FEATURES
High rigidity casting components may effectively disperse all reaction force, while absorbing vibration during movement. 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 Ra 0.015 um
The cross and longitudinal feed employs 12mm non-contact circular proximity sensor for directional change. Its outstanding dust-proof and water-proof performance is superior to another device

Y, Z axes are transmitted through 32mm diameter, class C3 precision ball screws with double nuts.
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 stressThe 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.
