Are you interested in cutting and drilling tantalum? We offer to buy tantalum from the specialized warehouses of the supplier Evek GmbH with delivery to any city. Full compliance with modern quality standards. The supplier Evek GmbH offers to buy rare-earth metals, the price is optimal in this segment of rolled metal products.

Mechanical processing

In turning operations, tools made of high-speed steel should be used and high cutting speeds should be used (from 2500...3000 rpm). Lower speeds can lead to tearing of the tantalum workpiece. As an intermediate medium the use of technological grease is mandatory, and its amount must be increased. The same requirements must be met when milling tantalum workpieces. The use of cutters with a toothed profile that has significant back and side relief is recommended.

Drilling

When drilling, the point at which the working tool is to be inserted into the workpiece must be re-pointed in order to avoid waste of material. Due to the malleability of tantalum, metal-cutting equipment, rather than rolling machines, is recommended for the formation of threads. The company Evek GmbH offers to buy any rare-earth metals at the manufacturer's price. The supplier guarantees delivery of products to any destination.

Grinding

Grinding of tantalum is extremely difficult because the metal is plastic and easily adheres to the surface of the working tool. Effective grinding of tantalum is only possible with the use of grinding discs that have aluminum oxide (or any other material equivalent in its performance characteristics) on the surface.

Cutting

Most separating operations on tantalum are common and can be accomplished without difficulty. Two important characteristics of tantalum, however, should be borne in mind:

• Tantalum adheres intensely to metals such as copper, lead, and stainless steel. As a result, significant burrs, tears, metal tears, and other defects of the interface surface occur on the cut workpieces;
• Cutting tantalum billets should only be done when they are cold.

When cutting tantalum billets on press cutters or in dies, the gap between the blades and the workpiece and the die should not exceed 6% of the thickness of the metal being processed. It is desirable to perform cutting by periodically lubricating the blades with low-viscosity oil, perchloroethylene or trichloroethane in order to prevent tantalum chips from sticking on the working surfaces of the cutting tool.

Buy, bargain price

We offer to buy tantalum, the price - determined by the technological features of production without including additional costs. The website of Evek GmbH displays information on the latest arrivals of products. It is possible to order rolling of any metal. We invite to partner cooperation.
