Precision custom per drawing supported, one-stop service from sample to mass production.
Precision Machined Parts Product Description
Knurled step shafts are critical transmission and positioning components in HVAC pumps, industrial pumps, and fluid equipment. Our products achieve multi-step one-pass forming through precision CNC turning, ensuring accurate control of each step diameter and coaxiality. Knurling process provides reliable gripping or press-fit surface, flange structure simplifies assembly with couplings or impellers. High-quality carbon steel and zinc plating surface treatment, suitable for long-term operation environments of pump equipment. We provide complete custom services from drawing review to batch delivery.
