Product Description
FEATURES:

Advanced construction, optimized design:
Inclined guide-ways, fix transom construction, integer column and increased bed create high rigidity and high stability.
High capability linear guides motion assemblies:
Preload THK roller guides and pre-tensibility Roxroth ball screw assemblies create super motion accuracy, super accuracy and super stability in two linear servo motor assemblies. (X axes and Z axes)
Hydrodynamic & Hydrostatic pressure spindle, rotating accuracy in up to 1μ :
Hydrodynamic & Hydrostatic pressure wheel spindle, spindle motor drive wheel spindle by multi-wedge typed tape, so wheel motion is smooth and has good rigidity. The work-piece ground roughness is one degree higher than common spindle.
Super capability work table:
Work table (work spindle) aligned by precise bearing, supported by unloading flat guide, spindle motor drive work table by tooth-typed tape, so this machine has high motion accuracy, high rigidity and smooth movements.
CNC control, all purposes and high efficiency:
This machine can carry out any two or three axis combination movements in X, Z, B(optional) controlled axis. Grinding frame can be semi-rotate, so this machine have all purpose, high automation degree, precision and high efficiency.

Work piece vertical chucked by electrical magnetic:
Work table can be configured a acetabulum (optional). Work piece can be chucked vertically by acetabulum to eliminate distort owed to work piece dead weight and chucking. So it can be grinding all the surfaces except absorb surface, such as outer, inner, shoulder, end face of work piece. The work piece finished grinding has high geometry accuracy.

High rigid, High stability, High power, Perfectly combined with CNC, precision, all-purpose and high efficiency

Overall arrangement in reason, Advanced construction, Finite Element Analysis optimized design.

Work-piece vertical chucked by electrical magnetic, minimum distort in chuck, grind more surfaces in one chuck. Ground accuracy and efficiency are higher than a horizontal grinder. The best choice to grind large precision bearings and flat precision ring type work-pieces for grinder in product line.

Application range:

This machine has features such as Big power, high accuracy, supper rigidity, CNC control and high efficiency. It is suitable to rough grinding semi-finish grinding and finish grinding in small batch, more variety production line.

Is is special suitable to grind ID and OD of bearings`inner and outer rings and end surface. It is also suitable to rough/semi/finish grind many kind of arc path in shoulder surface, end surface and inner/outer round surfaces.

It is suitable to grind ring type, tray type, cylinder type work-pieces with complex sections combined line, arc, anycurvilineal. It can complete all the surface such as inner/outer round surfaces, end surfaces and shoulder surfaces in one chuck.

Especially fit for the grinding process of the channel, inner-outer and end surface of pitch-change bearing and yaw bearing of the wind-electricity system.
