2. Select Faceplate Diameter
Faceplate Diameter Choices | ||||
Workpiece Diameter: Must be within the rotary table diameter |
|
Ø125 | Ø170 | Ø210 |
Workpiece Weight: Must be within the chosen table load specifications | ||||
Workpiece Positioning: The value of the (F x L) should be within the torque force | Ø255 | Ø320 | Ø400 | |
When the Eccentric Load is Applied: The workpiece inertia should be within the allowable value | ||||
Workpiece of Larger Diameter, but Lighter Weight: The workpiece must not interface with the machine tool | Ø500 | Ø630 | Ø800 |
3. Determine Servo System
Determine Servo System | ||
---|---|---|
Additional Axis (the 4th or 5th axis) Installed in the Machine Tool Control |
1 | When simultaneous machining with the X / Y / Z axis is required. |
2 | Rotary table programming is input at the machine tool control. | |
Independent Controller (M-Signal) Used | 1 | When the compatible servo amplifier for the 4th or 5th axis is not available. |
2 | Rotary Table programming should be input directly into the independent control. | |
|
4. Determine Table Positioning
Determine Table Positioning | ||
---|---|---|
Vertical | Horizontal | Both |

Ensure that there is no interference among the rotary table, workpiece, and machine tool. |
||||
Weight | 1 | Check that the control weight of the workpiece and rotary table is within the allowable load of the machine | ||
X-Axis | 2 | Check the workpiece length to ensure it fits on the machine table. | ||
X-Axis | 3 | Check if the maximum allowed protrusion of the base plate is less than 10mm at both ends. | ||
Y-Axis | 4 | Check to ensure no interference with the column. | ||
Y-Axis | 5 | Check to ensure there is no interference with the splash guard. | ||
Z-Axis | 6 | Check if the effective stroke on the Z-axis is acceptable. | ||
Z-Axis |
7 | Check that there is no interference with the ATC. | ||
a. | Distance between the spindle nose and the working table | |||
b. | Stroke for the tool changer | |||
c. | Allowable tool length | |||
d. | Swing while the tool changes |
6. Determine Support Table or Tailstock
