Its implementation is, adjusts the quantity of thick and/or finishing tool as required and/or adjusts in 360 ° of scopes between any two adjacent cutters, promptly between the roughing tool, the angle between the finishing tool, between roughing tool and the finishing tool.
The quantity of described roughing tool and/or finishing tool is selected different quantity according to the diameter difference in processed hole.
Not five equilibrium arrangement in described 360 ° of scopes: the bottom surface of two relative roughing tools of roughing tool and the angle of transverse axis are 10 °, and the bottom surface of two relative roughing tools and the angle of vertical pivot are 12 °, 14 ° in addition.
Not five equilibrium arrangement in described 360 ° of scopes: the angle between each finishing tool is respectively 30 °, 32 °, 36 °, 40 °, 42 °, 35 °, 34 °, 41 °, 37 °, 33 °.
Described roughing tool relies on the profile of tooth below the cutter, and radial location is fixed, and relies on the inclined-plane axial location below the cutter and compresses cutter.
Angle between the described roughing tool, the quartering impartial in 360 ° of scopes distributes.
Described finishing tool A, B glue or shellac or epoxy resin adhesive are adhesively fixed.
Described finishing tool is fixing with scolding tin or the welding of copper welding compound.
Angle between the described finishing tool, ten impartial in 360 ° of scopes five equilibriums distribute.
Described common cutter hub is installed on the boring bar by middle tapered hole or on the knife bar, or installs and fixes by taper shank, or employing machine folder installs and fixes, and prevents that by the end face fluting cutter from rotating and transmitting moment of torsion.
Advantage of the present utility model is as follows:
By using this cutter, can on an equipment, workpiece be installed once, a feed is processed, and finishes the function of roughing and fine finishining two procedures simultaneously, makes production procedure more succinct; Improve the service efficiency of lathe, improved working (machining) efficiency; Because, reduced clamping times, the workpiece machining deformation is obviously reduced, the form and position tolerance precision obviously improves, thereby has improved machining accuracy.Possess significantly and cut down finished cost the superior function of raising crudy.
