Product Description

 CNC cylindrical grinding machine

 

This series of machine tool is a two-axis linkage CNC numerical control cylindrical grinder. SIEMENS, FANUC or other numerical control systems are selected. The movement of the worktable and the wheel carrier is completed by the AC servo motors on the Z-axis and X-axis to drive the ball screw. X, Z axis linkage realizes linear and circular interpolation, and completes the grinding of inclined surface and circular arc. Through reasonable programming, the machine can complete the grinding of single or combined surfaces such as cylindrical, conical, and shoulders of various small and medium-sized parts. The grinding wheel can be shaped and trimmed to achieve the shape grinding. In addition to satisfying the external cylindrical surface grinding of traditional industries such as automobiles, motorcycles,compressors, automotive gearboxes, oil pump nozzles, and valve stems, it is also suitable for rollers, ceramics, and semiconductors such as stereo printing Grinding of outer cylindrical surfaces in emerging industries

The table (Z-axis) guide adopts open unloading hydrostatic guide structure, and the transverse feed (X-axis) adopts Swiss N/O linear guide structure. It adopts high precision roller screw drive, zero clearance, low speed and no creep.

The spindle of the grinding whel adopts large taper, four oil wedge, automatic adjustable hydro-dynamic pressure bearing, the workhead adopts hydro-static spindle center-fixed grinding structure, the tailstock adopts dense bead sleeve or linear bearing structure, the whole machine has strong rigidity and high precision

The machine bed adopts double-layer structure (finite element analysis), the casting with special ratio is cast in one piece, and the combined surface is manually precision scraped, thus the thermal deformation is stable and the accuracy is stable for a long time. Among them, GDK-M series adopts mineral bed structure, no deformation, and the accuracy is more durable and stable.
