, buy those vegetables oil, you can, cheap or good. Feeding and retracting are not reversed, the last time after reaming machine can be stopped, and then brought this to the hole reamer, finish with minimal impact.

Q:Diameter 4.2, depth 12, roughness 0.8, tolerance 0.02., cutting, each edge 0.02. material is stainless steel. Carbide reamers are used, with a 45 degree reamer at the beginning and a crack at the tip! Then change to 30 degrees, the middle of the place or collapse! Either the size is too bad! In the gloom!

Oh, I didn't make it clear. The total margin is 0.1. The speed is 300R/min. Feed 40mm/min. Do you mean spiral reamer?

Q:NC machining, the speed and feed of the reamer

CNC reamer is generally high-speed steel cutting tools, the line speed is generally around 10-20, according to the diameter of your reamer, you can switch on the basis of cutting speed formula. The feed is generally fed to each turn 0.1mm

Q:How do you choose the tolerance of reaming when reaming?

Suggest you see. The worker's Manual of cutting! The cutter head is on.

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:Hole diameter requirements 30, 0-4 wire, what specifications of the reamer?

Hello. It's fine to use a high precision reamer. 980312522QQ Germany BECK shell reamer can meet this requirement. Our reamer is the size after reaming.

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

Two kinds of tools are expanding use, the cutter head is multi edge twist, on the big hole diameter expanding much, bore in the bottom aperture knife can be changed based on flexible, convenient adjustment, cost savings!
