What Is A CNC Vertical Spindle And Rectangular Table Surface Grinder?

A CNC vertical-spindle and rectangular-table surface grinder is a machine specifically designed for grinding flat or shaped surfaces. Its characteristic feature is a vertically mounted grinding wheel spindle, with the end face of the grinding wheel directly contacting the workpiece surface during the grinding process. Compared to traditional horizontal-spindle grinders, the vertical-spindle design offers a larger contact area between the grinding wheel and the workpiece, resulting in significantly improved grinding efficiency. The worktable is generally rectangular and can stably support workpieces of various sizes. It is highly adaptable and suitable for high-precision machining of metals, cast iron, non-ferrous metals, and some non-metallic materials.

Operating Principle

The core operating principle of a CNC vertical-spindle and rectangular-table surface grinder lies in the relative motion between the workpiece and the grinding wheel. The workpiece is fixed to a rectangular worktable, which moves vertically and horizontally according to the CNC system's instructions, ensuring that the grinding wheel evenly grinds the workpiece surface. The grinding wheel spindle is mounted vertically, and the grinding wheel rotates at high speed, with the end face of the grinding wheel contacting and grinding the workpiece surface. A hydraulic system precisely feeds the grinding head vertically, ensuring that the grinding wheel can precisely adjust to the workpiece surface shape. The CNC system automatically controls the grinding wheel's rotational speed, feed rate, and grinding depth, ensuring machining accuracy and efficiency. The automatic lubrication system maintains the optimal condition of moving parts, extending equipment life.

Core Structure and Function

Main components include:

· Vertical grinding wheel spindle: The grinding wheel contacts the workpiece surface with its end face, providing a large machining area and high grinding efficiency.

· Rectangular worktable: Provides stable support for the workpiece and multi-directional motion for precision machining.
