Q:What causes shrinkage hole after diamond reamer machining?

The sharpness of the reamer decreases and no effective cutting is formed. It results in the formation of friction, extrusion and reaming, and shrinkage is the expression of elastic deformation recovery

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

Workpiece runout error is too large

Q:The sale of these spiral reamer (punch) is illegal? Crime?12 blade spiral reamer, right helix 2-3 degreesFront diameter 5.45 to 5.5 mm, rear diameter 5.40 to 5.5 mm, middle diameter 5.75 mm, line depth 0.1mm or so

I don't see the thing, but there's one principle: it's lethal! For example, if you have this thing, it is sharp... Long, let's see, you know, this thing is used to kill people... OK, suspected of committing a crime, may constitute a crime of illegally controlling a knife.

Q:Processing materials for aluminum parts, unilateral processing allowance of 0.7 mm, four blade is indeed higher machining accuracy, but the row cutting than the three blade almost

Since it is reaming, choose three blades. Black holes make sense.

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:Usage of valve reamers for motorcyclesCG150 CG125 bedroom, 110, reaming of motorcycle valve reamers?And the order after which the reamer is used?

The standard name should be called the floating boring tool are called floating reamer.Limited by tool size. This can be done very little boringGeneral bought the knife head, you want to do a floating boring bar to buy backThe handle is set according to the cutter setting of your machine tool. It can be a straight handle or a Morse taper handleBoring bar to quenchingAfter quenching by cutting a groove installation boring head. Tank size tolerances than boring head 0~0.02mm.The size of the boring boring head need to adjust themselves according to machining hole size.

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: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:To machining M8, blank hole reamer processing thread with what specifications of the machine (bottom)?

A drill with a diameter of 6.7 and a M8 tap (also called a tap). Not reamer. There is in the Baidu library, you enter the "drill thread bottom hole" see,Your 7H in the thread accuracy level is a rough level, there is no need to use reamer, and you find 6.7 of the reamer to find it? The internal thread accuracy is divided into three grades, precision, 4H, medium, 6H, rough, 7H. GB recommended using 6H.

Q:Four what are the advantages of titanium blade reamer

The most direct tool life can be extended
