BVG Series

This series of machine tools uses ceramic, resin bond and sintered diamond grinding wheels to grind parts of various carbon steel, alloy steel, cast iron and non-ferrous metal materials.
The worktable feed is driven by a belt, and a Siemens 1FW6 torque motor is optional; the electro-permanent magnetic chuck is a Chinese excellent brand as standard, and the German brand SAV is also available as an option.
The worktable shaft and radial guide rail pair adopt high-precision closed hydrostatic guide rails, and the runout accuracy of the worktable end face and radial direction can reach 0.003mm.
Both the columns and beams adopt large-section box-shaped cast iron structures, and the horizontal movement of the beams uses closed static pressure guide rails.
The tool grinding holder adopts a rolling grinding spindle with a spindle accuracy of 0.002mm; a double grinding tool holder is optional, and any combination of vertical and horizontal grinding tool holders is available.
The grinding stand is equipped with a B-axis, which is driven by a Siemens 1FT6 servo motor and uses circular grating feedback to achieve accurate indexing of the grinding head and vertical feed axis at any angle within +/-45 degrees.
The grinding wheel dressing device is a single-point grinding wheel dresser, optional arc grinding wheel dresser and diamond roller grinding wheel dresser.
Comprehensive cooling and protection, optional workpiece cooling refrigerator.
The CNC system adopts Siemens 828D.
Surface roughness of grinding workpiece: plane and cylindrical surface Ra0.2μm, arc surface Ra0.4μm.
