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

Features of tantalum machining

The metal adheres to the surface of the turning tools and causes surface damage to the workpieces, so only natural annealed tantalum is suitable for turning. The chemical composition of the workpieces is also important for successful machining: pure tantalum is less suitable for turning than tungsten, molybdenum and other alloyed metals.

Lubrication

During turning a considerable amount of heat is released on the surface, so turning is performed with abundant supply of lubricant. Lubricants such as perchlorethylene, trichloroethane or Moly-Dee are used instead of regular oil. The supply of lubricant should be continuous.

Accessories

Mineral-ceramic or high-speed steel tools are used when turning tantalum blanks. Spindle speeds of the lathe spindle not lower than 1750 rpm are recommended. 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.

Drilling and grinding

Drilling of tantalum is generally difficult. Carbide tungsten carbide drills are most suitable at 750...850 ^min-1. Grinding tantalum is extremely difficult, so only unground workpieces are used, and aluminum oxide is used as a grinding material.

Safety of machining tantalum

Since tantalum dust can have a risk of ignition upon contact with oxygen, chips are particularly dangerous. Spontaneous ignition is particularly flammable during drilling and turning. Accidental ignition of tantalum shavings also occurs when attempting to collect machining waste from this metal. The reason is that tantalum dust has a minimum ignition energy

Tantalum Dust

The explosiveness of tantalum dust is classified as high (Kst = 273). The minimum ignition energy (for both the dust cloud and the dust layer of tantalum powder) was also established. The structure of the tantalum shavings is such that it can increase the fire and explosion hazard, and affect the sensitivity to electrostatic sparks by increasing the surface area of the particles. The thin, conductive oxide surface layer of tantalum powder has a high resistivity, and generates an electrostatic charge when it rubs against conductive materials. Thus, the most possible cause of ignition is electrostatic discharge.
