Tungsten Heavy Metal Boring Bar
Tungsten heavy metal boring bars are manufactured with alloys of 90% – 97% tungsten. Their surface can be either a sintered form, machined form, or polished form.
Tungsten heavy metal boring bars have similar properties to tungsten carbide boring bars, but the different chemical compositions can help to reduce brittle. The high density and tensile strength of tungsten heavy metal boring bars allow them to be great at resisting the chatter. It also has the name chatter-free boring bar or super chatter-free boring bar.
Tungsten heavy metal boring bars are widely used for boring bars, grinding mandrels, tool shafts, and types of precision tools that need vibration damping to ensure smooth running.
Tungsten Heavy Metal Tool Holder
Tungsten heavy metal tool holders are manufactured with alloys of 90% – 97% tungsten. Their surface can be either a sintered form, machined form, or polished form.
Whether you are riveting, drilling, grinding, or lathing: machining lightweight, soft materials can often result in oscillations, vibrations, or loud noise emissions.
The combined high density, high elastic (Young’s) modulus, and machinability of tungsten heavy metal tool holder make it a great material for chatter-free boring bars and grinding quills.
