Vertical Rotary Table Surface Grinder Selection Comparison for Workpieces with Different Diameters

Grinding requirements vary for workpieces of different diameters, and properly matching the rotary table size is the key to machine selection. Shandong Linmo’s vertical spindle rotary table surface grinders cover a full range of table diameters from 400mm to 2500mm, capable of meeting the full spectrum of machining demands ranging from small precision parts to large workpieces.

For workpieces around 300mm in diameter, the MGGP7440 vertical spindle rotary table grinder features a 400mm table diameter with a maximum grindable workpiece size of 400×200mm, serving as a cost-effective option for small-batch precision machining. For medium-sized workpieces with diameters of 600–800mm, the MGGP7480 model is recommended. It has an 800mm table diameter and a grindable size of 800×300mm, suitable for mass production of automotive components, bearing rings and other products.

For large workpieces over 1000mm in diameter, Shandong Linmo offers large vertical spindle rotary table surface grinder models from MGGP74100 to MGGP74250, with a maximum grindable workpiece size of 2500×600mm. One important note for machine selection: the rotary table diameter is not equivalent to the maximum grindable workpiece diameter; the actual grindable workpiece dimension is slightly smaller than the table diameter. The electromagnetic worktable of Shandong Linmo rotary table grinders delivers an adjustable smooth magnetic force ranging from 80 to 120 N/cm² with stable precision, ensuring reliable clamping and steady machining for workpieces of all sizes.
