Features of a standard surface grinder:
● The longitudinal movement of the worktable and the lateral feed of the grinding head are hydraulically driven, and lateral feed can also be manually operated.
● Vertical feed is manual, and the grinding wheel spindle is driven by a built-in electric motor.
● The main machine is constructed of high-strength castings, seasonally aged, and manually treated, resulting in high precision and minimal thermal deformation.
