Abstract
The invention discloses a PCD (Poly Crystal Diamond) spiral reamer. According to the technical scheme, a tool body is made of a hard alloy bar material which is provided with a single water cooling hole; two main chip grooves (spiral grooves) of which the spiral angles are 8-10 degrees are formed; three guiding edges are formed behind each main chip groove at the intervals of 30 degrees; PCD is embedded into a main cutting edge; a cutting liquid can be sprayed onto a PCD cutting edge through water cooling holes in the main chip grooves; the diameter of PCD is 0.005 millimeters larger than the diameter D1 of the guiding edge; the circular edge of the PCD is 0.15 millimeters; the circular edge of the guiding edge is 0.5 millimeters; a PCD cutting cone is 0.3 (millimeters)*75 degrees; transition from a circular arc R0.1 to an outer diameter edge is realized; a PCD end face projects out of the tool body by 0.3 millimeters; an axial edge inclination angle is 8-10 degrees; an axial back angle is 7 degrees; a radial forward angle is 0 degree; a back angle is 13 degrees; the PCD outer diameter is backwardly tapered by 0.04-0.08/100; and a hard alloy guiding edge is backwardly tapered by 0-0.01/100. During processing of a complex interference hole of seven times of hole depth, the revolutions of the tool can be over 10,000 revolutions per minute, the circular degree of a processed hole is 0.007 millimeters, the surface roughness Rz is less than 0.4, and the hole accuracy is kept within IT7.
Description
Technical field
The present invention relates to a kind of machining tool, relate in particular to a kind of PCD spiral reamer.
Background technology
In the complicated interference of aluminium valve body hole processing, hole accuracy tolerance IT7, the circularity in hole is less than 0.01mm, because hole depth surpasses 5 times more than the diameter, and has the interference of a lot of intersection through holes, uses common reamer working (machining) efficiency slow, and waste product is many, and processing cost is high.
Summary of the invention
The present invention has overcome deficiency of the prior art, and a kind of PCD spiral reamer is provided.
In order to solve the technical problem of above-mentioned existence, the present invention is achieved by the following technical solutions:
A kind of PCD spiral reamer, cutter hub adopts the hard alloy bar in single water-cooled hole, leaving two helical angles is the main chip area (helicla flute) of 8 ~ 10o, every main chip area back is respectively with 3 guiding swords, the interval is 30o, PCD is embedded on the main cutting edge, water-cooled hole in the main chip area can be injected in cutting fluid on the PCD cutting edge, the large 0.005mm of PCD diameter D ratio guiding sword diameter D1, PCD circle sword 0.15mm, guiding sword circle sword 0.5mm, the PCD cutting cone is 0.3mm x75o, transits to the external diameter sword by circular arc R 0.1, and the PCD end face leans out cutter hub 0.3mm, axially cutting edge inclination is 8-10 °, axial relief angle 7o, radial rake is 0o, relief angle is 13o, PCD outer radius back taper 0.04-0.08/100, carbide alloy guiding sword back taper 0-0.01/100.
Because adopt technique scheme, a kind of PCD spiral reamer provided by the invention compared with prior art, has such beneficial effect:
Interfere the hole to add man-hour in the complexity of 7 times of hole depths, the cutter revolution can reach more than 10000 rev/mins, 0.5 millimeter of revolution feeding, 0.007 millimeter of the hole circle degree that processes, surface roughness Rz are less than 0.4, in the accuracy guarantee IT7 in hole, can improve machining status, boost productivity, improve circularity and the surface roughness in hole, reasonably reduced the production cost of unit.
