Manufactured in 1984, the machine is intended for industrial applications requiring reliable performance, versatility, and repeatable accuracy. The machine is suitable for workpieces with a maximum length of 1000 mm and a maximum diameter of 500 mm. The maximum machining (spline/thread) length is 880 mm, and the machine supports gear cutting up to module 8, covering a wide range of thread and gear machining tasks. Helix and thread angles up to 30° can be machined, allowing flexible use in mechanical engineering and transmission manufacturing. The milling and hobbing spindle features a 90 mm spindle bore and supports cutting tools with a maximum hob diameter of 160 mm and a maximum hob length of 200 mm. The spindle operates in a speed range of 25 to 400 rpm, providing suitable cutting conditions for different materials and tool diameters. The main drive motor offers multiple power and speed stages (5 / 6.3 / 10 kW at 750 / 1000 / 1500 rpm). The machine is equipped with stepless longitudinal and radial feeds, with longitudinal feed rates from 2 to 100 mm/min and radial feed rates from 2 to 50 mm/min, enabling precise control during machining operations. The milling head is horizontal and swivelling, and the machine allows accurate synchronization for thread milling and gear hobbing operations. With overall dimensions of approximately 3100 × 2270 × 2100 mm (up to 3540 × 2515 × 2100 mm with auxiliary equipment) and a total weight of about 7890–8500 kg, the 5A352ПФ2 features a rigid, heavy-duty construction that ensures excellent stability and vibration damping.
