Like the TaiyoKoki machine, the vertical grinding machine places the guides of these axes above the grinding action point. Grinding dust does not fall on these moving surfaces. This reduces wear and extends the life of the machine while maintaining its accuracy.
application
From this discussion, we can clearly see that workpieces with relatively large diameters and short lengths benefit the most from vertical grinding. Many automotive parts have geometric features suitable for vertical grinding. Machining automotive parts is the most common application for vertical grinding machines. A typical non-automotive application is the bushing of a vertical grinding machine. These workpieces can be efficiently processed on large vertical grinding machines.
The application also shows what type of vertical grinding machine is most suitable. This type of grinding spindle works best when it is locked in the upright position when the best results for inner diameter grinding are critical. In addition to inner diameter grinding, this configuration is also suitable for surface grinding. According to the manufacturer, this is the most common form of vertical grinding machines.
When the best results for OD grinding are critical, the grinding spindle is fixed at a 30° angle and works best with a slanted grinding wheel. Surface grinding is also possible on these models.
Grinding spindles are most flexible on the hexagonal tool holder and are best suited for best results in single-step installations. These models automatically switch the grinding angle for internal diameter, outer diameter and surface grinding on the same machine. Typically, the turret is equipped with an inner diameter grinding head and an outer diameter grinding head. Another option is to have two inner diameter grinding heads or two inner diameter grinding heads plus one outer diameter grinding head on the hexagonal tool holder.
For some models where the grinding spindle is mounted vertically, automatic tool change is possible. The spindle moves in the X and Z directions to approach the descent and pick-up stations, which are protected by an automatically opened and closed door. This system allows the replacement of grinding tools and enhances the flexibility and productivity of vertical grinding.
