The DANOBAT HG 91-3000-B8 is a robust 4-axis cylindrical grinding machine manufactured in 2007. It is equipped with a CNC control system from SIEMENS, model 840D, ensuring precise and programmable operation. This machine offers a maximum grinding length of 3,000 mm and can accommodate workpieces with a maximum grinding diameter of 850 mm. It supports heavy workpieces weighing up to 5,000 kg when mounted between centers.
The machine features a swivel wheelhead with an angle range from -30° to +180°, allowing versatile grinding positions. The grinding wheel measures Ø760 x 80(100) x Ø304.8 mm and operates at a cutting speed of 45 m/s, powered by a 22 kW spindle motor. The spindle speed range for the workhead is 10 to 120 rpm, with a Morse 6 center cone.
The X-axis (transversal carriage) provides an effective travel of 650 mm, with programmable speeds ranging from 0.01 to 6,000 mm/min and a minimum increment of 0.001 mm in diameter. It has a motor torque of 22 N·m. The Z-axis (longitudinal carriage) offers similar speed programmability and a motor torque of 42 N·m.
Additional features include a hydraulic tailstock with a maximum taper correction of ±0.20 mm and center travel of 100 mm, using an ASA 4 center cone. Dressers are positioned on both the workhead and tailstock for wheel maintenance.
The machine weighs 29,000 kg and has a center height from spindle to table of 1,604 mm. It includes a control panel with multiple buttons and a display screen mounted on the right side for operator convenience. The grinding spindle and workpiece holding area are enclosed within the machine, and a grated platform with safety railing provides safe operator access. The machine appears clean and well-maintained with no visible damage, indicating good preservation of its condition.
This DANOBAT HG 91-3000-B8 is a powerful and versatile grinding machine suitable for heavy-duty cylindrical grinding tasks. Interested buyers are encouraged to contact for further information.
