This listing is for a Коломна 5А342 horizontal gear hobbing machine manufactured in 1985. The machine is designed for machining large cylindrical gears with a maximum wheel diameter of up to 2000 mm. It supports a wide range of gear modules, including hobbing cutters with modules of 20 mm, disk cutters of 25 mm, and finger cutters of 30 mm. The machine can handle gears with tooth line angles up to ±45 degrees.
The rotary table diameter is 1800 mm, and it can accommodate workpieces weighing up to 20,000 kg, including fastening elements. The maximum diameter for installed hobbing cutters is 300 mm, with a maximum cutter length of 500 mm. The machine operates within a spindle speed range of 8 to 125 rpm and can cut gears with 10 to 1800 teeth.
Feed rates vary depending on the operation, with axial feeds during running-in ranging from 0.02 to 510 mm/min and radial feeds from 0.013 to 328 mm/min. The spindle delivers a torque of at least 2.5 kN·m. The main drive power is rated at a minimum of 20 kW. The machine requires a three-phase alternating current power supply with a nominal frequency of 50 Hz and voltage of 380 V.
The overall dimensions of the machine are approximately 6600 mm in length, 2300 mm in width, and 3300 mm in height, with a total weight of around 32,000 kg.
The machine shows visible signs of age and extensive use, including rust and wear on the base and other components. The rotary table and spindle assembly are present, with metal chips observed on the work surface indicating prior machining activity. The control panel features multiple buttons, switches, and gauges, although it exhibits wear, dirt, and paint peeling. The internal housing and gear hob mounted on the spindle show signs of heavy use with oil stains. The hydraulic or lubrication system includes visible pipes, valves, and gears with accumulated grime. The electric motor and internal gears are installed securely but show wear consistent with long-term operation. Guide rails on the vertical column appear worn but structurally sound.
This machine is offered without testing due to a power outage at the plant, and the price is based on the machine's foundation. Prospective buyers are encouraged to consider all cooperation options.
