For reaming on the workpiece has been drilling (or hole) after processing the hole, mainly in order to improve the machining precision of the hole, reducing the surface roughness, tool is used for finishing and semi finishing machining of holes, generally small machining allowance. Reamers used for machining cylindrical bores are commonly used. The reamer used for machining tapered hole is taper reamer, which is less used. According to the use situation, there are hand reamer and machine reamer, and the machine reamer can be divided into straight shank reamer and taper shank reamer. The hand is straight handle type.
Most of the reamer structure is composed of the working part and the shank. The main part of the work is cutting and calibration function, the calibration Department diameter has inverted taper. The handle is used for clamping by the fixture, and the straight handle and the taper handle are divided.
According to different purposes can be divided into a variety of reamer and so on reamer is more standard, some of our standard commonly used hand reamer, reamer with straight shank machine, taper shank machine reamer, with Morse taper straight shank reamer etc..
The reamer to use into hand reamer reamer and reaming machine; according to the shape is divided into cylindrical and conical reamer reamer (1:50 taper pin reamers with Morse taper reamer two types standard taper reamer reamer). The groove direction, a straight groove and the spiral groove.
The accuracy of reamer is D4, H7, H8, H9 and other precision grades.
According to the shape of the hinge hole, cylindrical, conical and road shape 3;
Installation clip method, belt handle type and sleeve type two kinds;
According to the shape of the slot, there are two kinds of straight groove and spiral groove
A manual reaming general note: 1. workpiece to clamp.2. reaming process, two handed force to balance the.3. reamer out, can not be reversed, because a reamer rear corner, reamer reversal will make chip stuck between the reamer teeth and the wall of the hole, the hole wall is easy to scratch; at the same time, reamer wear.4. reamer after use to clean up, coated with oil, box to avoid bruising edge.
Two. Pay attention to reaming speed and tool amount when machine hinge
Three. Reasonable cooling lubrication must be adopted in reaming
