CNC Crowning Grinder Achieves AAA Rating in Technology Commercialization Assessment

In June 2025, Sangnim MSP Co., Ltd. was awarded the highest possible AAA rating in the Technology Commercialization Assessment conducted by the Korea Technology Finance Corporation (KIBO).

The certified technology is our self-developed “Domestic CNC-Controlled Crowning-Type Heavy-Duty Roll Grinder (Spec-Up)” system.

What Does an AAA Rating Mean?

• AAA is the highest rating granted by KIBO in its technology commercialization assessments.

• The rating evaluates a company’s technological innovation, business feasibility, and stability. Only a small number of companies receive this prestigious certification.

• Sangnim MSP received top evaluations:
  ▶ Technological Competence: G1 (Very High)
  ▶ Business Risk: R2 (Low)
  These ratings confirm our status as a leading technology company in Korea.

What Is a Heavy-Duty Roll Grinder?

In steel manufacturing, a rolling mill is used to flatten or shape steel sheets. A core component of this machine is the roll, a large cylindrical metal part that must be processed with extreme precision.
A heavy-duty roll grinder is the equipment responsible for this ultra-precise machining, which directly affects product quality.

Our Technological Breakthrough

Sangnim MSP has successfully addressed long-standing issues that conventional grinders couldn’t solve:

• High-precision profile grinding

• Quality control in curved surface machining (e.g., crowning and cambering)

By applying domestic CNC control technology, we have replaced dependence on imported equipment and dramatically improved both precisi
