Specific embodiment
The preferred embodiments of the present invention are specifically described below in conjunction with the accompanying drawings, wherein, accompanying drawing constitutes the application part, and
It is used to explain principle of the invention together with embodiments of the present invention.
A kind of carborundum side's mirror biscuit Pocket Machining method, carborundum side's mirror biscuit Pocket Machining method includes following step
Suddenly:
Step 1, paraffin is filled into carborundum side's mirror biscuit loss of weight chamber hollow space;
Step 2, the processing that groove is carried out using numerical control machining center;
Step 3, the carborundum side's mirror biscuit after processing is toasted, until paraffin is all removed.
In step 1, filling paraffin is by compound paraffin and rosin in mass ratio 10:1-5:1 configuration is formed, in the present embodiment
Using 8:1, packing volume, its object is to increase bottom portion of groove support, reduces cutter more than the half of the loss of weight cavity volume
The vibration produced during processing carborundum biscuit.
The raw material of compound paraffin is that every 1kg fully refined paraffin waxs are added:Palmitic acid 10g-20g, stearic acid 60g-80g, arachidic acid
10g-20g, polypropylene 2g-5g, polyethylene 8g-15g, beeswax 30g-60g.The raw material that paraffin is combined in the present embodiment is every 1kg
Fully refined paraffin wax is added:Palmitic acid 13, stearic acid 72g, arachidic acid 16g, polypropylene 4.0g, polyethylene 12g, beeswax 55g.In paraffin
The middle a small amount of stearic acid of addition, palmitic acid, arachidic acid can effectively increase the hardness of compound paraffin, compound paraffin is easier to machine
Tool is processed;Adding polypropylene and polyethylene can simultaneously increase the hardness and toughness of compound paraffin, imitate the damping of compound paraffin
Fruit is more preferably obvious;Beeswax is added, in addition to it can increase toughness, moreover it is possible to make to meet paraffin surface more preferably smooth, it is ensured that after processing
Precision and the roughness told somebody what one's real intentions are.
Fully refined paraffin wax is 58# fully refined paraffin waxs, 60# fully refined paraffin waxs are mixed by any mass ratio, using 58# essences in the present embodiment
The mass mixings such as refining paraffin, 60# fully refined paraffin waxs.
In step 2, numerical control machining center uses the polycrystalline diamond milling cutter of Φ 10mm, and uses spiral way feed, choosing
The polycrystal diamond cutter for selecting this diameter range is based on to the cutting force of cutter and considering for Product processing efficiency.
In step 2, the initial amount of feeding is 1200mm/min, and the depth of cut is 0.1mm, and the amount of feeding and the depth of cut are with processing
Carrying out be gradually reduced, and be directly proportional to the thickness of bottom portion of groove, the final amount of feeding is decreased to 600mm/min, and the depth of cut subtracts
As low as 0.05mm.During processing is carried out, bottom portion of groove thickness is gradually decreased, the amount of feeding and penetration of a cutting tool using processing beginning setting
Amount can increase the vibration of bottom portion of groove, now reduce the amount of feeding and bite, it is possible to decrease bottom portion of groove vibrates, it is to avoid carborundum side
Damage is produced during mirror biscuit Pocket Machining.
In step 3, the temperature of baking is 100 DEG C, and heating rate should keep 3-5 DEG C/min to setting in paraffin subtractive process
Temperature, temperature is too high to cause carborundum side's mirror biscuit to ftracture.
In step 3, the paraffin of removing is reclaimed, and reused.
The carborundum Fang Jing shaped using carborundum side's mirror biscuit Pocket Machining method, carborundum Fang Jing are provided with
Groove, groove diameter is more than Φ 378mm, and depth is more than 5mm, and bottom thickness is less than or equal to 6mm, distance from bottom loss of weight chamber upper surface
Hollow distance is more than 60mm, it is desirable to machining accuracy ± 0.2mm.
A certain carborundum side's mirror biscuit is processed using the method for the present invention, it is specific as follows:
The processing of carborundum side's mirror biscuit loss of weight cavity segment is completed first, and the chip inside loss of weight chamber must be complete with dust catcher
Portion is drained only, and heating paraffin is fused into liquid to 100 DEG C, first adds a small amount of vasoliniment, it is to be solidified after add again, repeat
This operation accounts for more than half of loss of weight cavity volume until adding paraffin volume, you can stop operation.
Secondly the polycrystalline diamond milling cutter of selection Φ 10mm, during square mirror biscuit Pocket Machining, starts to enter using spiral way
Knife is processed with the 1200mm/min amount of feeding, the bite of 0.1mm, and when being machined to 4mm depths, the amount of feeding is adjusted to 600mm/
Min, bite is adjusted to 0.05mm and is processed, and pilot process can be adjusted within this range.
After the completion of last carborundum side's mirror biscuit whole feature machinings, being placed in can be in the baking oven of setting program, and setting heats up
5 DEG C/min to 100 DEG C of insulation of speed removes paraffin in 2 hours, and the paraffin of removing is reusable.
In sum, a kind of carborundum side's mirror biscuit Pocket Machining method is the embodiment of the invention provides, using the present invention
Processing method the yield rate in square mirror biscuit process can be improved to more than 95%, reduce carborundum Fang Jing after sintering
Processing capacity, production efficiency can improve 3-5 times.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any one skilled in the art the invention discloses technical scope in, the change or replacement that can be readily occurred in,
