Selection Notes
Before selecting a high load precision live center, confirm the Morse taper, workpiece weight, shaft length, required accuracy, machining speed and support load. This series is suitable when a high-load live center must also meet higher precision support requirements.
FAQ
What is a high load precision live center used for?
A high load precision live center is used when a workpiece needs both higher support capacity and more stable rotating accuracy from the tailstock side. It is suitable for precision turning support under heavier load conditions.
Is it a live center or a dead center?
It is a live center. It rotates with the workpiece and is selected when precise support is needed under relatively high load conditions.
What machine taper should be confirmed?
Please confirm the tailstock taper or machine interface before selection. The center must match the machine-side taper specification correctly.
What workpiece weight, length or support condition should be checked?
Please confirm the workpiece weight, shaft length, center-hole size and support load. These factors determine whether a precision high-load center is the right choice.
What speed or accuracy requirement should be considered?
Please confirm the operating speed, required support stability and accuracy expectation. Precision live center selection should account for both load capacity and running accuracy.
How is it different from a standard heavy-duty live center?
A standard heavy-duty live center focuses on support load, while a high load precision live center is selected when both load capacity and more controlled support accuracy are important.
What should be checked before installation?
Check the taper fit, center-hole condition, support alignment and working speed before installation. Clean contact surfaces and correct seating are important for precision support.
What information is needed for quotation?
Please provide the machine taper, workpiece weight, shaft length, center-hole size, speed range and required support accuracy.
