Cutting and drilling of tantalum

Are you interested in cutting and drilling tantalum and its alloys from the supplier company AvecGlob? Here you will find the necessary information on this topic.

General information

Cutting and drilling of tantalum is difficult due to the high plasticity of the metal, as a result of which there is a constant sticking of chips to the metal cutting tool. Therefore, it is more expedient to separate the tantalum blanks by the method of plastic shear, using cutting dies. In small-scale production, the cut can also be performed on mechanical circular saws or band saws, but a high percentage of waste limits the use of such cutting technology. The same restrictions correspond to drilling of tantalum and its alloys.

Before machining, tantalum is never annealed. The annealed tantalum adheres to the working surfaces of the cutting tool, contributes to the appearance of scoring, burrs and metal cuttings of the workpiece. As a result, the wear of the cutting tool is increased.

Tantalum medical grade usually does not contain alloying additives, and tends to harden during processing, which leads to significant limitations on the cutting regime. Therefore, in order to avoid too much heat generation during drilling and cutting of tantalum, lubrication is necessary. Lubrication is also necessary because when the feed of the cutting tool is high, the temperature in the processing zone rises sharply, which causes the material of the workpiece to self-ignite.

Supplier — AvekGlob Company — offers tantalum and its alloys in a wide range of brands and profiles, as well as at affordable prices from the manufacturer. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Lubrication of tantalum during cutting and drilling

Usually, the used lubricating and cooling liquids for tantalum processing are ineffective, even with their abundant supply to the treatment zone. The most effective are perchlorethylene, trichloroethane or molybdenum disulphide.

Drilling of tantalum and its alloys is recommended to be used only in extreme cases, while the material of the tool must be a hard alloy with tungsten carbide. The drill feed is usually set at a minimum level.

Supplier — AvekGlob Company — offers to purchase tantalum and its alloys in large names of brands and profiles in the assortment. Products can be bought at a price formed on the basis of European and world standards. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
