Turning of tantalum

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

Features of turning processing of tantalum and its alloys

Tantalum turning 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, turning can be performed on lathes, and for mass production use lathes and semiautomatic machines. However, a high percentage of waste restricts the use of such technologies, therefore, technological operations of bulk wasteless stamping are more often used, which are used for round-billets: embankment or extrusion / pressing.

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 turning 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 billet 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.

Turning modes

Turning operations should use tools from cemented carbide, and also use increased cutting speeds (high-speed cutting). The tools should be sharp and ground with the same positive angle value as the tool. A minimum turning speed of about 250 mm per minute will be sufficient for most turning operations. Slower speeds can lead to metal rupture.

Proper lubrication should be used as a shearing medium, and the technological grease must be constantly fed to the workpiece. In addition to turning, it is advisable to perform thread cutting operations on lathes.

Supplier — AvekGlob Company — offers to purchase tantalum and its alloys in a variety of brands and profiles of blanks and semi-finished products 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.
