Production&Qualiy Approval

Since year of 2004,Chonghong has been engagded in precision machining and polishing fabricator of parts from industrial  sapphire, industrial ceramic and quartz.

We machine these materials to very precise tolerances (precisely at 0.005mm), flatness, perpendicularity,parrallelism,wedge and roundness or cylindricity. Our customers
typically have very tight tolerance requirement in some critical applicaion in these  materials. We  have full capability to grinding and polishing(including CMP polishment)spherical radius parts (such as sapphire tube,sapphire dome) and minimum orifice hole at dimension 100 micron in a variety of hard materials, both inside and outside diameters
to meet optical requirements.

Chonghong features include:

  1. Extremely high accuracy and tight tolerance borehole machining
  2. High speed laser drilling machining
  3. High speed 5-axis CNC center for high-precision machining of the most complex parts
  4. Automated centerless grinding
  5. Automated  slotter maching
  6. Hole Polishment maching
  7. Sapphire material slicing
  8. Windows Lapping&Polishing(Double&Single Side)
  9. High efficiency/low cost volume production
  10. Low-volume prototype machining
  11. RoHS and REACH compliant
