| The cross and longitudinal feed employs 12mm non-contact circular proximity sensor for direction change. Its outstanding dust-proof and water-proof performance is superior to another direction change device. | The cross and longitudinal slideways are double "V" shape structure. Special angle design combined with extra wide way surfaces significantly upgrade moving stability and loading capacity. Another benefit is friction coefficient is reduced by 30% Specially designed dust guard may fully prevent dusts from entering into slideways. | |

| The spindle head is well balanced on the column. The ball screw is located at the center of column and the spindle head with weight ratio 5:4. The end face of the spindle head is precision scraped, and is precision mounted when installing the spindle. This will prevent spindle from deformation due to stress. | Y.Z-axis are transmitted through 32mm diameter, class C3 precision ball screws with double nuts. | |

| The vertical feed is driven by a 0.75kw servo motor. It drives the precision ground worm through backlash-free coupling, that drives a phosphor bronze worm gear. The worm/worm gear set drives the ball screw for vertical feed, that allows for 1um micrometric feed. | Rigid structural parts may effectively disperse all reaction force, while absorbing vibration during moving. For mirror-effect grinding on high-hardness materials, such as SKD-11 and tungsten carbide, there is great resistance of grinding. However this machine has been tested to achieve surface roughness of Ra0.015um. |
