About Us

Who we are

JC Precision Machining was founded in January 1, 1995 by Carlos A. Cajas and his wife Maricela Cajas in Ontario, California. From its humble beginnings, the machine shop started with just one sole CNC machine. On March of 1997, the company expanded by moving into a 5,000 square foot building and began adding more machinery to meet business growth. JC Precision was incorporated in California as JCPM in October 1, 1998. To pursue growth and diversification, a 12,000 square foot building was purchased in Rancho Cucamonga in November of 2004. At the request by one our largest customers, JC Precision was certified by the Small Business Administration as an 8 (a) minority owned, small disadvantaged business.

JCPM, Inc. has developed its government contracting capabilities by becoming registered with Central Contracting Registration (CCR) and certified by the United States/Canada Joint Powers Authority.
