KORRETTO · Lathe center series
Medium-Duty Live Center
Medium-duty live centers provide balanced support capacity for common shaft and sleeve parts. They are suitable for medium-load turning applications where stability, service life and tailstock support must be considered together.
Send the Morse taper, workpiece weight, machining speed, center hole size and whether a dustproof or oiling structure is required, and we will help check the suitable medium-duty live center series.

Selection Notes
Before selecting a medium-duty live center, confirm the Morse taper, workpiece weight, turning speed, support load and machining environment. If dust, chips or lubrication requirements are important, compare the standard series with the dustproof / oiling series.
FAQ
What is a medium-duty live center used for?
A medium-duty live center is used for rotating tailstock support of workpieces that are larger than light-duty applications but do not require a heavy-duty center. It is suitable for general-purpose turning support with moderate load conditions.
Is it a live center or a dead center?
It is a live center. The center rotates with the workpiece and is selected for medium support loads in turning operations.
What machine taper should be confirmed?
Please confirm the tailstock taper or machine center interface before selection. The medium-duty live center must match the machine taper correctly.
What workpiece weight or support condition should be checked?
Please confirm the workpiece weight, shaft length, center-hole size and support load. These factors determine whether the medium-duty class is suitable.
What speed or load should be considered?
Please confirm the operating speed and support load. The center should be selected according to the actual machining condition and not only by workpiece diameter.
How is it different from light-duty or heavy-duty live centers?
A medium-duty live center fills the range between lighter general work and heavier shaft support conditions. Final choice depends on the actual support load, speed and workpiece size.
What should be checked before installation?
Check the taper fit, center-hole condition, support alignment and operating speed before installation. The contact surfaces should be clean and correctly matched.
What information is needed for quotation?
Please provide the machine taper, workpiece weight, shaft length, center-hole size, speed range and machining process.
