HMT MACHINE TOOLS VMC 400M VERTICAL MACHINING CENTER

Technical Description

The HMT VMC 400M is a compact vertical machining center engineered for precision metalworking applications with a rigid cast iron construction optimized for static, dynamic, and thermal stability. This machine features a 12-tool armless automatic tool changer that enables rapid production cycles with a pallet change time of just 15 seconds. The work envelope consists of 16.54 inches of X and Z-axis travel with 15.75 inches of Y-axis travel, accommodating workpieces on a 15.75 x 25.59-inch clamping surface. The spindle operates at a maximum speed of 4,000 RPM with 4.97 hp motor capacity, delivering controlled cutting power for diverse machining operations. Positioning accuracy of ±0.005mm and repeatability of ±0.003mm ensure high-precision results consistent with modern CNC standards. The machine utilizes FANUC or Siemens CNC control systems, providing advanced programmability and operational flexibility. The Z-axis is mounted on the spindle head while X and Y axes are table-mounted, creating a conventional configuration suitable for milling, drilling, and boring operations. Direct-coupled ballscrews with feed motors and dynamically balanced cartridge-type spindle construction ensure reliable, smooth operation. The machine supports rigid tapping and high-pressure coolant systems for enhanced machining efficiency. Standard rapid rates of 20 m/min are available, with optional speeds up to 32 or 48 m/min, making it adaptable for both conventional and high-speed production requirements.
