Sharp KMA-3 VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a **59" x 23.63" table** capable of supporting workpieces up to **2,800 lbs**, suitable for heavy-duty machining tasks. The spindle is vertically oriented with a #50 taper, providing a **top speed of 1,500 RPM** powered by a robust **20 HP motor** rated for 30 minutes, delivering ample torque for milling operations. The machine operates over **three axes (X, Y, Z)** with travels of **59.0", 23.63", and 30"** respectively, and offers a consistent feed rate of 39 IPM with rapid traverse speeds up to 130 IPM, optimizing productivity for larger parts. Tooling is manual with a single tool capacity and instantaneous tool change chip time, indicating suitability for operations not requiring frequent or automated tool changes. No pallet changer or U axis is provided, focusing the machine on straightforward vertical milling applications with rigid stability. This configuration is ideal for precision machining of large, heavy components within a moderate speed range, emphasizing rigidity and workpiece capacity over high spindle speeds or automated tooling. The table size and weight capacity cater to substantial parts, while the spindle power ensures reliable cutting performance. The 3-axis system supports precise contouring and milling work within the specified travel limits. Overall, this vertical machining center combines a heavy-duty tabletop, powerful spindle, and standard 3-axis motion with manual tooling, suited for machining operations demanding robustness and capacity over high-speed automation.
