特征:
1.機器(固定工作臺類型)以追求超細圓柱工作的精度。
a)在超細外圓磨削中，圓度、粗糙度和尺寸控制的磨削精度一致。
2.結(jié)構(gòu)緊湊，剛性強，僅由*的機械元件組成，【研磨】【支撐】【調(diào)整】。
a) GW頭、RW頭采用高精度、高剛度定軸結(jié)構(gòu)。(滾動軸承)
3.GW機頭由2軸數(shù)控系統(tǒng)控制進給和橫移。
a)固定金剛石磨具/修整傳統(tǒng)車輪，以及旋轉(zhuǎn)金剛石自磨砂輪。
1.Ultimate machine(fixed workrest type)to pursue accuracies for extrafine cylindrical work.
a)Consistent grinding accuracies of roundness, roughness and size control in extrafine cylindrical work grinding.
2.Compact sized machine with high rigidity; composed of indispensable machine elements only, [GRIND] [SUPPORT] [ADJUST].
a)High-precision and high-stiffness Stationary Spindle structure is applied for GW head & RW head.(Rolling bearings)
3.GW head is controlled by 2-axis CNC for infeed and traverse.
a)Fixed diamond trues/dresses conventional wheels, and in addition rotary diamond self-grinds super abrasive wheels.
