Award winning supplier that specializes in machining
Military, Aerospace, and Commercial parts


We work hard to meet every customer's needs and make every effort to assure the highest quality product.

In 1989, Jesse and Rudy Alvarado started a machining business in Jesse's garage with just one machine. 30 years later, that garage shop has evolved into a machine shop complete with 14 CNCs and an office for Administration and Metrology.

Located in Lancaster, California (60mi north of Los Angeles), we’ve made parts for military fighter jets and the Apache Helicopter, as well as many other Aerospace projects. We’ve also worked on various commercial projects outside of the aerospace industry.
