The MY7650B double disc grinder is suitable for grinding the upper and lower end faces of parts with various shapes and different materials. It is particularly applicable to workpieces that require high verticality, flatness, and parallelism, such as bearings, pistons, stamping parts, cam pieces, piston pins, rollers, and ceramic components. The grinding head movement uses V-shaped steel inlaid needle roller bearing rails, achieving grinding through integral movement rather than spindle extension, which helps improve overall machine rigidity. The spindle combines double-row short cylindrical bearings with angular contact ball bearings, allowing for a larger depth of cut and higher precision.

In terms of material selection for key components, the spindle is made of 40Cr material and undergoes forging, annealing, normalizing, quenching and tempering, high-frequency quenching, and stability treatment. The guide rails are made of Gr15 material, the inlet and outlet plates are made of 65Mn material, and the feed mechanism uses a high-precision ball screw assembly. The spindle has no spline and does not perform telescopic movement. Combined with special machining processes that ensure concentricity of the bearing holes in the spindle box, mechanical friction is relatively low, resulting in higher output power for the same input power.

The dresser has an integral structure and belongs to an independent dressing system, with a single dressing arm dressing both grinding wheels simultaneously, providing good stability and dressing accuracy. The swing arm performs both coarse and fine dressing in one process, and supports automatic dressing and compensation. The grinding feed can achieve hydraulic inching and automatic compensation. The grinding wheel protective cover can be raised and lowered automatically and includes wheel limit protection. Additionally, the machine is equipped with interlock safety devices between the cover and grinding head rotation, as well as between dressing and grinding, enhancing the degree of automation and operational safety.

Both the feeding and discharging guides adopt a sleeve-type sliding structure. The feeding and discharging plates are adjusted using internal bolts that can be tightened through external screws, allowing adjustment in both horizontal and vertical directions with relatively simple operation. This design helps address common issues such as difficult adjustment, low efficiency, large dimensional variation, and inconsistent precision.
