The reamer is a general-purpose tool for machining high-precision holes. It guarantees the surface roughness and dimensional accuracy of the machined surface by micro-cutting and squeezing. Reaming on a common machine tool, whether with a front guide or front belt, rear guide Or a reamer without a guide, the reamer should be mounted floating. This is because the process system is difficult to ensure that the center line of the reamer and the center line of the preformed hole of the workpiece are coaxial when reaming. Often, the rigidly connected reamer generates a wobble during rotary cutting, causing the hole to expand in size, the shape error is excessive, and the surface roughness value is increased. Therefore, it is necessary to change the rigid drive to a floating drive, and use a special chuck to hold the reamer. There are many forms of special chucks, which should abide by common requirements and basic principles.
