The characteristics, uses and types of common reamers

The characteristics of the reamer: the efficiency of the reamer (the fine boring is single-edge cutting, and the reamer is cutting at 4-8 edges, so the efficiency is much higher than that of the boring tool), high precision, and the reamer edge has a margin, so the better roughness;

It is used for reaming the drilled, reamed and bored holes on the workpiece, mainly to improve the machining accuracy of the hole and improve the roughness of the workpiece surface. A variety of tools, the machining allowance is generally very large.

Reamers used to machine cylindrical holes are more commonly used.

The reamer used to machine the tapered hole is the tapered reamer, which is rarely used.

According to the usage, there are hand reamer and machine reamer, and machine reamer can be divided into straight shank reamer and taper shank reamer. The hand used is a straight handle type.

Most of the reamer structure is composed of the working part and the handle. The working part mainly plays the functions of cutting and calibration, and the diameter of the calibration place has a reverse taper. The shank is used to be clamped by the clamp, and there are straight shanks and taper shanks. There are many types of reamers according to different purposes, so there are many standards for reamers. Some of our more commonly used standards are hand reamers, straight shank machine reamers, taper shank machine reamers, straight shank reamers, and straight shank reamers. Cone reamer, etc.

The reamer is divided into hand reamer and machine reamer according to the way of use; according to the shape of the reaming hole, it is divided into cylindrical reamer and cone reamer, (standard cone reamer has 1:50 taper pin reamer and Morse taper reamer There are two types of knives. The direction of the chip flute of the reamer has straight and helical grooves.

The reamer precision has D4, H7, H8, H9 and other precision grades.

According to the shape of the reaming hole, it is divided into three types: cylindrical, conical and doorway;

There are two types of mounting clips: shank type and set type;

According to the shape of the tooth slot, it is divided into two types: straight slot and spiral slot.

Customized reamer: Among customized non-standard tools, reamer is a more common customized tool. According to different products, hole depth, diameter, accuracy, roughness requirements, workpiece material, customized reamer will get better results. Longevity, accuracy, roughness and stability.
