The CNC strong forming grinder for inner holes is primarily composed of core components such as the bed, grinding wheel frame, work table, headstock, and tailstock. The bed serves as the fundamental support, bearing the various components and ensuring the relative positional accuracy. The grinding wheel frame is responsible for driving the high-speed rotating spindle of the grinding wheel and supports transverse feed movements; some models can adjust the angle on a horizontal plane to accommodate conical surface processing. The work table features a double-layer structure, where the upper work table can rotate horizontally for grinding long conical surfaces. The headstock is used to clamp the workpiece and facilitate rotation, while the tailstock works in conjunction with the headstock to achieve workpiece positioning. This machine tool can perform high-precision grinding of various types of workpieces, including through holes, blind holes, stepped holes, and conical holes, improving dimensional accuracy, roundness, and surface roughness. It corrects thermal deformation caused by heat treatment through micro grinding, addressing high-precision machining needs that turning and boring cannot meet.
