Condition: new, Year of construction: 2026, functionality: fully functional, The basic components of the grinding machine include: base, slides, column with grinding wheel spindle, rotary table, and control cabinet. The table is driven by a mechanical transmission and a gearbox-frequency converter unit, and performs a rotary motion. The rotary speed of the table is adjusted using a potentiometer on the machine's control panel. In manual operation, the machine will have the ability to perform pulsed rotary movement of the table, controlled from the operator's panel. The transverse feed is performed by the column and spindle moving along the rolling guides of the base. This movement is realized using a ball screw with a belt drive and an asynchronous motor controlled by a frequency inverter. The vertical feed is performed by the spindle moving along the sliding guides of the column. A ball screw is used to drive the vertical feed. The continuous feed of the column is stepless. These values are set from the control panel. The machine will be equipped with a direct digital readout on the vertical axis with a resolution of 0.001 mm. An electronic handwheel for vertical axis feed during manual operation and an operator panel (programmable display) will be placed on the operator's panel. The grinding machine will have smooth adjustment of the grinding wheel spindle speed and the table speed. The machine will be able to operate in an automatic cycle with the possibility of programming the number of sparking passes and other parameters necessary for grinding in an automatic cycle. Safe operation of the grinding machine is ensured by a semi-enclosed cabin and all electrical and mechanical safeguards in accordance with CE standards. 1 Table working surface Ø800 mm 2 Maximum distance between the table surface and the spindle axis during manual spindle feed 350 mm 3 Minimum distance between the table surface and the spindle axis 125 mm 4 Maximum weight of the workpiece 2500 N 5 Range of steplessly adjustable table speed 2-100 m/min 6 Maximum horizontal column feed 450 mm 7 Range of steplessly adjustable column feed speed 0.2 – 3 m/min 8 Grinding wheel feed per: 1 encoder unit 0.001 mm 9 Minimum automatic grinding wheel feed 0.001 mm 10 Maximum automatic grinding wheel feed 0.040 mm 11 Speed of accelerated grinding wheel feed 1 m/min 12 Grinding wheel spindle speed 1000 – 2500 RPM 13 Diameter of new grinding wheel 400 mm 14 Diameter of worn grinding wheel 250 mm 15 Bore for mounting the grinding wheel 127 mm 16 Width of grinding wheel nominal / maximum 50 mm Rsdpfx Aozfyvyshcecf
