The tool has one or more hinge cutter, a rotary tool for removal of the machined bore surface of thin metal, and after the hole cutter can be obtained after processing the exact size and shape.

Reamer for reaming the hole after processing has been drilling (or reaming) a workpiece, primarily to improve the machining accuracy of the hole, and to improve its surface roughness, the finishing and semi-finishing tool for hole , allowance is generally small.

Reamer for machining cylindrical bore reamer more common. For machining a tapered bore is tapered reamer reamer, less used. Judging by the use of there hand reamer and machine reamers, machine reamers can be divided into straight shank reamer and taper shank reamer. Hand do with a straight shank type.

Reamer structure consists of mostly working part and the shank. Working part from cutting and calibration, the calibration of the inverted taper diameter. The shank is used to being gripped with straight shank and taper shank points.

1. Press the different uses can be divided into many types of reamers, reamer on the criteria and therefore will be more, some of our more commonly used standards GB / T1131 hand reamer, GB / T1132 straight shank machine reamers, GB / T1139 straight shank Morse taper reamers, and so on.

2. Press the usage reamer into hand reamer and machine reamer; by reaming shape into cylindrical and tapered reamer reamer (standard taper reamer reamer has taper 1:50 and Morse Two types of taper reamer). Hinge chip flutes direction knife, straight grooves and spiral grooves. The material used for high-speed steel carbide inserts.

Hand reamers are generally made of alloy tool steel (9SiCr), machine reamers material for high-speed steel (HSS), machine reamer into straight shank machine reamers and taper shank machine reamers

Reamer precision D4, H7, H8, H9 and other precision.

3. Press the shape of the reaming sub cylindrical, conical and stepped three kinds;

4. The method of sub-petiole mounting clip type two suits;

5. Press the shape of the alveolar slotted two straight and spiral grooves;

A hand reaming General Considerations

1. To clamp the workpiece being;

2. reaming process, forced to balance his hands;

3. Reamer quit, can not be reversed, because the reamer has posterior horn, reversing reamer cutter makes chips tucked in between the back teeth reamer and the hole wall, the hole wall scratches. Meanwhile, the reamer is easy to wear;

4. reamer used up, to wiping clean, coated with oil, boxing avoid bumps edge.

Second, pay attention to the speed and pass reaming amount of hinges (check metal cutting manual)

Third, reaming must adopt reasonable coolant

Hand guide cone taper smaller rake angle, relief angle smaller than the sharp edge, the edge with the generally narrow, or simply not at the guide cone.
