Sharp LMV (CNC) VERTICAL MACHINING CENTER

Technical Description

This CNC vertical machining center features a **42" x 9" rectangular work table** capable of supporting workpieces up to **800 lbs**, designed for machining operations requiring a stable and robust platform without additional support tables or rotary tables. It operates on a **3-axis configuration (X, Y, Z)** with travels of 25" (X), 11" (Y), and an unspecified Z travel, all capable of maximum feed and rapid traverse rates of 100 inches per minute, providing balanced movement and speed for precision cutting. The vertical spindle is equipped with an **R8 taper**, optimized with a #30 taper option, rotating up to a top speed of **4500 RPM** and powered by a **3 HP motor rated for 30 minutes of continuous operation**. The R8 taper, widely used in machining centers, features a taper angle around 16.26°, providing a secure fit for tooling via drawbar clamping, ensuring rigidity and precision during machining. The spindle supports manual tooling with a single tool holder and no automatic tool changer, suitable for simple setups or manual operations. Notably, this machine lacks a U-axis for rotary movement, support rotary tables, and pallet changers, emphasizing a focus on straightforward milling tasks without automated tool-handling or additional axis complexity. Manual tool changes incur no chip time delay, enhancing efficiency for simple jobs. The overall configuration suits shops needing a reliable, manual-operated machining center with moderate table size and workpiece capacity, appropriate for prototyping and light to medium production milling.
