Expand Machinery GMV-2 VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a work table measuring 49 inches in length by 9 inches in width, capable of supporting workpieces weighing up to 200 pounds. It utilizes a single vertical spindle with an R8 taper, allowing for precision tool mounting; an optional #30 taper is also available. The spindle operates at a maximum speed of 4,200 RPM, with an optional upgrade to 6,000 RPM, powered by a 3.0 HP motor rated for 30-minute duty cycles. Tooling is manual with one tool carrier, supporting traditional operation. The machine offers three axes of movement—X, Y, and Z—with travels of 36.0 inches, 12.0 inches, and 12.0 inches respectively, providing versatile machining capability within a moderate workspace. Rapid traverse speeds and maximum feed rates are unspecified, indicating that feed adjustments may be manual or depend on external controls. The R8 taper spindle, designed originally by Bridgeport, features a taper angle approximately 16.26 degrees, providing secure tool holding via drawbar retention and is commonly employed in knee mills for its balance of rigidity and ease of tool changes. The spindle’s power and speed enable it to handle a range of milling, drilling, and cutting tasks for moderate-sized workpieces. The work table size and travel dimensions suggest suitability for precision parts machining with moderate footprint requirements. This configuration is tailored for manual operation with moderate horsepower and spindle speeds, suitable for metalworking shops requiring a reliable CNC or manual vertical milling solution for small to medium parts.
