Current, diamond fretsaw piece the production of knife head is in abroad common use suppress of pulverous metallurgy law to shape craft. This craft has a few sides adverse element: The diamond that the knife head place that 1) this craft makes uses asks to have higher grade; The design of head of knife of suppress of law of 2) pulverous metallurgy to carcass recipe and craft requirement are stricter, otherwise diamond falls off the phenomenon will be very common, create huge waste thereby; Law of 3) pulverous metallurgy produces a process to be able to make diamond produces fire damage to affect the performance with original diamond, further effect curiums piece cutting function. In recent years, study worker is aimed at the talent of difficult treatment stone with certain higher hardness, used all sorts of methods to have a large number of research to making knife head, the cutting function of knife head is improved somewhat. But the problem with low utilization rate of the diamond in knife head still did not get very good settlement, and production cost is very high. The article put forward to eletroplate to combine production diamond fretsaw with pulverous metallurgy piece the new method of knife head, undertook in the light of concerned technology issue preliminary research is mixed discuss. Production method pursues graph of principle of 1 clamping apparatus is used eletroplate honest legal system takes diamond compound piece choose 1mm thick copperplate to serve as matrix, the course removes oil, after cleaning, with clamping apparatus clip is held firm. Clamping apparatus breaks up copperplate it is numerous 24mm × 12mm is small, every small surface classics is uncovered after compound electrodeposit diamond become namely one compound piece, clamping apparatus principle is shown 1 times like the graph. Regard cathode as copperplate, after connecting electrodeposit Ni or Ni-Co metal, in make the same score put copper coin to go up to scatter a diamond equably (say to go up arenaceous) , with deposit of small current density fall after proper time arenaceous, increase current density to undertake adding thick plating subsequently, in diamond major or be buried by deposit metal entirely fashionable, take out clamping apparatus, clean clean with water, it is good to uncover next deposits from copperplate matrix compound piece, stoving hind reserves. Graph the 2 diamond that produce to eletroplate are compound piece exterior form appearance. Diamond of felt of pulverous metallurgy law is compound piece choose powder of a few kinds of metals, pink of copper of low melting point is given priority to, cheap metallic pink is complementary. Ability of treatment stone talent differs character, the metallic pink that should choose to differ and deserve to compare. The choice mould dimension of the means that fit a pattern is 9mm of × of 24mm × 12mm. Use diamond is compound piece replace original abrasive layer, every compound piece dimension is 24mm × 12mm, its ply basically depends on eletroplate process increases generous deposit time and current density mediumly, with compound piece in the diameter of bead of use King Kong stone mill is worth close. Assemble number of plies to be able to undertake adjustment character according to machining stone talent ability. Grain of treatment stone material is bigger, number of plies is smaller. Because the choice of agglomeration craft basically uses pink of metal of low melting point to serve as binder, because this can use inferior firing temperature, compare at law of common pulverous metallurgy agglomeration, can lower the fire damage rate of diamond. Also can use cold pressure shape, vacuum agglomeration craft. Graph 2 compound the main characteristic of a new method of exterior form appearance reduces diamond fire damage to eletroplate craft production diamond is compound piece nonexistent the fire damage to diamond, when hot pressing of use metal powder joins, can use relatively inferior hot pressing temperature, thereby but the fire damage that certain level land reduces pair of diamond. The diamond that the agglomeration difficulty that reduced knife head produces to this craft curiums a knife head, abrasive hold problem by eletroplate craft decision, get good hold easily. Diamond oxidation problem need not consider, and firing temperature is inferior, because this reduced agglomeration difficulty. Production knife head is sharp spend good report plating diamond product is sharp had spent, can improve treatment efficiency. Can use product of diamond of the tall thick plating that spend report to be able to use very high abrasive concentration, pulverous metallurgy law can not achieve this. Produce this inferior electricity plating diamond is compound piece preparation can choose diamond of Ⅱ , Ⅲ low grade, can reduce diamond fretsaw greatly piece knife head makes cost. Aureate firm Shi Fu closes discussion report piece because quality problem was used eletroplate compound piece replace diamond abrasive layer, so compound a diamond that go up become curium the principal part that cuts treatment. Compound piece the foundation that quality is a head of craft production knife, have crucial effect to final knife head quality. Compound piece quality depends on the diamond quality that when eletroplating, chooses and eletroplate the technology control of the process. The requirement eletroplates the process can be deposit a detailed carcass data, have good hold to the diamond of solidify amid. This depends on the choice of deposit alloy, eletroplate the choice of craft parameter, on arenaceous craft, go up among them arenaceous craft decided compound piece diamond chroma. Eletroplate goods allows to use higher abrasive concentration, this is one of large dominant positions. This craft cut an experiment to decide those who contain diamond of distinct size, grade is compound through curiuming a medium diamond chroma. Compound a felt issue with metallic bond is complex piece with the felt between metallic bond it is to pass the agglomeration of metallic powder to come connective, the metal is so pulverous layer and compound an adhesion between abrasive layer it is very important, decided the feasibility of this technique, cut processability to be able to have main effect to curiuming. Consider to make clear, if eletroplate deepness of embedded of diamond of compound a short while is deeper, criterion metal and compound a join translate into between eletroplate the join between carcass metal stuff and stuff of pulverous metallurgy metal, both the adhesion between is good, can assume curium the load when cutting. The place on epilogue put together is narrated, the knife head that uses this craft to make has cost low, machine the dominant position with high efficiency, its produce application to will produce good economic benefits. Because this eletroplates,with pulverous metallurgy combinative method makes diamond circular saw piece knife head has certain promotion to use value. CNC Milling CNC Machining
