The MW7675B CNC reciprocating double disc grinding machine is mainly used for grinding both end faces of large bearing inner and outer rings, as well as other large-sized workpieces. The machine consists of the following main components: the bed, left and right grinding heads, left and right slides, left and right feed compensation mechanisms, the front bed reciprocating mechanism, an independent grinding wheel dressing mechanism, an electrical control system, a hydraulic system, and a dedicated workpiece clamping mechanism. The grinding wheel feed speed, dressing speed, and dressing frequency can be preset or modified via a program. When the continuous grinding count reaches a set value, the feeding mechanism first stops feeding; after the workpiece in the grinding area is discharged, the left and right grinding heads automatically separate to the dressing position and begin automatic dressing. Once dressing is complete, the grinding heads automatically return to the grinding position, and the feeding mechanism restarts, completing an automatic grinding cycle.

The grinding wheel feed uses a high-precision ball screw, and the guide rails are V-shaped steel inlaid needle roller rails. The spindle, as the core component, is made of 40Cr material and undergoes forging, annealing, normalizing, tempering, quenching, and qualitative treatment. The overall layout is relatively compact, the design is reasonably sound, rigidity is good, and service life is relatively long. The grinding head moves as a whole to perform grinding rather than using spindle extension, which helps improve rigidity; the spindle is preloaded with a constant force, allowing for a larger depth of cut and higher precision. The dresser has an integral structure, using one dressing arm to dress both grinding wheels simultaneously, offering good stability and dressing accuracy, and supporting automatic dressing and compensation. The machine bed is heat-insulated, helping to maintain stable accuracy during long periods of continuous operation. When the grinding wheel wears down to the limit size, the feeding mechanism automatically stops feeding and triggers an audible and visual alarm. The grinding wheel protective cover can be raised and lowered automatically, and is equipped with interlock safety devices between cover movement and grinding head rotation, as well as between dressing and grinding, which enhances operational safety to some extent. Additionally, a frequency converter can be optionally added for stepless speed regulation of the grinding head to achieve differential grinding. A servo motor can also be added to enable servo-controlled feed and compensation.
