Manufacture of diamond tools for metal powder sintering Technology Articles | December 8 www.nikeprestoschweiz.com , 2011
Nowadays, diamond tools used in the manufacture of metal powder is mixed powder - except only cobalt powder. Cobalt powder in the sintered diamond tool used alone, without adding any other powder.

Mixed metal powder composition as the use of diamond tools and different. Understandably, when the diamond saw blade when cutting hard granite metal powder and mix required for cutting soft marble is different also, hard steel for honing and dressing diamond tools used in silicon carbide grinding wheel dressing tools required for both Metal powders are different. But not only is determined by the use of metal hydride powder composition. Conditions for the use of diamond tools will also affect the choice of binder components. For example, cutting the drive shaft of the engine power of the binder composition tools have a great impact. Here it is impossible to set out the various diamond tools required metal bond.
Diamond tools, sintered metal powder consumption of the largest blade. Therefore nike air presto schweiz , this article only saw the production of metal binding agent used in the discussion. Diamond saw blade production of the most commonly used metal powder are as follows: cobalt, copper, tin, iron, nickel, tungsten, tungsten carbide air presto schweiz , chromium, bronze, precious metals (zinc, manganese, silicon, silver, titanium) the use of the main diamond saw blade the following three aspects: 1. cutting soft stone such as marble. (2) cutting hard stone such as granite. 3 processing of other abrasive materials such as asphalt nike presto schweiz , refractory clay, concrete, etc.
For more than three uses, the former more or less blade binders contain cobalt. Previously, the saw blade cutting abrasive materials bonded mainly bronze or copper tin-based add some more or less cobalt. The combination of cutting hard materials contrast agent, cobalt-based more or less in order to add some copper tin or bronze. Very high on abrasive granite, plus a small amount of cobalt or tungsten carbide. Cutting abrasive materials Herren Nike Air Vapormax Flyknit 2018 Schuhe Olive Grün Schweiz , very resistant to use a combination of agents, usually tungsten, tungsten carbide or tungsten carbide cast. As the tungsten carbide tungsten carbide cobalt binder in the composition of a growing trend, corresponding to the sintering temperature is also more demanding, so the addition of a number of bronze or copper tin alloy, diamond sintering temperature can be controlled in an appropriate range.
As the prices of diamond saw blade, diamond tool industry began several years ago to find the right materials to replace expensive cobalt powder Damen Nike Air Vapormax 2018 Schuhe Rosa Schweiz , manganese powder especially the stone factory production for own consumption 31 ~ mm diameter to small saw blade, the main use of cheaper iron base or nickel-based binder. Professional manufacturer in the production of cutting blades and abrasive materials, granite saw blade area is conducted painstaking experiments to find other alternative to cobalt metal powder, powder, or at least reduce the levels of cobalt powder. The testing of the iron-copper - cobalt or nickel-copper-iron powder mixture, in some cases, also tested the corresponding pre-alloyed powders Herren Nike Air VaporMax Schuhe pure platinum Weiß Schweiz , in particular, is extremely fine-grained pre-alloyed powders, can reduce the sintering temperature of the ideal received the effect.
Binder aspects of research and development to today, boron powder people have developed certain aspects of the cutting performance than conventional cobalt-based binder cobalt-free or low-cobalt binder. Figure 1 shows three different cobalt binder and a low-wear cobalt binder performance comparison. Saw blade diameter of 400mm four diamonds used are 4050 head, diamond sawing rate 2.8mmin concentration of 22 18turn cutting depth of cut granite stone is BalticBrown. Four kinds of saw blades in addition to bond different from the rest are exactly the same process conditions produced four binders are low cobalt binder DIA BA SEV18 ultrafine cobalt powder (0.8um) extra-fine cobalt powder (1.4um) Cobalt (4um) shows that low-cobalt bond DIA BA SEV18 saw blade power consumption and the other three or less, the wear performance of the best. This test leads me to believe that the future manufacture of diamond saw blades, cobalt consumption can be reduced.
