The horizontal grinding head adopts high-precision flange type spindle design. With three pairs of super-precision angular contact bearings (made in Japan/Germany), using high-temperature resistant high-grade lubricating grease, completely sealed, no need for additional maintenance. Therefore, it can maintain high quality characteristics such as low noise, high precision and low temperature during grinding. The grinding machine is equipped with a safety type grinding wheel with buffer protection device. The wheel adopts reasonable structural transformation, so that the safety of the operator is guaranteed.The worktable adopts the fully supported double V self-positioning type hard rail design, the base rail is processed by high frequency, HRC55±, the worktable rail is affixed with PTFE rail tape, to ensure the good smoothness and guidance of the table motion rail.
