M7640 Through-Type Double-Sided Grinding Machine

Machine Tool Application:

This machine tool is primarily used for the grinding of two parallel ends of small and medium-sized bearing inner and outer rings, oil pump rotors, uniform connecting rods, retaining rings, piston rings, valve seats, valve pieces, gears and sleeves, graphite blocks, flanges, copper and aluminum precision plates, and can also be used for the grinding of two parallel ends of other circular, non-standard metal and non-metal workpieces.

Machine Tool Structural Features:

1. The bed frame and workbench are made of cast iron, treated for aging, and boast excellent overall seismic performance.

2. The machine tool features a horizontal layout, with the two grinding wheel heads' in-and-out guide tracks using manually scraped ∧-shaped rigid guide rails, fitted with guide track belts. It boasts rigidity, high repeat positioning accuracy, long service life, and easy maintenance.

3. Machining machines utilize through-type and belt roller friction feeding methods. Non-standard parts can be fed using chain drive or non-standard belt feeding methods based on the geometrical dimensions of the workpiece, implementing a continuous grinding process. The feeding method and form can be determined according to the geometrical dimensions and precision of the user's workpiece, and an automatic feeding lifting device can be used.

4. Feeding and reversing of the machine tool abrasive wheel, as well as automatic dressing, are controlled by electrical and hydraulic systems. Both abrasive wheels can be independently dressed and can perform concave-convex corrections on the wheel.
