B.C. Instruments

BC Instruments is a precision machine shop that provides high quality, CNC machining and manufacturing services to clients in the nuclear, aerospace, medical, electronic, oil & gas and injection molding industries.

Established in 1971, BC Instruments (BCI) is a privately owned Canadian Company with plants located 45 minutes north of Toronto, in Schomberg, and Orillia, Ontario. Presently, we employ 130 employees in manufacturing facilities totaling 58,000sq.ft. Annual sales for fiscal 2012 totaled $24 million.

Utilizing modern state of the art CNC equipment, our skilled employees specialize in the manufacture of components and assemblies requiring tolerances as close as 25 microns. We also have the capability and experience to work with customers through the research and development stage of new projects. We make use of a number of machines that utilize high speed spindles, high pressure coolant and constant chip evacuation to machine components at high metal removal rates. We have in-house capacity to machine parts requiring hard milling / turning, honing, laser engraving, single and dual face lapping.

In addition to conventional materials, we are experienced in working with such exotic materials as Hy-Mu 80, Titanium, Inconel 718, A-286, Monel, Haynes Alloy 41 (Rene 41), Metal Matrix Composites (MMC) and various grades of ceramic.

Of special note is our Engineered Materials Machining Section’s (EMMS) use of Ultrasonic Technology to machine near diamond hardness materials such as alumina & zirconia oxides, glass, silicon nitrate, carbide and even man made ruby. The DMS 35 Ultrasonic machine built by Sauer in Germany makes efficient machining of advanced materials possible. With the aid of an ultrasonic spindle, the vibration of the high-tech spindle is transferred to a hollow diamond tool. The tool vibrates at a rate of 20,000 cycles per second, and thus removes miniscule particles from the surface of the work piece. EMMS operates out of a 4,000 square foot facility in Barrie.

We have the ability to translate most known formats of CAD data, including Step AP203/AP214, DXF and IGES for manufacturing customer parts. In addition we can support many native formats such as Catia V5, Pro Engineer and Solid Edge.

BCI is associated with Aerospace Metal Finishing (AMF), located next door to BCI, which provides surface finishing services such as anodizing, electroplating, prime and topcoat. Staveley Services Canada Inc. is stationed on site at AMF to provide non-destructive inspection services such as magnetic particle and fluorescent penetrant inspection.

In 2004 BCI opened BC Instruments India Private Limited located in Gujarat State,India. In 2012 BCI India has manufacturing facilities of 22,000 sq. ft. and 70 employees.
