Abstract

The utility model discloses a lathe cutter, comprising a cutter head fixed on the lathe by a cutter bar and a cutter point formed by a plurality of edges of surfaces, wherein the material of the cutter bar is common structure steel, the material of the cutter point is YH2 bar steel, the negative rake of the cutter is -7degree- -8degree, the back angle is 8-10degree and the cutting edge inclination angle is -6degree- -8degree and the cutter head does not uses a chip breaker to increase the intensity of the cutter head. The lathe cutter has advantages of high efficiency, cleanliness (no need of cooling fluid) and low cost and makes the parts to be processed to obtain the good surface integrality and whole process precision.

Description

A kind of lathe tools

Technical field

The utility model relates to a kind of lathe tools.

Background technology

As everyone knows, grinding equipment such as flat stone mill, peripheral milling, equipment such as projection grinder are limited, and processing cost is quite high, and adopt means of a hard-turning process to process this type component, cutter is a key technology, at present be applicable to that in the world the cutter of hard turning mainly contains the CBN cutter, AL2O3/TiC sintex, PCD cutter, ceramic tool etc., but this class cutter ubiquity cost is very high, and procurement cycle is long, the big and shortcoming that is difficult to obtain promotion and application of sharpening technology difficulty.

The utility model content

The purpose of this utility model is to provide a kind of lathe tools, and it has the working (machining) efficiency height, and production cost is low, wear-resisting, good heat resistance and the good characteristics of versatility.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of lathe tools, it comprises cutter head, described cutter head is fixed on the lathe by knife bar, and described cutter head is provided with the point of a knife that is made of most surperficial seamed edges, wherein, the negative rake of described cutter is between-7 °～-8 °, and relief angle is between 8 °～10 °, and cutting edge inclination is between-6 °～-8 °.

The width of the negative chamfered edge of described cutter determines that according to formula D=0.5f～1.0f D is the chamfered edge width; F is the amount of feeding.

The beneficial effects of the utility model are, described lathe tools cutter head adopts YH2 shaped steel, on cutter head structure, do not adopt chip-breaker to increase the intensity of cutter head, not only has high efficiency, clean (need not cooling fluid), low cost and other advantages, and can be so that institute's processing parts obtains surface of good integrality and whole machining accuracy.

Description of drawings

With embodiment the utility model is described in further detail with reference to the accompanying drawings below.

Fig. 1 is the structural representation of the utility model lathe tools;

Fig. 2 is the main geometric parameters schematic diagram of the utility model lathe tools;

Fig. 3 is the preceding sequential schematic of putting of the blade weldering of the utility model lathe tools.

Among the figure:

The specific embodiment

Please refer to Figure 1 and Figure 2, Fig. 1 is the structural representation of the utility model lathe tools; Fig. 2 is the main geometric parameters schematic diagram of the utility model lathe tools; In present embodiment, a kind of lathe tools, it comprises cutter head 2, described cutter head 2 is fixed on the lathe by knife bar 1, wherein, cutter head 2 materials are YH2 shaped steel, and described knife bar material is a general structural steel, and described cutter head 2 is provided with main cutting face 3 and secondary cutting face 4, described main cutting face 3, the point of a knife 5 of the seamed edge formation of secondary cutting face 4 and front 10, and described cutter adopts than big negative rake, according to the difference of cutting adjusting, negative rake ro is between-7 °～-8 °, in order to reduce friction and the work hardening phenomenon, relief angle ao is between 8 °～10 °, in order to strengthen the intensity of cutter head 2, cutting edge inclination A and does not adopt chip-breaker on the cutter between-6 °～-8 °; The width of negative chamfered edge determines that according to formula D=0.5f～1.0f D is the chamfered edge width; F is the amount of feeding.

Please refer to shown in Figure 3, Fig. 3 is the preceding sequential schematic of putting of the blade weldering of the utility model lathe tools, during welding blade 9, place scolder 7, solvent 8 and YH2 blade 9 successively in the cutter groove 6 on cutter head 2, heat blade 9 behind the heating cutter hub earlier then, make both reach 940 ℃-960 ℃ of best welding temperatures simultaneously, be no more than 5S weld interval, at last insulation in the blade 9 insertion tempering furnaces that weld was got final product in 2 hours.

Above-mentioned lathe tools not only have high efficiency, and clean (need not cooling fluid), low cost and other advantages, and wear-resisting, good heat resistance and versatility are good, can be so that institute's processing parts obtains surface of good integrality and whole machining accuracy.
