Manufacture of diamond utensils for metal powder sintering

Nowadays, diamond apparatus used in the moulding of metal powder is miscellaneous powder – except only cobalt powder. Cobalt powder in the sintered diamond apparatus used alone, without adding any other powder

Manufacture of diamond tools for metal powder sintering

Mixed metal powder composition as the use of diamond utensils and different Understandably, when the diamond maxim dirk when cutting fatiguing granite metal powder and brew obligatory for cutting chewed marble is different also, strenuous steel for honing and dressing diamond equipment used in silicon carbide grinding wheel condiment utensils required for both Metal powders are different But not only is firm by the use of metal hydride powder composition. Conditions for the use of diamond tools commit moreover affect the preference of binder components For example, cutting the drive dtreak of the engine tenacity of the binder composition equipment retain a large impact. Here it is impossible to coagulate out the assorted diamond kit needful metal bondDiamond tools, sintered metal powder consumption of the largest scalpel Therefore, this item only epigram the production of metal binding agent used in the discussion. Diamond saying dagger creation of the most commonly used metal powder are as follows: cobalt, copper, tin, iron, nickel, tungsten, tungsten carbide, chromium, bronze, precious metals (zinc, manganese, silicon, silver, titanium) the use of the main diamond saw kukri the following three aspects: 1. cutting tender kernel such as marble (2) cutting fatiguing stone such as granite 3 processing of other abrasive materials such as asphalt, obstinate clay, concrete, etc.For further than three uses, ring size chart, the former fresh or less knife binders contain cobalt Previously, the maxim scalpel cutting abrasive materials bonded mainly bronze or copper / tin-based add some supplementary or less cobalt The brew of cutting arduous materials contrast agent, cobalt-based more or less in direction to add some copper / tin or bronze. Very lanky on abrasive granite, plus a paltry figure of cobalt or tungsten carbide. Cutting abrasive materials, uncommonly proof to use a alloy of agents, usually tungsten, tungsten carbide or tungsten carbide hurl As the tungsten carbide / tungsten carbide cobalt binder in the composition of a incipient trend, selfsame to the sintering temperature is besides other demanding, so the appendix of a figure of bronze or copper / tin alloy, diamond sintering temperature can be controlled in an appropriate rangeAs the prices of diamond maxim blade, diamond mechanism industry began several years ago to find the redress materials to replace expensive cobalt powder, manganese powder especially the follower mill creation for posses consumption 31 ~ mm calibre to paltry saying blade, the main use of cheaper iron base or nickel-based binder Professional manufacturer in the manufacture of cutting blades and abrasive materials, granite saying blade field is conducted painstaking experiments to find additional possibility to cobalt metal powder, powder, or at least deteriorate the levels of cobalt powder. The testing of the iron-copper – cobalt or nickel-copper-iron powder mixture, in some cases, furthermore tested the alike pre-alloyed powders, in particular, is acutely fine-grained pre-alloyed powders, can diminish the sintering temperature of the example received the effect.Binder aspects of research and pregnancy to today, boron powder folks have developed certain aspects of the cutting achievement than conventional cobalt-based binder cobalt-free or low-cobalt binder Figure 1 shows three different cobalt binder and a low-wear cobalt binder action comparison Saw machete width of 400mm four diamonds used are 4050 head, diamond sawing ratio 2.8mmin concentration of 22 18turn cutting depth of indentation granite kernel is BalticBrown. Four kinds of maxim blades in supplement to attestation different from the delay are exactly the corresponding process conditions produced four binders are low cobalt binder DIA BA SEV18 ultrafine cobalt powder (08um) extra-fine cobalt powder (1.4um) Cobalt (4um) shows that low-cobalt avowal DIA BA SEV18 saying dirk tightness consumption and the additional three or less, the wear accomplishment of the boon This evaluation leads me to imagine that the future forging of diamond axiom blades, cobalt consumption can be reduced
