Hydraulic Expanding Mandrel is an essential work holding device used in machining processes to
securely grip components at high speeds and low feeds.
It plays a crucial role in gear manufacturing, particularly in gear inspection and OD grinding,
where high precision and a wide range of expansion are key advantages.
These mandrels are available in manual and auto-actuated types, with auto-actuated mandrels
achieving centering through the tailstock center by applying axial pressure between the mandrel and
the workpiece.
Hydraulic Expanding Mandrel Applications:
Cylindrical Grinding Parts
Gear Production Machines

Balancing Machines
Supremo Grippings provides repair services for imported hydraulic mandrels commonly used in gear
profile grinding, gear shaving, hobbing, cylindrical grinding, and similar applications.
Seals are replaced and oil refilling is performed during servicing. Please note that jelly-filled
mandrels are not repaired.
If the expanding portion is damaged or cracked, it is replaced. Repairing costs depend upon the
scope of work.
