Reamer tool product features and uses
summarize
An hinged tool is a rotary tool used for the finishing and semi-finishing of holes, which is mainly used to cut the thin layer of metal on the surface of the machined holes to obtain accurate aperture and geometry and low surface roughness. Reaming is usually carried out after drilling, reaming or boring, and the range of machining apertures is shown in the table below.
Product characteristics
The reamer has one or more tool teeth and can be divided into single-edge reamer and multi-edge reamer according to different processing requirements. Single-edge reamer is suitable for machining smaller holes and higher precision requirements, while multi-edge reamer is suitable for machining holes in mass production.
use
The reamer is mainly used to process cylindrical holes, but it can also be used to process conical holes. According to the use, it can be divided into hand reamer and machine reamer, of which hand reamer is usually straight shank type, and machine reamer is mostly cone shank type.
Structure and parameter
The structure of the reamer is mainly composed of the working part and the handle, the working part includes the cutting part and the calibration part, the cutting part is conical, responsible for the main cutting work; The calibration section is used to calibrate the aperture, finish the hole wall and guide. The shank of the reamer is used for clamping and transmitting torque, the hand reamer is generally straight shank, and the machine reamer is mostly taper shank.
Materials and materials
Reamer materials are usually high speed steel (HSS) or cemented carbide, some reamer will also use coating technology to improve wear resistance and cutting efficiency.
Cutting parameter
The cutting parameters of reamer include cutting speed, feed rate and cutting depth, etc. These parameters have a direct influence on the reamer effect.
Inspection and maintenance
The reamer needs to be strictly inspected before and after use to ensure its accuracy and performance. In the process of use, it is also necessary to pay attention to reasonable cooling and lubrication, as well as the maintenance and maintenance of the reamer to extend its service life.
To sum up, the reamer tool is an indispensable tool in the field of machining, and its precise processing ability and high cutting efficiency make it play an important role in hole processing. By selecting different types of reamer and setting appropriate cutting parameters, the machining quality and production efficiency can be effectively improved. At the same time, the correct maintenance and inspection is also the key to ensure the long-term stable work of the reamer.
