Features

  • The patented slant bed design increases the X-axis travel to 220mm and Z-axis to 500mm reducing the lathe size and stability.

  • Equipped with a 12-station servo turret, high rigidity cutting, suitable for long-axis turning, Processing of complex multi-process products such as drilling and tapping.

  • The main spindle is with C-axis positioning function, high speed, high precision, and low vibration which can make the workpiece precise. Each spindle bearing assembly was tested for dynamic balance before installation to ensure high-speed running stability.

  • MT5 Hydraulic Tailstock, automatically detects pressure and locks, providing better conditions for processing slender parts

  • Equips with 40mm ball screw rod rail and 45mm linear guideway to provide precision and low vibration tool carriage movement.

  • Equips with auto lubrication system to ensure transmission system smoothly and long-lived.

  • SYNTEC CNC system co-works with quality electrical parts providing a rapid-operation and durable use.

Application

Competent to handle the turning process with brass, bronze, aluminum, steel, stainless steel, and rigid plastic with bars diameter up to Φ71 mm or single workpieces up to Φ400mm. High Rigidity casting iron body provides the possibility of higher hardness materials and better smoothness (smaller roughness).
