Preparation for machining

Zirconia workpieces can be machined both cold and hot. However, when heated to temperatures above 250...300°C, zirconium actively interacts with air oxygen. The formed oxide films worsen the machinability of metal. Therefore, to improve zirconium cutting and drilling, ingots are deburred on the machine prior to treatment. Evek GmbH offers to buy zirconium billets and forgings. Economically advantageous prices from manufacturers are available. The supplier guarantees a prompt delivery of products to any location specified by the consumer.

Guillotine chopping

Chopping of zirconia with guillotine is performed according to the marking or stop, which provides a high level of accuracy of the cut without jagging and crumpling of edges. Installation of special knives allows not only cutting of sheets, but also channels and angles. Low cost and very high productivity are the main advantages of guillotine metal cutting.

Advanced technologies

The most popular in recent years are hydro-abrasive cutting and laser cutting and laser drilling. These methods are especially relevant in the production of flat metal products, they are especially effective for obtaining small holes and cavities in zirconium billets. These methods are used today not only in relation to such a ductile metal as zirconium, but also for cutting steel alloys. Water-abrasive metal cutting uses a mixture of abrasive and water as the cutting tool

Other technologies

Band saw cutting of large section tubular products and circular (circular) saw cutting are used. Mechanical /friction saws are used for cutting zirconium billets. If necessary to reduce waste, use precision shear cutting on dies with minimal axial and radial clearance between the knives.
