EXTRON LH-86 HORIZONTAL MACHINING CENTER

Technical Description

The Extron LH-86 Horizontal Machining Center is a high-performance CNC machine designed for precision machining with robust capabilities. It features a travel range of 33.858 inches on the X-axis, 32.677 inches on the Y-axis, and 24.606 inches on the Z-axis, offering substantial workspace for diverse machining tasks. Powered by a 20.1 hp motor, the spindle can reach a maximum speed of 6,000 RPM, enabling high-speed cutting operations. The machine is equipped with a 24-tool arm-type tool magazine for efficient tool changes, enhancing productivity. It incorporates a rigid Meehanite cast iron structure and roller-type linear guideways across all axes to ensure high rigidity and accuracy with minimal backlash. The LH-86 uses high precision C3 class ball screws with double nuts and pre-tension design for exact positioning. Its non-counterweight balancing system on the Y-axis supports rapid yet stable movements, optimizing machining accuracy and smoothness. The machine weighs 14,550 lbs (6600 kg), reflecting its solid construction designed to withstand heavy cutting and maintain precision. The control system is CNC-based, improving automation and control flexibility. Additional design features include a table-in-table B-axis rotary table for versatile machining, a moveable console for operator convenience, and efficient chip removal via coolant nozzles around the spindle. This combination of rigidity, precision components, and smart design makes the Extron LH-86 suitable for demanding horizontal machining operations requiring both high accuracy and productivity.
