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.

			(compact front but for vertical positioning only)
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
