 |
| Salient Features : |
| » |
Four axes CNC internal & face grinder. |
| » |
Performs internal & face grinding sequentially in auto cycle. |
| » |
X-axis provides depth of cut during internal grinding and positioning of the wheel with respect to the bore to be ground and moves on a guide fixed at right angle to the Z-axis. |
| » |
Z-Axis is for oscillations during internal grinding & positioning of the wheel up to the bore to be ground. |
| » |
U-Axis parallel to X-axis is provided to bring the face grinding wheel to grinding position. |
| » |
Depth of cut is provided by W-axis that is at an angle of 600 in the horizontal plane with respect to Z-axis. |
| » |
Face grinding wheel is fixed on W-axis slide. |
| » |
Guideways for W-axis are fixed on U-axis slide. | |
