What is the operating principle of gantry grinder?

The bed of the double column planner surface grinder adopts double V-shaped guide rails, and the guide surface of the worktable is covered with wear-resistant polytetrafluoroethylene. The trailer moves laterally along the crossbeam guide rail, and the lateral feed is driven by a DC motor. Horizontal feed is controlled by CNC feed. The longitudinal movement of the workbench is driven by a blade oil pump. It has stepless speed regulation and adopts an open hydraulic system. The hydraulic oil and guide rail lubrication have oil temperature control devices. The grinding head can move up and down along the vertical guide rail of the drag board. Vertical feed has two modes: fast and automatic, and manual feed. Using CNC feed, easy to operate. The grinding head spindle adopts a sleeve type structure and a connected transmission, and the spindle bearing is a high-precision radial thrust ball bearing.

In addition to the aforementioned gantry surface grinders, there are also precision surface double column planner surface grinder. The precision flat double column planner surface grinder is mainly used to grind the flat surface of large short and wide workpieces around the grinding wheel. During grinding, the workpiece can be directly fixed on the worktable or electromagnetic suction cup. The fine gantry surface grinder adopts a gantry layout, consisting of a closed rigid frame structure composed of a bed body, double columns, and crossbeams. The bed adopts double V-shaped guide rails, and the guide surface of the workbench is covered with wear-resistant polytetrafluoroethylene.

The horizontal and vertical grinding necks of the precision flat double column planner surface grinder share a set of sliding pillows to add multifunctional uses, with a simple structure and easy operation. High precision dynamic and static pressure spindle is selected, which has high precision, long service life, low noise, and low failure rate. It is also equipped with a belt transmission force support seat to prevent the spindle from being affected by force due to the belt being too tight. The horizontal grinding neck spindle and transmission motor adopt an embedded structure, and then the thickness of the sliding pillow is added to improve the strength during vigorous grinding. The vertical grinding neck comes with a movable slider, which can rotate the viewpoint and grind various inclined surfaces over a large area. It is also convenient to adjust various inclined grinding wheels without the need for a dedicated grinding wheel conditioner.
