SMALTEC INTERNATIONAL MM903 VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a **7.87" x 7.87" table** capable of supporting workpieces up to **110 lbs**, optimized for precision micro machining tasks. It operates on a **3-axis system** (X, Y, Z) with travel ranges of **7.87" (X), 7.87" (Y), and 6.3" (Z)**, allowing for compact work envelope flexibility. The spindle is vertically oriented with a proprietary **Smaltec Special taper**, supporting speeds up to **50,000 RPM**, driven by a **0.30 HP motor** (rated for 30 minutes), enabling very high-speed machining applications on small components. Tooling is facilitated optionally through an **Automatic Tool Changer (ATC)** system supporting up to **32 tools**, which enhances efficiency and reduces manual setup time for complex or multi-tool processes. The machine does not include a U axis but can be optionally upgraded to 4-axis capability for additional rotational machining. The spindle’s very high RPM and compact travel limits make this center suited for precision micro-milling, drilling, or engraving on small-scale complex parts with high accuracy. Its vertical spindle configuration optimizes chip clearance and tool access, while the Smaltec taper ensures precise tool holding and repeatability. The table size and load capacity are aligned with delicate or lightweight workpieces typical in micro-engineering, medical, or fine tooling industries. Overall, this machine offers a balanced integration of high-speed spindle technology, moderate axis travel, and compact tooling capacity ideal for micro-machining applications requiring fine detail and repeatability.
