1.High-Precision 5-Axis CNC Machining with Ultra-Tight Tolerance Control
Our motor rotor support is manufactured by professional 5-axis CNC machining, achieving an overall dimensional tolerance of ±0.02 mm and a bolt hole position accuracy of 0.03 mm. The high-precision process ensures the rotor assembly coaxiality ≤0.05 mm, meeting the strict assembly requirements of large motors and completely eliminating assembly gaps caused by machining errors.
2. Customized Machining Design for Multi-Industrial Scenarios
We support customized design of diameters from 3.2m to 7.8m and exclusive structures according to customer motor parameters, with personalized adjustment of rib layout and welding positions available. The industrial-grade machining process is perfectly adapted to various application scenarios of heavy-duty industrial motors such as wind power and hydropower, meeting all customized production needs.
3. Integrated Machining & Heat Treatment for Enhanced Structural Performance
The product adopts an integrated CNC rough and finish machining process, combined with overall normalizing and tempering heat treatment to ensure uniform material stress distribution. The surface hardness after machining reaches HB220-250 with a yield strength of ≥550 MPa, and its structural strength and durability are far superior to rotor components processed by a single process.
4. High-Precision Segmented Structure for Easy & Efficient Assembly
The splicing surfaces of the segmented support are precision-machined with a flatness error ≤0.01 mm/m. Matched with CNC-machined positioning pins and bolt holes, it enables fast and accurate splicing, reducing on-site assembly time by 40% compared with traditional machined products and greatly improving the assembly efficiency of large motor rotor systems.
5. Professional Surface Machining Treatment for Corrosion & Fatigue Resistance
After precision machining, the product is additionally treated with shot peening and electrostatic spraying, with the machined surface roughness controlled at Ra1.6-Ra3.2. This treatment increases the fatigue strength of the workpiece by 32% and achieves IP65 corrosion protection, ensuring stable operation in harsh industrial environments for more than 25 years.
