Precision CNC Parts (Core insert)

• Core insert, material (H13), hardness (HRC48-50), resistant to cold and hot fatigue (not prone to cracking under repeated temperature changes), resistant to forming friction and wear, suitable for mass production, is a commonly used base material for injection molding / die casting molds. 
• Processing accuracy: The maximum tolerance can typically reach ±0.01mm, and a data report (CMM) will be provided. 
• Surface: (SPI-B3): Polished with 320-grit sandpaper, the surface has a slight sheen (roughness Ra ≈ 0.28 - 0.32 μm), and can cover up the machining marks.
• Lead time 3 days.

Brass parts and screw-inserts

• Types: Include brass screw insert  (with knurled/stepped structures), brass bushings, brass connection blocks, and brass locating pins.
• Material: Typically brass (e.g., H62/H65), featuring good electrical conductivity, wear resistance, and machinability.
• Functions: Used for fastening, transmission, positioning, or electrical connection in mechanical structures, suitable for high-precision assembly scenarios.
• Applications: Commonly found in transmission/connection systems of automotive parts, electronic devices, and precision instruments.

Precision CNC Lathe Parts

• Stainless steel (such as 304/316) has moderate hardness but excellent toughness. The high-precision servo system of the CNC lathe combined with carbide tools can well meet the processing requirements, especially suitable for the complex structures of this part such as multi-step outer circles, head embossing, and end holes.
• The automated processing of the CNC lathe can ensure batch consistency, and the surface finish of stainless steel (such as Ra0.8μm grade) can be directly achieved through CNC fine turning, reducing the subsequent grinding process.
