shenxing ceramic high precision solid rod part CNC machined ceramic pin

High-precision CNC machined alumina ceramic components​ are parts made from aluminum oxide (Al₂O₃) that are shaped and finished using Computer Numerical Control (CNC) machining to achieve extremely tight tolerances, complex geometries, and superior surface finishes. Alumina is chosen for its exceptional hardness, wear resistance, electrical insulation, and thermal stability. CNC machining is necessary because alumina is too hard and brittle to be shaped by traditional methods after it's fired.  

CNC machined ceramic pin​​ is a premium, high-performance component selected for its unparalleled wear resistance, corrosion immunity, and stability in harsh environments. While the initial cost and design care are higher, it is the optimal solution when the failure of a standard metal pin leads to excessive downtime, contamination, or maintenance costs.

Ceramic rotor is a high-performance rotating component made from advanced ceramic materials (predominantly alumina, zirconia, or silicon nitride). It integrates exceptional wear resistance, corrosion resistance, and high-speed stability, replacing traditional metal rotors in precision and harsh working environments.     Shape: Cylindrical, impeller-shaped, or custom-designed (matching equipment rotation requirements).   Size Range: Diameter 5–200 mm, length 10–300 mm (micro-rotors for precision devices to large rotors for industrial pumps).   Precision Tolerance: Dimensional tolerance up to ±0.003 mm, concentricity ≤0.005 mm, ensuring smooth high-speed rotation.   Surface Finish: Ra ≤ 0.2 μm, with optional coating (e.g., PTFE) for enhanced lubricity in specific applications.

Common Applications Include: 1.Severe Service Ball Valves & Plug Valves:​ The protection tube would be placed around the valve stem. It prevents the corrosive, abrasive, or high-temperature fluid from eroding the metal stem, ensuring smooth operation and preventing seizures or leaks. 2.Knife Gate Valves:​ Used in industries like mining and pulp & paper to handle abrasive slurries. The tube protects the gate and stem mechanism from rapid wear. 3.Sensor Protection:​ It can serve as a thermowell or a sheath for temperature sensors (thermocouples, RTDs) or pressure sensors inserted into a pipeline. The alumina ceramic protects the sensitive sensor from chemical attack and physical damage. 4.High-Temperature or Corrosive Environments:​ Ideal for industries like: •Chemical Processing:​ Handling acids, alkalis, and solvents. •Petrochemical:​ In refineries with corrosive hydrocarbons. •Power Generation:​ In systems with high-temperature steam or flue gases. •Mining and Mineral Processing:​ For abrasive slurries and tailings. •Steel and Metal Production:​ In high-heat furnaces and handling molten metals.
