When the internal surface of tungsten carbide reamer is rough, it will cause these problems:

1.The hinged blade mouth is not on the same circumference;

2.The tungsten carbide reamer’s cutting part pendulum has poor tolerance, its edge is not sharp and the surface is rough;

3.Due to material relations, it does not apply to pre-zero or negative rake angle angle reamer.

The tungsten carbide reamer will have problem with diameter size in working, the circumstances are the followings:

1.Tungsten carbide reamer hinged blade’s diameter size design value is too large or has the mouth burr;

2.Cutting speed is too high, feed allowance IS inappropriate or excessive;

3.Tungsten carbide reamer main angle is too large;

4.Tungsten carbide blade hinge on chips adhered mouth tumor;

5.when sharpening the blade opening swing hinge poor tolerance;

6.when installing carbide reamer taper shank surface oil is not clean or cone has bump hurt;

7.shaft bending or spindle bearings is too loose or damaged.

When the tungsten carbide reamer’s diameter size has increased or the error is large, there are the following solutions:

1.Being appropriate to reduce the outer diameter of the reamer according to the circumstances ;

2. Having appropriate adjustments to reduce the amount of feed or allowance;

3.Straightening or bending can not be scrapped reamer;  

4.Choosing a better cooling performance cutting fluid;

5.Adjusting or replacing the spindle bearings.

Tungsten carbide cutting tools with one or more hinge cutter for removal of the hole of the machined surface of the thin metal layer rotary cutter. After processing through the hole cutter can obtain precise size and shape.
Tungsten carbide reamer for reaming the hole after processing has been drilling (or reaming) on the workpiece, is to increase the precision of the hole, reducing the surface roughness of the hole is used for finishing and semi-finishing processing tool , allowance is generally small.
Tungsten carbide for machining cylindrical bore reamer more common. For machining a tapered bore is tapered reamer reamer, relatively less. The tungsten carbide reamer is mainly used to process high difficult hardness materials.
Judging by the use with a hand reamer and machine reamers, machine reamers can be divided into straight shank reamers and taper shank reamer. The hand is the straight shank type.
