Abstract
The utility model relates to a boring tool, which comprises a circular hilt, a tool bar connecting positioning step, a tool bar and a blade, wherein the circular hilt is inserted into a machine. The tool bar connecting positioning step is arranged at the lower end of the circular hilt; the tool bar is arranged at the lower end of the tool bar connecting positioning step; the blade is arranged at the lower end of the tool bar; and two curved chip flutes which are symmetrical to each other bilaterally are arranged on an end face of the tool and disposed on the lower portion of the tool bar. By the aid of the curved chip flutes arranged along the end face of the tool and disposed on the lower portion of the tool bar, chips generated during machining can be discharged in time, surface precision of bores machined by the boring tool is increased, and quality of products machined by the boring tool is improved. In addition, the boring tool is simple in design and low in manufacturing cost.
Description
Technical field
The utility model relates to a kind of cutter, refers in particular to a kind of multiple-cutting-edge heavy boring cutter that is used for hole processing, belongs to the metal cutting processing technique field.
Background technology
In machining, carry out hole processing through boring cutter usually.Nowadays the boring bar of boring cutter is generally a round bar on the market; But boring cutter is carrying out in the working angles workpiece; Outside such smear metal meeting row is not portalled, can chip removal in process smooth and " vexed cutter " can not be accomplished processing smoothly; The surface roughness in the hole that chip removal freely also possibly not cause processing has reached not requirement, and influence processes the quality of product.
The utility model content
The utility model purpose is the high boring cutter of product quality that a kind of low cost of manufacture is provided, processes for the deficiency that overcomes prior art.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of boring cutter comprises the round handle, the knife bar that insert lathe and connects positioning step, knife bar and blade; Said knife bar connects the lower end that positioning step is arranged on round handle; Said knife bar is arranged on the lower end that knife bar connects positioning step; The lower end of said knife bar is provided with blade; The bottom of said knife bar has the chip area of arc along the cutter end face.
Preferably, said chip area is symmetrical has two.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The boring cutter of the utility model because the bottom of knife bar, has the chip area of arc along the cutter end face, makes that the smear metal in the process can in time be discharged, and has increased the surface accuracy in the hole of processing, has improved the quality of product processed.The utility model simplicity of design, low cost of manufacture.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the stereogram of the boring cutter of the utility model.
Wherein: 1, justify handle; 2, knife bar connects positioning step; 3, knife bar; 4, blade; 5, chip area.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
The described a kind of boring cutter of the utility model shown in accompanying drawing 1 comprises the round handle 1, the knife bar that insert lathe and connects positioning step 2, knife bar 3 and blade 4; Said knife bar connects the lower end that positioning step 2 is arranged on round handle 1; Said knife bar 3 is arranged on the lower end that knife bar connects positioning step 2; The lower end of said knife bar 3 is provided with blade 4; The bottom of said knife bar 3 has the chip area 5 of arc along the cutter end face; Said chip area 5 is symmetrical to have two.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The boring cutter of the utility model because the bottom of knife bar, has the chip area of arc along the cutter end face, makes that the smear metal in the process can in time be discharged, and has increased the surface accuracy in the hole of processing, has improved the quality of product processed.The utility model simplicity of design, low cost of manufacture.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
