▶ MACHINE FEATURE

HIGH PERFORMANCE GRAPHICAL USER INTERFACE
▪ Graphical dialogue operation interface for simplified, safe programming and operation.
▪ Numeric programming settings can automatically execute grinding cycles, dressing cycles and compensations.
▪ Single-key memory for mechanical origin, grinding, dressing and compensation coordinates.
▪ Multiple grinding and dressing methods selectable to match workpiece requirements.

RIGID MACHINE BASE
▪ Reinforced machine structure with thicker slideway and 1V-1 flat guideway design; lubrication system designed on static-pressure principle for improved precision and stability.

HYDROSTATIC LUBRICATION SYSTEM
▪ Advanced automatic hydrostatic lubrication for table and wheelhead slideways to improve lubrication performance, feed smoothness and feed-rate precision.

WHEELHEAD CONSTRUCTION
▪ The grinding wheel spindle is manufactured from high-grade SNCM-220 alloy steel with normalization, quenching, tempering, carburizing and cryogenic treatments, followed by precision grinding and mirror finish; surface hardness above HRC62 for durability and accuracy.

WORKHEAD AND TAILSTOCK
▪ Work spindle uses precision bearings for stability.
▪ Workhead driven by servo motor with continuous variable speed.
▪ Fixed-type work spindle for improved accuracy and stability.
▪ Tailstock with oil-bath lubrication and oil level indicator to maintain consistent precision.

DIAMOND TOOL HOLDER
▪ Tailstock-mounted diamond tool holder; multiple dressing devices available to suit component requirements.
