Bourdelais Grinding Co., Inc.

Bourdelais Grinding Co, Inc is a precision grinding shop in Simi Valley, California. It does Blanchard grinding and double disc grinding. The company was established in 1972 by William and Edith Bourdelais. Brian Carrigan owned and ran it from 1985. In 2022, ownership passed to his children, Ian and Jillian.

Double disc grinding removes equal stock from both sides of a part. The site says it also relieves internal stress in the material, which makes the part easier to machine. Blanchard grinding is used for heavy stock removal, one side grinding, and parts too large for a double disc grinder.

The site lists tech specs for its Blanchard grinder. The capacity is 42 inches, with 26 inches under the wheel. An automatic saw cuts up to 14 inches square. The site lists size tolerances to .0002, flat and parallel tolerances to .0001, and a surface finish to 16 RMS.

The shop grinds aluminum, steel, titanium, copper, and brass. It also grinds stainless steels, aircraft alloys such as 4130 and 4140, and super alloys such as Inconel, Waspalloy, Invar, and Kovar. The site also lists production cutoff saws. Customers can have barstock delivered to the shop for a cut and grind in one place.

The site says the company offers pick up and drop off help for some jobs. Pick up and delivery charges may apply. The address is 4550 Runway Street, Simi Valley, CA 93063. The site asks customers to call or email quotes and questions. The phone number is (805) 583-9966.
