FAQ
What is a live center with interchangeable inserts used for?
It is used when one live center body needs to work with different point shapes or support forms. The interchangeable insert structure allows the center to be adapted to different workpiece support requirements.
Is it a live center or a dead center?
It is a live center. The center rotates with the workpiece, and the point or insert can be changed according to the application.
What machine taper should be confirmed?
Please confirm the tailstock taper or machine interface before selection. The center body must match the machine taper correctly.
What insert or point type should be checked?
Please confirm the required point shape, workpiece center-hole form and support condition. The insert type should be selected according to the workpiece end form and machining requirement.
What speed or load should be considered?
Please confirm the operating speed, support load and point type used in the process. The center body and interchangeable insert combination must match the application conditions.
How is it different from a fixed-point live center?
A fixed-point live center uses one built-in point shape. An interchangeable insert live center allows the point style to be changed, which is useful for multiple workpiece support conditions.
What should be checked before installation?
Check the machine taper, insert type, locking condition, center-hole form and support alignment before installation. The insert and body contact surfaces should be clean and securely fitted.
What information is needed for quotation?
Please provide the machine taper, required insert type, workpiece drawing, support load, speed range and machining process.
