Abstract

The invention provides a burnishing reamer for high precision deep-hole processing. According to the burnishing reamer for the high precision deep-hole processing, the problems that the precision is low, the service life is short, the quality of hole processing cannot meet technical requirements in a traditional deep-hole processing tool are solved. The burnishing reamer for the high precision deep-hole processing comprises a first cylinder, a second cylinder and a third cylinder, wherein the first cylinder, the second cylinder and the third cylinder are coaxial and are connected with each other in sequence and in order. The first cylinder is a head of the reamer with a diameter of d1. The second cylinder is a neck with a diameter of d2, and the diameter of the neck is d2=d1-0.5mm. The third cylinder is a handle with a diameter of d3. Six levorotatory guiding lands distribute on the outer circumference of the reamer head at intervals. A carved camber surface can be formed by the carving on the back portions of the adjacent guiding lands.

Description

technical field [0001] The invention relates to the field of cutting tools for metal cutting, in particular to the field of cutting tools for precision deep hole processing, in particular to a squeeze reamer for high precision deep hole processing. Background technique [0002] Usually, small holes that require high roundness, dimensional accuracy, position and surface finish are mostly processed by drilling, rough expansion, fine expansion, rough reaming, and fine reaming. For deep hole reaming, it is necessary to use Longer and more precise guide sleeve; therefore, conventional deep hole processing requires relatively high accuracy of the tool, while the radial runout of the tool after sharpening of ordinary deep hole fine reamer is difficult to control, which has a great impact on the accuracy of deep hole; and for To ensure the processing accuracy of deep holes, a small cutting allowance is usually reserved for fine reamers, but ordinary fine reamers are not wear-resista...
