YCM NTV 158 VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a robust work table measuring 64.960 inches in length and 29.920 inches in width, capable of supporting workpieces up to 4,400 lbs. The table support options include auxiliary index and rotary tables for enhanced flexibility. The spindle is vertically oriented with a standard BBT40 taper and an optional upgrade to BBT50, enabling tooling stability and superior concentricity through dual-contact design. It operates at a top speed of 10,000 RPM with an optional upgrade to 12,000 RPM, powered by a 30 HP motor rated for 30 minutes, upgradeable to 33 HP for enhanced heavy-duty cutting performance. The machine utilizes a 24-tool automatic tool changer (ATC), expandable to 48 tools, achieving rapid tool change times of 1.90 seconds with a chip-to-chip time of 3.40 seconds, optimizing productivity. It supports three axes standard with an optional fourth axis, with no provision for a U-axis. Axes travels are 60.240 inches (X), 29.920 inches (Y), and 27.560 inches (Z) respectively, all capable of a maximum feed rate of 394 inches per minute and rapid traverse speeds up to 1,179 inches per minute, ensuring efficient material removal and high throughput. Optional pallet changers and rotary tables enhance automation and multi-fixture capabilities. The combination of the dual-contact BBT spindle taper and high-rigidity structure ensures precision, stability, and extended tool life in demanding machining environments.
