Elevate your manufacturing capabilities by downloading the technical BQ855 Vertical Machining Center (Optical Mechanism) drawing. The “optical mechanism” (or bare machine) represents the high-precision skeletal core of the VMC, including the base, column, saddle, table, and headstock. This comprehensive drawing offers a deep dive into the structural engineering of one of the industry’s most reliable mid-sized machining platforms. Designed for versatility, the BQ855 framework is engineered to support high-speed milling, drilling, and tapping operations across various industries, from aerospace to mold making.

By utilizing this professional drawing, designers and workshop managers can analyze the casting rib structures and guide rail placements that define the machine’s rigidity and dampening characteristics. The BQ855 is renowned for its compact footprint combined with a generous work envelope, making it a favorite for shops looking to maximize floor space without sacrificing heavy-duty cutting performance. This CAD resource provides the exact coordinates for component integration, allowing for seamless customization of spindle units and tool changers to meet specific production requirements.
