The production of surface-polished tungsten tubes and rods involves several key steps, including the production, forming and surface treatment of the tungsten material. The following is a general overview of production methods for surface-polished tungsten tubes and rods:

1. Tungsten powder production: This process first produces tungsten powder through hydrogen reduction of tungsten oxide or ammonium paratungstate. The purity and particle size of tungsten powder are key factors in determining the quality of the final product.

2. Compaction and sintering: Use a hydraulic press or other compaction methods to press the tungsten powder into the desired shape. The compacted tungsten is then sintered in a high-temperature furnace, binding the particles together to form a solid tungsten structure.

3. Shaping: The sintered tungsten is further processed through extrusion, rolling or drawing to obtain the required shape and size of tubes and rods.

4. Machining and polishing: The formed tungsten tubes and rods are machined to achieve the required size and surface finish. This may involve turning, grinding and polishing to create a smooth and polished surface.

5. Quality Control: Throughout the entire production process, quality control measures are implemented to ensure that materials meet purity, size and surface finish requirements.

It is important to note that producing tungsten tubes and rods with polished surfaces requires expertise in handling tungsten because it is a hard and brittle material. Additionally, machining and polishing processes are critical to achieving the required surface finish and dimensional accuracy.

Specific production methods may vary depending on the manufacturer's capabilities and final product requirements. If you have specific questions about the production methods of polished surface tungsten tubes and rods, or need more details, please feel free to ask!
