Use different lathe tools or other cutters at lathe, can process various rotary surfaces, as inside and outside circle cylinder, the inside and outside circle conical surface, screw thread, groove, end face and forming face etc., machining accuracy can reach IT8-IT7, surface roughness Ra value is 1.6～0.8, turning is commonly used to process the part of single axis, as d-axis and dish, cover parts etc.If change the installation site of workpiece or lathe suitably reequiped, can also process part (as bent axle, eccentric wheel etc.) or the disc cam of multi-axial cord.In jobbing work, the class part multiselects such as various axles, dish, cover are processed with horizontal lathe or the numerically controlled lathe of wide adaptability; Large and the heavy parts of length short (draw ratio 0.3～0.8) of diameter, multiplex vertical lathe processing.Produce profile by batch more complicated, while thering is medium and small profile shaft, the cover parts of endoporus and screw thread, should select capstan lathe to process.The miniature parts that large quantities of, a large amount of production shapes are not too complicated, during as screw, nut, pipe joint, shaft sleeve etc., multiselect is processed with automatic lathe with semi-automatic.Its productivity ratio is very high but precision is lower.
Endoporus is processed as multiple cut, and different bites join in endoporus many places, and after tool wear, size is different with the error that angle produces, and easily causes product bad.
Traditional technique chip removal weak effect, because Tool Design is reasonable not, easily overstocks at endoporus, causes interior hole dimension and fineness bad;
And endoporus of turning, because endoporus has different step surfaces, so must adopt multi-cutter process, goes wrong cutter as any one, will cause product defective.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of all waste materials and discharges endoporus with the state at broken end with cutter, avoid interior hole dimension and fineness to produce bad, adopt special purpose machine tool and tool sharpening, one-shot forming, avoid occurring cutter relieving phenomenon, dimensionally stable, there will not be the whirlwind chip cutting technology of cutter relieving phenomenon.
The present invention is achieved through the following technical solutions: a kind of whirlwind chip cutting technology, it is characterized in that, and comprise the following steps:
(1), blank material is screened, check, according to the specific requirement of product, carries out corresponding Incoming Quality Control to blank, and chooses suitable size blank material;
(2), select suitable profile milling cutter, the material of this cutter is K44, the quartering in the middle of cutter head, the maximum gauge 22mm of this cutter, the diameter 20mm of blade place, the front end of cutter is provided with helicla flute, adjacent helicla flute bottom width 0.5mm, and the helical angle of this cutter is 10 °, the rear end retained part diameter of cutter is 16mm, cutter entire length 82.5mm, the middle of cutter offers the through hole that a diameter is 4mm, and the blade anterior angle of this cutter is 8 °;
(3), first blank material overall diameter is carried out to roughing, stay the allowance for finish of 1mm;
(4) first with drill bit, workpiece is holed, in the time that diameter of bore arrives preliminary election diameter, change 3NT profile milling cutter;
(5) be drilled in this through hole, iron filings are discharged inner hole of workpiece with the state at broken end with the helicla flute of cutter, and the bottom profile of this through hole is identical with the exterior contour of profile milling cutter, and then realize the endoporus processing settling at one go, dimensionally stable, there will not be cutter relieving phenomenon;
(6) after endoporus turning, change 90 ° of right angle lathe tools the overall diameter of blank is carried out to fine finishining, after reaching, then remove acute angle burr to dimensional accuracy, surface treatment can be processed according to client's requirement.
As preferred technical scheme, the model of described profile milling cutter is 3NT profile milling cutter, and this lathe tool is selected special endoporus turning lathe tool, and band spiral cutting edge, in when cutting, for the inner hole of workpiece turning of step surface, without changing other lathe tool.
As preferred technical scheme, the exterior contour of described 3NT profile milling cutter is helical form, and spiral fluted cross section is trapezoidal.
The invention has the beneficial effects as follows: all waste materials of the present invention are discharged endoporus with the state at broken end with cutter, avoid interior hole dimension and fineness to produce bad, adopt special purpose machine tool and tool sharpening, one-shot forming, avoid occurring cutter relieving phenomenon, dimensionally stable, there will not be cutter relieving phenomenon.
