Turned Hot Forged Parts

Why choose us?

1. Precision turning processing

Japan Tsu machine machining, straightness ≤0.01mm/100mm

Swiss Baomei CNC lathe, repeated positioning accuracy of ±0.003mm

2. Special heat treatment

Solution treatment (1050℃ water quenching) : restore the best corrosion resistance of the material

Low temperature stress removal (300℃×2h) : eliminate processing deformation

3. Surface strengthening technology

Electrolytic polishing: the surface roughness can reach Ra≤0.4μm

PVD coating (optional) : Friction coefficient of TiN coating is reduced to 0.08

4. Whole process inspection

Air gauge aperture (accuracy ±0.001mm)

Roundness measuring radial runout (≤0.005mm)

Spectral analysis ensures material composition (precise Mo content control)

Product introduction

This large CNC machining service is equipped with a 5-meter vertical lathe and gantry machining center, with superior machining capacity (maximum turning diameter of Ø2000mm, workpiece weight ≤8 tons), and can handle a variety of materials such as aluminum alloy (5083/7075), stainless steel (304/316L) and titanium alloy. Through constant temperature workshop (20±1℃) and laser compensation technology to ensure large size accuracy (±0.05mm), provide wind power gearbox, ship thrusters and other large parts processing, with laser quenching (hardness ≥HRC55) and other special processes to meet the energy, rail transit and other industries of heavy precision machining needs.
