Abstract
The utility model relates to a kind of brill endoporus cutter, and comprise the cutter hub of handle of a knife and carrying blade, described cutter hub is axially interval with thick drill and smart drill; Described thick drill has chip-breaker; When described cutter at high speeds rotates, described smart drill rotates external diameter and is greater than thick drill external diameter.The utility model scheme is constantly down moved in the process of boring at cutter, first be that thick drill is slightly bored, then smart drill carries out essence brill, shaping to boring time processing, avoid secondary operations and decrease the wearing and tearing of cutter, improve cutting-tool's used life, and then also improve endoporus crudy and efficiency.
Description
Technical field
The utility model relates to a kind of process tool, refers in particular to a kind of brill endoporus cutter.
Background technology
In the drilling process of high-temp and high-strength steel, high-temp and high-strength steel viscosity is large, and toughness is high, and in working angles, easily produce sticky cutter phenomenon, make chip not frangibility, method the most frequently used at present uses chip-breaker chip breaking.Chip-breaker chip breaking utilizes the work hardening of material and is hit, is squeezed and reaches the principle of breakdown strength.In boring procedure, when chip is flowed out from cutter rake face, there is strong friction in the bottom land of chip bottom and chip-breaker, a large amount of heats can be produced, chip heat is constantly delivered to blade from chip, cause blade to produce accelerated wear test or breakage, reduce workpiece surface quality, serious restriction working (machining) efficiency improves.
Utility model content
The utility model object provides a kind of minimizing blade abrasion to overcome the deficiencies in the prior art, improves the brill endoporus cutter of workpiece surface quality.
For achieving the above object, the technical solution adopted in the utility model is: a kind of brill endoporus cutter, and comprise the cutter hub of handle of a knife and carrying blade, described cutter hub is axially interval with thick drill and smart drill; Described thick drill has chip-breaker; When described cutter at high speeds rotates, described smart drill rotates external diameter and is greater than thick drill external diameter.
Improve further as the utility model, described cutter hub and handle of a knife joint face are provided with quenching pad.
Improve further as the utility model, the curved shape of described chip-breaker.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The one of the utility model scheme bores endoporus cutter, constantly down move in the process of boring at cutter, first be that thick drill is slightly bored, then smart drill carries out essence brill, shaping to boring time processing, avoid secondary operations and decrease the wearing and tearing of cutter, improve cutting-tool's used life, and then also improve endoporus crudy and efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is a kind of structural representation boring endoporus cutter of the present utility model;
Wherein: 1, handle of a knife; 2, cutter hub; 3, thick drill; 4, smart drill; 5, chip-breaker; 6, quench pad.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1, for one described in the utility model bores endoporus cutter, comprise the cutter hub 2 of handle of a knife 1 and carrying blade, described cutter hub 2 is axially interval with thick drill 3 and smart drill 4; Described thick drill 3 has chip-breaker 5; The curved shape of chip-breaker 5, flows out with convenient chip breaking, prevents adhesion; When cutter at high speeds rotates, described smart drill 4 rotates external diameter and is greater than thick drill 3 external diameter.
Described cutter hub 2 is provided with handle of a knife 1 joint face the pad 6 that quenches, and this quenching pad 6 bears certain axial force in tool sharpening process, to prevent elaboration power from causing cutter hub to shake distortion, eliminates endoporus ripple and chatter mark.
The brill endoporus cutter of the utility model scheme, constantly down move in the process of boring at cutter, first be that thick drill 3 is slightly bored, then smart drill 4 carries out essence brill, shaping to boring time processing, avoid secondary operations and decrease the wearing and tearing of cutter, improve cutting-tool's used life, and then also improve endoporus crudy and efficiency.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
Claims (3)
1. bore an endoporus cutter, comprise the cutter hub of handle of a knife and carrying blade, it is characterized in that: described cutter hub is axially interval with thick drill and smart drill; Described thick drill has chip-breaker; When described cutter at high speeds rotates, described smart drill rotates external diameter and is greater than thick drill external diameter.
2. one according to claim 1 bores endoporus cutter, it is characterized in that: described cutter hub and handle of a knife joint face are provided with quenching pad.
3. one according to claim 1 and 2 bores endoporus cutter, it is characterized in that: the curved shape of described chip-breaker.
