Products Description
Tungsten heavy alloy Grinding Quills is an alternative to tungsten-carbide heavy metal grinding quills for better performance and longer tool life. It is also used for boring bars, grinding quills, Arbors, Spindles, Tool Holders, and Shanks to reduce vibrations and chatter.
Tungsten heavy alloy Grinding Quills are made of Tungsten heavy alloys which have good machining properties, excellent radiation resistance, lower expansion coefficient, high strength and modulus of elasticity. Tungsten heavy alloys (WHA alloy) can be made into various shapes, but the most commonly used shape is a round rod that undergoes thermal mechanical treatment to improve its mechanical properties. Tungsten heavy alloys (WHA alloy) is made by forging tungsten alloy rods, greatly improving their tensile strength, with a strength ranging from at least 1050 megapascals to 1200 megapascals.
features
High Density and Strength:
Tungsten heavy alloy has a density of 17.0-18.5 g/cm³, much higher than ordinary steel. This gives the grinding rod more mass in the same size, helping it absorb vibrations better and improve machining stability.
Good Vibration Damping:
Because of its high density, tungsten alloy grinding rods reduce vibrations and chatter during machining. This is especially important for high-precision grinding.
Excellent Thermal Conductivity:
Tungsten alloy has high thermal conductivity. This means the tool can dissipate heat better, extending its service life.
Machinability:
Tungsten heavy alloy can be processed using traditional machining methods. This allows the grinding rods to be customized for specific needs.
Durability:
Compared to pure tungsten, tungsten heavy alloy is tougher and less likely to break. This makes it more durable in use.
applications
Metal and Wood Processing:
Tungsten heavy alloy grinding rods are widely used in metal and wood grinding. They effectively reduce vibrations and chatter during processing, improving machining accuracy.
Aerospace and Automotive Manufacturing:
In aerospace and car manufacturing, these rods help produce high-precision parts like engine components and transmission parts. Such parts require precise machining to ensure performance and reliability.
Medical Equipment Production:
In medical device manufacturing, tungsten alloy grinding rods are used to make precision components. Examples include X-ray collimators and radiation shielding parts for therapy equipment.
Precision Machinery Manufacturing:
For high-precision machinery, these rods help create accurate parts like bearings and gears. These components need precise machining to function reliably.
