For a busy aircraft components manufacturer
milling and turning short runs of precision parts, shorter cycle
times and quicker tool changes mean greater profitability.
Crissair, Inc. in Palmdale, Calif. turned to tool supplier
Sandvik Coromant to help cut milling time on one alloy steel
hydraulic body 63 percent. The success led to a broader
Productivity Improvement Program that identified $87,000 in
potential annual savings, and ultimately to a huge $600,000
payoff by introducing a quick-change modular tooling system.
Crissair has produced precision fluid
control components for civil and military aircraft since 1954.
General Manager, John Semione explains, “We have manufactured
our products for nearly every airframe manufacturer and major
subcontractor in the industry. Crissair prides itself in its
flexibility to design custom valves to meet specific customer
requirements. Because we have design, manufacturing and test
capabilities within our facility, we can create and quickly
deliver various types of valves to meet any particular customer
application.”
Components are machined from 17-4, 15-5, and other alloy steels,
300 Series stainless, Inconel, titanium, and aluminum. The
company has developed more than 10,000 proprietary designs for
its customer base, of which, 3,500 are still active. Semione
continues, “Since most items are produced in short runs of 15 to
30 pieces, short cycle times and fast changeovers from one part
to another are essential to...
