Cylindrical grinding machine OGC-1012

workpiecehorizontalCNC

INTRODUCTION
The OGC-1012 is a CNC cylindrical (external) grinder designed for precision external grinding of shafts and cylindrical components. Both X and Z axes are driven by precision ball screws and servo motors and the machine is controlled by an integrated CNC system with a graphical (GUI) operator interface to simplify process programming and dressing operations.

▎CAPACITY
Swing Over Table: Ø270 mm
Distance Between Centers: 300 mm
Max. Grinding Diameter: Ø250 mm
Max. Grinding Length: 300 mm
Grinding Wheel: Ø355 x 38~50 x Ø127 mm


▶ MACHINE FEATURES
USER-FRIENDLY OPERATION SYSTEM
▪ Built-in CNC control with GUI for graphical process editing and dressing—no complex G/M code programming required.

RIGID MACHINE BASE
▪ Heavy-duty structure engineered for improved rigidity and stability during grinding operations.

HYDROSTATIC LUBRICATION SYSTEM
▪ Automatic hydrostatic lubrication on table and wheelhead slideways for smooth feed and consistent precision.

WHEELHEAD CONSTRUCTION
▪ Wheel spindle made from alloy steel SNCM-220 with heat treatments and precision grinding
▪ Surface hardness above HRC62 for long-term concentricity and wear resistance.

WORKHEAD & TAILSTOCK
▪ Precision bearings and servo-driven workhead with stepless speed control
▪ Fixed spindle for accuracy
▪ Tailstock with oil-bath lubrication and oil level sight.

DIAMOND TOOL HOLDER (slider mounted type)
▪ Dressing device mounted on Z-axis slide to reduce dressing-related errors
▪ Multiple dressing devices available.
