Abstract

The utility model relates to a diamond reamer used for mechanical processing. The diamond reamer comprises a hilt 1 and a knife back 3, and is characterized in that a diamond blade 4 is welded at the tip of the knife back 3. The diamond reamer is simple in structure, long in service life, high in processing precision, and particularly adoptable to processing workpieces with high requirements upon processing precision.

Description

Diamond reamer

Technical field

The utility model belongs to cutter, the diamond reamer that particularly a kind of machining is used.

Background technology

The employed reamer of China's machining industry all is to adopt carbide-tipped reamer at present, and its weak point is that the service life of reamer is low, and machining accuracy is low.

Summary of the invention

The objective of the invention is to overcome above-mentioned technical deficiency, a kind of long service life, diamond reamer that machining accuracy is high are provided.

The technical scheme that the utility model technical solution problem is adopted is: a kind of diamond reamer, comprise the handle of a knife and the knife back, and be characterized at adamantine blade of the tip of knife back welding.

The beneficial effects of the utility model are: this reamer long service life is longer more than 5 times than ordinary rigid alloy working life of reamer; The machining accuracy height is particularly suitable for fine finishining and uses.

Description of drawings

Specify with embodiment below in conjunction with accompanying drawing.

Fig. 1 is the diamond reamer front view;

Fig. 2 is the left side view of Fig. 1.

Among the figure: the 1-handle of a knife; Cold hole in the 2-; The 3-knife back; The 4-blade; 5-buries bolt; The 6-chip area.

The specific embodiment

Embodiment, with reference to accompanying drawing, a kind of diamond reamer comprises the handle of a knife 1 and the knife back 3, is characterized at adamantine blade 4 of the tip of the knife back 3 welding.Handle of a knife 1 is an one with the knife back 3, and handle of a knife 1 and the knife back 3 centers are provided with interior cold hole 2, helps heat radiation during work; Interior cold hole 2 left end points are sealed with burying bolt 5; Be provided with chip area 6 between the knife back 3 and the blade 4, discharge the bits sheet of processing man-hour for adding.

This cutter structure is simple, long service life, and the machining accuracy height is particularly suitable for the high workpiece of requirement on machining accuracy.
