BACKGROUND OF THE INVENTION. This patent relates to a process to convert slivers and fines (referred to as "SWARF" in the industry) from refractory metal (titanium and zirconium metal) belt grinding operations into a consolidated, safe to handle, raw material suitable for aluminum, magnesium and iron refractory metal master alloys, …Web

Dried swarf contains 20–50% of oil, 45–80% of metals and 1–5% of other materials. The contaminants found in tool grinding swarf cause technical problems in a remelt process. Nonmetallics create undesired slag in the metal remelt process. Oil, if presents above 3%, may burn in the melt. If the oil content is too high, the oil can burn ...Web

There are various kinds of swarf based on the manufacturing process that made the swarf. Fines and Filings are the tiniest flecks of material that most often come from grinding tools. Shavings range in size from the powder up to larger chips your cutting tool slices from a piece of metal. Turnings are the result of a turning process.Web

This could be explained by the composition of the grinding waste, called grinding sludge. Therefore, this research deals with the upcycling of the grinding swarf in a PM process. The grinding swarf are characterized by SEM and XRD and processed by a ball mill treatment and a Supersolidus liquid phase sintering process.Web

If the swarf is not removed, it can clog the coolant system over time and have an adverse effect on part finish. A coolant filtration system is an important component in helping to minimize these issues. ... This grinding process does not produce undesirable burrs on the part, which is particularly important on parts that have overlapping ...Web

In micro cutting process, the size effect is a dominant factor for material removal mechanism and chip generation physics. There are different types of chips but a particular type, stands out from the others due to its specificities: the spheroidal chip. It is often found in grinding and tribological tests.Web

Stainless steel swarf is a typical solid waste produced in the turning and grinding process of stainless steel, which contains a significant level of valuable metals, such as iron, chromium, and nickel [1, 2].However, due to the complex relationship of various phase compositions, the comprehensive utilization of valuable metals from …Web

SCCO {sub 2} extraction at 80 C and 340 atm shows that approximately 80% of the oil can be removed from swarf during a 60-minute process to produce a batch of recyclable steel, and that the phosphorus removal also reaches the required level. The cost of processing swarf using either aqueous surfactant washing or SCCO {sub 2} extraction …Web

Fluid use is very important in the grinding process because it reduces the effects of friction, removes heat from the work zone, and increases material removal. Most important, grinding fluid increases the material removal rate without increasing the damage to the surface of the workpiece. Many cutting fluids are available today, so it is wise ...Web
