Description
Technical field
Processed the present invention relates to a kind of Mechanical processing of casting method, more particularly to by hierarchical layered, cutting extrusion cladding
The mach method of casting.
Background technology
At present, there is the metal casting of blow hole defect after the machining operation, substantial amounts of pin hole, shadow can be presented in finished surface
Ring outward appearance and sealing property.Conventional processing methods are to divide thick, finish-milling to complete faying face by face milling cutters to process, and roughness exists
Clearly, the reason for casting produces pin hole is extremely complex for surface pinholes during below Ra0.8, and people use such as aluminium ingot drying, led to
The methods such as nitrogen dehydrogenation, cap pouring port improvement, all do not solve as above problem thoroughly, aluminium alloy castings is engaged in processing on the market now
During face, just as needle pore defect, highest has 50% or so product rejection processing, how to eliminate cast(ing) surface pin hole and improvement adds
The problem of work face outward appearance turns into the urgent need to address.
The content of the invention
To solve the above problems, the casting that the present invention provides a kind of hierarchical layered, cutting extrusion cladding is processed is mach
Method, this method can avoid the cast(ing) surface during machining casting from producing pin hole, so as to improve machined surface outward appearance, give
Faying face can produce preferable sealing effectiveness.
The present invention is realized using following technical scheme：A kind of casting machine-tooled method, it uses compound cutterhead, passes through layering
Classification, cutting extrusion cladding process；It is divided into three-level blade on cutterhead circle diameter to process from outside to inside successively, radius value
Reduce successively, form ladder milling；Three layers of different depth step are also classified into cutterhead axial direction blade to be processed successively,
Had the following steps during fixturing blade：
Step one：At least four rough milling cutter blades are symmetrically mounted on cutterhead on tool setting gauge, the rough milling cutter blade processing
Radius is R63, and the rough milling cutter blade rough mills surplus for removal, and it rough mills surplus △ P1 for 0.5mm；
Step 2：At least a piece of precise cutter is arranged on cutterhead on tool setting gauge, the precise cutter radius of machining
For R62, the precise cutter is higher than rough milling cutter blade 0.2mm, and the precise cutter is used to remove finish-milling surplus, its finish-milling surplus △
P2 is 0.2mm, and t1 is 1.0mm；
Step 3：On tool setting gauge at least a piece of fillet blade be arranged on in the symmetrical cutter spacing of precise cutter, it is described
Fillet blade is the extruding smoothing band of radius 0.5, and the fillet blade radius of machining is R60, and the fillet blade is higher than finish-milling
Blade 0.1mm, the fillet blade is used for extruding allowance, and its extruding allowance △ P are 0.1mm, and t2 is 2.0mm.
The radius R of rough milling cutter blade, precise cutter and fillet blade is selected according to cutterhead size and processing plane sizes,
The radius value of rough milling cutter blade, precise cutter and fillet blade is reduced successively, and it forms ladder milling.
After above-mentioned technical scheme, the present invention has following beneficial effect.
（1）, this method use rough milling cutter blade, precise cutter and fillet blade be arranged on cutterhead, its is simple in construction, lead to
Thick, essence, the extruding step of smoothing three is crossed to process successively with regard to three-level can be formed.
（2）, it is easy to use using this method, if after blade is adjusted, with usual cutterhead use.
（3）, this method remove pin hole effect substantially, cast steel can thoroughly be eliminated by this cutting extrusion cladding process technology
And the surface pinholes defect such as aluminum casting, surface roughness can fully meet user to outward appearance and sealing requirements up to R0.8.When
When user requires that machined surface roughness Ra is more than 0.4, it can make after above-mentioned machine with the processing of superfinishing plane rolling depression cutter
Scope must be used wider, this technology extends to all plastic materials, for example：Various non-ferrous metals, steel-casting etc..

Specific implementation method
According to Fig. 1 and Fig. 2, the present invention is a kind of mach method of casting.Using compound cutterhead 1, pass through layering
Classification, cutting extrusion cladding process；It is divided into three-level blade on the circle diameter of cutterhead 1 to process from outside to inside successively, radius
Value is reduced successively, forms ladder milling；Blade is also classified into three layers of different depth step and processed successively in the axial direction, in dress
Had the following steps during clip blade.
Step 1：Four 1# rough milling cutter blades 3 are symmetrically mounted on cutterhead 1 on tool setting gauge 2, it is ensured that four roughing milling cutters
The radius of machining of piece 3 is R63, and surplus △ P1 are rough milled for removing.
Step 2：A piece of 2# precise cutters 4 are arranged on cutterhead 1 on tool setting gauge 2, it is ensured that the processing of 1# precise cutters 4 half
Footpath R62, the precise cutter 4 is higher than the about 0.2mm of 1# rough milling cutter blades 3, for removing finish-milling surplus △ P2.
Step 3：A piece of 3# smoothing band R0.5 fillets blade 5 is extruded on tool setting gauge 2 to be arranged on and 4 pairs of 2# precise cutters
Claim in cutter spacing, it is ensured that the radius of machining R60 of 3# fillets blade 5, the 3# fillets blade 5 is higher than the about 0.1mm of 2# precise cutters 4, use
In extruding allowance △ P.
The 1# rough milling cutter blades 3,2# precise cutters 4 and the size of 3# fillets blade 5 are according to selected by processing plane sizes
Depending on cutterhead size, as long as radius value is reduced successively, ladder milling can be formed.
