Abstract
The invention discloses finishing method in a kind of carbide alloy deep hole drill flute, it comprises the following steps: (1) numerical control program is arranged; (2) choose and slotted wheel and buffing wheel are installed; (3) slot; (4) polishing, polishing model is that the emery wheel of D5 or D10 carries out essence throwing to the groove face of carbide alloy depth drill, and is machined to the accuracy value of needs.The method of polishing in carbide alloy deep hole drill flute of the present invention, the groove inner surface of depth drill can be machined to mirror surface accuracy, greatly reduce the coefficient of friction of chip removal and groove inner surface, improve chip removal ability during boring, prevent chip removal from blocking the cutter that fractures, and then improve working (machining) efficiency, cut down finished cost, simultaneously also for operating personnel provide a safer working environment.
Description
Technical field
The present invention relates to a kind of fluting finishing method, finishing method in the groove particularly relating to a kind of carbide alloy depth drill.
Background technology
Diamond emery wheel is all adopted to carry out grinding-polishing in the drill bit groove of current carbide alloy depth drill, the drill bit groove inside surface roughness that conventional polishing process processes is higher, when using this drill bit to carry out deep hole machining, because boring is darker, the solid capacity produced is more, chip removal and drill bit groove inner surface rub larger, so just be easy to pile up in drill bit groove block, thus cause cutter fracture cause workpiece scrap, this has not only had a strong impact on working (machining) efficiency, improve processing cost, also there is very large potential safety hazard simultaneously.
Summary of the invention
Technical problem to be solved by this invention is that the machining accuracy of finishing method in existing work carbide alloy deep hole drill flute is lower, the drill bit groove inner surface processed is comparatively coarse, and then cause chip removal ability more weak, chip removal accumulation in drill flute and boring easily blocks, and then initiation cutter fractures, workpiece is scrapped, and had the drawback of certain potential safety hazard.
For solving the problems of the technologies described above, technical scheme of the present invention is:
Finishing method in a kind of carbide alloy deep hole drill flute, comprises the following steps:
S1: numerical control program is arranged
The anterior angle of the fluting anterior angle of grooved, cutting angle and polishing grooved, polishing angle are arranged consistent;
S2: choose and install slotted wheel and buffing wheel
Described slotted wheel selects D76 emery wheel, D5 or D10 emery wheel selected by described buffing wheel;
S3: fluting
Start numerical control program, first slot with D76 emery wheel alloy depth drill, and reserve the allowance of 0.3-0.5mm at groove core place;
S4: polishing
Be that the emery wheel of D5 or D10 carries out essence to the groove face of carbide alloy depth drill and throws by model, and be machined to the accuracy value of needs.
Preferably, the rate of feed of described D5 or D10 buffing wheel finishing polish is the 30%-50% adopting D76 emery wheel grooving rate.
Preferably, finishing polish adds man-hour, the buffing wheel enlarged diameter first finishing polish selected, and is reduced by FL flange length simultaneously, is then coated with mark at cutter groove Inner Front End 30-50mm place, carries out first polishing; And then progressively reduce the diameter of buffing wheel and increase progressively increase FL flange length repetition finishing polish.
Adopt technique scheme, the present invention at least comprises following beneficial effect:
The method of polishing in carbide alloy deep hole drill flute of the present invention, first D76 emery wheel is adopted to slot, and reserved 3-5mm allowance for finish, then D10 or D5 emery wheel is adopted to carry out fine finishining polishing, when carrying out fine finishining polishing for several times, progressively reduce the diameter that emery wheel is apt in finishing polish, and then the groove inner surface of depth drill can be machined to mirror surface accuracy, greatly reduce the frictional force of chip removal and groove inner surface, improve chip removal ability during boring, prevent chip removal from blocking the cutter that fractures, and then improve working (machining) efficiency, cut down finished cost, simultaneously also for operating personnel provide a safer working environment.
Accompanying drawing explanation
Fig. 1 be carbide alloy depth drill of the present invention groove in the flow chart of finishing method.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
See Fig. 1, in carbide alloy deep hole drill flute, finishing method comprises the following steps:
S1: numerical control program is arranged
The anterior angle of the fluting anterior angle of grooved, cutting angle and polishing grooved, polishing angle are arranged consistent;
S2: choose and install slotted wheel and buffing wheel
Described slotted wheel selects D76 emery wheel, D5 or D10 emery wheel selected by described buffing wheel;
S3: fluting
Start numerical control program, first slot with D76 emery wheel alloy depth drill, and reserve the allowance of 0.3-0.5mm at groove core place;
S4: polishing
Be that the emery wheel of D5 or D10 carries out essence to the groove face of carbide alloy depth drill and throws by model, and be machined to the accuracy value of needs.
In the present embodiment, the rate of feed of D5 or D10 buffing wheel finishing polish is the 30%-50% adopting D76 emery wheel grooving rate.The speed of finishing polish determines brightness in cutter groove and chip removal ability, the speed of buffing wheel is adjusted to the 30%-50% of slotted wheel speed, fully can ensure that in the groove that processes, fineness reaches mirror surface accuracy, greatly reduce the coefficient of friction of groove inner surface and chip removal, and then improve chip removal ability.
In the present embodiment, finishing polish adds man-hour, the buffing wheel enlarged diameter first finishing polish selected, FL flange length and Z-direction are reduced simultaneously, to prevent the cutting edge damaging drill bit during polishing, be then coated with mark at cutter groove Inner Front End 30-50mm place, and be labeled as with reference to carrying out polishing according to this; If desired, progressively can reduce the diameter of buffing wheel and increase progressively increase FL flange length repetition finishing polish, until carbide alloy deep hole drill flute inner surface is machined to mirror surface accuracy.
The method of polishing in the carbide alloy deep hole drill flute described in the present embodiment, first D76 emery wheel is adopted to slot, and reserved 3-5mm allowance for finish, then D10 or D5 emery wheel is adopted to carry out fine finishining polishing, when carrying out fine finishining polishing for several times, progressively reduce the diameter that emery wheel is apt in finishing polish, and then the groove inner surface of depth drill can be machined to mirror surface accuracy, greatly reduce the frictional force of chip removal and groove inner surface, improve chip removal ability during boring, prevent chip removal from blocking the cutter that fractures, and then improve working (machining) efficiency, cut down finished cost, simultaneously also for operating personnel provide a safer working environment.
Above one embodiment of the present of invention have been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalizations done according to the invention application range change and improve, and all should still belong within patent covering scope of the present invention.
