3. Diversified Processing Materials & Material Advantages (Core Highlight)
As a professional CNC processing manufacturer, we break the limitation of single material processing and support full-category metal material customized processing. We select high-quality raw materials strictly, and match the most suitable materials according to customers' equipment working conditions, load-bearing requirements and service life standards, to ensure the best performance of the shaft parts.
3.1 Common Processing Materials & Applicable Scenarios
40Cr / 42CrMo Alloy Steel: The most mainstream industrial material. After quenching and tempering heat treatment, it has high hardness, strong torsion resistance and good impact resistance. Suitable for high-load transmission parts of machine tools, hydraulic equipment and heavy-duty automation equipment.
304 / 316 Stainless Steel: Excellent corrosion resistance, rust resistance and high temperature resistance. No deformation in humid and corrosive environment, long service life and maintenance-free. Ideal for new energy equipment, medical automation and outdoor industrial equipment.
6061 / 7075 Aluminum Alloy: Light weight, high toughness, good thermal conductivity. It can reduce equipment self-weight while ensuring structural stability, reduce equipment operation energy consumption. Widely used in robot arms and lightweight automation equipment.
SKD11 / DC53 Mold Steel: Ultra-high hardness and wear resistance, resistant to long-term high-frequency friction. Suitable for precision molds and high-speed operating transmission shafts.
H59 / H62 Brass: Good ductility, wear resistance and electrical conductivity, no burr after processing. Used for precision miniature transmission parts and electrical equipment accessories.
3.2 5-Axis Turn-Mill Processing Advantages
Different from ordinary 3-axis and 4-axis CNC processing, this irregular special-shaped integrated housing adopts professional 5-axis linkage turn-mill composite processing technology, with prominent process advantages:
One-clamp Forming, Zero Position Error: The complex structures such as inner holes, outer contours, flanges and mounting holes are completed at one time, avoiding cumulative tolerance errors caused by multiple clamping and positioning of traditional processes.
High Precision & Good Consistency: The whole machine is intelligently compensated for thermal error, with stable processing accuracy up to ±0.01mm, ensuring 100% consistent dimensions of each batch of parts.
No Secondary Processing Required: The surface is smooth and burr-free after processing, which saves secondary polishing and finishing procedures, shortens the delivery cycle and reduces customer costs.
3.3 Overall Product Core Strengths
Integrated One-piece Structure: No splicing and welding, high structural rigidity, strong shock resistance, suitable for high-frequency operation of automation equipment.
Customized Full-size Support: Fully customized according to customer drawings, supporting non-standard special-shaped structural part processing.
Strict QC Inspection: All products are inspected by CMM three-coordinate detector, with complete inspection data and full quality traceability.
