EXTRON LH-119G HORIZONTAL MACHINING CENTER

Technical Description

The Extron LH-119G Horizontal Machining Center is a robust CNC machine designed for heavy-duty precision machining. It features substantial axis travels of 43.3 inches on X, 32.7 inches on Y, and 35.4 inches on Z, enabling versatile workpiece handling. Powered by a 25 hp motor, the machine operates at a maximum spindle speed of 4,500 RPM, suitable for diverse milling and cutting tasks. Its rigid Meehanite cast iron construction ensures high structural stability and vibration resistance, essential for precise machining results. The LH-119G is equipped with a high-torque gear-head spindle and uses high-precision C3 class ball screws with double nuts and pre-tension to minimize backlash and enhance accuracy. Its linear guideways on all axes, including a rolling type design on the Y-axis with multiple roller blocks, further improve positioning precision and reliability. The tool magazine holds 24 tools using an arm-type automatic tool changer, facilitating efficient tool management and reducing downtime. The machine incorporates a large rotary B-axis table, sized at 740 x 700 mm, to accommodate heavy loading and complex machining operations. A non-counterweight balancing system on the Y-axis optimizes rapid movements and smooth motion. Weighing approximately 19,400 lbs (8,800 kg), this machining center integrates a movable control console for operator convenience. Its engineering is suited for high-speed, high-torque applications with superior chip disposal and is geared toward industries requiring heavy cutting and complex parts production with high precision and repeatability.
