Parameters of milling reamer:
The main parameters of reamer include diameter, length, number of teeth, precision grade and structure characteristics. The diameter range of the reamer is wide, ranging from 2mm to 30mm, the specific size such as 2, 2.5, 3, 3.5, 4, 4.5, etc., the choice depends on the size and demand of the machining hole. The length of the reamer and the length of the head will also vary according to the specific model and application, for example, in some precision machine tool reamers, the total length may reach 182mm, and the length of the head may vary between 15mm and 56mm.
The precision grade of the reamer usually follows D4, H7, H8, H9 and other standards to ensure the accuracy of the machining process, so that the machined holes can meet the specific size and shape requirements . The reamer is generally composed of a working part and a shank, and the working part includes a guide cone, a cutting part and a calibration part, which are used for cutting and calibrating the size and surface quality of the hole; The shank is used to be held by the clamp, and has a variety of forms such as straight shank and taper shank.
The application scenarios of the reamer include finishing and semi-finishing holes, which are often used for reaming or repairing . It can be operated manually or mounted on a drill machine and is suitable for the processing of small and medium diameter holes, including cylindrical holes, cone holes, through holes and blind holes. The design types of reamer are diverse, including hand reamer, machine reamer, high speed steel reamer, carbide reamer, etc., to meet different processing needs.
