TWINHORN VA-500 VERTICAL MACHINING CENTER

Technical Description

This CNC vertical machining center features a **27.5" x 15.7" table** with an optional support index or rotary table, capable of handling a maximum workpiece weight of **660 lbs**. It operates on a 3-axis system (with an optional 4th axis) providing travels of **19.6" (X), 15.7" (Y), and 15.7" (Z)**, each with maximum feed rates of **197 ipm** and rapid traverses up to **630 ipm**. The spindle is vertically oriented, supporting a **CAT-40 taper** as standard with **BT-40 taper** as an option, and reaches a top speed of **8,000 RPM** configurable up to **10,000 RPM**. The spindle motor is rated at **10 HP (30-minute rating)**, delivering robust power for a wide range of milling operations. Tooling is managed through a 16-position **Automatic Tool Changer (ATC)**, enhancing productivity and precision in machining cycles. The CAT40 taper is known for its 7/24 taper angle, balancing rigidity and versatility for medium to heavy-duty milling, while BT40 offers symmetry and stability at high speeds, making both tapers suitable for various applications. The machine’s compact footprint and powerful spindle make it ideal for machining complex parts, mold components, and medium-sized aerospace or automotive components requiring tight tolerances. Its configuration supports high-precision milling with rapid motion and tool changes, suitable for workshops demanding efficiency and versatility in 3-axis CNC milling tasks, with potential to upgrade to 4-axis operations for enhanced capability. The optional rotary tables further extend its suitability for intricate rotational machining processes.
