Embodiment 4
The present embodiment provides a kind of rational design of drilling tool and selections: the geometry of drilling tool is a pass to deep hole machining
The factor of key, the size of drill flute and the discharge of spacial influence drilling cuttings.Current technology has been able to make Tool Manufacturer according to brill
The characteristic for cutting processing designs the drilling tool for being more advantageous to chip removal, and farthest cutter can be avoided to overheat.Using higher
Alloy steel making cutter, can be improved service life；With new special shape, deep hole machining can be assisted.It is opened on drilling tool
Groove can enable drilling cuttings to flow up, and be easy to be discharged out of hole.As using used in shaft-penetrating type high pressure cooling system
Drill gun, wide type drill flute are more advantageous to drilling cuttings discharge.Alloy knife has the cooling hole through entire cutter hub, can make high-pressure coolant
The bottom in through hole, washes away drilling cuttings out by coolant liquid and takes away heat.In actual production, straight trough drill gun makes with the most use.Rifle
Brill can have one or two circular cooling hole, or an independent kidney-shaped cooling hole, coolant liquid are sprayed from the aperture in flank
Out.Since drill gun cutter head system is manufactured with hard alloy, so cutting speed is much higher than high-speed steel drill, can increase per minute
The amount of feeding.In addition, when using high-pressure coolant, chip can effectively be discharged from processed hole, be not necessarily to regular withdrawing chip removal.
It since the drilling rod of drill gun is elongated, is easily deformed, therefore the necessary installation activity bearing on machine tool guideway, bearing can appointing in drilling rod
Meaning carries out on position.The distance between each supporting point of drilling rod is usually 20~50 times of bit diameter.Before drilling, drill gun
The support that guide sleeve and guide hole must be obtained could start main shaft.
The degree of skewness in hole is one important technical indicator of processing quality.In reality production, the processing request of part is got over
Come higher, the degree of skewness of device to hole proposes higher technical requirements.Especially deeper hole, control deflection seem especially heavy
It wants.The principal element for influencing deep hole axis verticality, is the symmetry of drill edge and the guiding condition of drill bit.Therefore, mention
The symmetry of high cutting edge, and longer guiding is used, it is the major measure for improving deep hole axis verticality.Part to be processed table
The not gentle inclination in face, is also large impact the straightness of deep hole axis, because glancing off in rigid drilling, then drilled can be cured
Deep, deflection is bigger, thus must pay attention to carefully correcting at any time.
Using NC deep hole drilling machine it should be noted that other technologies problem:
(1) because of processing the coolant liquid big using flow when, pressure is high, therefore coolant liquid will be filtered strictly, keep cleaning dry
Only, fixture design will also have good leakproofness.
(2) cutter starts should have good guiding performance when cutting, and guiding is typically all to be close to workpiece, also to examine in guiding
Consider the circuit of coolant liquid and the window of chip removal.
(3) deflection of the assembly precision device to hole of guide sleeve has most important influence, and most sensitive factor, has to
Guarantee the concentricity of guide sleeve and work spindle and drill rod box main shaft.The deflection of deep hole machining mesoporous is linear with processing length
Relationship, if guide sleeve length is 50mm, if guide sleeve axis and work spindle axis deviant are 0.04mm, then process hole
When depth is the hole of 1200mm, deflection may reach 0.8mm or more.
(4) degree of skewness of the uniformity coefficient device to hole of workpiece material influences equally very big, and in drilling progress, drill bit can be towards
The position offset that the material is soft.So the workpiece more demanding to degree of skewness, should make as far as possible material structure refinement uniform, this
When the heat treatment of material is just seemed very important.
(5) degree of skewness of the reasonable selection device to hole of cutting parameter also has a degree of influence.Do not influencing manufacturing schedule
In the case where, excessive feed should not be generally used, to avoid the deflection for causing processing hole.
Reasonable drill bit is designed, shank drilling rod apex point is driven；Guarantee that coolant liquid can timely be sent to apex point, drill bit material
Select good heat conductivity.It secondly is exactly that chip removal is hydraulic by force will greatly being capable of timely scrap fallaway.
The application is added to 100 macro-variables that can power off preservation；The thread for being added to a 20ms changes brill for handling
It is required that.When for needing to bore the continuously workpiece in several days thousands of a holes of processing, once shutdown either accident power-off occurs,
It needs to turn back on, directly operation processing program, so that it may continue to process since the hole that last time processes.For one after the breaking of rod
After dividing hole leakage to bore, the case where mending brill is needed, equally also need to only rewrite starting round number parameter and termination parameters of rows of holes
Benefit brill is carried out to this partial hole.In practical applications, in most cases, user only needs to modify drilling parameter, i.e.,
Drilling processing can be achieved.
The preferable specific embodiment of the above, only the invention, but the protection scope of the invention is not
It is confined to this, anyone skilled in the art is in the technical scope that the invention discloses, according to the present invention
The technical solution of creation and its inventive concept are subject to equivalent substitution or change, should all cover the invention protection scope it
It is interior.
