Product Description

Precision CNC Series Cylindrical Grinding Machine
This series of machine tools is a two-axis linkage CNC high-precision CNC cylindrical grinder, using SIMENS, FANUC or other numerical control systems. 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 the precision grinding of the outer cylindrical surface of traditional industries such as automobiles, motorcycles, compressors, automotive gearboxes, oil pump nozzles, and valve stems, the product is also suitable for rubber rollers such as stereo printing, ceramics, Precision grinding of outer cylindrical surfaces in emerging industries such as semiconductors.

MMKSTRUCTURAL FEATURES
 
The spindle of the grinding wheel adopts the large taper four-oil wedge bearing to automatically adjust the gap dynamicpressure, which has higher rigidity and precision of the grinding wheel.
Table (Z axis) drive and horizontal feed (X axis) drive drive adopts THK ball screw servo direct drive structure,Table (z- axis) guide rail adopts open unloading hydrostatic guide rail structure, good rigidity, motion balance, low friction coefficient, lowspeed and no creep.The transverse-feed (X-axis) guide rail adopts Swiss linear guide rail and applies pre-tightening force to meet the requirements of high rigidity, low friction, no clearance and good dynamic response for precision grinding.
The workhead adopts static spindle top grinding structure with good rigidity, suitable for precision grinding.
Tailstock sleeve adopts linear bearing structure, no gap feeding, good rigidity, and can realize hydraulic braking and manualdual mode control.
The bed adopts double-layer structure (finite element analysis), special ratio cast iron casting, manual scraping and grinding of guide rail surface, good dynamic/static rigidity. stable thermal deformation.

STRUCTURAL FEATURES
The layout of the machine is the movable table t-type layout, and the leftright movement of the table (z-axis) and the transverse movement of the wheelhead(X- axis) are driven by the servo motor and ball screw.
Lubrication by intermittent lubrication pump for centralized lubrication ,The workhead is a dead center structure, and the tailstock workpiece is manually jacked and released. The adjustment of jacking force can be realized by adjusting the com-pression quantity of the spring. The wheelhead is a dynamic bearing structure of tile, which has good grinding rigidity and high precision.
Workpiece grinding can realize CNC programmed automatic grinding, which can meet the requirements of automatic grinding of most small and medium-sized parts. It can well replace the traditional manual cylindrical grinder, and reduce the requirement of machine tools for personnel operation level. One worker can operate multiple machine tools at thesame time.
