Commercial concrete batching plant usually is divided into two types of external factor dense bed and universal external grinder, which is composed of the main components, such as working table, bed head frame, frame, wheel rack people, a transverse feed mechanism, a hydraulic transmission system and electrical system.Commercial concrete mixing plant can grind various external column, external cone parts, and it can also grind the end surface with a tip.

The grinding wheel composed of a grinding wheel frame motor achieves the main movement through a mechanical drive rotation, the work piece of commercial concrete mixing plant is set between the headstock and tailstock, the headstock motor through mechanical transmission by dial drives the rotation of the work piece circular feed motion, wheel rack through mechanical transmission to achieve horizontal feed movement; the work piece with the workbench through hydraulic transmission to realize the longitudinal feed movement. In order to reduce the auxiliary time, the grinding wheel rack has a fast forward and backward movement. It needs to measure the size after a certain grinding. The grinding wheel rack exits quickly and then quickly adopted after the measurement. If the distance between the export and import isn’t equal, this will cause that the workpiece grinded to small or not should be grinding size. Therefore, the requirement for external grinding wheel rack rapid introduction of repetitive positioning accuracy is high.

Due to the grinding wheel can not go beyond the workpiece of new concrete batching plant, in order to avoid two ends of workpiece becoming too large because of the short time grinding, so when we are required to reverse, the worktable can stay in the reversing point for a certain period of time.When we grind the stepped shaft or the workpiece with hole, in order to prevent the end face of the grinding wheel and the workpiece end touching, the reciprocating positioning accuracy requirements of commercial concrete batching plant worktable are high.
