The hole used for reaming (or reaming) on reaming workpiece is mainly to improve the machining accuracy of hole and reduce its surface roughness. It is the tool for finishing and semi finishing of hole, and the machining allowance is very small. 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, reamer can be divided into many kinds, so the standard of reamer is also more, we have some commonly used standards have hand reamer, straight handle machine reamer, taper handle machine reamer, straight handle Morse taper reamer, etc..
The reamer is divided into hand reamer and machine reamer according to the usage; the cylindrical reamer and taper reamer are divided into types according to the shape of reaming hole; (standard taper reamer has two types of taper pin reamer and Morse taper reamer); the direction of chip groove of reamer has straight groove and 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
